此文提出一种用射频标签RFID技术做定位以及导航的方法。使用标签反射能量（RSSI）来达到识别定位的目的。文章认为基站（阅读器）数目的增加，有利于定位精度的增加-An locating approach is proposed to find

the location and tracking using RFID technique based on

Received Signal Strength Indication (RSSI).It is found that the

error is reduced by increasing the number of base stations.
