Reducing Risk of Cross Commissioning in a Radio Network
First Claim
1. A method for preventing inadvertent pairing of a wireless sensor node with a coordinator node in a wireless personal area network (WPAN) incorporated into a refrigerated container system, the method comprising:
- extracting a property value from a pairing request message provided by the sensor device to the coordinator;
comparing the property value to expected property values for sensor devices in the wireless personal area network; and
conditionally allowing, by the coordinator, pairing with the sensor based upon the comparing step.

Abstract
A refrigerated container system is described that includes a wireless personal area network (WPAN) including a plurality of wireless sensor nodes and a coordinator node through which the sensors provide sensor data to a controller for the refrigerated container system. The wireless sensors and the coordinator incorporate a variety of features that ensure efficient utilization of battery life by preventing unintended pairing of sensors with other WPANs and excessive sensor signal processing arising from door chatter. Finally, pairing is performed without pressing a button on the wireless door sensor. Instead, the sensor'"'"'s magnetic reed switch is enlisted to detect swiping of a magnet by a user to enter a pairing mode.
