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 after
frequency offsets. Further, there will be no other 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 and frequency
offsets are considered on the interfering paths, sufficient blockage exists to negate
harmful interference from occurring with the proposed transmit-receive earth station.

Stratos Offshore Services Company

No other carriers reported potential interference cases.
