  • On the Android platform, we design and use WiFi signal strength characteristics to locate. The location system in this paper is made up of Android client, Tomecat server and MySQL database.Based on the RSSI WiFi fingerprint positioning in the offline establishment of the fingerprint database by the sampling distance of the impact, the sampling distance can inevitably affect the accuracy of fingerprint positioning. In order to explore the effect of sampling pitch on WiFi fingerprint positioning, the experiment is carried out in the classroom. Select a different sampling interval to carry out WiFi fingerprint positioning, and we measure the positioning accuracy and timeliness as the positioning result. Experiment results show that: in indoor environment, the sampling interval is 3 m,the timeliness is higher and the positioning accuracy can meet the requirements.
