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 04/26/2012 Page 3 of 10

2. SUMMARY OF RESULTS No great circle interference cases were identified within the coordination contours during the interference study of the proposed earth station. There are no unresolved interference objections with this proposed facility. Frequency Coordination and Interference Analysis Report 04/26/2012 Page 4 of 10

3. SUPPLEMENTAL SHOWING Pursuant to Part 25.203(c) of the FCC Rules and Regulations, the satellite earth station proposed in this application was coordinated by Comsearch using computer techniques and in accordance with Part 25 of the FCC Rules and Regulations. No carriers were identified within the coordination contours of the proposed earth station site. Frequency Coordination and Interference Analysis Report 04/26/2012 Page 5 of 10

4. EARTH STATION COORDINATION DATA This section presents the data pertinent to frequency coordination of the proposed earth station that was circulated to all carriers within its coordination contours. Frequency Coordination and Interference Analysis Report 04/26/2012 Page 6 of 10
