DETERMINING LOCATION VIA WIRELESS ACCESS POINTS

摘要

Determining a location of a user device comprises a wireless computing system supported by an access point. The wireless computing system receives a signal from the user device. The system estimates a location of the user device based on RSSI and calculates a boundary around the estimated location. The wireless computing system selects a plurality of sections inside of the boundary and performs a coarse calculation of a location of the user device based on an angle of arrival of the received signal. The system determines sections of the plurality of sections that have results from the coarse calculation that are more likely to be a location of the user device. The system performs a fine calculation of the location based on the angle of arrival of the received signal within each of the sections. The system identifies a particular section as the location of the user device.

主权项

1. A method, comprising:
receiving, by at least one wireless computing system access point of a computing system, a wireless signal from a user computing device; calculating, using the computing system, a location estimate of the user computing device relative to the at least one wireless computing system access point and based on a signal strength of the signal received by the at least one wireless computing system access point; calculating, using the wireless computing system, a defined boundary encompassing the estimated location of the user computing device; dividing, using the one or more computing devices, an area inside the boundary into a plurality of sections; computing, using the computing system, a first calculation of a location of the user computing device within the area inside the defined boundary based on an angle of arrival of the signal received by the at least one wireless computing system access point; determining, using the computing system, one or more sections of the plurality of sections of the area inside the defined boundary that have results from the first calculation that are more likely than results for other sections to include an actual location of the user computing device; computing, using the computing system, a second calculation of a location of the user computing device based on the angle of arrival of the signal received by the at least one wireless computing system access point, the second calculation being performed for an area within each of the identified plurality of sections of the area inside the defined boundary that have results from the first calculation that are more likely than results for other sections to include an actual location of the user computing device; selecting, using the computing system, a particular section of the plurality of sections that has results from the second calculation that are most likely to be the actual location of the user computing device; and transmitting, using the computing system and to the user computing device, location data related to the identified particular section of the plurality of sections to indicate the actual location of the user computing device.
