LoRa, short for Long Range, is a wireless communication technology that enables low-power, long-range connectivity for IoT devices. It’s particularly suitable for remote sensors and devices that need to transmit small amounts of data over long distances. LoRaWAN is a protocol built on top of LoRa technology that defines the system architecture and communication between devices and gateways. This article introduces the key concepts and benefits of LoRa and LoRaWAN, and their role in enabling IoT applications.
