摘　　要：随着现代社会科技水平的不断提高和通信技术的愈加完善,定位技术受到了用户越来越多的关注。WiFi定位技术具有在室内获取便利、覆盖范围广、信息传输速度快和搭建成本低廉等优点而得到了广泛的应用。提出了一种基于WiFi技术的位置指纹定位算法,称为快速定位算法,极大地提高了计算效率,并且仍然能够保持室内定位的精确性。基于此,设计并实现了应用于Android终端的室内定位系统。With the continuous improvement of the level of science and technology in modern society and the increasing perfection of communication technology, positioning technology has been paid more and more attention. WiFi positioning technology has the advantages of convenient access in the room, wide coverage, high information transmission speed and low building cost, so it has been widely used. A location fingerprint positioning algorithm based on WiFi technology, namely fast positioning algorithm, is proposed, which greatly improves the computational efficiency, and can still maintain the accuracy of indoor positioning. Based on this, the indoor positioning system applied to the Android terminal is designed and implemented.
