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.

    Summary of Results
On behalf of General Dynamics Mission Systems, Comsearch performed a coordination notice
for all existing and proposed terrestrial licenses within the coordination contours of their
proposed Ka-Band earth station in Wahiawa, Hawaii, which will transmit at 28 GHz1. Prior-
notification letters were sent to the licensees and a copy of the notification data is provided in
section four of this report. The earth station coordination was finalized on January 3, 2017.

No objections were received from any of the incumbent 28 GHz licensees.




    28 GHz Common Carrier and LTTS Coordination

In accordance with FCC Rules and Regulations, the Ka-Band earth station in Wahiawa, Hawaii
was prior-coordinated by Comsearch. A notification letter and datasheet for this earth station
were sent to the following 28 GHz common carrier fixed microwave licensees on November 28,
2016. These licensees are authorized to operate on frequencies that overlap the frequency
range of the proposed earth station.
