Product / service details

The LoRaWAN® Certification Program provides assurance to end customers that their application-specific end devices will operate on any LoRaWAN® network. The scope of the Certification Program confirms that the end device meets the functional requirements of the LoRaWAN® protocol specification. The program includes a suite of tests that are specified in the LoRa Alliance® End Device Certification Requirements document.
