Tech Firms Push to Use TV Airwaves for Internet

A coalition of big technology companies wants to bring high-speed Internet access to consumers in a new way: over television airwaves. Key to the project is whether a device scheduled to be delivered to federal labs today lives up to its promise.

The coalition, which includes Microsoft and Google, wants regulators to allow idle TV channels, known as white space, to be used to beam the Internet into homes and offices. But the Federal Communications Commission first must be convinced that such traffic would not bleed outside its designated channels and interfere with existing broadcasts.
