| Abstract: | A location technique based on reverse link is studied in this paper. In this technique, the mobile station is located by checking the time difference of signal from the mobile station to two base stations in CDMA cellular network. Through testing this location technique in practice, this paper analyzes the reasons of wireless location error and puts forward some considerations of factors when putting this technique into practice. By examination,this technique has a high precision of location. |
