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. This earth station will be limited to operations of the bandwidths shown in Section 4 of this report. Frequency Coordination and Interference Analysis Report 10/01/2012 Page 3 of 10

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. The following companies reported potential great circle interference conflicts that did not meet the objectives on a line-of-sight basis. When over-the-horizon losses are considered on the interfering paths, sufficient blockage exists to negate harmful interference from occurring with the proposed transmit-receive earth station. Company Centerpoint Energy Field Services Central Louisiana License Co., LLC Lousiana Dept. of Transportation and Dev New Cingular Wireless PCS, LLC - LA, GM Wireless Infrastructure Partners, LLC No other carriers reported potential interference cases.
