	ultra wideband - a Whatis.com definition
		Ultra wideband (also known as UWB or as digital pulse wireless) is a wireless technology for transmitting large amounts of digital data over a wide spectrum of frequency bands with very low power for a short distance.
		Ultra wideband can be compared with another short-distance wireless technology, Bluetooth, which is a standard for connecting handheld wireless devices with other similar devices and with desktop computers.
		Ultra wideband broadcasts digital pulses that are timed very precisely on a carrier signal across a very wide spectrum (number of frequency channels) at the same time.

	Ultra-wideband - Wikipedia, the free encyclopedia
		National jurisdictions around the globe are expected to act on national regulations for UWB very soon.
		Ultra Wideband was traditionally accepted as impulse radio, but the FCC and ITU-R now define UWB in terms of a transmission from an antenna for which the emitted signal bandwidth exceeds the lesser of 500 MHz or 20% bandwidth.
		Thus, pulse-based systems—wherein each transmitted pulse instantaneously occupies a UWB bandwidth, or an aggregation of at least 500 MHz worth of narrow band carriers, for example in orthogonal frequency-division multiplexing (OFDM) fashion—can gain access to the UWB spectrum under the rules.

	A Brief History of Ultra Wideband (Site not responding. Last check: 2007-10-23)
		The origin of ultra wideband (UWB) technology stems from work in time-domain electromagnetics begun in 1962 to fully describe the transient behavior of a certain class of microwave networks through their characteristic impulse response (Ross 1963, 1966).
		In attempting to understand the wideband properties of this network, efforts were made to reference the properties of the four port interconnection of quarter wave TEM mode lines which formed the branch line coupler.
		The term: Ultra Wideband or UWB signals has come to signify a number of synonymous terms such as: impulse, carrier-free, baseband, time domain, nonsinusoidal, orthogonal function and large-relative-bandwidth radio/radar signals.

	Ultra Wideband Frequently Asked Questions (Site not responding. Last check: 2007-10-23)
		First of all, the term "ultra wideband" is a relatively new term to describe a technology which had been known since the early 1960’s as "carrier-free", "baseband" or "impulse" technology.
		This is due to the fact that any impulse or white Gaussian noise excitation of the wideband receiver front end produces a received waveform having characteristics very similar to those of the transmitted waveform.
		Ultra Wideband technology has been the technology of choice for these applications, and the Task Group met in San Francisco the week of 21 July 2003 to down select from an original set of 31 PHY proposals.

	ON World - Ultra wideband: Bluetooth's Biggest Challenge
		"The major advantages of ultra wideband technology (UWB) are that it is an intrinsically non-interfering technology that requires little power while achieving 100s of Megabit per second data rates with built-in quality of service," says ON World's Director of Research Mareca Hatler.
		Long term, however, there is no reason why UWB cannot be used for ultra low power applications and its unique characteristics will quickly establish its superiority over existing technologies such as Bluetooth, Wi-Fi and the in-progress Zigbee standard for wireless sensor networking.
		Contrary to the opponents' beliefs and much hasty media coverage, Hatler notes that UWB is very unlikely to interfere with other radio frequency technologies while being quite robust from interference from other technologies.
