Patent ID: 8169300

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, wherein the second strongest signal strength values of the first and second set of signal strength values are weighted higher than other signal strength values of the first and second set of 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.
