Abstract (en)
[origin: WO2020036756A1] An enterprise system configures access point devices at an enterprise location to communicate with a location determination system (140). The location determination system receives wireless signal attributes of user computing devices (110) broadcasting Wi-Fi signal data at the enterprise location from one or more access point devices (130). For a particular time window, the location determination system determines aggregated features of received wireless signal data across all access point devices, and classifies each of the user computing devices as moving or stationary by applying the wireless signal data to a model. For each of the user computing devices determined to be moving, the location determination system calculates a respective position of the user computing device based on the wireless signal data. For each of the user computing devices determined to be stationary, the location determination system does not calculate a respective position of the respective user computing device.
