Google’s White Space Proposal


Complex, probably over the heads of our bureaucrats.


In a six-page letter to the Federal Communications Commission, Google promoted plans for the unlicensed and unused spectrum, called TV “white space,” and tried to allay fears about interfering with broadcasters and wireless microphone users. Google attorney Rick Whitt urged the FCC to adopt rules that would allow devices to utilize the white space, saying it is a precious resource that was being grossly underutilized.

“The unique qualities of the TV white space - unused spectrum, large amounts of bandwidth, and excellent propagation characteristics - offer a once-in-a-lifetime opportunity to provide ubiquitous wireless broadband access to all Americans,” Whitt wrote.

The letter was aimed…at addressing interference concerns about the use of the white space, concerns that have prevented approval of the use by federal regulators. The FCC, for example, held off approving the use of white space last year after tests found that devices using the spectrum either interfered with or failed to avoid TV signals…

By using “spectrum sensing” technology, developed by Motorola, and new protocols proposed by Google that ensure white space devices won’t disrupt TV signals, Whitt believes the spectrum can be used without conflicts. He also proposed a “safe harbor” for wireless microphones covering several channels that would prohibit white space devices from using that spectrum.

“We’d like to think we’re standing in the shoes of consumers,” Whitt said Monday. “What works well for us also works well for consumers so they can access not just us but anything they’d like from the Internet.”

The devices tested, last year, were surprisingly amateurish. Google’s wireless mic beacons are designed for GPS location - and would add about $10 cost.

Objections must be resolved - from consumers’ groups as well as the “impartial” National Association of Broadcasters.

Lots of discussion coming up. And an election smack in the middle.
