This document specifies short-range wireless active communication between two active IoT/telematic hardware items, such as a gateway device and/or a sensor.

NOTE            Active hardware item in this document refers to devices and sensors, which have capacity to record and transmit measurements, i.e. data, without external activation through extra accessories, e.g. readers or scanners.

The application of such communications is based on equipment and container type. This document covers the following:

—    

wireless technology choices for wireless communication involving active hardware items, i.e. sensor to device communication;

—    

critical design factors of containers and hardware items intended to be used within one container environment;

—    

parameters for open protocol communication and possible applications (use cases).

This document does not define installation locations for devices and sensors; however, it is expected that the hardware items are installed on or in the container, based on the following considerations:

—    

existing regulations and standards;

—    

container design, and specification of the material it is made of;

—    

best possible connection, which enables interoperable communication between sensor and device;

—    

cargo and personnel safety.

Due to the pace of technology development, the number of connected sensors to one gateway device are not defined in this document. This document assumes that at least one sensor can be connected to at least one gateway device wirelessly.
