The ultra-wide band (also known as UWB or as digital wireless pulse) is a wireless technology for the transmission of large amounts of digital data over a wide spectrum of frequency bands with very little power for a short distance. Broadband radio can not only carry a large amount of data over a distance of up to 230 feet at very low power (less than 0.5 milliwatts), but also has the ability to carry signals through gates and other obstacles that tend to reflect signals to more limited bandwidths and higher power. The ultra-wideband can be compared to other Bluetooth wireless short-range technology, which is a standard for connecting handheld wireless devices with other similar devices and desktop computers.
The ultra wide band emits digital pulses that are timed very precisely in a carrier signal across a very wide spectrum (number of frequency channels) at the same time. The transmitter and receiver must be coordinated to send and receive pulses with an accuracy of billions of seconds. In any given frequency band that may already be in use, the ultra-wideband signal has less power than normal and anticipated background noise, so theoretically no interference is possible. Time Domain, a company that applies to use the technology, uses an IBM-made microchip to transmit 1.25 million bits per second, but says there is the potential for a data rate of billions of bits per second.
Application
Ultra broadband has two main types of application:
1) Radar applications, where the signal penetrates nearby surfaces but reflects more distant surfaces, allowing objects to be detected behind walls or other claddings.
2) Voice and data transmission using digital pulses, allowing a signal of very low power and relatively low cost to transport information at very high rates within a restricted range.
In the United States, the Federal Communications Commission approved the commercial use of the ultra - wide band on February 14, 2002.
