Motorola Submits White Space Device for FCC Testing

Motorola has delivered and demonstrated a prototype white space device (WSD)—or, as Motorola calls it, a Cognitive Radio Device—to test whether it can sense, and thus avoid, interfering with DTV signals.

Motorola officials gave the device to FCC Office of Engineering and Technology staff at a meeting Nov. 15 and dropped off a two-page sheet of instructions for operating and testing the device. Motorola previously demonstrated a prototype device to FCC staff Aug. 30.

In an FCC filing, the company said the device uses a "geolocation database that is augmented by sensing algorithms" to determine which TV channels are available for use.
