Abstract

This paper describes a study of the performance improvement of Wireless LAN (WLAN) positioning system using spot information for pedestrian navigation systems. Spot information presents the names of landmarks, stores, rooms on walls, signboards or door plates. On the positioning procedure, a user first sends a spot name in front of him explicitly and BSSID and received signal strength information from WLAN implicitly to a positioning server. Then the server program specifies the user´s position using a spot information database and WLAN database. The spot information database includes the lists of spots´ names and their coordinates and the WLAN database includes the list of BSSIDs and received power strength data and their observed coordinates. This system must be registered a spot name by the user which want to get his location.
