The FCC today announced the public testing of a new TV White Spaces database system. Starting on September 19, 2011, the FCC's Office of Engineering and Technology will open a 45-day window to allow the public to try out the TV Band Database developed by one of the potential TV White Spaces database managers. If approved, the Database will be used by white space devices to find available frequencies and avoid interfering with authorized services and registered facilities. As we have written about previously (here) the Commission has adopted new rules to allow unlicensed devices to operate in the television spectrum, but such operations must protect incumbent users. Accordingly, as part of those rules, the Commission has required the development and use of a database, which TV band devices will be required to access periodically in order to determine available frequencies and adjust their operation. As we discussed here, the Commission has tentatively selected a number of parties to serve as database managers to develop and maintain such TV white spaces databases. With this upcoming public trial, interested parties will now have a chance to test the database system developed by one such potential database manager. As part of its authorization process, each interested database manager will be subject to a similar trial period of no less than 45 days.....
