Abstract
Systems and techniques are provided for determining arrival and departure latency for WiFi devices. Reports may be received from WiFi access points in an environment. The reports include an indication of a connection to or disconnection from one of the WiFi access points, a time of the connection or disconnection, and an identifier of the one of the WiFi access points. Data including connect times and disconnect times may be generated from the reports. Sensor and device data may be received from one or more sensors or devices in the environment. Data indicating a length of an arrival latency and a length of a departure latency for the environment may be generated with a machine learning system, where the data including connect times and disconnect times and the sensor and device data is input to the machine learning system.
