# LoRaWAN

LoRaWAN, which stands for Long Range Wide Area Network, is a wireless communication protocol designed for low-power IoT devices. It enables secure and scalable data transmission over long distances while consuming minimal power. This makes it well-suited for widespread use in smart cities, industrial IoT, and agricultural applications.

This document describes LoRaWAN protocol support and the data transmission payload structure.
