Google leader sees green in white space

Google co-founder Larry Page and Kevin Martin, chairman of the Federal Communications Commission, lauded this week's FCC vote to open up vacant broadcast spectrum for unlicensed use - a move, they said, that carries enormous potential. The new use of these "white spaces" could enhance people's lives in much the way that Wi-Fi has become indispensable for laptop and mobile device owners, they said Thursday at a wireless conference in San Jose. But it will take at least 18 months before devices are built to work on the spectrum.
