FCC Begins Public Trial of Key Bridge TV Band Database System (3/5/13)
Tuesday, March 05, 2013 | Comments

The FCC will begin March 11 a 45-day public trial of Key Bridge Global’s TV band database system.

The limited trial is intended to allow the public to access and test Key Bridge’s database system to ensure that it correctly identifies channels available for unlicensed radio transmitting devices that operate in the TV band, properly registers radio transmitting facilities entitled to protection, and protects authorized services and registered facilities as specified in the rules.

“We encourage all interested parties to test the database and provide appropriate feedback to Key Bridge,” the FCC said.

The commission’s Part 15 rules require that unlicensed TV band devices contact an authorized database system to obtain a list of channels that are available for their operation 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 FCC. The database will then return a list of the channels available for operation by a device at its reported location.

Each database is subject to a public trial period of not less than 45 days to ensure that the database is providing accurate results before it can be made available for regular public use. Interested parties can file comments or reply comments on the trial at any time during and after the trial period.

The commission began a similar trial of Google’s TV band database system March 4.
