    1. Summary of Results
On behalf of HUGHES NETWORK SYSTEMS LIMITED, Comsearch performed a coordination
notice for all existing and proposed terrestrial licenses within the coordination contours of their
proposed Ka-Band earth station in Rapid City, SD, 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 4, 2019.

No objections were received from any of the incumbent 28 GHz licensees. Our notification to
the UMFUS incumbents was performed under the assumption that the earth station would be
operating on a secondary basis to UMFUS L1 & L2 Block operations and a contact at Hughes
Network Systems Limited 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 Rapid City, SD 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.
