  * If there is public LoRaWAN network coverage in the area where you plan to install the device (e.g., The Things Stack Community Network), you can select a network and register the LT-22222-L I/O controller with it.
  * If there is no public LoRaWAN coverage in your area, you can set up a LoRaWAN gateway, or multiple gateways, and connect them to a LoRaWAN network server to create adequate coverage. Then, register the LT-22222-L I/O controller with this network.
