摘要

Methods and systems for mitigating the impact of beamforming on the accuracy of Wi-Fi based location tracking of client devices. An embodiment takes the form of a process that includes (a) obtaining a plurality of received signal strength indicator (RSSI) values respectively associated with frames in a plurality of frames that were (i) received by various access points in a plurality of access points and (ii) transmitted by a client device that is connected to a first access point in the plurality of access points; (b) segmenting the access points in the plurality of access points into (i) a beamforming-path set of one or more access points and (ii) a non-beamforming-path set of one or more access points; (c) identifying a location-determination subset of the obtained RSSI values; and (d) determining a location of the client device using the identified location-determination subset of the obtained RSSI values.
