UWB can be realized hundreds of by transmitting the signal of extremely low power on wider frequency spectrum in the range of 10 meters or so
The message transmission rate of Mbit/s to several Gbit/s.UWB has that strong anti-interference performance, transmission rate are high, very bandwidth is wide, consumption is electric
The many advantages such as energy is small, transmission power is small, are mainly used in indoor communications, high-speed wireless LAN, home network, wireless phone, peace
The fields such as full inspection survey, position finding, radar.
UWB technology is initially to be mainly used for Radar Technology field in early days by as military radar technological development.2002
2 months, U.S. FCC had approved UWB technology for civilian, and the developing steps of UWB start gradually to accelerate.
Different from bluetooth and the relatively narrow conventional wireless system of WLAN equiband, UWB can send a series of on wideband
Very narrow is low powder pulsed.Wider frequency spectrum, lower power, chopping data, it is meant that interference caused by UWB, which is less than, to be passed
The narrowband wireless solution of system, and can provide and wired performance to compare favourably in wireless environment indoors.UWB has following
Feature:
Strong anti-interference performance.UWB uses hop-time spread spectrum signal, and system has biggish processing gain, will be micro- in transmitting

It is not interfere with each other with being worked at the same time with narrow-band communication system.This was opened a kind of new in today of frequency resource growing tension
Time-domain radio resource.
It is small to consume electric energy.Under normal conditions, wireless communication system needs continuous transmitting carrier wave in communication, therefore to consume
Certain electric energy.And UWB does not use carrier wave, only issues momentary pulse electric wave, that is, directly send by 0 and 1, and
Pulse radio is just sent when needing, so consumption electric energy is small.
Good confidentiality.UWB confidentiality shows both ways.It on the one hand is using hop-time spread spectrum, the only known hair of receiver
Transmitting data can be just solved when sending end spreading code；Another aspect is that the transmission power spectrum density of system is extremely low, with traditional reception
Machine can not receive.
