## LoRa WAN
[[File:LoRaWANSystemDiagram.JPG|750px]]
LoRa WAN is the internet-based version of LoRa. While LoRa communication only works between generally two devices, LoRa WAN can communicate between hundreds of devices by the means of a gateway. LoRa WAN consists of end-nodes and at least one gateway. Communication between the gateway and the nodes is bidirectional and based on LoRa radio communication.

## Gateway
A gateway can be a [LG01-N Single Channel Gateway](https://www.seeedstudio.com/LG01-N-Single-Channel-LoRa-IoT-Gateway-p-2935.html). It works in a LoRaWAN setup and communicates with the nodes. In a LoRaWAN setup, the nodes don't communicate with each other. A gateway creates a connection with the internet and uploads the data to a platform such as TheThingsNetwork (TTN). This is a potential great opportunity for improving the current system at the farm.</br>
