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 14):
A system for generating a plurality of received signal strength indication (RSSI) for use by a receiver determining its position with respect to a plurality of access points, said system comprising:\n a plurality of access points, wherein each access point is adapted to transmit a sequence of k beacon frames, each beacon frame having a modified phase applied to each of a plurality of transmit antennas, the modified phase applied to each antenna by multiplying the beacon frame with a beamsteering matrix comprising real and imaginary coefficients; the access points and the receiver operative in a single frequency band; each AP operative to transmit its respective sequence of k beacon frames during a unique timeslot; a receiving station receiving each plurality of beacon frame sequences from the plurality of access points, the receiving station associating a receive signal strength indication (RSSI) with each received beacon frame; a location resolver operative to compare each RSSI with a fingerprint map for best match to an (x,y) location to resolve a location of the receiver.
