Abstract :
This paper presents the design and implementation of a WLAN based system for locating and tracking receivers inside buildings. It utilizes the WiFi access points existing in most modern office buildings, and is able to track multiple objects simultaneously. Experimental result shows that it provides a locating accuracy of about 5 m under indoor environment.
