Abstract
Techniques are presented to determine a location of a wireless client device operating in a wireless local area network. A beacon report request action frame is sent to a wireless client device, where the request frame is configured to cause the wireless client device to transmit a broadcast probe request frame. A beacon report response message is received from the wireless client device and includes one or more probe response frames transmitted by one or more wireless access points that receive the broadcast probe request frame. The wireless client device location is determined based in part on signal strength information in the probe response frames sent by the one or more wireless access points and which signal strength information indicates the signal strength observed by the one or more wireless access points with respect to the broadcast probe request frame transmitted by the wireless client device.
