IP: What is UWB?

[David Farber <dave () farber net>]

It is:

One technology currently being examined is ultra wide band (UWB) radio, 
which sends individual pulses instead of continuous signals, and at a power 
level close to that of electrical noise. The advantage of continuous 
signals is that they are relatively easy to detect, whereas picking a 
single pulse of radio energy out of the background is very difficult ­ 
unless it is so powerful as to swamp everything else.
