Concentrator Modules for LoRaWAN®
Add LoRaWAN Connectivity to IoT Gateways
With their small form factor, RAK concentrators are suitable for both new product development and integration into existing products.


RAK concentrator modules are powered by Semtech and build the core functionality of every LoRaWAN network. They are the hardware heart of gateways, connecting IoT end-user devices to the network backbone.
How Concentrators Work
The concentrator is an essential part of any gateway for LoRaWAN and enables the reception and transmission of data packets from and to the end devices. It can receive multiple signals to serve a large number of end devices.
