Abstract

The condition and/or integrity of goods is monitored while in transit using a local area network of tracked assets. Autonomous electronic sensors are situated in proximity to the cargo being shipped. These sensors communicate with an asset tracking unit affixed to the container for the goods via a mutter mode transceiver. The tracking unit has the ability to relay the cargo sensor data to the central station on demand, on exception, or on a predetermined schedule established by the central station. Communication between the cargo sensors and the tracking unit may be one-way (i.e., sensor to tracking unit) or two-way. Multiple sensors may communicate with each tracking unit.
