Ultra-Wideband (UWB) Technology

Ultra-wideband (UWB) permits short-range, high-bandwidth communications at very low energy levels by using a large portion of the radio spectrum. UWB has traditionally been used for radar imaging with pulsed signals. Today’s UWB systems for wireless connectivity communications are based on an OFDM system structure. The most important UWB communications system, promoted by WiMedia®, also uses a multiband OFDM (MB-OFDM) structure, which is implemented in the ECMA-368 standard. This standard is optimized for low power consumption at high data rates. WiMedia® UWB technology has been selected by the Bluetooth SIG, Inc. for high-speed Bluetooth® and by the USB Implementers Forum for wireless USB.
