Abstract
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.
