Methods and Systems for Estimating Location of a Wireless Client Device

摘要

Methods and systems for estimating location of a wireless client device are disclosed. In some aspects, a receiver detects a plurality of wireless communication signals from a wireless client device using a plurality of receiver antennas, matches a received signal signature with one of a plurality of stored signatures, and estimates a location of the transmitting client device based on said match.

主权项

1. A method for estimating location of a wireless client device, comprising:
receiving, via at least a first and a second receive antenna configuration of a first receiver, respectively, at least a first and a second wireless signal associated with at least one transmission transmitted by a wireless client device from a first location; determining a first signature comprising at least a first and a second received-signal-strength-indication associated respectively with said at least first and second wireless signal; matching said first signature with at least one recorded signature taken from a bank of recorded signatures previously obtained via said at least first and second receive antenna configuration in conjunction with previous transmissions transmitted from known locations; and estimating said first location, using said matching, with at least one of said known locations that is associated, in said bank, with said at least one recorded signature.
