MCADAMS / 02.27.2013 06:27PM FCC Opens Google White-Space Database for Public Trial 45-day period begins March 4 WASHINGTON - "The Federal Communications Commission's Office of Engineering and Technology announced that on March, 4 2013, it will commence a 45-day public trial of Google's TV-band database system. The trial is a public test run of the system to be used by unlicensed devices to identify unoccupied TV channels in the television broadcast frequency band. All those affected are encouraged to weigh in on the trial. Commission rules require that "unlicensed TV band devices contact an authorized database system to obtain a list of channels that are available for their operation-i.e., channels not occupied by authorized radio services-at their individual locations and must operate only on those channels. Such devices are required to provide their geographic location, by means of a secure Internet connection, to a TV band database system authorized by the Commission. The database will then return a list of the channels available for operation by a device at its reported location." Part of the authorization process is the 45-day trial. Telcordia of Piscataway, N.J., and Spectrum Bridge of Lake Mary, Fla., have both completed the trial phase and launched their white-space databases along the Eastern Seaboard in January. "OET has examined the Google database system's channel availability calculator and registration facilities and finds that these capabilities are ready for trial testing by the public," the commission's Public Notice said. Parties may participate in the trial by accessing Google's TV band database test facility at: https://www.google.org/spectrum/whitespace/. The website will provide a description of the trial, instructions for participation, details on use of the database system, access to the database's various capabilities, and a link for providing comments and other feedback to Google. The test facility will not be active before March 4."
