Entering a low power state on the beacon decreases the energy requirements. An alert is transmitted from the beacon via a communication network and includes a location message indicating the location of the beacon. The beacons location is calculated using network-based, SIM-based or device-based methods. Using location 10 determination only after failing to receive the subsequent response and when preparing to transmit the alert prevents accurate location determination being performed when it is not necessary to determine the pet is safe and therefore decreases the energy requirements.
