What is UWB?

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. The basic concept is
to develop, transmit and receive
an extremely short duration burst
of radio frequency (RF) energy –
typically a few tens of
picoseconds (trillionths of a
second) to a few nanoseconds
(billionths of a second) in
duration.

Frequency range occupied is more
than 500 MHz or fractional bandwidth
is greater than 20%.
