\fcharset0\fnil Arial;}}\plain\cf1\fs20 \pard Description: This 
Mathcad sheet is based in part on ITU-R Rec. P.618-6, Section 2.2.  
The procedure in ITU-R P.618-6 Section 2.2 estimates the long-term 
statistics of slant path rain attenuation exceed over a 
satellite-to-earth path, for percentage of the year ranging from 
0.001% to 5%, for a given location, up to 55 GHz.  Where appropriate, 
portions other ITU Recommendations are included to make this worksheet 
as stand-alone as possible. In addition, some geometry calculations 
are included that are not in P.618 in order to simplify the input 
parameters.\par \par The sheet also calculates the rain margin for the 
BSS system and using the rain-attenuation vs. probability relation 
from ITU-R Rec. P618-6, determines the percent of time that a rain 
outage can be expected for the average year and the maximum C/I that 
should be received at the BSS receiver from an MVDDS transmitter 
assuming that the MVDDS system increases the BSS outage time by 2.68% 
and other interference-caused outage values.  }
