184 184  By default, the LT-22222-L is configured to operate in LoRaWAN Class C mode. It supports OTAA (Over-the-Air Activation), the most secure method for activating a device with a LoRaWAN network server. The LT-22222-L comes with device registration information that allows you to register it with a LoRaWAN network, enabling the device to perform OTAA activation with the network server upon initial power-up and after any subsequent reboots.
