Ultra Wideband: Ultra-Wideband (UWB) technology is a power-efficient short-range radio technology which is best suited to WPANs (Wireless Personal Area Networks) UWB complements existing long range radio technologies like Wi-Fi and WiMAX and provides high bandwidth solution for multiple digital video and audio streams. A
UWB transmitter sends billions of pulses across a very wide frequency spectrum that is several GHz in bandwidth.  The pulses are then translated into data by the corresponding receiver by listening to the familiar pulse sequence that is sent by the transmitter. UWB is characterised by larger spectrum, low power consumption and pulsed data. This results in improved speed and a considerably reduced interference with other Wireless spectra.
