By this action, the Commission proposes to simplify the rules for the common carrier and private operational fixed services, currently contained respectively in Parts 21 and 94 of the Commission's Rules, and to consolidate those rules into a new Part 101. The key objectives in this Notice of Proposed Rulemaking (Notice) are to restructure the fixed microwave rules so that they are easier for the public to understand and use, to conform similar rule provisions to the maximum extent possible, to eliminate redundancy, and to remove obsolete language. We are also taking this opportunity to review the need for and impact of certain regulatory requirements and policies. 2. Common carrier microwave services and private operational fixed microwave services share many of the same frequency bands and use substantially the same equipment. As a result of recent changes that are discussed below, the interference standards, antenna standards, and coordination procedures for private and common carrier fixed microwave services have further converged. This rulemaking is an effort to conform filing, processing, operational, and technical requirements for services that are technically similar and, thereby, to gain significant economies and alleviate confusion to the public. BACKGROUND 3. Communications services that use the microwave spectrum for fixed services include common carriers (currently regulated by Part 21 of the FCC Rules), common carrier multiple address systems (Part 22), broadcasters (Part 74), cable TV operators (Part 78), and private operational fixed users (currently regulated by Part 94). The radio frequency spectrum is allocated among these services on either a shared or an exclusive basis. When different service users have similar needs, they are sometimes required to share spectrum bands. 4. Of the services listed above, the common carrier and private operational fixed microwave users are the most similar in technical requirements and share the most frequency bands. The convergence of the common carrier and private operational fixed microwave technical standards has occurred over the last decade as a result of several rulemaking proceedings. Recently, a further convergence of these two services occurred as a result of the reallocation of five bands above 3 GHz on a co-primary basis to the common carrier and private operational fixed microwave licensees that are relocating from the 1850-1990, 2110- 2150, and 2160-2200 MHz bands (2 GHz bands) to accommodate Personal Communications Services (PCS) and other emerging technologies. Although the emerging technologies proceeding resolved all the technical issues necessary for this reallocation, there were other technical matters raised in the proceeding, which were not considered critical to the 2 GHz microwave users' relocation to other regions of the spectrum, that were left to be settled in a future proceeding. 5. Also, as a result of the emerging technologies spectrum reallocation and the resulting increase in frequency band-sharing, common carrier and private microwave industry members have united to develop joint interference standards and coordination procedures. For over a year, a subcommittee of the Telecommunications Industry Association's Fixed Point-to-Point Microwave Engineering Committee (TIA TR14.11 Interference Criteria Engineering Subcommittee) has held joint meetings with the National Spectrum Managers Association (NSMA), a group of frequency coordinators for Part 21 applicants, to determine interference criteria for Part 21 and Part 94 users. This collaboration has resulted in a revised TIA Telecommunications Systems Bulletin TSB 10-F, "Interference Criteria for Microwave Systems," (TSB 10-F) which was adopted by the microwave industry on May 31, 1994. Representatives from both the TIA fixed microwave group and the NSMA have met with Commission staff to discuss the benefits of common technical standards, processing procedures, and consolidated rules for common carrier and private operational fixed microwave users. 6. Another factor necessitating this proceeding is that the majority of the license application processing for the Part 21 and Part 94 microwave services is now being handled by the Wireless Telecommunications Bureau's Licensing Division in Gettysburg, Pennsylvania. Because the application processing for these services was formerly performed by different Commission offices, the processing practices and policies differed. This proceeding seeks to bring uniformity to the fixed microwave application processing procedures. 7. The Part 21 and Part 94 rules need to be consolidated, conformed, and updated to allow the microwave industry to operate as efficiently as possible without being hampered by obsolete regulations. Because of the commonality of major portions of the existing common carrier and private operational fixed microwave rules and the industry move to create common standards and coordination procedures, we believe it would be beneficial to consolidate these rules into one comprehensive part. At the same time, this proceeding provides us with an opportunity to improve the organization of the microwave rules, to simplify them, to eliminate unnecessary language, and to make other substantive amendments. We expect that a new consolidated Part 101 will result in major benefits. First, the public will benefit because of a much simplified and streamlined licensing process. Second, the improvements in processing efficiency will save scarce Commission resources and free staff time to improve service to the public. Third, we expect the proposed rules to encourage more efficient use of the microwave spectrum. Finally, common technical standards for common carrier and private microwave equipment may lead to economies of scale in microwave equipment production and, thus, lower equipment prices to users. DISCUSSION 8. Proposed Part 101 is approximately 65 percent the volume of the current common carrier and private radio fixed microwave rules. This reduction results from the elimination of repetitive sections such as definitions, application procedures, and processing procedures, the elimination of unnecessary language, and the consolidation of the remaining rules. In the paragraphs below we address the proposed changes for each subpart and section of the rules, other than proposed changes that are editorial in nature or that concern only renumbering of existing rule language. Appendix B, entitled "Cross-Reference Index," shows the disposition of each existing rule in Parts 21 and 94. 9. We welcome comments on whether the scope of our consolidation effort is appropriate. We ask that comments identify the subject of their remarks, whenever possible, by citing the proposed section number of a rule (with cross-reference to the old rule as necessary). This identification will expedite and simplify our review of the comments on the many proposals contained in this Notice. General Requirements 10. Definitions. We propose to make minor editorial changes in the definitions where appropriate. In instances where a definition now appears in more than one rule section and is phrased inconsistently, we propose to use the phrasing that we believe to be the most precise. In cases where a definition appears in Part 2 of the Rules as well as in another part, the proposed Part 101 definition adopts the Part 2 definition in order to conform with either the International Telecommunication Convention or the international Radio Regulations. Additionally, we propose to change the name and all relevant terms related to the Private Digital Termination System service to match the name and terms of the identical Common Carrier Digital Electronic Message Service. See proposed Section 101.3. Applications and Licenses 11. General Application Requirements. We propose to eliminate several application showings that are currently required of common carrier microwave applicants under Part 21 of the rules, but which are not essential for processing these applications. We request comments on each of these proposals. First, we propose to eliminate the financial showing required under  21.13(a)(2) and 21.17. Lack of financing has generally not been a problem in the common carrier services being transferred to Part 101, and we consider a certification of financial ability unnecessary in these services. Second, we propose eliminating the public interest showing required under  21.13(a)(4). We tentatively conclude that the public interest will generally be served by granting applications in these services that meet all the Commission's other rules and requirements, and that a separate statement from the applicant pursuant to  21.13(a)(4) is unnecessary. We also note that the Commission can still request a separate public interest showing if this is deemed necessary in any particular case. Third, we propose eliminating the requirement that applicants submit a copy of any franchise or other authorization when such authorizations are required by local law. See  21.13(f). We request comments on whether we should replace this application showing with a rule, similar to that contained in Part 22 of the rules, stating that applicants must comply with all local franchise or authorization requirements, obtain any local authorizations by the end of the construction period, and notify the Commission if local authorization is denied. See  22.13(f). Fourth, we propose eliminating showings regarding control over the station, see  21.13(g), and maintenance procedures, see  21.15(e). We request comments on whether we should replace these showings with a general rule describing a licensee's responsibilities for maintenance and control of the station and requiring that maintenance contracts must be in writing. See  22.205. We also request comments on whether we should continue to require the address and telephone number of a maintenance center or person responsible for technical operation, see  21.15(e)(1) and Item 18 of FCC Form 494 ("Application for New or Modified Microwave Radio Station License Under Part 21"), or whether this requirement is unnecessary and should also be deleted. Fifth, we propose to eliminate the vertical profile sketch, see  21.15(c), and the site availability showing, see  21.15(a), as these showings are not necessary for processing and lack of site availability has not been a problem in the common carrier services being transferred to Part 101. Sixth, we request comments on whether the public interest showing currently required of applicants in the Point-to-Point Microwave Radio Service pursuant to  21.706(a) should be retained or deleted. We also propose to allow electronic filing for all fixed microwave services authorized under Part 101 as is currently allowed for private land mobile applications. See proposed Sections 1.743, 1.913, and 101.37. Finally, we request comments on what requirements we should adopt regarding retention or posting of the station license. See e.g.  21.201, 22.201, and 94.107. 12. Licensee Qualifications and Consummation of Assignments and Transfers. Under Part 21, applicants and licensees are currently required to provide ownership and character information on FCC Form 430 ("Licensee Qualification Report"), see  21.11(a), and to disclose the real party in interest behind the application pursuant to  21.13(a)(1). See also  21.305. We request comment on precisely what ownership (including partnership) and character information we should continue to require of common carrier applicants and licensees under the new Part 101. In addition, under  21.11(d), (e), and (f), applicants are required to complete assignments or transfers of control within 45 days of the date of authorization and to notify the Commission within 10 days of consummation. In the common carrier services being transferred to Part 101, applicants frequently request extensions of time to complete assignments or transfers. Such requests are routinely granted. Based on this experience, we request comment on whether the time for consummation of assignments and transfers should be extended to 360 days or longer, or whether applicants should be allowed merely to notify the Commission of failure to consummate, rather than requiring applicants to file, and the Commission to grant, repeated extension requests. We also propose to eliminate the requirement for common carriers to notify the Commission within 10 days of consummation. 13. Commencing Operation. With regard to the requirement for stations to be placed in operation within a certain period after the date of grant, it has been common practice among some applicants to request and obtain a modification of their license and thereby obtain additional time within which to be in operation. Some applicants repeated this procedure several times, thereby extending their operational deadline far beyond the period contemplated by the rules. In response to these perceived abuses, the Commission's Private Radio Bureau Licensing Division issued a Public Notice clarifying that a station must be placed in operation within the time required by current  94.51 irrespective of whether the licensee had been granted an amendment to its station authorization. We propose to codify this longstanding interpretation of our rule. See proposed Section 101.63. 14. Although current  94.51 requires that private fixed microwave stations be placed in operation within a time certain, it does not define what constitutes operation for purposes of the rules. In the past, several applicants have argued that the transmission of color bars or other types of strictly test signals satisfies the rule's requirement of being in operation. This interpretation has been uniformly rejected by the staff. Applicants have also argued that the  94.51 requirement of being in operation is satisfied as long as the station is simply capable of transmitting intelligence. The staff, however, has consistently informed the public that the mere capability of transmission does not satisfy the requirement of being in operation. We are proposing in Section 101.67(d) to make it clear that only the transmission of operational signals is sufficient to satisfy the "in operation" requirement and that neither the capability of transmission nor the transmission of color bars or similar test signals satisfies the requirement to be in operation. We are proposing to apply this requirement to both private and common carrier fixed microwave users, as the underlying basis for this proposal, efficient spectrum usage, applies equally to both groups. We request comment on whether this requirement is necessary or applicable for common carrier licensees under proposed Part 101. Technical Standards 15. Frequency Availability Chart. A new frequency availability chart has been placed in the proposed rules (proposed Section 101.101) for the convenience of licensees and applicants. In addition to showing the frequency availability for private and common carrier users, it also shows other services, such as broadcast, cable, PCS, MDS, and ITFS, that share the same bands. More specific technical information for the common carrier and private microwave services are contained in rule Subparts G through J. 16. Coordination Procedures and Interference Standards. In the Second Report and Order in ET Docket 92-9, the Commission adopted the current Part 21 coordination procedures and the current Part 94 interference standards for the relocated common carrier and private operational fixed microwave users. As stated above and in the Second Report and Order, the common carrier and private microwave industry members have united to develop joint interference standards and coordination procedures. We propose, therefore, to apply the same coordination procedures and interference standards to all bands for both private and common carrier fixed microwave services. In addition, we propose to modify the present coordination procedures and interference protection standards to be consistent with the TIA industry standards. See proposed Sections 101.103 and 101.105. 17. Transmitter Power Limitations. In addition to merging the transmitter power table from Parts 21 and 94, we also propose to eliminate the values for maximum allowable transmitter power, while retaining the values for Equivalent Isotropic Radiated Power (EIRP). See proposed Section 101.113. We are proposing to allow a maximum EIRP of + 55 dBW for all point-to-point microwave bands from 4 GHz to 40 GHz, to allow for increased path reliability on long paths and to set a common standard for all bands. See proposed Section 101.113. This proposal is based partly on TIA recommendations. Comsearch also proposed a maximum allowable EIRP of +55 dBW in an earlier proceeding. Comsearch points out that in Part 25 of the Rules, the terrestrial station EIRP used to determine frequency coordination distance in the 4, 6, and 11 GHz bands is +55 dBW, which corresponds with the International Telecommunications (ITU) Radio Rules and Regulations. The Commission decided not to act on that portion of Comsearch's petition, instead deferring consideration of maximum authorized power, antenna standards, and ATPC to a future proceeding. We seek comment on whether increasing the transmitter power limitations as proposed would have any negative impact on any radio users. 18. Automatic Transmitter Power Control. ATPC is a feature of digital microwave radio that automatically adjusts transmitter output power based on path fading detected at the far-end receiver(s). In the emerging technologies/relocation proceeding, commenters proposed that ATPC should be explicitly authorized in the rules. In response, the Commission clarified in the rules that ATPC is permitted up to a 3 dB increase in power and encouraged industry groups to explore in greater detail under what circumstances ATPC should be authorized and whether a greater increase in power than 3 dB would be appropriate. We have reviewed the ATPC guidelines in TSB 10-F and are still uncertain of the necessity of including explicit provisions for its use in the rules. We seek comment on whether it is necessary to have TIA's recommendations for ATPC implementation included in our Rules. TSB 10-F contains provisions for up to three different power level specifications: maximum transmit power, coordinated transmit power, and nominal transmit power. We also seek comment on how these recommendations for ATPC should be implemented under our current licensing scheme, which authorizes only a single operating power level on each license, with that power being the one used in the coordination process. If the use of ATPC as described in TSB 10-F were to be permitted, what changes would the Commission have to make to its forms, licenses, and data base? 19. Antenna Standards. All antenna standards for Part 101 services have been consolidated into one rule section (proposed section 101.115). Few substantive changes to the antenna standards are proposed. In the Docket 92-9 proceeding, commenting parties raised concerns about our existing antenna standards, stating that the category A standards should be updated and that a new detailed definition of congested areas should be specified to maximize efficiency and permit full use of available bands. The Commission does not have sufficient information at this time to propose specific changes to these standards. Developmental Authorizations 20. We propose to eliminate the general requirement that applicants report on any patents applied for as a result of a developmental authorization. This information is in the public domain when the patent is granted, and our requirement is, therefore, duplicative. We also propose to modify the language concerning the confidentiality of developmental reports to make it consistent with our general rules on requests for confidentiality. The consolidated rules continue the prohibition on providing service for hire with a developmental grant now placed on common carriers and extends the prohibition against commercial operation of a developmental grant to private radio operators. CONCLUSION 21. In this Notice, we have proposed to amend the regulations for the common carrier and private operational fixed microwave services by consolidating and simplifying their present rule parts, contained respectively in Parts 21 and 94 of the Commission's Rules, to create a new Part 101. Our specific proposals are contained in the rules appendix. We solicit comment on them. We also invite comment on any additional changes that can make the Commission's microwave rules more "user friendly" and help the staff provide improved service to the public. PROCEDURAL MATTERS 22. Initial Regulatory Flexibility Analysis. Pursuant to the Regulatory Flexibility Act of 1980, the Commission finds as follows: A. Reason for Action This rulemaking proceeding is initiated to obtain comment regarding consolidation and simplification of the microwave rules now contained in Parts 21 and 94 of Title 47 of the Code of Federal Regulations. B. Objectives This action would reduce redundancy now contained in the rules and remove obsolete rules and language. It would also simplify and clarify the requirements for filing license and other authorization applications, the processing of applications and other requests, and the operation of common carrier and private operational fixed microwave stations. C. Legal Basis The proposed action is authorized by Sections 4(i) and 303(r) of the Communications Act of 1934, as amended, 47 U.S.C.  154(i) and 303(r). D. Description, Potential Impact, and Number of Small Entities Affected This reorganization and revision of the common carrier and private operational fixed microwave rules will reduce the volume of the rules by approximately 25 percent and make them easier to use and understand. Both the reduction in volume and consolidation of the rules should improve their usefulness as they will be more easily understood by, and save research time for, the public. The benefits would accrue to all interested parties, large and small entities alike. We invite specific comment by interested parties on the likely magnitude of the impact on small radio manufactures and suppliers. E. Reporting, Record Keeping, and Other Compliance Requirements There should be an overall decrease in reporting, record keeping, and other compliance requirements. The use of electronic filing alone should greatly reduce the amount of paperwork required to be filed and increase speed of service. F. Federal Rules that Overlap, Duplicate or Conflict with these Rules None. G. Significant Alternatives Minimizing Impact on Small Entities Consistent with Stated Objectives The objective of this proceeding is to minimize confusion, research time, record keeping and recording for users of microwave radio frequencies. We are unaware of other alternatives that would be as desirable. We solicit comments on this point. 23. Other Matters. This is a non-restricted notice and comment rulemaking proceeding. Ex parte presentations are permitted, provided they are disclosed as provided in the Commission's rules. See generally 47 C.F.R.  1.1202, 1.1203, and 1.1206(a). 24. This action is taken pursuant to Section 4(i) and 303(r) of the Communications Act of 1934, as amended, 47 U.S.C. Sections 154(i) and 303(r). 25. Pursuant to applicable procedures set forth in Sections 1.415 and 1.419 of the Commission's Rules, interested parties may file comments on or before [30 days after publication in the FR], and reply comments on or before [45 days after FR publication]. All relevant and timely comments will be considered by the Commission before final action is taken in this proceeding. To file formally in this proceeding, participants must file an original and four copies of all comments, reply comments, and supporting comments. If participants want each Commissioner to receive a personal copy of their comments, an original plus nine copies must be filed. Comments and reply comments should be sent to Office of the Secretary, Federal Communications Commission, Washington, D.C. 20554. Comments and reply comments will be available for public inspection during regular business hours in the Reference Center (Room 239) of the Federal Communications Commission, 1919 M Street, N.W., Washington D.C. 20554. 26.

Section 21.2 is amended to read as follows:  21.2 Definitions. As used in this part: Antenna power gain. The square of the ratio of the root-mean-square free space field intensity produced at one mile in the horizontal plane, in millivolts per meter for one kilowatt antenna input power to 137.6 mV/m. This ratio should be expressed in decibels (dB). (If specified for a particular direction, antenna power gain is based on the field strength in that direction only.) Antenna power input. The radio frequency peak or RMS power, as the case may be, supplied to the antenna from the antenna transmission line and its associated impedance matching network. Antenna structures. The antenna, its supporting structure and anything attached to it. Assigned frequency. The frequency coinciding with the center of the radio frequency channel in which the station is authorized to work. This frequency does not necessarily correspond to any frequency in an emission. Authorized bandwidth. The maximum width of the band of frequencies permitted to be used by a station. This is normally considered to be the necessary or occupied bandwidth, whichever is greater. Authorized frequency. The frequency assigned to a station by the Commission and specified in the instrument of authorization. Authorized power. The maximum power a station is permitted to use. This power is specified by the Commission in the station's authorization. Bandwidth occupied by an emission. The band of frequencies comprising 99 percent of the total radiated power extended to include any discrete frequency on which the power is at least 0.25 percent of the total radiated power. Bit rate. The rate of transmission of information in binary (two state) form in bits per unit time. Carrier. In a frequency stabilized system, the sinusoidal component of a modulated wave whose frequency is independent of the modulating wave; or the output of a transmitter when the modulating wave is made zero; or a wave generated at a point in the transmitting system and subsequently modulated by the signal; or a wave generated locally at the receiving terminal which when combined with the side bands in a suitable detector, produces the modulating wave. Carrier frequency. The output of a transmitter when the modulating wave is made zero. Communication common carrier. Any person engaged in rendering communication service for hire to the public. Control point. A control point is an operating position at which an operator responsible for the operation of the transmitter is stationed and which is under the control and supervision of the licensee. Control station. A fixed station whose transmissions are used to control automatically the emissions or operations of another radio station at a specified location, or to transmit automatically to an alarm center telemetering information relative to the operation of such station. Coordination distance. For the purpose of this part, the expression "coordination distance" means the distance from an earth station, within which there is a possibility of the use of a given transmitting frequency at this earth station causing harmful interference to stations in the fixed or mobile service, sharing the same band, or of the use of a given frequency for reception at this earth station receiving harmful interference from such stations in the fixed or mobile service. Digital modulation.

Waivers of these rules may be granted upon application or on the Commission's own motion. A request for waiver shall contain a statement of reasons sufficient to justify a waiver. A waiver will not be granted except upon an affirmative showing that: (a) The underlying purpose of the rule will not be served, or would be frustrated, by its application in the particular case, and that grant of the waiver is otherwise in the public interest; or (b) The unique facts and circumstances of a particular case render application of the rule inequitable, unduly burdensome or otherwise contrary to the public interest. Applicants must also show the lack of a reasonable alternative.  101.25 Inconsistent or conflicting applications. While an application is pending and undecided, no subsequent inconsistent or conflicting application may be filed by the same applicant, the applicant's successor or assignee, or on behalf or for the benefit of the same applicant, the applicant's successor or assignee.  101.27 Repetitious applications. (a) Where an applicant has been afforded an opportunity for a hearing with respect to a particular application for a new station, or for an extension or enlargement of a service or facilities, and the Commission has, after hearing or default, denied the application or dismissed it with prejudice, the Commission will not consider a like application involving service of the same kind to the same area by the same applicant, or by the applicant's successor or assignee, or on behalf of or for the benefit of the original parties in interest, until after the lapse of 12 months from the effective date of the Commission's order. The Commission may, for good cause shown, waive the requirements of this section. (b) Where an appeal has been taken from the action of the Commission denying a particular application, another application for the same class of station and for the same area, in whole or in part, filed by the same applicant or by the applicant's successor or assignee, or on behalf or for the benefit of the original parties in interest, will not be considered until the final disposition of such appeal.  101.29 Amendment of pending applications. (a) Any pending application may be amended as a matter of right if the application has not been designated for hearing, or for comparative evaluation pursuant to  101.51, or for the random selection process, provided, however, that the amendments must comply with the provisions of  101.41 as appropriate. (b) Requests to amend an application designated for hearing or for comparative evaluation, or tentatively selected by the random selection process may be granted only if a written petition demonstrating good cause is submitted and properly served upon the parties of record. (c) The Commission will classify amendments on a case-by-case basis. Whenever previous amendments have been filed, the most recent amendment will be classified by reference to how the information in question stood as of the latest Public Notice issued which concerned the application. An amendment will be deemed to be a major amendment subject to Sec. 101.37 and Sec. 101.45 under any of the following circumstances: (1) if the amendment results in a substantial modification of the engineering proposal such as (but not necessarily limited to): (i) A change in, or an addition of a radio frequency channel; (ii) A change in polarization of the transmitted signal; (iii) An increase in the transmitter output power of three (3) dB or more in the Private Fixed, Point-to-Point, and Local Television Transmission Services; (iv) A change in type of transmitter emission or an increase in emission bandwidth requiring a larger authorized bandwidth; (v) A change in the geographic coordinates of a station's transmitting antenna of more than ten (10) seconds of latitude or longitude, or both; (vi) A change of more than one (1) degree in the azimuth of the center of the main lobe of radiation of a point-to-point station's transmitting antenna (including any deflections by repeating devices); (vii) Any change which increases the antenna center line height to a new height that would trigger a requirement for a new aeronautical study; or (viii) Any changes or combination of changes which would cause harmful electrical interference to an authorized facility or result in a mutually exclusive conflict with another pending application; or (ix) Any technical change that would increase the effective radiated power in any direction by more than one and one-half (1.5) dB in the Digital Electronic Message Service. (2) If the amendment would convert a proposal, such that it may have a significant impact upon the environment under Sec. 1.1307 of the Commission's rules, which would require the submission of an environmental assessment, see Sec. 1.1311 of this chapter, and Commission environmental review, see Secs. 1.1308 and 1.1312 of this chapter. (3) If the amendment results in a substantial and material alteration of the proposed service. (4) If the amendment specifies a substantial change in beneficial ownership or control (de jure or de facto) of an applicant such that the change would require, in the case of an authorized station, the filing of a prior assignment or transfer of control application under section 310(d) of the Communications Act of 1934 [47 U.S.C. 310(d)]. Such a change would not be considered major where the assignment or transfer of control is for legitimate business purposes other than the acquisition of applications. (5) If the amendment, or the cumulative effect of the amendment, is determined by the Commission otherwise to be substantial pursuant to section 309 of the Communications Act of 1934. (d) The applicant must serve copies of any amendments or other written communications upon the following parties: (1) Any applicant whose application appears on its face to be mutually exclusive with the application being amended, including those applicants originally served under  101.509; (2) Any applicant whose application has been found by the Commission, as published in a public notice, to be mutually exclusive with the application being amended; and (3) Any party who has filed a petition to deny the application or other formal objection, when that petition or formal objection has not been resolved by the Commission. (e) The Commission may waive the service requirements of paragraph (d) of this section and prescribe such alternative procedures as may be appropriate under the circumstances to protect petitioners' interests and to avoid undue delay in a proceeding, if an applicant submits a request for waiver which demonstrates that the service requirement is unreasonably burdensome. Requests for waiver must be served on petitioners. Oppositions to the petition may be filed within five (5) days after the petition is filed and must be served on the applicant. Replies to oppositions will not be entertained. (f) Any amendment to an application must be signed and must be submitted in the same manner, and with the same number of copies, as was the original application. Amendments may be made in letter form if they comply in all other respects with the requirements of this chapter.  101.31 Special temporary authority. (a) In circumstances requiring immediate or temporary use of facilities, request may be made for special temporary authority to install and/or operate new or modified equipment. Any such request may be submitted as an informal application in the manner set forth in Section 101.9 and must contain full particulars as to the proposed operation including all facts sufficient to justify the temporary authority sought and the public interest therein. No such request will be considered unless the request is received by the Commission at least 10 days prior to the date of proposed construction or operation or, where an extension is sought, expiration date of the existing temporary authorization. (b) Special temporary authorization may be granted upon written request in the following circumstances: (1) In emergency situations; (2) to permit restoration or relocation of existing facilities to continue communication service; (3) to conduct tests to determine necessary data for the preparation of an application for regular authorization; (4) for a temporary, non-recurring service where a regular authorization is not appropriate; (5) in other situations involving circumstances which are of such extraordinary nature that delay in the institution of temporary operation would seriously prejudice the public interest. (c) The Commission may grant requests for special temporary authority without issuing the public notice provided for in 1.962 of this chapter for periods not exceeding 180 days, if there are extraordinary circumstances supporting the request and where delay in commencing temporary operation would seriously prejudice the public interest. Requests for special temporary authorization not involving extraordinary circumstances may be granted without public notice for a period of 30 days where an application for regular operation is not contemplated or for 60 days pending or after the filing of an application for regular operation. (d) Request for special temporary authority must contain the following information: (1) Name, address, and citizenship status of applicant; (2) Need for special action, including a description of any emergency or damage to equipment; (3) Type of operation to be conducted; (4) Purpose of operation; (5) Time and date of operation desired; (6) Class of station and nature of service; (7) Location of station and points with which station will communicate; (8) Equipment to be used, specifying manufacturer, model number, and number of units; (9) Frequency(s) desired. (10) Azimuth and beamwidth of major lobe of transmitting antenna and ERP; (11) Type of emission; (12) Description of antenna to be used, including height. (13) Certification that neither the applicant nor any party to the applicant is subject to a denial of Federal benefits that includes FCC benefits pursuant to section 5301 of the Anti- Drug Abuse Act of 1988, as required by 1.2002 of this Chapter.  101.33 Who may sign applications. See Part 1 of this chapter Sections 1.743 and 1.913, for practices and procedures governing signatures on applications, amendments and related statements of fact.. Processing of Applications  101.35 Preliminary processing of applications. (a) Applications received for filing are given a file number. The assignment of a file number to an application is for administrative convenience and does not indicate the acceptance of the application for filing and processing and does not preclude the subsequent return of the application. (b) Applications that are incomplete with respect to answers, supplementary statements, execution, or other matters of a formal character will be considered defective and may be returned to the applicant with a brief statement as to such defects. If an applicant is requested by the Commission to file any additional documents or information not included in the prescribed application form, failure to comply with such request will be deemed to render the application defective, and such application may be dismissed. Applications will also be deemed to be defective and may be returned to the applicant in the following cases: (1) Statutory disqualification of applicant; (2) Proposed use or purpose of station would be unlawful; (3) Requested frequency is not allocated for assignment for the service proposed; (4) The submitted filing fee (if required) is insufficient; (5) The application does not demonstrate compliance with the special requirements applicable to the radio service involved; (6) The applications does not include all necessary exhibits; (7) The application fails to meet any other Commission requirements. (c) Any application that has been returned to the applicant for correction will be processed in original order of receipt when resubmitted if it is received within 60 days from the date on which it was returned to the applicant and the change does not involve a major amendment. If the application is not resubmitted within the prescribed time, it will be treated as a new application and considered at the time other applications received on the same date are considered. (d) Applications considered defective under paragraph (b) of this section may be accepted for filing if: (1) The application is accompanied by a request which sets forth the reasons in support of a waiver of (or an exception to), in whole or in part, any specific rule, regulation, or requirement with which the application is in conflict; or (2) The Commission, upon its own motion, waives (or allows an exception to), in whole or in part, any rule, regulation or requirement.  101.37 Public notice period. (a) At regular intervals, the Commission will issue a public notice listing: (1) The acceptance for filing of applications and major amendments thereto; (2) Significant Commission actions concerning applications; (3) The receipt of applications for minor modifications made pursuant to Sec. 101.59; (4) Information which the Commission in its discretion believes of public significance; and (5) Special environmental considerations as required by Part 1 of this chapter. (b) A public notice will not normally be issued for any of the following applications: (1) For authorization of a minor technical change in the facilities of a proposed or authorized station where such a change would not be classified as a major amendment to a pending application, as defined by  101.29, or as a minor modification to a license pursuant to  101.59; (2) For temporary authorization pursuant to  101.31; (3) For an authorization under any of the proviso clauses of section 308(a) of the Communications Act of 1934 (47 U.S.C. 308(a)); (4) For consent to an involuntary assignment or transfer of control of a radio authorization; or (5) For consent to a voluntary assignment or transfer of control of a radio authorization, where the assignment or transfer does not involve a substantial change in ownership or control. (c) Except as otherwise provided in this Part (e.g., Sec. 101.59), no application that has appeared on public notice will be granted until the expiration of a period of thirty days following the issuance of the public notice listing the application, or any major amendment thereto, or until the expiration of a period of thirty days following the issuance of a public notice identifying the tentative selectee of a random selection process, whichever is later. (d) The listing of an application on public notice as accepted for filing does not indicate that the application has been found by the Commission to be acceptable for filing and does not preclude the subsequent return of the application.  101.39 Dismissal and return of applications. (a) Except as provided under paragraph (d) of this Section and under  101.41, any application may, upon written request, be dismissed without prejudice as a matter of right prior to the adoption date of any final Commission action or the application's designation for hearing or comparative evaluation. (b) Applicants for stations licensed under Subpart H (Private Operational Fixed Microwave Service) may request the return of an application for correction without dismissal. (c) A request to dismiss an application without prejudice will be considered after designation for hearing, after selection through the comparative evaluation procedure of  101.51, or after selection as a tentative selectee in a random selection proceeding, only if: (1) A written petition is submitted to the Commission and, in the case of applications designated for hearing or comparative evaluation, is properly served upon all parties of record; (2) The petition is submitted before the issuance date of a public notice of Commission action denying the application; and (3) The petition complies with the provision of  101.41 (whenever applicable) and demonstrates good cause. (d) Except as provided under  101.41, an application designated for inclusion in the random selection process may be dismissed without prejudice as a matter of right if the applicant requests its dismissal at least 2 days prior to a random selection proceeding. (e) Dismissal for failure to prosecute or for failure to respond to official correspondence or requests for additional information within a specified time period will be without prejudice prior to its designation for hearing, or tentative selection by the random selection process. Dismissal may be with prejudice after selection of the comparative evaluation process, or after selection as a tentative selectee in a random selection proceeding.  101.41 Ownership changes and agreements to amend or dismiss applications or pleadings. (a) Except as provided in paragraph (b) of this section, applicants or any other parties in interest to pending applications must comply with the provisions of this section whenever: (1) They participate in any agreement (or understanding) which involves any consideration promised or received, directly or indirectly, including any agreement (or understanding) for merger of interests or the reciprocal withdrawal of applications; and (2) The agreement (or understanding) may result in either: (i) A proposed substantial change in beneficial ownership or control (dejure or de facto) of an applicant such that the change would require, in the case of an authorized station, the filing of a prior assignment or transfer of control application under  310(d) of the Communications Act of 1934 [47 U.S.C.  310(d)], or (ii) Proposed withdrawal, amendment or dismissal of any application(s), amendment(s), petition(s), pleading(s), or any combination thereof, which would thereby permit the grant without hearing, comparative evaluation under of Sec. 101.51, or random selection of an application previously in contested status. (b) The provisions of this section will not be applicable to any engineering agreement (or understanding) that: (1) Resolves frequency conflicts with authorized stations or other pending applications without the creation of new or increased frequency conflicts; and (2) Does not involve any consideration promised or received, directly or indirectly (including any merger of interests or reciprocal withdrawal of applications), other than the mutual benefit of resolving the engineering conflict. (c) For any agreement subject to this section, the applicant of an application which would remain pending pursuant to such an agreement will be considered responsible for the compliance by all parties with the procedures of this section. Failure of the parties to comply with the procedures of this section will constitute a defect in those applications which are involved in the agreement and remain in a pending status. (d) The principals to any agreement or understanding subject to this section must comply with the standards of paragraph (e) of this section in accordance with the following procedure: (1) Within ten (10) days after entering into the agreement, the parties thereto must jointly notify the Commission in writing of the existence and general terms of such agreement, the identity of all of the participants and the applications involved; (2) Within thirty (30) days after entering into the agreement, the parties thereto must file any proposed application amendments, motions, or requests together with a copy of the agreement which clearly sets forth all terms and provisions, and such other facts and information as necessary to satisfy the standards of paragraph (e) of this section. Such submission must be accompanied by the certification by affidavit of each principal to the agreement declaring that the statements made are true, complete, and correct to the best of their knowledge and belief, and are made in good faith. (3) The Commission may request any further information which in its judgment it believes is necessary for a determination under paragraph (e) of this section. (e) The Commission will grant an application (or applications) involved in the agreement (or understanding) only if it finds upon examination of the information submitted, and upon consideration of such other matters as may be officially noticed, that the agreement is consistent with the public interest, and the amount of any monetary consideration and the cash value of any other consideration promised or received is not in excess of those legitimate and prudent costs directly assignable to the engineering, preparation, filing and advocacy of the withdrawn, dismissed, or amended application(s), amendment(s), petition(s), pleading(s), or any combination thereof. Where such costs represent the applicant's in-house efforts, these costs may include only directly assignable costs and must exclude general overhead expenses. [The treatment to be accorded such consideration for interstate rate making purposes will be determined at such time as the question may arise in an appropriate rate proceeding.] An itemized accounting must be submitted to support the amount of consideration involved except where such consideration (including the fair market value of any non-cash consideration) promised or received does not exceed one thousand dollars ($1,000.00). Where consideration involves a sale of facilities or merger of interests, the accounting must clearly identify that portion of the consideration allocated for such facilities or interests and a detailed description thereof, including estimated fair market value. The Commission will not presume an agreement (or understanding) to be prima facie contrary to the public interest solely because it incorporates a mutual agreement to withdraw pending application(s), amendment(s), petition(s), pleading(s), or any combination thereof.  101.43 Opposition to applications. (a) Any party in interest may file with the Commission a petition to deny any application for which public notice is required. All such petitions must: (1) Identify the application or applications including applicant's name, station location, Commission file numbers and radio service involved with which it is concerned; (2) Be filed in accordance with the pleading limitations, filing periods, and other applicable provisions of this Part and Part 1; (3) Contain specific allegations of fact (except for those of which official notice may be taken), supported by affidavit of a person or persons with personal knowledge thereof and be sufficient to make a prima facie showing that the petitioner is a party in interest and that a grant of the application would be inconsistent with the public interest, convenience and necessity; (4) Be filed within thirty (30) days after the date of public notice announcing the acceptance for filing of such applications or major amendments thereto, or, identifying the tentative selectee of a random selection proceeding (unless the Commission otherwise extends the deadline); and (5) Contain a certificate of service showing that the applicant has been mailed a copy of the petition no later than the date on which the petition is filed with the Commission. (b) The applicant may file an opposition to any petition to deny and the petitioner may file a reply thereto in which allegations of fact or denials thereof must be supported by an affidavit of a person or persons with personal knowledge thereof and be clearly identified. The applicant must serve a copy of the opposition on the petitioner, and the petitioner must serve a copy of its reply on the applicant. The time for filing such oppositions and replies are provided in  1.45. (c) Notwithstanding the provisions of paragraph (a) of this section, before Commission action on any application for an instrument of authorization, any person may file informal objections to the grant. The Commission will consider informal objections, but not necessarily discuss them in a written opinion, if the objection is filed at least one day prior to action on the application and the objection is signed by the submitting person with a disclosure of that person's interest. Such objections may be submitted in letter form. The limitation on pleadings and time for filing pleadings provided for in  1.45 will not be applicable to any objections duly filed pursuant to this paragraph. (d) Petitions to deny not filed in accordance with paragraph (a) of this section will be treated as informal objections.  101.45 Mutually exclusive applications. (a) The Commission will consider applications to be mutually exclusive if their conflicts are such that the grant of one application would effectively preclude by reason of harmful electrical interference, or other practical reason, the grant of one or more of the other applications. The Commission will presume "harmful electrical interference" to mean interference which would result in a material impairment to service rendered to the public despite full cooperation in good faith by all applicants or parties to achieve reasonable technical adjustments which would avoid electrical conflict. (b) A common carrier application will be entitled to be included in a random selection process or to comparative consideration with one or more conflicting applications only if: (1) The application is mutually exclusive with the other application; and (2) The application is received by the Commission in a condition acceptable for filing by whichever "cut-off" date is earlier: (i) Sixty (60) days after the date of the public notice listing the first of the conflicting applications as accepted for filing; or (ii) One (1) business day preceding the day on which the Commission takes final action on the previously filed application (should the Commission act upon such application in the interval between thirty (30) and sixty (60) days after the date of its public notice). (c) Whenever three or more applications are mutually exclusive, but not uniformly so, the earliest filed application established the date prescribed in paragraph (b)(2) of this section, regardless of whether or not subsequently filed applications are directly mutually exclusive with the first filed application. [For example, applications A, B, and C are filed in that order. A and B are directly mutually exclusive, B and C are directly mutually exclusive. In order to be considered comparatively with B, C must be filed within the "cut-off" period established by A even though C is not directly mutually exclusive with A.] (d) Private fixed microwave applications for authorization under this Part will be entitled to be included in a random selection process or to comparative consideration with one or more conflicting applications in accordance with the provisions of 1.227(b)(4). (e) An application otherwise mutually exclusive with one of more previously filed applications, but filed after the appropriate date prescribed in paragraphs (b) or (d) of this section, will be returned without prejudice and will be eligible for refiling only after final action is taken by the Commission with respect to the previously filed application (or applications). (f) For the purposes of this section, any application (whether mutually exclusive or not) will be considered to be a newly filed application if it is amended by a major amendment (as defined by  101.29), except under any of the following circumstances: (1) The application has been designated for comparative hearing, or for comparative evaluation (pursuant to Sec. 101.51), and the Commission or the presiding officer accepts the amendment pursuant to Sec. 101.29(b); (2) The amendment resolves frequency conflicts with authorized stations or other pending applications which would otherwise require resolution by hearing, by comparative evaluation pursuant to Sec. 101.51, or by random selection pursuant to Sec. 101.49 provided that the amendment does not create new or additional frequency conflicts; (3) The amendment reflects only a change in ownership or control found by the Commission to be in the public interest, and for which a requested exemption from the "cut-off" requirements of this section is granted; (4) The amendment reflects only a change in ownership or control which results from an agreement under Sec. 101.41 whereby two or more applicants entitled to comparative consideration of their applications join in one (or more) of the existing applications and request dismissal of their other application (or applications) to avoid the delay and cost of comparative consideration; (5) The amendment corrects typographical, transcription, or similar clerical errors which are clearly demonstrated to be mistakes by reference to other parts of the application, and whose discovery does not create new or increased frequency conflicts; or (6) The amendment does not create new or increased frequency conflicts, and is demonstrably necessitated by events which the applicant could not have reasonably foreseen at the time of filing, such as, for example: (i) The loss of a transmitter or receiver site by condemnation, natural causes, or loss of lease or option; (ii) Obstruction of a proposed transmission path caused by the erection of a new building or other structure; or (iii) The discontinuance or substantial technological obsolescence of specified equipment, whenever the application has been pending before the Commission for two or more years from the date of its filing. (g) Applicants for the 932.5-935/941.5-944 MHz bands shall select a frequency pair. Applicants for these bands may select an unpaired frequency only upon a showing that spectrum efficiency will not be impaired and that unpaired spectrum is not available in other bands. During the initial filing window, frequency coordination is not required, except that an application for a frequency in the 942-944 MHz band must be coordinated to ensure that it does not affect an existing broadcast auxiliary service licensee. After the initial filing window, an applicant must submit evidence that frequency coordination has been performed with all licensees affected by the application. All frequency coordination must be performed in accordance with  101.103 of the Commission's Rules. In the event of mutually exclusive applications occurring during the initial filing window for the 932.5-935/941.5-944 MHz bands, applicants shall be given the opportunity to resolve these situations by applying for an alternative frequency pair, if one is available. To the extent that there are no other available frequencies or to the extent that mutually exclusive applications remain after this process is concluded, lotteries shall be conducted for each frequency pair among all remaining mutually exclusive applications, assuming appropriate coordination with existing broadcast auxiliary stations can be concluded, where necessary. In the event of mutually exclusive applications being received for these bands on the same day after the initial filing window has closed and a subsequent filing window opened, lotteries shall be conducted for each frequency pair among all mutually exclusive applications.  101.47 Consideration of applications. (a) Applications for an instrument of authorization will be granted if, upon examination of the application and upon consideration of such other matters as it may officially notice, the Commission finds that the grant will serve the public interest, convenience, and necessity. (b) The grant will be without a formal hearing if, upon consideration of the application, any pleadings of objections filed, or other matters which may be officially noticed, the Commission finds that: (1) The application is acceptable for filing, and is in accordance with the Commission's rules, regulations, and other requirements; (2) The application is not subject to comparative consideration (pursuant to  101.45) with another application (or applications), except where the competing applicants have chosen the comparative evaluation procedure of  101.51 and a grant is appropriate under that procedure; (3) A grant of the application would not cause harmful electrical interference to an authorized station; (4) There are no substantial and material questions of fact presented; and (5) The applicant is legally, technically, financially and otherwise qualified, and a grant of the application would serve the public interest. (c) Whenever the Commission, without a formal hearing, grants any application in part, or subject to any terms or conditions other than those normally applied to applications of the same type, it will inform the applicant of the reasons therefor, and the grant will be considered final unless the Commission revises its action (either by granting the application as originally requested, or by designating the application for a formal evidentiary hearing) in response to a petition for reconsideration that: (1) Is filed by the applicant within thirty (30) days from the date of the letter or order giving the reasons for the partial or conditioned grant; (2) Rejects the grant as made and explains the reasons why the application should be granted as originally requested; and (3) Returns the instrument of authorization. (d) The Commission will designate an application for a formal hearing, specifying with particularity the matters and things in issue, if, upon consideration of the application, any pleadings or objections filed, or other matters which may be officially noticed, the Commission determines that: (1) A substantial and material question of fact is presented; (2) The Commission is unable for any reason to make the findings specified in paragraph (a) of this section and the application is acceptable for filing, complete, and in accordance with the Commission's rules, regulations, and other requirements. (3) The application is entitled to comparative consideration (under  101.45) with another application (or applications); or (4) The application is entitled to comparative consideration (pursuant to  101.45) and the applicants have chosen the comparative evaluation procedure of  101.51 but the Commission deems such procedure to be inappropriate. (e) The Commission may grant, deny, or take other action with respect to an application designated for a formal hearing pursuant to paragraph (d) of this section or Part 1 of this chapter. (f) Whenever the public interest would be served thereby the Commission may grant one or more mutually exclusive applications expressly conditioned upon final action on the applications, and then either conduct a random section process (in specified services under this rules part), designate all of the mutually exclusive applications for a formal evidentiary hearing or (whenever so requested) follow the comparative evaluation procedures of  101.51, as appropriate, if it appears: (1) That some or all of the applications were not filed in good faith, but were filed for the purpose of delaying or hindering the grant of another application; (2) That the public interest requires the prompt establishment of radio service in a particular community or area; (3) That a delay in making a grant to any applicant until after the conclusion of a hearing or a random selection proceeding on all applications might jeopardize the rights of the United States under the provision of an international agreement to the use of the frequency in question; or (4) That a grant of one application would be in the public interest in that it appears from an examination of the remaining applications that they cannot be granted because they are in violation of provisions of the Communications Act, other statutes, or of the provisions of this chapter. (g) Reconsideration or review of any final action taken by the Commission will be in accordance with Subpart A of Part 1 of this chapter.  101.49 Grants by random selection. (a) If an application for an authorization in the Digital Electronic Message Service (DEMS) is mutually exclusive with another such application and satisfies the requirements of  101.45, the applicant may be included in the random selection process set forth in  1.821, 1.822 and 1.825 of this chapter. (b) Renewal applications will not be included in a random selection process.  101.51 Comparative evaluation of mutually exclusive applications. (a) In order to expedite action on mutually exclusive applications in services under this rules part where the random selection process does not apply, the applicants may request the Commission to consider their applications without a formal hearing in accordance with the summary procedure outlined in paragraph (b) in this section if: (1) The applications are entitled to comparative consideration pursuant to Sec. 101.45; (2) The applications have not been designated for formal evidentiary hearing; and (3) The Commission determines, initially or at any time during the procedure outlined in paragraph (b) of this section, that such procedure is appropriate, and that, from the information submitted and consideration of such other matters as may be officially noticed, there are no substantial and material questions of fact presented (other than those relating to the comparative merits of the applications) which would preclude a grant under paragraphs (a) and (b) of  101.47. (b) Provided that the conditions of paragraph (a) of this section are satisfied, applicants may request the Commission to act upon their mutually exclusive applications without a formal hearing pursuant to the summary procedure outlined below: (1) To initiate the procedure, each applicant will submit to the Commission a written statement containing: (i) A waiver of the applicant's right to a formal hearing; (ii) A request and agreement that, in order to avoid the delay and expense of a comparative formal hearing, the Commission should exercise its judgment to select from among the mutually exclusive applications that proposal (or proposals) which would best serve the public interest; and (iii) The signature of a principal (and the principal's attorney if represented). (2) After receipt of the written requests of all of the applicants the Commission (if it deems this procedure appropriate) will issue a notice designating the comparative criteria upon which the applications are to be evaluated and will request each applicant to submit, within a specified period of time, additional information concerning the applicant's proposal relative to the comparative criteria. (3) Within thirty (30) days following the due date for filing this information, the Commission will accept concise and factual argument on the competing proposals from the rival applicants, potential customers, and other knowledgeable parties in interest. (4) Within fifteen (15) days following the due date for the filing of comments, the Commission will accept concise and factual replies from the rival applicants. (5) From time to time during the course of this procedure the Commission may request additional information from the applicants and hold informal conferences at which all competing applicants will have the right to be represented. (6) Upon evaluation of the applications, the information submitted, and such other matters as may be officially noticed the Commission will issue a decision granting one (or more) of the proposals which it concludes would best serve the public interest, convenience and necessity. The decision will report briefly and concisely the reasons for the Commission's selection and will deny the other application(s). This decision will be considered final. License Transfers, Modifications, Conditions and Forfeitures  101.53 Assignment or transfer of station authorization. (a) No station license, or any rights thereunder, may be transferred, assigned, or disposed of in any manner, voluntarily or involuntarily, directly or indirectly, or by transfer of control of any corporation or any other entity holding any such license, to any person except upon application to the Commission and upon finding by the Commission that the public interest, convenience and necessity will be served thereby. (b) For purposes of this section, transfers of control requiring Commission approval must include any and all transactions that: (1) Change the party controlling the affairs of the licensee, or (2) Affect any change in a controlling interest in the ownership of the licensee, including changes in legal or equitable ownership, or (c) Requests for transfer of control or assignment authority must be submitted on the application form prescribed by  101.17 of this chapter, and must be accompanied by the applicable showings required by  101.19, 101.21, and 101.55 of this chapter. (d) The Commission must be promptly notified in writing when a licensee is voluntarily or involuntarily placed in bankruptcy or receivership and when an individual licensee, a member of a partnership which is a licensee, or a person directly or indirectly in control of a corporation which is a licensee, dies or becomes legally disabled. Within thirty days after the occurrence of such bankruptcy, receivership, death or legal disability, an application of involuntary assignment of such license, or involuntary transfer of control of such corporation, must be filed with the Commission, requesting assignment or transfer to a successor legally qualified under the laws of the place having jurisdiction over the assets involved. (e) The assignor of a station licensed under this part may retain no right of reversion or reassignment of the license and may not reserve the right to use the facilities of the station for any period whatsoever. No assignment of license will be granted or authorized if there is a contract or understanding, express or implied, pursuant to which a right of reversion or reassignment of the license or right to use the facilities are retained as partial or full consideration for the assignment or transfer. (f) No special temporary authority, or any rights thereunder, may be assigned or otherwise disposed of, directly or indirectly, voluntarily or involuntarily, without prior Commission approval.  101.55 Considerations involving transfer or assignment applications. (a) Licenses may not be assigned or transferred prior to the completion of construction of the facility. However, consent to the assignment or transfer of control of such a license may be given prior to the completion of construction where: (1) The assignment or transfer does not involve a substantial change in or ownership or control of the authorized facilities; or in (2) The assignment or transfer of control is involuntary due to the licensee's bankruptcy, death, or legal disability. (b) The Commission will review a proposed transaction to determine if the circumstances indicate "trafficking" in licenses whenever applications (except those involving pro forma assignment or transfer of control) for consent to assignment of a license, or for transfer of control of a licensee, involve facilities that were: (1) Authorized following a comparative hearing and have been operated less than one year, or; (2) Involve facilities that have not been constructed, or; (3) Involve facilities that were authorized following a random selection proceeding in which the successful applicant received preference and that have been operated for less than one year. At its discretion, the Commission may require the submission of an affirmative, factual showing (supported by affidavits of a person or persons with personal knowledge thereof) to demonstrate that the proposed assignor or transferor has not acquired an authorization or operated a station for the principal purpose of profitable sale rather than public service. This showing may include, for example, a demonstration that the proposed assignment or transfer is due to changed circumstances (described in detail) affecting the licensee subsequent to the acquisition of the license, or that the proposed transfer of radio facilities is incidental to a sale of other facilities or merger of interests. (c) If a proposed transfer of radio facilities is incidental to a sale of other facilities or merger of interests, any showing requested under paragraph (a) of this section must include an additional exhibit that: (1) Discloses complete details as to the sale of facilities or merger of interests; (2) Segregates clearly by an itemized accounting, the amount of consideration involved in the sale of facilities or merger of interests; and (3) Demonstrates that the amount of consideration assignable to the facilities or business interests involved represents their fair market value at the time of the transaction. (d) For the purposes of this section, the one year period is calculated using the following dates (as appropriate): (1) The initial date of grant of the license, excluding subsequent modifications; (2) The date of consummation of an assignment or transfer, if the station is acquired as the result of an assignment of license, or transfer of control of corporate licensee; or (3) The median date of the applicable commencement dates (determined pursuant to paragraphs (d) (1) and (2) of this section) if the transaction involves a system (such as a Point-to-Point Microwave System) of two or more stations. (The median date is that date so selected such that fifty percent of the commencement dates of the total number of stations, when arranged in chronological order, lie below it and fifty percent lie above it. When the number of stations is an even number, the median date will be a value half way between the two dates closest to the theoretical median).  101.57 Modification of station license. (a) Except as provided in  101.59, no modification of a license issued pursuant to this part (or the facilities described thereunder) may be made except upon application to the Commission. (b) No application for modification to extend a license construction period will be granted for delays caused by lack of financing or for lack of site availability. Applications for time extensions for other reasons must include a verified statement from the applicant showing that the licensee has made diligent efforts to construct the facilities and: (1) That additional time is required due to circumstances beyond the applicant's control, in which case the applicant must describe such circumstances and must set forth with specificity and justify the precise extension period requested; or (2) That there are unique and overriding public interest concerns that justify such an extension, in which case the applicant must identify such interests and must set forth and justify a precise extension period. (c) Notwithstanding the provisions of paragraph (b), when a station license has been assigned or transferred pursuant to  101.53, any extension of time will be limited so that the time left to construct after Commission grant of the transfer or assignment will be no more than the time remaining for construction at the date of the filing of the application for transfer or assignment. (d) Modification of license is required for the following changes in authorized stations: (1) Any change in frequencies used; (2) Any change in antenna azimuth; (3) Any change in antenna beamwidth; (4) Any change in antenna or passive repeater location greater than 1 second or which involves a requirement for special aeronautical study; (5) Any change in antenna polarization; (6) Any change in antenna height; (7) Any change in the size of passive reflectors or repeaters associated with the facilities of an authorized station; (8) Any increase in emission bandwidth beyond that authorized; (9) Any change in the type of emission; (10) Any change in authorized effective radiated power in excess of 3 dB (a 2-to-1 ratio); (11) Substitution of equipment having different frequency tolerance. (e) When the name of the licensee is changed (without changes in the ownership, control, or corporate structure), or when the mailing address is changed (without changing the authorized location of the fixed station) a formal application for modification of license is not required. However, the licensee must notify the Commission within thirty days of the effective date of these changes. The notice, which may be in letter form, must contain the name and address of the licensee as they appear in the Commission's records, the new name or address, the call signs and classes of all radio stations authorized to the licensee under this part and the radio service in which each station is authorized. The notice must be sent to the Federal Communications Commission, Gettysburg, PA 17325 and a copy must be maintained with the license of each station until a new license is issued.  101.59 Processing of applications for facility minor modifications. (a) Unless an applicant is notified to the contrary by the Commission, as of the twenty-first day following the date of public notice, any application that meets the requirements of paragraph (b) of this section and proposes only the change specified in paragraph (c) of this section will be deemed to have been authorized by the Commission. (b) An application may be considered under the procedures of this section only if: (1) It is in the Point-to-Point Microwave Radio, Local Television Transmission, or Digital Electronic Message Service; (2) The cumulative effect of all such applications made within any 60 days period does not exceed the appropriate values prescribed by paragraph (c) of this section; (3) The facilities to be modified are not located within 56.3 kilometers (35 miles) of the Canadian or Mexican border; (4) It is acceptable for filing, is consistent with all of the Commission's rules, and does not involve a waiver request; (5) It specifically requests consideration pursuant to this section; and (6) Frequency coordination procedures, as necessary, are complied with in accordance with  101.103(d) or, in the Digital Electronic Message Services, a copy of the application has been served on those who also were served under  101.509. (c) The modifications that may be authorized under the procedures of this section are: (1) Changes in a transmitter and existing transmitter operating characteristics, or protective configuration of transmitter, provided that: (i) In all radio services other than Digital Electronic Message Service, any increase in transmitter output power is less than three dB over the previously authorized output power; and in Digital Electronic Message Service, any increase in transmitter output power is one and one-half dB or less over the previously authorized output power; (ii) The necessary bandwidth is not increased beyond the previously authorized bandwidth; (2) Changes in the center line height of an antenna, provided that: (i) In all radio services except the Digital Electronic Message Service, any increase in antenna height is less than 6.1 meters (20 feet) above the previously authorized height; (ii) In Digital Electronic Message Service, any increase in antenna height is less than 3.0 meters (10 feet) above the previously authorized height; and (iii) The overall height of the antenna structure is not increased as a result of the antenna extending above the height of the previously authorized structure, except when the new height of the antenna structure is 6.1 meters (20 feet) or less (above ground or man-made structure, as appropriate) after the change is made. (3) Change in the geographical coordinates of a transmit station, receive station or passive facility by five (5) seconds or less of latitude, longitude or both, provided that when notice to the FAA of proposed construction is required by Part 17 of the rules for antenna structure at the previously authorized coordinates (or will be required at the new location) the applicant must comply with the provisions of  101.21(a). (d) Upon grant of an application under the procedure of this section and at such time that construction begins, the applicant must keep a complete copy of the application (including the filing date) with the station license if construction begins prior to receipt of the authorization.  101.61 Certain modifications not requiring prior authorization. (a) Equipment in an authorized radio station may be replaced without prior authorization or notification if the replacement equipment is equivalent to the replaced equipment. (b) Licensees of fixed stations in the Point-to-Point Microwave Radio, Local Television Transmission, or Digital Electronic Message, may make the facility changes listed in paragraph (c) of this section without obtaining prior Commission authorization, if: (1) Frequency coordination procedures, as necessary, are complied with in accordance with  101.103(d) or, in the Digital Electronic Message Services, a copy of the notification described in (b)(3) is served on those who were served under  101.509, and (2) The cumulative effect of all facility changes made within any 60 day period does not exceed the appropriate values prescribed by paragraph (c) of this section, and (3) The Commission is notified of changes made to facilities by the submission of a completed FCC Form 494 within thirty days after the changes are made. (c) Modifications that may be made without prior authorization under paragraph (b) of this section are: (1) Change or modification of a transmitter, when: (i) The replacement or modified transmitter is type-accepted (or type-notified) for use under this Part and is installed without modification from the type-accepted (or type notified) configuration; (ii) The type of modulation is not changed; (iii) The frequency stability is equal to or better than the previously authorized frequency stability; and (iv) The necessary bandwidth and the output power do not exceed the previously authorized values. (2) Addition or deletion of a transmitter for protection without changing the authorized power output (e.g. hot standby transmitters); (3) Change to an antenna (other than any change involving a periscope antenna system), when: (i) For the Point-to-Point Microwave Radio and Local Television Transmission Services, the new antenna conforms to the requirements of  101.115 and has essentially the same or better radiation characteristics than the previously authorized antenna; (ii) For the Digital Electronic Message Service, the new antenna conforms with  101.517 and the gain of the new antenna does not exceed that of the previously authorized antenna by more than one dB in any direction. (4) Any technical changes that would decrease the effective radiated power. (5) Change to the height of an antenna, when: (i) The new height (measured at the center-of-radiation) is within +/- 1.5 meters (5 feet) of the previously authorized height; and (ii) The overall height of the antenna structure is not increased as a result of the antenna extending above the height of the previously authorized structure, except when the new height of the antenna structure is 6.1 meters (20 feet) or less (above ground or man-made structure, as appropriate) after the change is made. (6) Decreases in the overall height of an antenna structure, provided that, when notice to the FAA of proposed construction was required by Part 17 of the Rules for the antenna structure at the previously authorized height, the applicant must comply with the provisions of  101.21(a). (7) Changes in the azimuth of the center of the main lobe of radiation of a point-to-point station's antenna by a maximum of one degree. (8) Changes to the transmission line and other devices between the transmitter and the antenna when the effective radiated power of the station is not increased by more than one dB. (d) Licensees may notify the Commission of permissible changes or correct erroneous information on a license not involving a major change (i.e., a change that would be classified as a major amendment as defined by  101.29) without obtaining prior Commission approval by filing FCC Form 494.  101.63 Period of construction; certification of completion of construction. (a) Except as provided in paragraphs (b) and (f) of this section, each station authorized under this part must be in operation within 12 months from the initial date of grant. Modification of an operational station must be completed within 12 months of the date of grant of the applicable modification request. (b) Each station licensed on point-to-multipoint frequencies in the 10.6 GHz and 18 GHz bands must be in operation within 18 months of the initial date of grant. Modification of an operational station must be completed within 18 months of the initial date of grant of the applicable modification request. (c) Failure to timely begin operation means the authorization cancels automatically and must be returned to the Commission. Neither the capability for transmission nor the transmission of color bars or similar test signals constitutes operation. For purposes of this rule, the transmission of operational traffic, not test or maintenance signals, is necessary and sufficient to constitute operation. (d) The frequencies associated with all point-to-multipoint authorizations which have cancelled automatically or otherwise been recovered by the Commission will again be made available for reassignment on a date and under terms set forth by Public Notice. (e) Requests for extension of time to be in operation may be granted upon a showing of good cause, setting forth in detail the applicant's reasons for failure to have the facility operating in the prescribed period. Such requests must be submitted no later than 30 days prior to the end of the prescribed period to the Federal Communications Commission, Gettysburg, PA 17325-7245. (f) Construction of Common Carrier stations may not commence until the grant of a license, and must be completed by the date specified in the license as the termination date of the construction period. Each licensee must file with the Commission a certification of completion of construction using FCC Form 494A, certifying that the facilities as authorized have been completed and that the station is now operational and ready to provide service to the public, and will remain operational during the license period, unless the license is submitted for cancellation.  101.65 Forfeiture and termination of station authorization. (a) A common carrier license will be automatically forfeited in whole or in part without further notice to the licensee upon: (1) The expiration of the construction period specified therein, or after such additional time as may be authorized by the Commission, unless within 5 days after construction period date a certification of completion of construction has been filed with the Commission pursuant to  101.63; or (2) The expiration of the license period specified therein, unless prior thereto an application for renewal of such license has been filed with the Commission; or (3) The voluntary removal or alteration of the facilities, so as to render the station not operational for a period of 30 days or more. (b) A license forfeited in whole or in part under the provisions of paragraph (a)(1) or (a)(2) may be reinstated if the Commission, in its discretion, determines that reinstatement would best serve the public interest, convenience and necessity. Petitions for reinstatement filed pursuant to this subsection will be considered only if: (1) The petition is filed within 30 days of the expiration date set forth in paragraph (a)(1) or (a)(2) of this section, whichever is applicable; (2) The petition explains the failure to timely file such notification or application as would have prevented automatic forfeiture; and (3) The petition sets forth with specificity the procedures which have been established to insure timely filings in the future. (c) A special temporary authorization will automatically terminate upon the expiration date specified therein, or upon failure to comply with any special terms or conditions set forth therein. Operation may be extended beyond such termination date only after application and upon specific authorization by the Commission. (d) If a station licensed under this part discontinues operation on a permanent basis, the licensee must forward the station license to the Federal Communications Commission, Gettysburg, Pennsylvania 17325, for cancellation. For purposes of this section, any station which has not operated for one year or more is considered to have been permanently discontinued. See Section 101.305 for additional rules regarding temporary and permanent discontinuation of service.  101.67 License period. (a) Except as provided in paragraph (e) of this Section, licenses for stations authorized under this Part will be issued for a period not to exceed 10 years from date of grant. (b)The expiration date of developmental licenses will be one year from the date of the grant thereof. When a license is granted subsequent to the last renewal date of the class of license involved, the license will be issued only for the unexpired period of the current license term of such class. (c) The Commission reserves the right to grant or renew station licenses in these services for a shorter period of time than that generally prescribed for such stations if, in its judgment, public interest, convenience, or necessity would be served by such action. (d) Upon the expiration or termination of any station license, any related construction permit, which bears a later expiration date, will be automatically terminated concurrently with the related station license, unless it has been determined by the Commission that the public interest, convenience or necessity would be served by continuing in effect said construction permit. (e) Licenses for Local Television Transmission Service stations that are assigned frequencies allocated to the broadcast services shall terminate simultaneously with the expiration of the authorization for the broadcast station to which such service is rendered.  101.69 Transition of the 2.11-2.13, and 2.16-2.18 GHz bands from Common Carrier Fixed Microwave Services and the 1.85-1.99, 2.13-2.15, and 2.18-2.20 GHz bands from Private Operational Fixed Microwave Service to emerging technologies. (a) Licensees proposing to implement services using emerging technologies (ET Licensees) may negotiate with Common Carrier and Private Operational Fixed Microwave Service licensees (Existing Licensees) in these bands for the purpose of agreeing to terms under which the Existing Licensees would relocate their operations to other fixed microwave bands or to other media, or alternatively, would accept a sharing arrangement with the ET Licensee that may result in an otherwise impermissible level of interference to the existing licensee's operations. ET Licensees may also negotiate agreements for relocation of the Existing Licensees' facilities within the 2 GHz band in which all interested parties agree to the relocation of the Existing Licensee's facilities elsewhere within these bands. "All interested parties" includes the incumbent licensee, the emerging technology provider or representative requesting and paying for the relocation, and any emerging technology licensee of the spectrum to which the incumbent's facilities are to be relocated. (b) Common Carrier and Private Operational Fixed Microwave licensees, with the exception of public safety facilities defined in paragraph (f) of this section, in bands allocated for licensed emerging technology services will maintain primary status in these bands until two years after the Commission commences acceptance of applications for an emerging technology services (two-year voluntary negotiation period), and until one year after an emerging technology service licensee initiates negotiations for relocation of the fixed microwave licensee's operations (one-year mandatory negotiation period) or, in bands allocated for unlicensed emerging technology services, until one year after an emerging technology unlicensed equipment supplier or representative initiates negotiations for relocation of the fixed microwave licensee's operations (one-year mandatory negotiation period). When it is necessary for an emerging technology provider or representative of unlicensed device manufacturers to negotiate with a fixed microwave licensee with operations in spectrum adjacent to that of the emerging technology provider, the transition schedule of the entity requesting the move will apply. Public safety facilities defined in paragraph (f) of this section will maintain primary status in these bands until four years after the Commission commences acceptance of applications for an emerging technology service (four-year voluntary negotiation period), and until one year after an emerging technology service licensee or an emerging technology unlicensed equipment supplier or representative initiates negotiations for relocation of the fixed microwave licensee's operations (one-year mandatory negotiation period). (c) The Commission will amend the operation license of the fixed microwave operator to secondary status only if the following requirements are met: (1) The service applicant, provider, licensee, or representative using an emerging technology guarantees payment of all relocation costs, including all engineering, equipment, site and FCC fees, as well as any reasonable, additional costs that the relocated fixed microwave licensee might incur as a result of operation in another fixed microwave band or migration to another medium; (2) The emerging technology service entity completes all activities necessary for implementing the replacement facilities, including engineering and cost analysis of the relocation procedure and, if radio facilities are used, identifying and obtaining, on the incumbents' behalf, new microwave frequencies and frequency coordination; and (3) The emerging technology service entity builds the replacement system and tests it for comparability with the existing 2 GHz system. (d) The 2 GHz microwave licensee is not required to relocate until the alternative facilities are available to it for a reasonable time to make adjustments, determine comparability, and ensure a seamless handoff. (e) If within one year after the relocation to new facilities the 2 GHz microwave licensee demonstrates that the new facilities are not comparable to the former facilities, the emerging technology service entity must remedy the defects or pay to relocate the microwave licensee back to its former or equivalent 2 GHz frequencies. (f) Public safety facilities subject to the four-year voluntary and one-year mandatory negotiation periods, are those that the majority of communications carried are used for police, fire, or emergency medical services operations involving safety of life and property. The facilities within this exception are those facilities currently licensed on a primary basis pursuant to the eligibility requirements of  90.19, Police Radio Service;  90.21, Fire Radio Service;  90.27 Emergency Medical Radio Service; and Subpart C of Part 90, Special Emergency Radio Services. Licensees of other Part 101 facilities licensed on a primary basis under the eligibility requirements of Part 90, Subparts B and C, are permitted to request similar treatment upon demonstrating that the majority of the communications carried on those facilities are used for operations involving safety of life and property.

After these applications have been processed, the Commission will announce by public notice a filing date for remaining frequencies. From this filing date forward, applications will be processed on a daily first-come, first-served basis.  101.103 Frequency coordination procedures. (a) Assignment of frequencies will be made only in such a manner as to facilitate the rendition of communication service on an interference-free basis in each service area. Unless otherwise indicated, each frequency available for use by stations in these services will be assigned exclusively to a single applicant in any service area. All applicants for, and licensees of, stations in these services must cooperate in the selection and use of the frequencies assigned in order to minimize interference and thereby obtain the most effective use of the authorized facilities. In the event harmful interference occurs or appears likely to occur between two or more radio systems and such interference cannot be resolved between the licensees thereof, the Commission may specify a time sharing arrangement for the stations involved or may, after notice and opportunity for hearing, require the licensees to make such changes in operating techniques or equipment as it may deem necessary to avoid such interference. (b) The provisions of this section do not apply to operations in the band 31.0 to 31.3 GHz. Operations in this band are unprotected and subject to harmful interference from other licensed operations in this band. (c) Frequency diversity transmission will not be authorized in these services in the absence of a factual showing that the required communications cannot practically be achieved by other means. Where frequency diversity is deemed to be justified on a protection channel basis, it will be limited to one protection channel for the bands 3,700-4,200, 5925-6425, and 6525-6875 MHz, and a ratio of one protection channel for three working channels for the bands 10,550-10,680 and 10,700-11,700 MHz. In the bands 3,700-4,200, 5,925-6,425, and 6525-6875 MHz, no frequency diversity protection channel will be authorized unless there is a minimum of three working channels, except that where a substantial showing is made that a total of three working channels will be required within three years, a protection channel may be authorized simultaneously with the first working channel. A protection channel authorized under such exception will be subject to termination if applications for the third working channel are not filed within three years of the grant date of the applications for the first working channel. Where equipment employing digital modulation techniques with cross-polarized operation on the same frequency is used, the protection channel authorized under the above conditions may be considered to consist of both polarizations of the protection frequency where such is shown to be necessary. (d) Frequency coordination. When required, the following frequency usage coordination procedures will apply. (1) General requirements. Proposed frequency usage must be prior coordinated with existing users in the area, and other applicants with previously filed applications, whose facilities could affect or be affected by the new proposal in terms of frequency interference on active channels, applied-for channels, or channels coordinated for future growth. Coordination must be completed prior to filing an application for regular authorization, or an amendment to a pending application, or a modification to a license. In coordinating frequency usage with stations in the fixed satellite service, applicants must also comply with the requirements of Sec. 101.713(c) and (d). In engineering a system or modification thereto, the applicant must, by appropriate studies and analyses, select sites, transmitters, antennas and frequencies that will avoid interference in excess of permissible levels to other users. All applicants and licensees must cooperate fully and make reasonable efforts to resolve technical problems and conflicts that may inhibit the most effective and efficient use of the radio spectrum; however, the party being coordinated with is not obligated to suggest changes or re-engineer a proposal in cases involving conflicts. Applicants should make every reasonable effort to avoid blocking the growth of systems as prior coordinated. The applicant must identify in the application all entities with which the technical proposal was coordinated. In the event that technical problems are not resolved, an explanation must be submitted with the application. Where technical problems are resolved by an agreement or operating arrangement between the parties that would require special procedures be taken to reduce the likelihood of interference in excess of permissible levels (such as the use of artificial site shielding)or would result in a reduction of quality or capacity of either system, the details thereof may be contained in the application. (2) Coordination procedure guidelines are as follows: (i) Coordination involves two separate elements: notification and response. Both or either may be oral or in written form. To be acceptable for filing, all applications and major technical amendments must certify that coordination, including response, has been completed. The names of the users with coordinated proposals, applicants, permittees, and licensees with which coordination was accomplished must be specified. (ii) Notification must include relevant technical details of the proposal. At minimum, this should include, as applicable, the following: Applicant's name. Transmitting station name. Transmitting station coordinates. Frequencies and polarizations to be added or changed. Transmitting equipment type, its stability, actual output power, emission designator, and type of modulation (loading). Transmitting antenna type and model and, if required, a radiation pattern provided or certified by the manufacturer. Transmitting antenna center line height above ground level and ground elevation above mean sea level. Receiving station name. Receiving station coordinates. Receiving antenna type, model, gain, and, if required, a radiation pattern provided by the manufacturer. Receiving antenna center line height above ground level and ground elevation above mean sea level. Forward and reverse path azimuth and distance. (iii) For transmitters employing digital modulation techniques, the notification should clearly identify the type of modulation. Upon request, additional details of the operating characteristics of the equipment must also be furnished. (iv) Response to notification should be made as quickly as possible, even if no technical problems are anticipated. Any response to notification indicating potential interference must specify the technical details and must be provided to the applicant, in writing, within the 30-day notification period. Every reasonable effort should be made by all applicants, permittees and licensees to eliminate all problems and conflicts. If no response to notification is received within 30 days, the applicant will be deemed to have made reasonable efforts to coordinate and may file its application without a response. (v) The 30-day notification period is calculated from the date of receipt by the applicant, permittee, or licensee being notified. If notification is by mail, this date may be ascertained by: (A) The return receipt on certified mail, (B) The enclosure of a card to be dated and returned by the recipient, or (C) A conservative estimate of the time required for the mail to reach its destination. In the latter case, the estimated date when the 30-day period would expire should be stated in the notification. (vi) An expedited prior coordination period (less than 30 days) may be requested when deemed necessary by a notifying carrier. The coordination notice should be identified as "expedited" and the requested response date should be clearly indicated. However, circumstances preventing a timely response from the receiving carrier should be accommodated accordingly. It is the responsibility of the notifying carrier to receive written concurrence (or verbal, with written to follow) from affected parties or their coordination representatives. (vii) All technical problems that come to light during coordination must be resolved unless a statement is included with the application to the effect that the applicant is unable or unwilling to resolve the conflict and briefly the reason therefor. (viii) Where a number of technical changes become necessary for a system during the course of coordination, an attempt should be made to minimize the number of separate notifications for these changes. Where the changes are incorporated into a completely revised notice, the items that were changed from the previous notice should be identified. When changes are not numerous or complex, the carrier receiving the changed notification should make an effort to respond in less than 30 days. When the notifying carrier believes a shorter response time is reasonable and appropriate, it may be helpful for that carrier to so indicate in the notice and perhaps suggest a response date. (ix) If, after coordination is successfully completed, it is determined that a subsequent change could have no impact on some carriers receiving the original notification, these carriers must be notified of the change and of the coordinator's opinion that no response is required. (x) Applicants, permittees and licensees should supply to all other applicants, permittees and licensees within their areas of operations, the name, address and telephone number of their coordination representatives. Upon request from coordinating applicants, permittees and licensees, data and information concerning existing or proposed facilities and future growth plans in the area of interest should be furnished unless such request is unreasonable or would impose a significant burden in compilation. (xi) Carriers should keep other carriers with whom they are coordinating advised of changes in plans for facilities previously coordinated. If applications have not been filed 6 months after coordination was initiated, carriers may assume that such frequency use is no longer desired unless a second notification has been received within 10 days of the end of the 6 month period. Renewal notifications are to be sent to all originally notified parties, even if coordination has not been successfully completed with those parties. (xii) Any frequency reserved by a licensee for future use in the bands subject to this Part must, upon a showing by another licensee that it requires an additional frequency and cannot coordinate one that is not reserved for future use, file for the frequency within six (6) months after receiving such a showing or release the frequency for use by the requesting licensee. (e) Where frequency conflicts arise between co-pending applications in the Point-to-Point Microwave Radio and Local Television Transmission Services, it is the obligation of the later filing applicant to amend his application to remove the conflict, unless it can make a showing that the conflict cannot be reasonably eliminated. Where a frequency conflict is not resolved and no showing is submitted as to why the conflict cannot be resolved, the Commission may grant the first filed application and dismiss the later filed application(s) after giving the later filing applicant(s) 30 days to respond to the proposed action. (f) When the proposed facilities are to be operated in the band 12,500-12,700 MHz, applications must also follow the procedures in  101.713 of this Part and the technical standards and requirements of Part 25 of this Chapter as regards licensees in the Communication-Satellite Service.  101.105 Interference protection criteria. (a) The interference protection criteria for fixed stations subject to this Part are as follows: (1) To long-haul analog systems, employing frequency modulated radio and frequency division multiplexing to provide multiple voice channels, the allowable interference level per exposure: (i) Due to co-channel sideband-to-sideband interference must not exceed 5 pwpO (Picowatts of absolute noise power psophometrically weighted (pwpO), appearing in an equivalent voice band channel of 300-3400 Hz). (ii) Due to co-channel carrier-beat interference must not exceed 50 pwpO. (2) To short-haul analog systems employing frequency modulated radio and frequency division multiplexing to provide multiple voice channels, the allowable interference level per exposure: (i) Due to co-channel sideband-to-sideband interference must not exceed 25 pwpO except in the 952-960 MHz band interference into single link fixed relay and control stations must not exceed 250 pwpO per exposure. (ii) Due to co-channel carrier-beat interference must not exceed 50 pwpO except in the 952-960 MHz band interference into single link fixed relay and control stations must not exceed 1000 pwpO per exposure. (3) FM-TV. In analog systems employing frequency modulated radio that is modulated by a standard, television (visual) signal, the allowable interference level per exposure may not exceed the levels which would apply to a long-haul or short-haul FM-FDM systems, as outlined in paragraphs (b)(1) and (2) of this section, having a 600-1200 voice channel capacity. (b) In addition to the requirements of paragraph (a) of this Section the adjacent channel interference protection criteria to be afforded, regardless of system length, or type of modulation, multiplexing, or frequency band, must be such that the interfering signal does not produce more than 1.0 dB degradation of the practical threshold of the protected receiver. (c) Applying the Criteria. (1) Guidelines for applying the interference protection criteria for fixed stations subject to this Part are specified in TIA Telecommunications Systems Bulletin TSB 10, "Interference Criteria for Microwave Systems" (TSB 10). Other procedures that follow generally acceptable good engineering practices are also acceptable to the Commission. (2) If TSB 10 guidelines cannot be used, the following interference protection criteria may be used by calculating the ratio in dB between the desired (carrier signal) and the undesired (interfering) signal (C/I ratio) appearing at the input to the receiver under investigation (victim receiver): (i) Except as provided in  101.605 of this Part, where the applicants proposed facilities are of a type not included in paragraphs (a) and (b) of this section or where the development of the carrier-to- interference (C/I) ratio is not covered by generally acceptable procedures, or where the applicant does not wish to develop the carrier-to-interference ratio, the applicant must, in the absence of criteria or a developed C/I ration, employ the following C/I protection ratios: Co-channel interference: both sideband and carrier-beat, applicable to all bands; the existing or previously authorized system must be afforded a carrier to interfering signal protection ratio of at least 90 dB except in the 952-960 MHz band where it must be 75 dB. Adjacent channel interference: applicable to all bands; the existing or previously authorized system must be afforded a carrier to interfering signal protection ratio of at least 56 dB. (3) Applicants for frequencies listed in Sec. 101.605(a)(1) must make the following showings that protection criteria have been met over the entire service area of existing systems. Such showings may be made by the applicant or may be satisfied by a statement from a Frequency Advisory Committee. For frequencies available to more than one service, the Frequency Advisory Committee must affirmatively show that coordination with similar Committees for the other services has been accomplished. (i) For multiple address stations in the 928-929/952-960 MHz bands, a statement that the proposed system complies with the following co-channel separations from all existing stations and pending applications: Fixed-to-fixed 145 km (90 miles) Fixed-to-mobile 113 km (70 miles) Mobile-to-mobile 81 km (50 miles) Multiple address systems employing only remote stations will be treated as mobile for the purposes of determining the appropriate separation. For mobile operation, the mileage is measured from the reference point specified on the license application. (ii) For multiple address stations in the 932-932.5/941-941.5 MHz bands, a statement that the proposed system complies with the following co-channel separation from all existing stations and pending applications: Fixed-to-fixed 113 Km (70 miles) (iii) In cases where the geographic separation standard in paragraphs (c)(4)(i) and (c)(4)(ii) of this section are not followed, an engineering analysis will be submitted to show the coordination of the proposed assignment with existing systems located closer than those standards. The engineering analyses will include: (A) Specification of the interference criteria and system parameters used in the interference study. (B) Nominal service areas of each system included in the interference analysis. (C) Modified service areas resulting from the proposed system. The propagation models used to establish the service boundary limits must be specified and any special terrain features considered in computing the interference impact should be described. (D) A statement that all parties affected have agreed to the engineering analysis and will accept the calculated levels of interference. (5) Multiple address frequencies in the 956 MHz band may be assigned for use by mobile master stations on a primary basis. Multiple address frequencies in the 952 MHz band may be assigned for use by mobile master stations on a case-by-case basis. Mobile operation in the 952 MHz band will be on a secondary basis to fixed operations. (6) Each application for new or modified nodal station on channels numbered 4A, 4B, 7, 9, and 19/20 in the 10.6 GHz band and all point-to-multipoint channels in the 18 GHz band must demonstrate that all existing co-channel stations are at least 56 kilometers from the proposed nodal station site. Applicants for these channels must certify that all licensees and applicants for stations on the adjacent channels within 56 kilometers of the proposed nodal station have been notified of the proposed station and do not object. Alternatively, or if one of the affected adjacent channel interests does object, the applicant may show that all affected adjacent channel parties are provided a C/I protection ratio of 0 dB. An applicants proposing to operate at an AAT greater than 91 meters must reduce its EIRP in accordance with the following table; however, in no case may EIRP exceed 70 dBm on the 10.6 GHz channels. AAT EIRP (meters) dBm Above 300 +38 251 to 300 41 201 to 250 43 151 to 200 49 101 to 150 55 100 and below 85 (7) Each application for new or modified nodal station on channels numbered 21, 22, 23, and 24 in the 10.6 GHz band must include an analysis of the potential for harmful interference to all other licensed and previously applied for co-channel and adjacent channel station located within 80 kilometers of the location of the proposed station. The criteria contained in  101.103(d)(3) must be used in this analysis. Applicants must certify that copies of this analysis have been served on all parties which might reasonably be expected to receive interference above the levels set out in  101.103(d)(3) within 5 days of the date the subject application is filed with the Commission. (d) An applicant filing for a modification of an existing station under the provisions of  101.31 need not perform the interference protection analyses required by this section if the only modifications made to the station are one or more of the following: (1) Substitution of transmitting equipment having equal or tighter frequency tolerance. (2) Any decrease in antenna primary lobe beamwidth which is accompanied by a corresponding decrease in antenna input power so as to not increase the effective radiated power in excess of 3dB (a 2 to 1 ratio). (3) Any decrease in antenna height or transmitter output power. (e) Effective August 1, 1985, when a fixed station that conforms to the technical standards of this subpart (or, in the case of the 12,200-12,700 MHz band, a direct broadcast satellite station) receives or will receive interference in excess of the levels specified in this section as a result of an existing licensee's use of non-conforming equipment authorized between July 20, 1961 and July 1, 1976, and the interference would not result if the interfering station's equipment complied with the current technical standards, the licensee of the non-conforming station must take whatever steps are necessary to correct the situation up to the point of installing equipment which fully conforms to the technical standards of this subpart. In such cases, if the engineering analysis demonstrates that (1) the conforming station would receive interference from a non-conforming station in excess of the levels specified in this section and (2) the interference would be eliminated if the non-conforming equipment were replaced with equipment which complies with the standards of this subpart, the licensee (or prospective licensee) of the station which would receive interference must provide written notice of the potential interference to both the non-conforming licensee and the Commission's office in Gettysburg, PA. The non-conforming licensee must make all required equipment changes within 180 days from the date of official Commission notice informing the licensee that it must upgrade its equipment, unless an alternative solution has been agreed to by all parties involved in the interference situation. If a non-conforming licensee fails to make all required changes within the specified period of time, the Commission may require the licensee to suspend operation until the changes are completed.  101.107 Frequency tolerance. (a) The carrier frequency of each transmitter authorized in these services must be maintained within the following percentage of the reference frequency except as otherwise provided in paragraph (b) of this section or in the applicable subpart of this part (unless otherwise specified in the instrument of station authorization the reference frequency will be deemed to be the assigned frequency): Frequency tolerance (percent) AllMobile Mobile Frequency fixedstations stations (MHz)and base over 3 3 watts stations watts oe less 928 to 929 /2//5/ 0.0005 932 to 932.5 /2/ 0.00015 932.5 to 935 /2/ 0.00025 941 to 941.5 0.00015 941.5 to 944 0.00025 952 to 960 /7/ 944 to 1,000 0.0005 0.0005 0.0005 1,850 to 1,990 0.002 2,110 to 2,200 0.001 2,200 to 12,200 /1/ 0.005 0.005 0.005 2,450 to 2,500 0.001 6,425 to 6,875 0.005 10,550 to 10,680 0.0003 12,200 to 13,150 /6/ 0.005 12,200 to 17,700 0.030.03 0.03 17,700 to 18,820/4//5/ 0.003 18,820 to 18,920 /4//5/ 0.001 18,920 to 19,700 /4//5/ 0.003 19,700 to 40,000 /6/ 0.030.03 0.03 /1/ Applicable only to common carrier LTTS stations. Beginning Aug. 9, 1975, this tolerance will govern the marketing of LTTS equipment and the issuance of all such authorizations for new radio equipment. Until that date new equipment may be authorized with a frequency tolerance of .03 percent in the frequency range 2,200 to 10,500 MHz and .05 percent in the range 10,500 MHz to 12,200 MHz, and equipment so authorized may continue to be used for its life provided that it does not cause interference to the operation of any other licensee. /2/ Equipment authorized to be operated on frequencies between 890 and 940 MHz as of Oct. 15, 1956, must maintain a frequency tolerance within 0.03 percent subject to the condition that no harmful interference is caused to any other radio station. /3/ See Subpart G for the stability requirements for transmitters used in the Digital Electronic Message Service. /4/ Existing type accepted equipment with a frequency tolerance of +/-0.03% may be marketed until December 1, 1988. Equipment installed and operated prior to December 1, 1988 may continue to operate after that date with a minimum frequency tolerance of +/-0.03%. However, the replacement of equipment requires that the +/-0.003% tolerance be met. /5/ For remote stations with 12.5 kHz bandwidth, the tolerance is ñ 0.00015%. /6/ Applicable to private operational fixed only. For exceptions see  101.605. /7/ For private operational fixed point-to-point systems, with a channel greater than or equal to 50 kHz bandwidth, ñ 0.0005%; for multiple address master stations, regardless of bandwidth, ñ0.00015%; for multiple address remote stations with 12.5 kHz bandwidths, ñ 0.00015%; for multiple address remote stations with channels greater than 12.5 kHz bandwidth, ñ 0.0005%. (b) Heterodyne microwave radio systems may be authorized a somewhat less restrictive frequency tolerance (up to .01 percent) to compensate for frequency shift caused by numerous repeaters between base band signal insertion. Where such relaxation is sought, applicant must provide all calculations and indicate the desired tolerance over each path. In such instances the radio transmitters used must individually be capable of complying with the tolerance specified in paragraph (a) of this section. (c) As an additional requirement in any band where the Commission makes assignments according to a specified channel plan, provisions must be made to prevent the emission included within the occupied bandwidth from radiating outside the assigned channel at a level greater than that specified in  101.111.  101.109 Bandwidth. (a) Each authorization issued pursuant to these rules will show, as the emission designator, a symbol representing the class of emission which must be prefixed by a number specifying the necessary bandwidth. This figure does not necessarily indicate the bandwidth actually occupied by the emission at any instant. In those cases where Part 2 of this chapter does not provide a formula for the computation of the necessary bandwidth, the occupied bandwidth may be used in the emission designator. (b) Stations in this service will be authorized any type of emission, method of modulation, and transmission characteristic, consistent with efficient use of the spectrum and good engineering practice, except that Type B, damped-wave emission will not be authorized.  101.111 Emission limitations. (a) The mean power of emissions must be attenuated below the mean output power of the transmitter in accordance with the following schedule: (1) When using transmissions other than those employing digital modulation techniques: (i) On any frequency removed from the assigned frequency by more than 50 percent up to and including 100 percent of the authorized bandwidth: At least 25 decibels; (ii) On any frequency removed from the assigned frequency by more than 100 percent up to and including 250 percent of the authorized bandwidth: At least 35 decibels; (iii) On any frequency removed from the assigned frequency by more than 250 percent of the authorized bandwidth: At least 43+10 Log10 (mean output power in watts) decibels, or 80 decibels, whichever is the lesser attenuation.

N=Number of active subchannels of the given polarization within the DEMS channel. (ii) In any 4 kHz band within the authorized DEMS band the center frequency of which is removed from the center frequency of the DEMS channel by more that the sum of 50% of the DEMS channel bandwidth plus 1.125 times the subchannel bandwidth: As specified by the following equation but in no event less than 80 decibels.

A=80+10 log10 N decibels (iii) In any 4 kHz band the center frequency of which is outside the authorized Digital Message Service band: At least 43+10 log10 (mean output power in Watts) decibels. (5) When using transmissions employing digital modulation techniques on the 900 MHz multiple address frequencies with a 12.5 kHz bandwidth, the power of any emission must be attenuated below the unmodulated carrier power of the transmitter (P) in accordance with the following schedule: (i) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (fd in kHz) of more than 2.5 kHz up to and including 6.25 kHz: At least 53 log10 (fd/2.5) decibels; (ii) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (fd in kHz) of more than 6.25 kHz up to and including 9.5 kHz: At least 103 log10 (fd/3.9) decibels; (iii) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (fd in kHz) of more than 9.5 kHz up to and including 15 kHz: At least 157 log10 (fd/5.3) decibels; (iv) On any frequency removed from the center of the authorized bandwidth by a displacement frequency greater than 15 kHz: At least 50 plus 10 log10(P) or 70 decibels, whichever is the lesser attenuation.

(c) The emission of an unmodulated carrier is prohibited except for test purposes as required for proper station and system maintenance.  101.113 Transmitter power limitations. (a) On any authorized frequency, the average power delivered to an antenna in this service must be the minimum amount of power necessary to carry out the communications desired. Application of this principle includes, but is not be limited to, requiring a licensee who replaces one or more of its antennas with larger antennas to reduce its antenna input power by an amount appropriate to compensate for the increased primary lobe gain of the replacement antenna(s). In no event shall the average equivalent isotropically radiated power (EIRP), as referenced to an isotropic radiator, exceed the values specified below. In cases of harmful interference, the Commission may, after notice and opportunity for hearing, order a change in the effective radiated power of this station. Further, the output power of a transmitter on any authorized frequency in this service may not exceed the following: ------------------------------------ | Maximum allowable | EIRP Frequency band |------------------ (MHz) | Fixed | Mobile | (dBW) | (dBW) ------------------------------------ 928.0 to 929.0 | +17 |........ 932.0 to 932.5 | +17 |........ 932.5 to 935.0 | +40 |........ 941.0 to 941.5 | +30 |........ 941.5 to 944.0 | +40 |........ 952.0 to 960.0 |(1)+40 |........ 1,850 to 1,990 | +45 |........ 2,110 to 2,160 |(4)+45 |........ 2,160 to 2,180 |(1)+45 |........ 2,180 to 2,200 | +45 |........ 2,450 to 2,500 | +45 |........ 2,686 to 2,690 | +45 |........ 3,700 to 4,200 | +55 |........ 5,925 to 6,425 | +55 |........ 6,425 to 6,525 | ........| +35 6,525 to 6,875 | +55 |........ 10,550 to 10,680 |(3)+55 |........ 10,700 to 11,700 | +55 |........ 12,200 to 13,250 |(4)+50 |........ 17,700 to 18,600 | +55 |........ 18,600 to 18,800 |(2)+35 |........ 18,800 to 19,700 | +55 |........ 21,200 to 23,600 |(4)+55 |........ 27,500 to 29,500 | +55 |........ 31,000 to 31,300 | 38,600 to 40,000 | +55 |........ -------------------------------------- (1) For multiple address operations,see  101.605(a)(1)(v). When an omnidirectional antenna is authorized in the 2150-2160 MHz band, the maximum power is 60 dBm. Remote alarm units that are part of a multiple address central station protection system are authorized a maximum of 2 watts. (2) The power delivered to the antenna is limited to -3 dBW. (3) Output power of a DEMS System nodal transmitter may not exceed 0.5 watts per 250 KHz. The output power of a DEMS System user transmitter may not exceed 0.04 watts per 250 KHz. The transmitter power in terms of the watts specified is the peak envelope power of the emission measured at the associated antenna input power. The operating power may not exceed the authorized power by more than 10 percent of the authorized power in watts at any time. (4) Also, see  101.145 and 101.605.  101.115 Directional antennas. (a) Unless otherwise authorized upon specific request by the applicant, each station authorized under the rules of this part must employ a directional antenna adjusted with the center of the major lobe of radiation in the horizontal plane directed toward the receiving station with which it communicates: provided, however, where a station communicates with more than one point, a multi- or omni-directional antenna may be authorized if necessary. New Periscope antenna systems will not, under ordinary circumstances, be authorized. (b) Stations operating below 2500 MHz that are required to use directional antennas must employ antennas meeting the standards indicated below. (Maximum beamwidth is for the major lobe of radiation at the half power points.

The maximum beamwidth requirement does not apply to DEMS User Stations. DEMS Nodal Stations need not comply with these standards. (2) The minimum front-to-back ratio must be 38 dBi. (3) Mobile, except aeronautical mobile, stations need not comply with these standards. (4) Except for antennas between 140ø and 180ø authorized or pending on January 1, 1989, in the band 10,550 to 10,565 MHz for which minimum radiation to suppression to angle (in degrees) from centerline of main beam is 36 decibels. (5) These antenna standards apply to all point-to-point stations authorized after June 1, 1997. Existing licensees and pending applicants on that date are grandfathered and need not comply with these standards. (6) These antenna standards apply to all point-to-point stations authorized on or before June 1, 1997. (7) These antenna standards apply only to DEMS User Stations licensed, in operation, or applied for prior to July 15, 1993. (8) Except for Multiple Address System frequencies listed in where omnidirectional antennas may be used. (9) Antennas used at outlying stations as part of a central protection alarm system need conform to only the following 2 standards: (1) The minimum on-beam forward gain must be at least 10 dBi, and (2) the minimum front-to-back ratio must be at least 20 dB. (10) Except as provided in Section 101.605. NOTE: Stations must employ an antenna that meets the performance standards for Category A, except that in areas not subject to frequency congestion, antennas meeting standards for Category B may be employed. Note, however, that the Commission may require the use of high performance antennas where interference problems can be resolved by the use of such antennas. (d) The Commission may require the replacement, prior to activation of the new facilities, at the licensee's expense, of any antenna or periscope antenna system of a permanent fixed station operating at 2500 MHz or higher that does not meet performance Standard A specified in paragraph (c) of this Section, upon a showing that said antenna causes or is likely to cause interference to (or receive interference from) any other authorized or applied for station whereas a higher performance antenna is not likely to involve such interference. Antenna performance is expected to meet the standards of paragraph (c) of this Section for parallel polarization. For cases of potential interference, an antenna will not be considered to meet Standard A unless the parallel polarization performance for the discrimination angle involved meets the requirements, even if the cross-polarization performance controls the interference. (e) In cases where passive reflectors are employed in conjunction with transmitting antenna systems, the foregoing paragraphs of this section also will be applicable. However, in such instances, the center of the major lobe of radiation from the antenna normally must be directed at the passive reflector, and the center of the major lobe of radiation from the passive reflector directed toward the receiving station with which it communicates. (f) New periscope antenna systems will be authorized for operation in private operational fixed stations upon a certification that the radiation, in a horizontal plane, from an illuminating antenna and reflector combination meets or exceeds the antenna standards of this section and, at locations where multiple periscope antennas are employed, that the cross-coupling between periscope antennas is suppressed by an amount equal to or greater than the radiation suppression specified in the standards for angles from the main beam of 140-180ø for the particular band and antenna category selected. In no event will periscope antennas be authorized in frequency bands shared with common carriers. (g) Periscope antennas used at an electric power facility plant area will be excluded from the requirements of paragraphs (c) and (e) of this section on a case-by-case basis where technical considerations preclude the use of other types of antenna systems. (h) In the event harmful interference is caused to the operation of other stations, the Commission may, after notice and opportunity for hearing, order changes to be made in the height, orientation, gain and radiation pattern of the antenna system.  101.117 Antenna polarization. Stations operating in the radio services included in this part are not limited as to the type of polarization of the radiated signal, provided, however, that in the event interference in excess of permissible levels is caused to the operation of other stations the Commission may, after notice and opportunity for hearing, order the licensee to change the polarization of the radiated signal. No change in polarization may be made without prior authorization from the Commission.  101.119 Simultaneous use of common antenna structures. The simultaneous use of common antenna structures by more than one radio station, or by one or more domestic public radio stations and one or more stations of any other class or service, may be authorized: Provided, however, That each licensee or user of any such structure is responsible for maintaining the structure, and for painting and illuminating the structure when obstruction marking is required by the Commission. (See  101.21(d).)  101.121 Marking of antenna structures. No permittee or licensee who has been required to paint or light an antenna structure may discontinue the required painting or lighting without having obtained prior written authorization therefor from the Commission. (For complete regulations relative to antenna marking requirements, see Part 17 of this chapter.)  101.123 Quiet zones. Quiet zones are those areas where it is necessary to restrict radiation so as to minimize possible impact on the operations of radio astronomy or other facilities that are highly sensitive to radio frequency interference. (a) In order to minimize possible harmful interference at the National Radio Astronomy Observatory site located at Green Bank, Pocohontas County, W. Va., and at the Naval Radio Research Observatory site at Sugar Grove, Pendleton County, W. Va., any applicant for a station authorization other than temporary-fixed seeking a station license for a new station or to modify an existing station in a manner which would change either the frequency, power, antenna height or directivity, or location of such a station within the area boarded by 39ø15' N. on the north, 78ø30' W. on the east, 37ø30' N. on the south, and 80ø30' W. on the west must at the time of filing such application with the Commission, simultaneously notify the Director, National Radio Astronomy Observatory, Post Office Box No. 2, Green Bank, W. Va. 24944, in writing, of the technical particulars of the proposed station. Such notification must include the geographical coordinates of the antenna, antenna height, antenna directivity if any, proposed frequency, type of emission and power. In addition, the applicant must indicate in his application to the Commission the date notification was made to the Observatory. After receipt of such applications, the Commission will allow a period of twenty (20) days for comments or objections in response to the notifications indicated. If an objection to the proposed operation is received during the 20-day period from the National Radio Astronomy Observatory for itself or on behalf of the Naval Radio Research Observatory, the Commission will consider all aspects of the problem and take whatever action is deemed appropriate. (b) Protection for Table Mountain Radio Receiving Zone, Boulder County, Colorado. Applicants for a station authorization to operate in the vicinity of Boulder County, Colorado under this part are advised to give due consideration, prior to filing applications, to the need to protect the Table Mountain Radio Receiving Zone from harmful interference. These are the research laboratories of the Department of Commerce, Boulder County, Colorado. To prevent degradation of the present ambient radio signal level at the site, the Department of Commerce seeks to ensure that the field strengths of any radiated signals (excluding reflected signals) received on this 1800 acre site (in the vicinity of coordinates 40ø07'50" N. Latitude, 105ø14'40" W. Longitude), resulting from new assignments or from the modification or relocation of existing facilities do not exceed 1 mV/m in the authorized bandwidth of service. (A field strength of 1 mV/m is equivalent to a power flux density of 85.8 dBW/M2 assuming a free-space characteristic impedance of 376.7 ohms.) (1) Advance consultation is recommended particularly for those applicants who have no reliable data which indicates whether the field strength or power flux density figures would be exceeded by their proposed radio facilities. In such instances, the following is a suggested guide for determining whether coordination is recommended: (i) All stations within 2.4 km (1.5 statute miles); (ii) Stations within 4.8 km (3 statute miles) with 50 watts or more effective radiated power (ERP) in the primary plane of polarization in the azimuthal direction of the Table Mountain Receiving Zone; (iii) Stations within 16 km (10 statute miles) with 1 kW or more ERP in the primary plane of polarization in the azimuthal direction of the Table Mountain Receiving Zone; (iv) Stations within 80 km (50 statute miles) with 25 kW or more ERP in the primary plane of polarization in the azimuthal direction of the Table Mountain Receiving Zone. (2) Applicants concerned are urged to communicate with the Radio Frequency Management Coordinator, Department of Commerce, Research Support Services, NOAA/R/E5X2, Boulder Laboratories, Boulder CO. 80303; telephone (303) 497-6548, in advance of filing their applications with the Commission. (3) The Commission will not screen applications to determine whether advance consultation has taken place. However, applicants are advised that such consultation can avoid objections from the Department of Commerce or proceedings to modify any authorization which may be granted which, in fact, delivers a signal at the site in excess of the field strength specified herein. (c) Applications for authorizations to construct microwave operational-fixed radio stations for transmission of program material to cable television systems will not be accepted, except in the frequency bands above 21,200 MHz. (d) Protection for Federal Communications Commission monitoring stations: (1) Applicants in the vicinity of an FCC monitoring station for a radio station authorization to operate new transmitting facilities or changed transmitting facilities which would increase the field strength produced over the monitoring station over that previously authorized are advised to give consideration, prior to filing applications, to the possible need to protect the FCC stations from harmful interference. Geographical coordinates of the facilities which require protection are listed in  0.121(c) of the Commission's Rules. Applications for stations (except mobile stations) which will produce on any frequency a direct wave fundamental field strength of greater than 10 mV/m in the authorized bandwidth of service (-65.8 dBW/m2 power flux density assuming a free space characteristic impedance of 120 ohms) at the referenced coordinates, may be examined to determine extent of possible interference. Depending on the theoretical field strength value and existing root-sum-square or other ambient radio field signal levels at the indicated coordinates, a clause protecting the monitoring station may be added to the station authorization. (2) In the event that calculated value of expected field exceeds 10 mV/m (-65.8 dBW/m2) at the reference coordinates, or if there is any question whether field strength levels might exceed the threshold value, advance consultation with the FCC to discuss any protection necessary should be considered. Prospective applicants may communicate with: Chief, Field Operations Bureau, Federal Communications Commission, Washington, D.C. 20554, Telephone (202) 632-6980. (3) Advance consultation is suggested particularly for those applicants who have no reliable data which indicates whether the field strength or power flux density figure indicated would be exceeded by their proposed radio facilities (except mobile stations). In such instances, the following is a suggested guide for determining whether an applicant should coordinate: (i) All stations within 2.4 kilometers (1.5 statute miles); (ii) Stations within 4.8 kilometers (3 statute miles) with 50 watts or more average effective radiated power (ERP) in the primary plane of polarization in the azimuthal direction of the Monitoring Stations. (iii) Stations within 16 kilometers (10 statute miles) with 1 kW or more average ERP in the primary plane of polarization in the azimuthal direction of the Monitoring Station; (iv) Stations within 80 kilometers (50 statute miles) with 25 kW or more average ERP in the primary plane of polarization in the azimuthal direction of the Monitoring Station; (4) Advance coordination for stations operating above 1000 MHz is recommended only where the proposed station is in the vicinity of a monitoring station designated as a satellite monitoring facility in  0.121(c) of the Commission's rules and also meets the criteria outlined in paragraphs (i) (2) and (3) of this section. (5) The Commission will not screen applications to determine whether advance consultation has taken place. However, applicants are advised that such consultation can avoid objections from the Federal Communications Commission or modification of any authorization which will cause harmful interference.  101.125 Temporary fixed antenna height restrictions. The overall antenna structure heights employed by mobile stations in the Local Television Transmission Service and by stations authorized to operate at temporary fixed locations may not exceed the height criteria set forth in Sec. 17.7 of this chapter, unless in each instance, authorization for use of a specific maximum antenna height (above ground and above mean sea level) for each location has been obtained from the Commission prior to erection of the antenna. Requests for such authorization must show the inclusive dates of the proposed operation. (Complete information as to rules concerning the construction, marking and lighting of antenna structures is contained in Part 17 of this chapter.)  101.127 Topographical data. Determining the location and height above sea level of the antenna site, the elevation or contour intervals must be taken from United States Geological Survey Topographic Quadrangle Maps, United States Army Corps of Engineers maps or Tennessee Valley Authority maps, whichever is the latest, for all areas for which such maps are available. If such maps are not published for the area in question, the next best topographic information should be used. Topographic data may sometimes be obtained from State and municipal agencies. Data from Sectional Aeronautical Charts (including bench marks) or railroad depot elevations and highway elevations from road maps may be used where no better information is available. In cases where limited topographic data is available, use may be made of an altimeter in a car driven along roads extending generally radially from the transmitter site. If it appears necessary, additional data may be requested. United States Geological Survey Topographic Quadrangle Maps may be obtained from the Department of the Interior, Geological Survey, Washington, DC 20242. Sectional Aeronautical Charts are available from the Department of Commerce, Coast and Geodetic Survey, Washington, DC 20230.  101.129 Transmitter location. (a) The applicant must determine, prior to filing an application for a radio station authorization, that the antenna site specified therein is adequate to render the service proposed. In cases of questionable antenna locations, it is desirable to conduct propagation tests to indicate the field intensity which may be expected in the principal areas or at the fixed points of communication to be served, particularly where severe shadow problems may be expected. In considering applications proposing the use of such locations, the Commission may require site survey tests to be made pursuant to a developmental authorization in the particular service concerned. In such cases, propagation tests should be conducted in accordance with recognized engineering methods and should be made with a transmitting antenna simulating, as near as possible, the proposed antenna installation. Full data obtained from such surveys and its analysis, including a description of the methods used and the name, address and qualifications of the engineer making the survey, must be supplied to the Commission. (b) Antenna structures should be so located and constructed as to avoid making them hazardous to air navigation. (See Part 17 of this chapter for provisions relating to antenna structures.) Such installation must be maintained in good structural condition together with any required painting or lighting.  101.131 Transmitter construction and installation. (a) The equipment at the operating and transmitting positions must be so installed and protected that it is not accessible to, or capable of being operated by, persons other than those duly authorized by the licensee. (b) In any case where the maximum modulating frequency of a transmitter is prescribed by the Commission, the transmitter must be equipped with a low-pass or band-pass modulation filter of suitable performance characteristics. In those cases where a modulation limiter is employed, the modulation filter must be installed between the transmitter stage in which limiting is effected and the modulated stage of the transmitter. (c) Each transmitter employed in these services must be equipped with an appropriately labeled pilot lamp or meter which will provide continuous visual indication at the transmitter when its control circuits have been placed in a condition to activate the transmitter. In addition, facilities must be provided at each transmitter to permit the transmitter to be turned on and off independently of any remote control circuits associated therewith. (d) At each transmitter control point the following facilities must be installed: (1) A carrier operated device which will provide continuous visual indication when the transmitter is radiating, or, in lieu thereof, a pilot lamp or meter which will provide continuous visual indication when the transmitter control circuits have been placed in a condition to activate the transmitter. (2) Facilities which will permit the operator to turn transmitter carrier on and off at will. (e) Transmitter control circuits from any control point must be so installed that grounding or shorting any line in the control circuit will not cause the transmitter to radiate: Provided, however, That this provision will not be applicable to control circuits of stations which normally operate with continuous radiation or to control circuits which are under the effective operational control of responsible operating personnel 24 hours per day.  101.133 Limitations on use of transmitters. (a) Transmitters licensed for operation in Common Carrier services may not be concurrently licensed or used for non-common carrier communication purposes except in the Multipoint Distribution Service (See Part 21 of this Chapter). However, mobile units may be concurrently licensed or used for non-common carrier communication purposes provided that the transmitter is type-accepted for use in each service. (b) Private operational fixed stations authorized in this service may communicate with associated operational-fixed stations and fixed receivers and with units of associated stations in the mobile service licensed under Private Radio Service rule parts. In addition, intercommunication is permitted with other licensed stations and with U.S. Government stations in those cases which require cooperation or coordination of activities or when cooperative use arrangements in accordance with  101.135 are contemplated; provided, however, that where communication is desired with stations authorized to operate under the authority of a foreign jurisdiction, prior approval of this Commission must be obtained; And provided further, That the authority under which such other stations operate does not prohibit the intercommunication. (c) Two or more persons or governmental entities eligible for private operational fixed licenses may use the same transmitting equipment under the following terms and conditions: (1) Each licensee complies with the general operating requirements set out in this Part. (2) Each licensee is eligible for the frequency(ies) on which the facility operates. (3) Each licensee must have the ability to access the transmitter(s) that it is authorized to operate under the multiple licensing arrangement.  101.135 Shared use of radio stations and the offering of private carrier service. (a) Licensees of Private Operational Fixed radio stations may share the use of their facilities on a non-profit basis or may offer service on a for-profit private carrier basis, subject to the following conditions and limitations: (1) Persons or governmental entities licensed to operate radio systems on any of the private radio frequencies set out in  101.101 may share such systems with, or provide private carrier service to, any eligible for licensing under this part, regardless of individual eligibility restrictions, provided that the communications being carried are permissible under  101.603. (2) The licensee must maintain access to and control over all facilities authorized under its license. (3) All sharing and private carrier arrangements must be conducted pursuant to a written agreement to be kept as part of the station records. (4) The licensee must keep an up-to-date list of system sharers and private carrier subscribers and the basis of their eligibility under this part. Such records must be kept current and must be made available upon request for inspection by the Commission.  101.137 Interconnection of private operational fixed microwave stations. Private operational fixed stations may be interconnected with facilities of common carriers subject to applicable tariffs.  101.139 Authorization of transmitters. (a) Except for transmitters used at developmental stations or for fixed point-to-point operation pursuant to Subparts H and I, each transmitter must be a type which has been type accepted by the Commission for use under the applicable rules of this part. Transmitters used in the point-to-point microwave service under Subparts H and I for fixed operation must be of a type that has been either notified or type accepted by the Commission (see Sec. 2.904(d) of this chapter). Effective March 5, 1984, only grants of notification will be issued for transmitters used exclusively for fixed point-to-point operation. Transmitters designed for use in the 31.0 to 31.3 GHz band will be authorized under the notification procedure. (b) Any manufacturer of a transmitter to be produced for use under the rules of this part may request type acceptance or notification by following the applicable procedures set forth in Part 2 of this chapter. Type accepted and notified transmitters are included in the Commission's Radio Equipment List. Copies of this list are available for inspection at the Commission's office in Washington, D.C. and at each of its field offices. (c) Type acceptance or notification for an individual transmitter may also be requested by an applicant for a station authorization, pursuant to the procedures set forth in Part 2 of this chapter. An individual transmitter will not normally be included in the Radio Equipment List but will be enumerated on the station authorization. (d) A transmitter presently shown on an instrument of authorization, which operates on an assigned frequency in the 890-940 MHz band and has not been type accepted, may continue to be used by the licensee without type acceptance provided such transmitter continues otherwise to comply with the applicable rules and regulations of the Commission. (e) Type acceptance or notification is not required for portable transmitters operating with peak output power not greater than 250 mW. If operation of such equipment causes harmful interference the FCC may, at its discretion, require the licensee to take such corrective action as is necessary to eliminate the interference. (f) After July 15, 1996, the manufacture (except for export) or importation of equipment employing digital modulation techniques in the 3700-4200, 5925-6425, 6525-6875, 10,550-10,680 and 10,700-11,700 MHz bands must meet the minimum payload capacity requirements of  101.139.  101.141 Microwave digital modulation. (a) Microwave transmitters employing digital modulation techniques and operating below 15 GHz must, with appropriate multiplex equipment, comply with the following additional requirements: (1) The bit rate, in bits per second, must be equal to or greater than the bandwidth specified by the emission designator in Hertz (e.g., to be acceptable, equipment transmitting at a 20 Mb/s rate must not require a bandwidth of greater than 20 MHz), except the bandwidth used to calculate the minimum rate may not include any authorized guard band. (2) Equipment to be used for voice transmission placed in service, authorized, or applied for on or before June 1, 1997 in the 2110 to 2130 and 2160 to 2180 MHz bands must be capable of satisfactory operation within the authorized bandwidth to encode at least 96 voice channels. Equipment placed in service, authorized, or applied for on or before June 1, 1997 in the 3700-4200, 5925-6425 (30 MHz bandwidth), and 10,700-11,700 MHz (30 and 40 MHz bandwidths) bands must be capable of satisfactory operation within the authorized bandwidth to encode at least 1152 voice channels. These required loading levels may be reduced by a factor of 1/N provided that N transmitters may be operated satisfactorily, over the same radio path, within an authorized bandwidth less than, or equal to, the maximum authorizable bandwidth (e.g., the 1152 channel requirement may be reduced to 576 if two transmitters can be satisfactorily operated over the same path within the maximum bandwidth). Where type accepted equipment is designed to operate on the same frequency in a cross polarized configuration to meet the above capacity requirements, the Commission will require, at the time additional transmitters are authorized, that both polarizations of a frequency be used before a new frequency assignment is made, unless a single transmitter installation was found to be justified by the Commission at the time it authorized the first transmitter. (3) The following capacity and loading requirements must be met for equipment applied for, authorized, and placed in service after June 1, 1997 in the 3700-4200 MHz (4 GHz), 5925-6425 and 6525-6875 MHz (6 GHz), 10,550-10,680 MHz (10 GHz), and 10,700-11,700 MHz (11 GHz) bands: Nominal Minimum Minimum Channel Payload Traffic Loading Bandwidth Capacity Payload (as percent Typical (MHz) (Mbits/s) of payload capacity) Utilization* ______________________________________________________________ 0.400 1.54 n/a 1 DS-1 0.800 3.08 n/a 2 DS-1 1.25 3.08 n/a 2 DS-1 1.60 6.17 n/a 4 DS-1 2.50 6.17 n/a 4 DS-1 3.75 12.3 n/a 8 DS-1 5.0 18.5 n/a 12 DS-1 10.0 44.7 50** 1 DS-3/STS-1 20.0 89.4 50** 2 DS-3/STS-1 30.0 (11 GHz) 89.4 50** 2 DS-3/STS-1 30.0 (6 GHz) 134.1 50** 3 DS-3/STS-1 40.0 134.1 50** 3 DS-3/STS-1 * DS and STS refer to the number of voice circuits a channel can accommodate. 1 DS-1 = 24 voice circuits; 2 DS-1 = 48; 4 DS-1 = 96; 8 DS-1 = 192; 12 DS-1 = 288; 1 DS- 3/STS-1 = 672; 2 DS-3/STS-1 = 1344; 3 DS-3/STS-1 = 2016. ** This loading requirement must be met within 30 months of licensing. If two transmitters simultaneously operate on the same frequency over the same path, the requirement is reduced to 25 percent. (4) If a transmitter is authorized to operate in a bandwidth that is not listed in paragraph (a)(3) of this section, it must meet the minimum payload capacity and traffic loading requirements of the next largest channel bandwidth listed in the table; e.g., if the authorized bandwidth is 3.5 MHz, the minimum payload capacity must be 12.3 Mbits/s. (5) Transmitters carrying digital motion video motion material are exempt from the requirements specified in paragraphs (a)(2) and (a)(3) of this section, provided that at least 50 percent of the payload is digital video motion material and the minimum bit rate specified in paragraph (a)(1) is met. In the 6, 10, and 11 GHz bands, concatenation of multiple contiguous channels is permitted for channels of equal bandwidth on center frequencies, provided no other channels are available and the minimum payload capacity requirements are met. (b) For purposes of compliance with the emission limitation requirements of  101.111(a)(2) of this part and the requirements of paragraph (a) of this section, digital modulation techniques are considered as being employed when digital modulation occupies 50 percent or more to the total peak frequency deviation of a transmitted radio frequency carrier. The total peak frequency deviation will be determined by adding the deviation produced by the digital modulation signal and the deviation produced by any frequency division multiplex (FDM) modulation used. The deviation (D) produced by the FDM signal must be determined in accordance with  2.202(f) of Part 2 of this chapter. (c) Transmitters employing digital modulation techniques must effectively eliminate carrier spikes or single frequency tones in the output signal to the degree which would be obtained without repetitive patterns occurring in the signal. (d) Transmitters type accepted for use with digital modulation prior to November 1, 1974 may continue to be used where authorized until December 31, 1976. After the latter date, such equipment will no longer be type accepted for digital modulation unless it is type accepted for such use after November 1, 1974. (e) Microwave transmitters employing digital modulation techniques in the bands 17,700-19,700 MHz must transmit at bit rate, in bits per second (bps), equal to or greater than the authorized bandwidth in Hertz (e.g., to be acceptable, equipment transmitting at a 20 Mbps rate must not require an authorized bandwidth greater than 20 MHz). This bps/Hz standard is independent of the antenna (polarization) used, frequency reuse, or how the system is configured. NOTE: Until December 1, 1988, no minimum bit rate will apply to the 17,700-19,700 MHz band. Systems authorized prior to that date may install equipment after that date with no minimum bit rate.  101.143 Minimum path lengths for fixed lengths. (a) The distance between end points of a fixed link in the private operational fixed service and the point- to-point service must equal or exceed the value set forth in the table below or the EIRP must be reduced in accordance with the equation set forth below. Minimum path Frequency Band (MHz) length (km) ________________________________________________________________ Below 1,850.............................................n/a 1,850 to 7,125..........................................17 10,550 to 13,250........................................5 Above 17,700...........................................n/a (b) For paths shorter than those specified in the Table, the EIRP may not exceed the value derived from the following equation. EIRP = 30 - 20 log[A/B], dBW Where: EIRP = Equivalent isotropic radiated power in dBW. A = Minimum path length from the Table for the frequency band in kilometers. B= The actual path length in kilometers. NOTE: Automatic transmit power control may be used to meet this requirement up to a 3 dB increase in EIRP. (c) Upon an appropriate technical showing, applicants and licensees unable to meet the minimum path length requirement may be granted an exception to these requirements.  101.145 Interference to geostationary-satellites. These limitations are necessary to minimize the probability of harmful interference to reception in the bands 2655-2690 MHz, 5925-6875 MHz, and 12.7-12.75 GHz on board geostationary-space stations in the fixed-satellite service (Part 25). (a) Stations authorized prior to July 1, 1976 in the band 2655-2690 MHz, which exceed the power levels in paragraphs (a) and (b) of this section are permitted to operate indefinitely, provided that the operations of such stations does not result in harmful interference to reception in these band on board geostationary space stations. (b) 2655 to 2690 MHz and 5925 to 6875 MHz. No directional transmitting antenna utilized by a fixed station operating in these bands may be aimed within 2 degrees of the geostationary-satellite orbit, taking into account atmospheric refraction. However, exception may be made in unusual circumstances upon a showing that there is no reasonable alternative to the transmission path proposed. If there is no evidence that such exception would cause possible harmful interference to an authorized satellite system, said transmission path may be authorized on waiver basis where the maximum value of the equivalent isotropically radiated power (EIRP) does not exceed: (1) +47 dBW for any antenna beam directed within 0.5 degrees of the stationary satellite orbit or (2) +47 to +55 dBW, on a linear decibel scale (8 dB per degree) for any antenna beam directed between 0.5 degrees and 1.5 degrees of the stationary orbit. (c) 12.7 to 12.75 GHz. No directional transmitting antenna utilized by a fixed station operating in this band may be aimed within 1.5 degrees of the geostationary-satellite orbit, taking into account atmospheric refraction. However, exception may be made in unusual circumstances upon a showing that there is no reasonable alternative to the transmission path proposed. If there is no evidence that such exception would cause possible harmful interference to an authorized satellite system, said transmission path may be authorized on waiver basis where the maximum value of the equivalent isotropically radiated power (EIRP) does not exceed +45 dBW for any antenna beam directed within 1.5 degrees of the stationary satellite orbit. (d) Methods for calculating the azimuths to be avoided may be found in: CCIR Report No. 393 (Green Books), New Delhi, 1970; in "Radio-Relay Antenna Pointing for controlled Interference With Geostationary-Satellites" by C.

Frequencies normally available for assignment in this service are set forth with applicable limitations in the following tables: (a) 928-960 MHz. Multiple address system (MAS) frequencies are available for the point-to-multipoint transmission of a licensee's products or services, excluding video entertainment material, to a licensee's customer or for its own internal communications. The paired frequencies listed in this section are used for two-way interrogate/ response communications between a master station and remote stations. Each master station operating on these frequencies is required to serve a minimum of four separate active remote stations. Ancillary one-way communications on paired frequencies are permitted on a case-by-case basis. Ancillary communications between interrelated master stations are permitted on a secondary basis. The normal channel bandwidth assigned will be 12.5 kHz. Upon adequate justification, however, channels with bandwidths up to 50 kHz may be authorized. Tables 2, 4, and 6 list frequencies with 25 kHz bandwidth channels. When licensed for a larger bandwidth, the system still is required to use equipment that meets the +/-0.00015 percent tolerance requirement. (See  101.107). Systems licensed for frequencies in these MAS bands prior to August 1, 1975, may continue to operate as authorized until June 11, 1996, at which time they must comply with current MAS operations based on the 12.5 kHz channelization set forth in this paragraph. Systems licensed between August 1, 1975, and January 1, 1981, inclusive, are required to comply with the grandfathered 25 kHz standard bandwidth and channelization requirements set forth in this paragraph.

(r) Frequency diversity transmission will not be authorized in this service in the absence of a factual showing that the required communications cannot practically be achieved by other means. Where frequency diversity is deemed to be justified on a protection channel basis, it must be limited to one protection channel for the bands 3700-4200, 5925-6425, and 6525-6875 MHz, and a ratio of one protection channel for three working channels for the bands 10,550-10,680 and 10,700-11,700 MHz. In the bands 3700-4200, 5925-6425, and 6525-6875 MHz, no frequency diversity protection channel will be authorized unless there is a minimum of three working channels, except that where a substantial showing is made that a total of three working channels will be required within three years, a protection channel may be authorized simultaneously with the first working channel. A protection channel authorized under such exception will be subject to termination if applications for the third working channel are not filed within three years of the grant date of the applications for the first working channel. Where equipment employing digital modulation techniques with cross-polarized operation on the same frequency is used, the protection channel authorized under the above conditions may be considered to consist of both polarizations of the protection frequency where such is shown to be necessary.  101.607 Maximum authorized bandwidth The maximum bandwidth which will be authorized per frequency assigned is set out in the table that follows. Regardless of the maximum authorized bandwidth specified for each frequency band, the Commission reserves the right to issue a license for less than the maximum bandwidth if it appears that a lesser bandwidth would be sufficient to support an applicant's intended communications.

An application requesting such authorization must fully describe the modulation, emission, and bandwidth desired and must specify the bandwidth to be occupied.  101.709 Modulation requirements. When amplitude modulation is used, the modulation percentage must be sufficient to provide efficient communication, and must normally be maintained above 70 percent on positive peaks but may not exceed 100 percent on negative peaks.  101.711 Permissible communications. Stations in this service are authorized to render any kind of communication service provided for in the legally applicable tariffs of the carrier, unless otherwise directed in the applicable instrument of authorization or limited by  101.703 or  101.707.  101.713 Supplementary showing required with applications. (a) All applicants for regular authorization under this subpart must, before filing an application, amendments to a pending application or modifications to a license, prior coordinate the proposed frequency usage with existing users in the area and other applicants with previously filed applications in accordance with the procedures in  101.103 except that stations authorized under  101.715 may complete the prior coordination process orally and the period allowed for response to a coordination notification may be less than 30 days if the parties agree. (b) In those frequency bands shared with the communication-satellite service and applicant for a new station, for new points of communication, for the initial frequency assignment in a shared band for which coordination has not been previously effected, or for authority to modify the emission or radiation characteristics of an existing station in a manner that may increase the likelihood of harmful interference, must ascertain in advance whether the station(s) involved lie within the great circle coordination distance contours of an existing Earth station or one for which an application has been accepted for filing, and must coordinate his proposal with each such Earth station operator or applicant. For each potential interference path, the applicant must perform the computations required to determine that the expected level of interference to or from the terrestrial station does not exceed the maximum permissible interference power level in accordance with the technical standards and requirements of Secs. 25.251- 25.256 of this chapter. In those instances where the results of these computations indicate a safety margin of less than 5 dB, the applicant must submit with the application to the Commission, certain additional information; the gains assumed for both the terrestrial and Earth station antennas in the direction of the other station; the calculated transmission loss; and the resulting margin above the controlling objective. The Commission may, in the course of examining any application, require the submission of additional showings, complete with pertinent data and calculations in accordance with Part 25 of this chapter, showing that harmful interference will not likely result from the proposed operation. (Technical characteristics of the Earth stations on file and coordination contour maps for those Earth stations will be kept on file for public inspection in the offices of the Commission's Common Carrier Bureau in Washington, D.C.) (c) Each applicant filing pursuant to paragraph (c) of this section must also ascertain in advance whether the beam of his proposed antenna(s) intersects the beam of any Earth station antenna within the rain scatter coordination distance contour of which the terrestrial antenna is located, below the altitude given in table 1 of Sec. 25.254(b) of this chapter for the rain climate in which the Earth station is located. In general such intersections will not be permitted. For the purposes of this paragraph, the beam of an antenna is to be taken as that portion of the antenna radiation pattern inside of which the gain is within 15 dB of the maximum antenna gain. The concepts of rain climate and rain scatter coordination distance contour are as defined in Sec. 25.254 of this chapter. In certain cases, for good cause shown, intersections may be permitted on an individual waiver basis. In such cases, the applicant must also submit with his application a showing setting forth (1) the nature of the proposed beam intersection, (2) the Earth station operator or applicant with whom coordination was attempted and the results of the coordination, and (3) the technical basis on which it was concluded that harmful interference will not likely result from this beam intersection.  101.715 Stations at temporary fixed locations. (a) Authorizations may be issued upon proper application for the use of frequencies listed in  101.703(a) by stations in the Point-to-Point Microwave Radio Service for rendition of temporary service to subscribers under the following conditions: (1) When a fixed station is to remain at a single location for less than six months, the location is considered to be temporary. Services which are initially known to be of longer than 6 months' duration may not be provided under a temporary fixed authorization but rendered pursuant to a regular license. (2) When a fixed station, authorized to operate at temporary locations, is to remain at a single location for more than six months, an application (FCC Form 494) for a station authorization designating that single location as the permanent location must be filed at least 30 days prior to the expiration of the six-month period. (3) The station must be used only for rendition of communication service at a remote point where the provision of wire facilities is not practicable. (4) The antenna structure height employed at any location may not exceed the criteria set forth in Sec. 17.7 of this chapter unless, in each instance, authorization for use of a specific maximum antenna structure height for each location has been obtained from the Commission prior to erection of the antenna. See  101.125. (b) Applications for authorizations to operate stations at temporary locations under the provisions of this section must be made upon FCC form 494. Blanket applications may be submitted for the required number of transmitters.  101.717 Notification of station operation at temporary fixed locations. (a) The licensee of stations which are authorized pursuant to the provisions of  101.715 must notify the Commission at least 5 days prior to installation of the facilities, stating: (1) The call sign, manufacturer's name, type or model number, output power and specific location of the transmitter(s). (2) The maintenance location for the transmitter. (3) The location of the transmitting or receiving station with which it will communicate and the identity of the correspondent operating such facilities. (4) The exact frequency or frequencies to be used. (5) The public interest, convenience and necessity to be served by operation of the proposed installation. (6) The commencement and anticipated termination dates of operation from each location. In the event the actual termination date differs from the previous notification, written notice thereof promptly must be given to the Commission. (7) A notification must include compliance with the provisions of  101.713 (c) when operations are to be conducted in the area of other terrestrial microwave stations and with the provisions of  101.713(c) and (d) when operations are to be conducted within the coordination distance contours of a fixed earth station. (8) Where the notification contemplates initially a service which is to be rendered for a period longer than 90 days, the notification must contain a showing as to why application should not be made for regular authorization. (b) Less than 5 days advance notice may be given when circumstances require shorter notice provided such notice is promptly given and the reasons in support of such shorter notice are stated. (c) A copy of the notification must be kept with the station license.  101.719 Renewal of station licenses. (a) An application for renewal of a station license in the Point-to-Point Microwave Radio Service primarily used to relay television signals must contain: (1) A statement that such use complies with  101.701(b); and (2) The demonstration required by  101.701(c). Applications that do not contain these items as appropriate will be returned as unacceptable for filing. (b) Any application for renewal of license, for a term commencing January 1, 1975, or after, involving facilities utilizing frequency diversity must contain a statement showing compliance with  101.103(c) or the exceptions recognized in paragraph 141 of the "First Report and Order" in Docket No. 18920 (FCC 71-547). If not in compliance, a complete statement with the reasons therefor must be submitted.  101.721 Channel loading. .Except for video transmission, an application for an initial working channel for a given route will not be accepted for filing where the anticipated loading (within 30 months for data and five years for voice, or other period subject to reasonable projection) is less than the minimum specified for the following frequency bands. Absent extraordinary circumstances, applications proposing additional frequencies over existing routes will not be granted unless it is shown that the traffic load will shortly exhaust the capacity of the existing equipment. For the 3700-4200 MHz band, all persons intending to utilize baseband frequencies above 7.3 MHz, or to operate with more than 1500 equivalent 4 kHz voice channels per radio channel, must submit evidence of coordination pursuant to  101.103(d). Where no construction of radio facilities is requested, licensees must submit this evidence with their filing of any necessary authority required pursuant to section 214 of the Communications Act and Part 63 of this chapter. _______________________________________________________________ Minimum Minimum Frequency band number of original (MHz) voice channels data (4 kHz or loading equivalent) (Mb/s) ________________________________________________________________ 3700 to 4200 900* 44.7 (20 MHz bandwidth) 5925 to 6425 22.3 (10 MHz bandwidth) 5925 to 6425 44.7 (20 MHz bandwidth) 5925 to 6425 900* 67.0 (30 MHz bandwidth) 10,700 to 11,700 (10 MHz bandwidth) 240 22.3 10,700 to 11,700 (20 MHz bandwidth) 240 44.7 10,700 to 11,700 (30 MHz bandwidth) 900* 44.7 10,700 to 11,700 (40 MHz bandwidth) 900* 67.0 ________________________________________________________________ * Where transmitters employing digital modulation techniques are designed to be used so that two may simultaneously operate on the same frequency over the same path, the minimum number of voice channels is reduced to 500 per transmitter.  101.723 Special requirements for operation in the band 38,600-40,000 MHz.
