LoRa®-based devices connected to a LoRaWAN network operate in the unlicensed radio band known as the ISM band. While a LoRaWAN network can be deployed anywhere in the world, there are different regulatory requirements depending on the location of the deployment.

At the moment, there are a few different versions of the LoRaWAN® specification that are available to developers. Each supports slightly different functionality. So, which version should you use when developing LoRaWAN-based solutions?

The short answer is that the most current version of the specification for which there is a Certification program is LW 1.0.2. The Certification program for LW1.0 has been withdrawn and the Certification Program from LW1.0.1 will be withdrawn at the end of 2019.

While LW 1.0.2 is the most stable, you may want to consider using LW 1.0.3. This version of the specification adds support for Class B functionality; however, in the United States, there is a minor change that has delayed creation of a Certification test.
