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 24):
A system for a tag receiver determining a tag receiver location from beacon frames received by the tag receiver, the system comprising:\n a plurality of access points, each access point transmitting a repeating sequence of beacon frames, each one of k beacon frames in a succession of k periodic timeslots, each access point having a plurality p of antennas, the plurality p of antennas coupled to a transmitter through a beamsteering matrix having k values in a succession, the beamsteering matrix modifying the transmit amplitude and phase for each antenna using a coefficient having a real and imaginary part for each of the k timeslots; the tag and access points operative in the same frequency band; the tag receiver associating a received signal strength indication (RSSI) from each of the received beacon frames, establishing a fingerprint of RSSIs for each access point and sequence of beacon frames, and finding a closest match to a location from the RSSI fingerprint.
