1. CONCLUSIONS

An interference study considering all existing, proposed and prior coordinated microwave
facilities within the coordination contours of the proposed earth station demonstrates that
this site will operate satisfactorily with the common carrier microwave environment.
Further, there will be no restrictions of its operation due to interference considerations.

Frequency Coordination and Interference Analysis Report 06/29/2018 Page 3 of 30

2. SUMMARY OF RESULTS

A number of great circle interference cases were identified during the interference study of
the proposed earth station. Each of the cases, which exceeded the interference objective
on a line-of-sight basis, was profiled and the propagation losses estimated using NBS
TN101 (Revised) techniques. The losses were found to be sufficient to reduce the signal
levels to acceptable magnitudes in every case.

1. CONCLUSIONS

An interference study considering all existing, proposed and prior coordinated microwave
facilities within the coordination contours of the proposed earth station demonstrates that
this site will operate satisfactorily with the common carrier microwave environment.
Further, there will be no restrictions of its operation due to interference considerations.

2. SUMMARY OF RESULTS

A number of great circle interference cases were identified during the interference study of
the proposed earth station. Each of the cases, which exceeded the interference objective
on a line-of-sight basis, was profiled and the propagation losses estimated using NBS
TN101 (Revised) techniques. The losses were found to be sufficient to reduce the signal
levels to acceptable magnitudes in every case.
