Considerable promise for Internet access in TV "white spaces" [PersonRank 10]

Besides 700 MHz spectrum auction, but there's another spectrum-related proceeding at the FCC that also holds promise for expanding Internet access to more Americans: opening unused “white spaces” in the television spectrum bands for broadband service. These unused channels will become even more useful for broadband applications once broadcasters vacate some of this spectrum as part of the February 2009 digital television transition.

Coveted bits of the radio spectrum called "white spaces" – unused areas of spectrum wedged between licensed TV channels – may soon be freed up by the Federal Communications Commission. Right now no broadband devices are allowed to use these parts of the spectrum, but the FCC is considering whether to let companies sell FCC-certified wireless devices that would be used without an exclusive broadcast license in these slivers of bandwidth. Such white-space devices (WSDs) would be low-power and so would emit signals over very small geographic areas. White space within the TV band is unlicensed, like WiFi, but is physically better suited than WiFi for broadband transmission.
