UWB Planet: FCC Says UWB Is Not a Threat to GPS

Oct 25, 2002, 20:07 (0 Talkback[s])

The Federal Communications Commission (FCC) this week released a report that indicates that ultrawideband (UWB) is no more of an interference threat to the Global Positioning System (GPS) than a laptop or hairdryer.

In February, the FCC approved the sale of UWB products in the United States, but established what it called "extremely conservative emissions limits" to assuage concerns about possible interference with GPS. Proponents of the technology, which is touted for its potential for short-range, high-speed data transmissions, have argued that the limits for UWB devices are inappropriate given the levels of radio noise emitted by other electric devices.

Unlike conventional radio systems, which operate within a relatively narrow bandwidth, UWB operates across a wide range of frequency spectrum by transmitting a series of extremely narrow (10-1000ps) and low power pulses. The commercial uses of the technology range from wireless networks (scalable from low to ultra high speeds) to remote sensing and tracking devices, and ground-penetrating radars.
