1. A method for monitoring the status of a container for transporting goods, wherein the container includes sensors, the method comprising:

  • a) receiving data at a processing system within the container from at least one sensor within the container;

    b) implementing a controller within the processing system for comparing the received sensor data against a predetermined condition stored in a memory of the processing system;

    c) initiating a message from the controller in response to comparison between the received sensor data and the predetermined-condition related to the measured sensor data;

    d) transmitting the initiated message as an RF signal from within the container to a satellite transceiver element outside the container, thereby initiating unprompted communication from inside of the container, wherein the RF signal is transmitted outside of the container via a passive antenna system;

    e) wherein the transmitted RF signal comprises profile information stored in memory of the processing system, and the transmitted RF signal is scanned for such profile information upon receipt at the satellite transceiver element prior to any further processing.
