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, based upon the restrictions noted in the Summary of Results (Section 2). Frequency Coordination and Interference Analysis Report 11/05/2011 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 most cases. 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 and frequency separation are considered on the interfering paths, sufficient losses exist to negate harmful interference from occurring with the proposed transmit-receive earth station. Further, the transmit spectrum will be limited to frequencies 5925.0 to 6181.0 MHz, 6214.0 to 6240.0 MHz, and 6273.0 to 6425.0 MHz. Company Duke Energy Carolinas LLC GTE Mobilnet of Indiana Ltd. Indiana, State of (IPSC) No other carriers reported potential interference cases. Frequency Coordination and Interference Analysis Report 11/05/2011 Page 4 of 10
