O3b Networks USA, LLC Ka-Band Earth Station – Vernon, TX Frequency Coordination Report - Revised 28 GHz 1. Summary of Results On behalf of O3B Networks USA, LLC’s proposed earth station transmitting at 28 GHz1, Comsearch performed a revised coordination notice for all existing and proposed terrestrial licenses within the coordination contours of the Ka-Band station in Vernon, Texas. The revision was performed due to a minor coordinate change in the location of the proposed earth station. 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 20, 2013. 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, a Ka-Band earth station in Vernon, TX was prior coordinated by Comsearch.
