TRACKING DEVICE THAT CONSERVES POWER USING A SLEEP MODE WHEN PROXIMATE TO AN ANCHOR BEACON

摘要

A method for tracking objects in a way that conserves power resources. The method can establish a designed range defining a safe area based upon the broadcast signal of an anchor beacon. When the tracking device is within the designed range, the tracking device can be placed in a mode of low power consumption. Should the tracking device move outside of the designated range, then the tracking device can be placed in mode for active tracking. The level of power consumption can be achieved by only enabling a WAN transceiver in the active tracking mode.
