摘要：
This paper presents the design and implementation of a local positioning prototype. The prototype implements received signal power level based positioning on IEEE 802.11b Wireless LAN (WLAN) platform. In addition to a WLAN adapter, the prototype includes a host PC, which runs a positioning application. The application computes and displays position estimates oil the basis of measurements performed by the WLAN adapter. A signal propagation model and an extended Kalman filter are used for enhancing the position estimates. With the used WLAN hardware, the mean absolute error of positioning was measured to be 2.6 m.
