Abstract
A tracking device has a first transceiver, a second transceiver, and control logic. The first transceiver can transmit a first tracking signal for locating the tracking device to mobile devices via a first network. The mobile devices provide the first tracking signal to a tracking server. The second transceiver can transmit a second tracking signal for locating the tracking device to the tracking server via a second network. The control logic can configure the tracking device in a first state in which the first transceiver transmits the first tracking signal, and the second transceiver is disabled and does not transmit the second tracking signal. In response to determining that the tracking device cannot connect to the tracking server via the first network, the control logic configures the tracking device in a second state in which the second transceiver is enabled and transmits the second tracking signal.
