The Ultra Wideband Working Group (UWBWG) was founded in response to interest voiced by the UWB Community at the UWB Communications Workshop in 1998, as well as a result of the FCC's NOI on UWB. Members will be actively involved in setting industry standards, and voting on issues related to technology deployment.

Adapted from the FCC's NPRM and NOI for UWB devices can be used for precise measurement of distances or locations and for obtaining the images of objects buried under ground or behind surfaces. UWB devices can also be used for wireless communications, particularly for short-range high-speed data transmissions suitable for broadband access to the Internet. UWB radio systems typically employ pulse modulation whereby extremely narrow pulses are modulated and emitted to convey or receive information. The emission bandwidths generally exceed one gigahertz. In some cases, "impulse" transmitters are employed where the pulses do not modulate a carrier. Instead, the radio frequency emissions generated by the pulses are applied to an antenna, the resonant frequency of which determines the center frequency of the radiated emission. The bandwidth characteristics of the antenna will act as a low-pass filter, further affecting the shape of the radiated signal.
