超宽带（UWB无线技术）以前一直限于军事雷达、灾害救援搜索等通信设备使用。其特点是发送输出功率非常小，但所使用的带宽却高达几千兆赫兹，最大数据传输速度可达每秒几千兆比特，耗电量仅为几百微瓦～几十毫瓦，是原有系统耗电量的１／１０～１／１００。这项技术利用短脉冲 UWB (UWB wireless technology) has previously been limited to military radar, disaster rescue search and other communications equipment. Its characteristic is to send the output power is very small, but the bandwidth used is up to several gigahertz, the maximum data transfer speed up to several gigabits per second, power consumption is only a few hundred micro-watts ~ tens of milliwatts, is The original system power consumption 1/10 ~ 1/100. This technique makes use of short pulses
