DETERMINING A DESIGNATED WIRELESS DEVICE LACKS A FIXED GEOGRAPHIC LOCATION AND USING THE DETERMINATION TO IMPROVE LOCATION ESTIMATES

摘要

In one embodiment, a system determines a designated wireless device lacks a fixed geographic location, and uses the determination that the designated wireless device lacks a fixed geographic location to improve location estimates. The system determines one or more neighboring wireless devices have relationships with the designated wireless device, wherein a relationship is established when wireless signals from a neighboring wireless device and the designated wireless device are detected by a same receiver. A measure of likelihood is calculated that the designated wireless device lacks a fixed geographic location based at least in part on a number of the relationships or a duration of the relationships. Based on the measure of likelihood, the designated wireless device is excluded from being used in the wireless positioning system as a beacon for estimating the location of a client device.

主权项

1. A method of determining that a designated wireless device lacks a fixed geographic location, and using the determination that the designated wireless device lacks a fixed geographic location to improve location estimates, the method comprising:
determining, by a wireless positioning system, one or more neighboring wireless devices having relationships with the designated wireless device, wherein a relationship is established when wireless signals from a neighboring wireless device and the designated wireless device are detected by a same receiver; calculating a measure of likelihood that the designated wireless device lacks a fixed geographic location based at least in part on a number of the relationships or a duration of the relationships; and based on the measure of likelihood, excluding the designated wireless device from being used in the wireless positioning system as a beacon for estimating the location of a client device.
