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. 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 THAT

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

AND RECEIVE EARTH STATION. CLOSE IN LOCAL SHIELDING WAS USED TO CLEAR TWO OF THE

POTENTIAL CASES.

3. SUPPLEMENTAL SHOWING
   RE: PART 25.203(C)




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 JULY 23, 2002.

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.



No carriers reported potential interference cases involving this earth station.
