Method and apparatus for detecting an abnormal antenna condition
First Claim
1. A method of operating a mobile transceiver having a processor, a wireless transceiver, an internal antenna and an external antenna each coupled to the wireless transceiver via a switch, the method comprising:
- switching an active antenna for the wireless transceiver to the external antenna;
determining whether an indication of an abnormal antenna condition of the external antenna has been detected; and
when an indication of an abnormal antenna condition of the external antenna has been detected,switching the active antenna for the wireless transceiver from the external antenna to the internal antenna, andsending, by the wireless transceiver via the internal antenna, a notification to an asset tracking service that an indication of an abnormal antenna condition of the external antenna has detected.

Abstract
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.

17. A method of operating a mobile transceiver having a processor, a wireless transceiver, an internal antenna and an external antenna each coupled to the wireless transceiver via a switch, wherein the mobile transceiver is a two-part, interconnected module, configured to be mounted to a door of a shipping container, wherein the interconnected module comprises an internal module to be located on an interior of the door of the shipping container and which carries the internal antenna, and an external module to be located on an exterior of the door of the shipping container and which carries the external antenna, the method comprising:
-
waking up the mobile transceiver after a period of inactivity; determining whether the door of the shipping container to which the mobile transceiver is mounted is open or closed; switching to the external antenna as an active antenna when the door of the shipping container to which the mobile transceiver is mounted is determined to be closed; and switching to the internal antenna as the active antenna when the door of the shipping container to which the mobile transceiver is mounted is determined to be open. - View Dependent Claims (18, 19)

20. A method of operating a mobile transceiver having a processor, a wireless transceiver, a plurality of antennas coupled to the wireless transceiver via a switch, the method comprising:
-
waking up the mobile transceiver after a period of inactivity, wherein mobile transceiver is a two-part, interconnected module configured to be mounted to a shipping container, wherein the interconnected module comprises an internal module to be located on an interior of the shipping container and which carries one or more internal antennae, and an external module to be located on an exterior of the shipping container and which carries one or more external antennae; measuring, via the wireless transceiver, a wireless signal using each of the plurality of antennas; selecting an antenna in the plurality of antennas in accordance with the measured wireless signals; and switching to the selected antenna as an active antenna of the wireless transceiver.
