US 2022/0286805 A1 · LOCATING DEVICES WITHIN A PREMISES

Abstract

Methods and systems are disclosed for estimating locations of devices operating on a network (such as a wireless network) in a premises. Signal strength measurements of signals sent by the devices may be used to estimate locations of the devices within the premises as well as to estimate anchor points where signals are received from the devices. The devices may be shown on a map of the premises. The anchor points may be shown on a map of the premises. A method may be implemented iteratively to estimate the device locations as well as the locations of the anchor points. Estimated locations of devices and/or anchor points may be used to estimate a location of a device misplaced or lost in the premises.

Claims20

Dependent claims

A method comprising:

determining, for a first location in a premises, a first signal strength associated with a first signal sent by a first device;
determining, for a second location in the premises, a second signal strength associated with a second signal sent by the first device;
determining, based at least in part on the first signal strength and the second signal strength, an estimation of the first location and an estimation of the second location;
and
determining, based on the estimation of the first location and the estimation of the second location, an estimation of a location of the first device.
