Packet Forwarder

What is it?

A packet forwarder is a program that runs on a LoRa-based gateway (with or without GPS). It interacts with the LoRa chip to receive and transfer LoRa packets as well as with the network to transport them for applications.

How does it work?

First, a packet forwarder serves to forward radio frequency (RF) packets received by the concentrator (uplinks) to the LoRaWAN® Network Server (LNS) over a secured IP link.

It also transfers RF packets sent by the LNS (downlinks) over the same secured IP to one or many devices. Lastly, the packet forwarder is capable of transferring beacon signals, which are intended to coordinate the network’s devices. There is a possibility to transfer these beacons GPS-synchronously across the entire network.
