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, based
upon the restrictions noted in the Summary of Results (Section 2).

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
offset are considered on the interfering paths, sufficient losses exist to negate harmful
interference from occurring with the proposed transmit-receive earth station. Further, the
receive spectrum will be limited to frequencies 3922 to 3942 MHz, and the transmit
spectrum will be limited to frequencies 6147 to 6167 MHz.


       Company

       None



No carriers reported potential interference cases.
