Abstract
A wireless access point in a wireless network that may be adapted to transmit location data indicating its location to other devices within range, including other wireless access points and client devices. The location data may be embedded in a control message or announcement transmission transmitted by the wireless access point. In terms of the Open Systems Interconnect (OSI) layered model of a network, layer 2 control messages, including beacons, probe responses, or other suitable transmissions may be used for control messages or announcement transmissions. The other wireless access points and client devices may receive the location data broadcast by the wireless access point without establishing a connection to the client device. Devices receiving the location data may use the received location data to determine their own locations, and may provide the determined locations to consumers of location data.
