摘要

随着人们对定位技术的需求日益增长，人们希望室内定位系统简单易行。基于无线局域网的室内定位系统是室内定位技术的主要候选。传统的基于WLAN的系统在使用前需要高昂的安装成本或长时间的现场校准。本文介绍了基于无线局域网的简易室内定位系统WiPS的实现。WiPS在终端之间使用RSSI，避免了现场校准。我们做了一个叫做旗帜游戏的实验，在这个实验中，人们举起和放下每只手握的掌上电脑。WiPS决定每只手是向上还是向下。实验结果表明，WiPS平均在4.8秒内检测到PDA的运动

WiPS: Location and Motion Sensing Technique of IEEE 802.11 Devices

For increasing needs of positioning technology, easy and simple indoor positioning system is desired. Wireless LAN based positioning system is a major candidate of indoor positioning technology. Conventional WLAN based systems require high installation cost or long site calibration before use. In this paper, we describe the implementation of simple WLAN based indoor positioning system WiPS. WiPS uses RSSI between terminals to avoid site calibration. We perform an experiment called a flag game, in which the person raises and lowers the PDA held in each hand. WiPS determines each hand is up or down. As results of the experiment, WiPS detects the movement of PDA in 4.8 sec. on an average
