1. CONCLUSIONS An interference study for the proposed temporary testing considering all existing, proposed and prior coordinated microwave facilities within the coordination contours demonstrates that this earth station 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 04/20/2009 Page 3 of 13

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 most every case. Those cases that did not clear with terrain profiles will be resolved by either uplink power reduction, or frequency offset.
