Location Tracking
First Claim
1. A method of tracking a wireless device, the method comprising:
- receiving signal strength data for each of a plurality of access points;
comparing the signal strength data from the plurality of access points to identify an anchor access point having a highest signal strength;
comparing remaining signal strength data from the plurality of access points to a threshold signal strength to identify at least one attractor access point;
accessing a memory for locations of the anchor access point and the at least one attractor access point;
calculating a pull point along a line from the anchor access point to the at least one attractor access point; and
estimating a location of the wireless device as an average of the pull point and the location of the anchor access point.

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.

10. An apparatus for determining the location of a wireless device, the apparatus comprising:
-
a memory configured to store identities and locations for a plurality of access points; a communication interface configured to receive signal strength data for each of the plurality of access points; a controller configured to compare the signal strength data for the plurality of access points to identify an anchor access point and an attractor access point and configured to determine a location of the wireless device as an average of the location of the anchor access point and a pull point along a line from the anchor access point to the attractor access point, wherein the pull point is defined by a relative signal strength of the attractor access point. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A non-transitory computer readable medium configured to store a computer program configured to perform a method for location tracking of a wireless device, the method comprising:
-
receiving a signal strength value for each of 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; comparing the signal strength data of the plurality of communication beacons except the anchor to a threshold signal strength; if none of the signal strength data of the plurality of communication beacons except the anchor is greater than the threshold signal strength, estimating a location of the wireless device based on location data of the anchor; and if any of the signal strength data of the plurality of communication beacons except the anchor is greater than the threshold signal strength, then; designating at least one of the communication beacons, except the anchor, having signal strength data greater than the threshold signal strength as an attractor; calculating location data for a pull point along a line from the anchor to the attractor; and estimating a location of the wireless device as an average of the location data of the pull point and the location data of the anchor. - View Dependent Claims (18, 19, 20)
