Abstract
Techniques for determining movement of a device away from a preferred location which provide notification. An example method includes receiving a signal from a beacon, determining a measure of a characteristic of the signal, performing a comparison of the measure of the characteristic to a predetermined threshold which is based upon a distance from the preferred location, determining that the device has moved at least the distance from the preferred location based upon the comparison, and issuing an alert.
