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.
Applications
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
