FREQUENCY COORDINATION AND INTERFERENCE ANALYSIS REPORT Prepared for SOLO SATELLITE COMMUNICATIONS MIAMI, FL Satellite Earth Station Prepared By: COMSEARCH 19700 Janelia Farm Boulevard Ashburn, VA 20147 March 25, 2011

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. 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. No 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. Coordination data for this earth station was sent to the below listed carriers with a letter dated 03/25/2011. Company Embarq Florida, Inc. FLORIDA POWER AND LIGHT COMPANY Federal Communications Commission METROPOLITAN AREA NETWORKS, INC. Miami-Dade County New Cingular Wireless PCS LLC - S FL Palm Beach County Facilities Dev & Ops South Florida Water Management District Verizon Wireless Personal Comm, LP(S FL) The following section presents the data pertinent to frequency coordination of the proposed earth station that was circulated to all carriers within its coordination contours.
