FREQUENCY COORDINATION AND INTERFERENCE ANALYSIS REPORT Prepared for SOLO SATELLITE COMMUNICATIONS MEMPHIS, TN Satellite Earth Station Prepared By: COMSEARCH 19700 Janelia Farm Boulevard Ashburn, VA 20147 February 12, 2010 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. Operation will be restricted to the satellite and frequency shown in the attached frequency coordination data. 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-only earth station. Company New Cingular Wireless PCS, LLC - KS/MO Verizon Wireless Tennessee Partnership No other carriers reported potential interference cases.

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. Verbal and written coordination was conducted with the carriers listed below on 02/11/2010. Company ALLTEL New License Sub LLC AT&T COMM.
