Abstract:
1. A method of inferring whether a Wi-Fi enabled device is substantially stationary, comprising: receiving information from signals transmitted by at least one Wi-Fi access point and received by the Wi-Fi enabled device, the receiving occurring over time; measuring, during at least one amount of time, a first duration of time during which the Wi-Fi enabled device detects signals transmitted by the at least one Wi-Fi access point; inferring whether the Wi-Fi enabled device is substantially stationary based on the first duration of time during which signals from the at least one Wi-Fi access point were detected; and calculating a quality of estimation for the inference of whether the Wi-Fi enabled device is substantially stationary based on a number of Wi-Fi access points from which signals are received during the at least one amount of time.
