Google co-founder Larry Page made a rare trip to Washington this week. No, he wasn't lobbying for net neutrality or being grilled about Internet censorship in China. It was all about the white spaces -- and Google's growing fixation with wireless communications.

With opposition mounting, Page came to bolster Google's push to gain public access to these white spaces, slivers of wireless spectrum between the broadcast channels used by TV stations. . .

During his May 22 speech to the New America Foundation, a think tank where Google CEO Eric Schmidt is chairman-elect, Page used a wireless microphone to downplay interference concerns. "I don't think there's any technical credence to this at all," he said.

Page also argued that unlicensed white spaces offer a way for the U.S. to catch up with the rest of the world in broadband access. For the second year running, the U.S. ranked 15th among the 30 members of the Organization for Economic Cooperation & Development in terms of broadband availability, a recent survey found [BusinessWeek.com, 5/22/08]. Today, 10% of Americans still don't have access to DSL or cable broadband, according to consultancy Parks Associates.

Google and others also see white spaces as a way to reignite interest in municipal Wi-Fi networks, many of which are struggling or even being turned off due to financial and service-quality problems. Because the white-space spectrum is more robust, networks using those frequencies would require a fourth to a fifth as many Wi-Fi transmitters to cover an area, according to Michael Calabrese, vice-president of the New America Foundation. Thus, network construction would cost less, while the wireless connections would be speedier.

Should white spaces be approved for unlicensed use, Page hinted, Google might even build some networks for cities with its own funds. "We have money to invest," he said. "We'd probably do it if we could do it on a reasonable scale." Google currently operates a Wi-Fi network in Mountain View, Calif., used by 40,000 people. . .
