The coalition, which includes Microsoft Corp., Google Inc., Dell
Inc. and others, wants the agency to open up unlicensed and unused
TV spectrum, also known as "white spaces," for broadband Internet
service.

However, TV broadcasters are unconvinced the device will work and
said if the new technology is approved it could also cause
problems with their federally mandated transition from analog to
digital signals in early 2009.

Does anyone know the true definition of these "white spaces"?

I suppose this would a sort of half-duplex scheme with the downlink
via the TV antenna and the uplink via telephone?

They think they can use little transmitters in everybody's house and
not interfere with your next door neighbor's digital TV.
