ABSTRACT:
A wireless network permits wireless devices to determine their own location and receive location-based services. The network includes a communication server coupled to a plurality of access points and at least one mobile wireless device that wirelessly communicates through the access points. Each wireless device includes a location table through which the wireless device can determine its physical location. The location table includes the physical location of the various access points indexed by their network addresses. When the wireless device communicates with an access point, the access point provides the wireless device its address. The wireless device uses the address of the access point as an index into the location table to determine its own location based on the location of the access point. Once the wireless device has determined its own physical location, it requests location-based services from or through the communication server.
