Patent ID: 8089371

Claim:
A wireless device locating apparatus, the apparatus comprising: a communication interface configured to receive signal strength values including a first set of signal strength values for an associated wireless device detected at a first plurality of radio receivers disposed in a first region and a second set of signal strength values for the associated wireless device detected at a second plurality of radio receivers disposed in a second region; and, determination logic operatively connected with the communication interface and being configured to determine a region that the associated wireless device is located, the determination logic including: a first weighting portion selectively weighting the signal strength values of the first set of signal strength values with at least two different weight values as a first set of weighted signal strength values, and selectively weighting the signal strength values of the second set of signal strength values with at least two different weight values as a second set of weighted signal strength values; a first summing portion summing the first set of weighted signal strength values as a first weighted sum, and summing the second set of weighted signal strength values as a second weighted sum; and, an identifying portion identifying the region that the wireless device is located by a comparison of the first weighted sum with the second weighted sum.
