The FCC Office of Engineering and Technology will begin a 45-day public trial of Comsearch’s TV band database system Tuesday. The trial is intended to let the public access and test Comsearch’s database system “to ensure that it correctly identifies channels that are available for unlicensed radio transmitting devices that operate in the TV band ... properly registers radio transmitting facilities entitled to protection, and provides protection to authorized services and registered facilities as specified in the rules,” said OET in a public notice Wednesday (http://bit.ly/1eSCCYY). Parties may participate in the trial by accessing Comsearch’s test facility at http://comsearch.whitespacedatabase.com, it said. Participants are encouraged to test features like the channel availability calculator, the multichannel video programming distributor receive site and the wireless microphone registration utility, it said. Registrations for MVPD receive sites and temporary broadcast auxiliary service links that are made during the trial period will be deleted by Comsearch after the trial, it said.
