Abstract:
The present invention relates to a method and system of locating a wireless device using received signal strengths. The method comprising: determining a plurality of multiple sets of transmit beamforming weights corresponding to a plurality of access points (APs) associated with a plurality of time slots; transmitting a signal using said each of said plurality of multiple sets of transmit beamforming weights associated with said plurality of time slots by said each access point (AP) of said plurality of access points (APs); and generating a plurality of received signal strengths corresponding to said plurality of time slots associated with said each of said plurality of multiple sets of transmit beamforming weights by said each access point (AP) of said plurality of access points (APs) at any location.

Claim (Index 9):
A method for locating a tag, the tag receiving beacon frame signals from a plurality n of access points (APs), each access point having a plurality p of transmit antennas, the tag and plurality of access points operative in the same frequency band, the method comprising:\n each of the access points transmitting a sequence of k beacon frames, each beacon frame transmitted in a sequence of timeslots, each of the k beacon frames transmitted using a unique beamforming matrix which is operative to adjust the transmit phase to the p antennas to form a radiation pattern which, combined with the radiation patterns of other access points, provides a unique map of an (x,y) coordinate space by signal strength during each timeslot of transmission; the tag operative to determine a received signal strength indication (RSSI) from at least two of the access points to determine a location of the tag in the (x,y) coordinate space.
