摘要: A method and mobile transceiver for asset tracking which detects an abnormal antenna condition (such as damage or tampering which detects damage or tampering suspected damage or tampering) is provided. The mobile transceiver of the present disclosure comprises a cellular transceiver and a satellite receiver, each having an internal antenna and external antenna. The mobile transceiver detects an abnormal antenna condition, and can switch from the external antenna to the internal antenna, or vice versa, when an abnormal antenna condition is detected.
