The disclosure herein describes receiving wireless signal strength data and detecting movement of a computing device relative to wireless access points based thereon. The computing device receives a signal strength data stream based on a wireless signal from a wireless access point. A signal strength range is determined based on the signal strength data stream during a learning time period while the computing device is within a defined area. The signal strength range indicates that the computing device is within the defined area associated with the wireless access point. During a detection time period, signal strength values outside of the signal strength range are detected and, based on the detected values, a notification is provided that indicates the computing device has moved outside the defined area. The described movement detection method provides rapid detection of movements of a computing device using already-obtained data that does not rely on interaction with other devices.

Detecting movement of a computing device based on wireless access point signal strength data and adaptive thresholds

The disclosure generally relates to identifying a Bluetooth Low Energy (BTLE) enabled Wi-Fi network receiver and automatically connecting to the BTLE-enabled network receiver via a Wi-Fi signal without using a Wi-Fi scanning operation. In some aspects, an initial connection may be established between the network receiver and a BTLE-enabled device during which the Wi-Fi scanning operation of the device is disabled. Thereafter, the device may automatically detect the BTLE-enabled network receiver via BTLE signal and automatically connect to the network receiving using a Wi-Fi signal without using the Wi-Fi scanning operation. In this way, the battery life of the device may be conserved by disabling the Wi-Fi scanning operation. Although the electronic device may be within the Wi-Fi range of the network receiver, the device may not search for or connect to the network receiver if it is outside of the BTLE range of the network receiver.
