Abstract
A method for communication includes identifying a media access control (MAC) address of a mobile station of interest. Independently of receiving any probe request frame from the mobile station, a probe response frame addressed to the identified MAC address is transmitted over a wireless local area network (WLAN). An acknowledgment of the probe response frame is received from the mobile station and is used in ascertaining a location of the mobile station.
Claims25
A method for communication, comprising:
- identifying a media access control (MAC) address of a mobile station of interest;
- independently of receiving any probe request frame from the mobile station, transmitting a probe response frame addressed to the identified MAC address over a wireless local area network (WLAN);
- receiving an acknowledgment of the probe response frame from the mobile station;
- and
- ascertaining a location of the mobile station responsively to the received acknowledgment.

Apparatus for communication, comprising:
- a wireless transceiver, which is configured to identify a media access control (MAC) address of a mobile station of interest and, independently of receiving any probe request frame from the mobile station, to transmit a probe response frame addressed to the identified MAC address over a wireless local area network (WLAN), and to receive an acknowledgment from the mobile station of the probe response frame;
- and
- a processor, which is configured to ascertain a location of the mobile station responsively to the received acknowledgment.
A communication system, comprising:
- a plurality of wireless tags, which are configured to be fixed to respective items, each tag having a respective media access control (MAC) address that is defined for communication over a wireless local area network (WLAN);
- a wireless transceiver, which is configured to identify the respective MAC address of a tag that is fixed to an item of interest and, independently of receiving any probe request frame from the transceiver, to transmit a probe response frame addressed to the identified MAC address over the WLAN, and to receive an acknowledgment of the probe response frame from the tag;
- and
- a processor, which is configured to ascertain a location of the item of interest responsively to the received acknowledgment.
