Ultra Wideband is a technology used for transmitting high bandwidth data, such as video or audio, over a wide spectrum of frequency bands, across short-ranges, using low-power.

This is done via the transmission of very short (measured in nanoseconds) digital pulses of energy. UWB can be applied to a variety of uses including ground or wall penetrating radar, used for example in search and rescue missions, in industry for monitoring products during manufacture and in the home for video games, digital cameras and home theatre.

UWB radio transmissions can legally operate in the frequency range from 3.1 GHz up to 10.6 GHz.
