FREQUENCY COORDINATION AND INTERFERENCE ANALYSIS REPORT Prepared for RAYTHEON COMPANY OAHU, HI Satellite Earth Station Prepared By: COMSEARCH 19700 Janelia Farm Boulevard Ashburn, VA 20147 July 28, 2004

TABLE OF CONTENTS 1. CONCLUSIONS 3 2. SUMMARY OF RESULTS 4 3. SUPPLEMENTAL SHOWING 5 4. EARTH STATION COORDINATION DATA 6 5. CERTIFICATION 10 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.

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 Verizon Hawaii. Inc. AT&T Wireless Services of Hawaii, Inc. No other carriers reported potential interference cases. 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. Coordination data for this earth station was sent to the below listed carriers with a letter dated 06/10/2004. Company AT&T Corp-Govt Mkts Hawaii Inf Transfer AT&T Wireless Services of Hawaii, Inc. Hawaii State Honolulu City & County University of Hawaii Verizon Hawaii, Inc.
