Abstract

One or more systems, devices, and/or methods for tracking a wireless device are disclosed. For example, a method includes receiving signal strength data for each of a plurality of access points. The signal strength data from the plurality of access points is compared to identify an anchor access point having a highest signal strength. Remaining signal strength data from the plurality of access points are compared to a threshold signal strength to identify at least one attractor access point. A memory is accessed for locations of the anchor access point and the at least one attractor access point. A pull point is calculated along a line from the anchor access point to the at least one attractor access point. A location of the wireless device is estimated as an average of the pull point and the location of the anchor access point.

First claim

I claim:

1. A method comprising:
receiving signal strength data for a plurality of communication beacons;
comparing the signal strength data to identify an anchor having a highest signal strength of the plurality of communication beacons;
receiving data indicative of a location of the anchor;
comparing the signal strength data of the plurality of communication beacons to a threshold signal strength; and
when none of the signal strength data of the plurality of communicatio…
