Ultra Wideband (UWB)

Ultra Wideband or UWB is a 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 it 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 it 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.

Ultrawideband (UWB) technology offers great opportunities for short-range wireless multimedia networking. The usefulness of Ultra-Wideband will not just end with high-quality multimedia. It's raw high-speed performance will enable wireless to finally deliver on true device synchronization. Keeping your contacts, calendars, music and movies all in sync could be done so quickly users might begin to forget their content was originally on separate devices.

Unlike conventional wireless systems, which use narrowband modulated carrier waves to transmit information, Ultra-Wideband transmits over a wide swath of radio spectrum, using a series of very narrow and low-power pulses. The combination of broader spectrum, lower power and pulsed data means that Ultra-Wideband causes signi•cantly less interference than conventional narrowband radio solutions while safely coexisting with other wireless technologies on the market.


Ultra-Wideband allows consumers the hope of eliminating the maze of wires connecting electronic products in their home, including large screen displays, set-top boxes, speakers, televisions, digital video recorders, PCs/laptops, digital cameras, smartphones and more. Products that include Ultra-Wideband are expected to:

  • Build a home theater environment without cables

  • Share live multimedia content between televisions

  • Instantaneously transfer the images from a digital camera to another product

  • Quickly synchronize ultra high capacity digital audio players

  • Share wireless video between a computer and a separate monitor
