UWB

Ultra-WideBand
A radio communications technique based on transmitting very-short-duration pulses, often of duration of only nanoseconds or less, whereby the occupied bandwidth goes to very large values. This allows UWB to deliver data rates in excess of 100 Mbit/s, while using a small amount of power and operating in the same bands as existing communications without producing significant interference. However UWB is not limited to wireless communication, UWB can also use mains-wiring, coaxial cable or twisted-pair cables to communicate - with potential to deliver data faster than 1 gigabit per second.

UWB is fundamentally different from all other radio frequency communications. It is unique in that it achieves wireless communications without using a sine-wave RF carrier. Instead it uses modulated high frequency low energy pulses of less than one nanosecond in duration.
