Abstract
A method of tracking objects uses an anchor beacon that can emit a broadcast over a range that is detectable by an object tracking device. The object tracking device can automatically detect a presence or absence of the broadcast. When the broadcast is present, the object tracking device can take no action. When the broadcast is absent, the object tracking device can determine a current location for the object tracking device and can convey an OTA communication to a tracking server. The OTA communication can indicate the absence of the broadcast and can also including the current location. The tracking server can selectively send a notification to a previously designated communication device to notify a user that the object tracking device is outside the range.
