Differences between LoRaWAN and DASH7.

What is in the Whitepaper?

Of all the unlicensed spectrum LPWAN technologies it would appear that the LoRaWAN standard seems to be gaining the most market traction. The most cited reasons for choosing LoRaWAN is the large communication range and the wide ecosystem of compatible sensors and gateway equipment. By standardizing on a LoRaWAN network deployment, industrial customers hope to cover a large number of use cases with only a limited investment in shared infrastructure.

However, as always, there is no silver bullet technology, and this is certainly true in industrial IoT. In this document we will look into different application trade-offs and the underlying aspects responsible for these limitations. For instance, for meter reading type of applications (a reading being taken every hour) it might be acceptable to miss some messages, but other industrial use cases require better reliability, especially for control systems or safety related use cases. In addition to reliability we will also explore aspects like latency, scalability, bidirectional communication, multi-cast communication and legislation. We will be comparing (private) LoRaWAN and the DASH7 Alliance Protocol mainly in industrial IoT use cases.
