Iridium Constellation LLC Ka-Band Earth Station – Fairbanks, AK (E050282) Frequency Coordination Report 28 GHz 1. Summary of Results On behalf of Iridium Constellation, Comsearch performed a coordination notice for all existing and proposed terrestrial licenses within the coordination contours of their existing Ka-Band earth station in Fairbanks, Alaska, licensed under call sign E050282, 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 27, 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 Iridium Constellation 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 Fairbanks, Alaska 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 21, 2016. These licensees are authorized to operate temporary fixed operations from 27.5 to 29.5 GHz on a statewide or nationwide basis. Licensee Authorized Geographic Area AT&T Alascom Statewide: Alaska Frontier Continental US General Communication Inc. Statewide: Alaska A notification letter and datasheet for the Ka-Band earth station in Fairbanks, Alaska were also sent to the following 28 GHz local television transmission licensee on June 21, 2016. This licensee is authorized to operate temporary fixed operations from 27.5 to 29.5 GHz on a nationwide basis. Licensee Authorized Geographic Area Information Super Station, LLC Continental US No objections were received from the common carrier or local television transmission service incumbents. 1 The proposed earth station will operate in the 29.1 – 29.3 GHz portion of the Ka-Band.
