    1. Summary of Results
On behalf of Ob3 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, VA, 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 October 18, 2017.

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 secondary basis to LMDS Block A operations and 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 Bristow, VA 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. These licensees are
authorized to operate temporary fixed operations from 27.5 – 29.5 GHz on a nationwide basis or
local basis.
