With the widespread and deployment of wireless LAN, the RSSI signal strength fingerprint location technology, without needing to add extra hardware in indoor environment, becomes hot research. But large fluctuations signal will cause errors in location. This paper proposes a zoning RSSI location method, using Wi-Fi signal strength to divide regions, and then uses signal fingerprint database matching mobile device aera. Finally, the experiment shows that the 25th, 50th and 70th percentile values of the location distance error are 1.25 m, 2.25 m and 4.75 meter, which can reduce signal fluctuations caused by the location errors.
