    1. Summary of Results
On behalf of O3b Networks, Comsearch performed a coordination notice for all existing and
proposed terrestrial licenses within the coordination contours of their proposed Ka-Band earth
station in Manassas, Virginia, 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 July 8, 2016.

No objections were received from any of the incumbent 28 GHz licensees. Our notification to
the LMDS incumbents was performed under the assumption that the earth station would be
operating on a non-interference basis in relation to primary LMDS Block A operations. A
contact at O3b Networks has been provided in case any concerns may arise in the future.


    2. 28 GHz Common Carrier and LTTS Coordination
In accordance with FCC Rules and Regulations, the Ka-Band earth station in Manassas,
Virginia was prior-coordinated by Comsearch. A notification letter and datasheets for this earth
station were sent to the following 28 GHz common carrier fixed microwave licensees on June
27, 2016. These licensees are authorized to operate temporary fixed operations from 27.5 to
29.5 GHz over a designated geographic area.

A notification letter and datasheets for the Ka-Band earth station in Manassas, Virginia were
also sent to the following 28 GHz local television transmission licensee on June 27, 2016. This
licensee is authorized to operate temporary fixed operations from 27.5 to 29.5 GHz on a
nationwide basis.

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.
