1. A method for determining a location of a wireless tracking device, the method comprising:
- determining whether the wireless tracking device is in communication range of an alarm panel in a network of alarm panels by evaluating availability of an incoming signal from the alarm panel on a short-range radio of the wireless tracking device;
if the wireless tracking device is determined to be in the communication range of the alarm panel, then determining the location of the wireless tracking device based on communication with the alarm panel,wherein the step of determining the location of the wireless tracking device based on communication with the alarm panel when the wireless tacking device is in the communication range of the alarm panel comprises;
generating and transmitting a query via the short-range radio of the wireless tracking device to the alarm panel for an identification of the alarm panel;
responsive to the query, receiving via the short-range radio of the wireless tracking device, an alarm panel code associated with the alarm panel;
correlating, at the wireless tracking device, the alarm panel code of the alarm panel with a location of the alarm panel using a data table stored in the memory of the wireless tracking device, wherein the data table comprises a list of alarm panel codes associated with alarm panels of the network of alarm panels and locations of the alarm panels;
determining the location of the wireless tracking device as the location of the alarm panel; and
transmitting the location of the wireless tracking device via a cellular radio of the wireless tracking device; and
if the wireless tracking device is determined to be out of communication range of the alarm panel, then determining location of the wireless tracking device using a location detector that the wireless tracking device comprises.

Abstract
A wireless tracking device can operate in two or more modes in connection with determining location of the wireless tracking device. In one mode, the wireless tracking device can determine location by establishing communication with an alarm panel using a short-range transceiver. The alarm panel can have a location that is known at the alarm panel or at a remote server, for example. In another mode, the wireless tracking device can utilize a location detector, such as a GPS receiver or a short-range receiver, to determine location of the wireless tracking device.
