Abstract
A database stores results of scans for wireless (e.g., Wi-Fi) access points, some of them directly associated with GPS coordinates. Mobile electronic devices detect access points, details of which are sent to the database. Contents of the database are analyzed for relations between the scanned access points and previously stored GPS coordinates. If a relation is found, the GPS coordinates are used for determining or estimating the location of the mobile device.
