In endorsing the technology, the Federal Communications Commission said ultra-wideband (UWB) devices "appear to be able to operate on spectrum already occupied by existing radio services without causing interference." Regulators said the technology could benefit public safety, consumers and business while permitting efficient use of scare spectrum.

The FCC said it would seek comments on its proposal to forego licensing of UWB technology. Potential applications include short-range, high-speed data communications suitable for broadband access to the Internet and radar imaging of buried or obstructed objects.

Interference test results are due to be submitted to the Commission by Oct. 30.
