Ultra-wideband UWB is an emerging standard that is potentially capable of transmitting high-definition video between home-entertainment devices, such as set-top boxes, digital displays, camcorders, DVD players, digital video recorders, and digital cameras. At the moment, there are two camps, each backing a differing version of UWB, which is also known as 802.15.3.

The Motorola and XtremeSpectrum camp offers an approach to UWB, based on a variation of CDMA. The solution is an ultra wideband impulse radio that is designed to simultaneously provide high data rates, low power, low cost and low complexity.

Motorola plans to work closely with customers to embed the technology into an array of consumer products for demonstration by the end of this year.

Facing Motorola and XtremeSpectrum is a powerful coalition that includes Intel Corp [INTC] and Texas Instruments Inc [TXN]. This coalition is prompting a different technology as a basis for UWB.
