Abstract

We analyze the feasibility of boostrapping a location service through geocoded postal addresses rather than the common wardriving technique. A location service that contains the MAC addresses and geographic position of wireless LAN access points enables positioning services for WLAN devices and location-aware networking protocols. This work thus compares the accuracy of access point position estimates obtained based on RF signal strengths readings (wardriving) with the accuracy of the geocoded postal address. The results show similar accuracy for geocoding in comparison to typical wardriving studies, with significantly reduced effort if postal addresses of access point positions are known.
