White space in the future of wireless broadband

It is high time that Asian spectrum managers started thinking about more efficient use this valuable resource.

Having missed the opportunity to include these provisions in the coming auction, the F.C.C. will have another chance this year to create cheaper wireless broadband services. Google and other technology companies, including Dell, Philips and Microsoft, are part of a group called the White Space Coalition that is asking the F.C.C. to open up the empty space between assigned TV channels to unlicensed users and devices.

The idea would work like this: In many areas, not all broadcast channels are in use. The unused channels are “white spaces” of high-quality spectrum that could be made available to local Internet service providers. Unlike the much higher frequency of Wi-Fi, television broadcast frequencies can travel for miles and penetrate walls, providing a much broader range for Internet service. Because the unused channels vary across the country, the group proposes that consumers be able to buy generic devices, like PC cards for Wi-Fi, that would search for open frequencies and connect to a service.
