110 +The LSE01 is configured as LoRaWAN OTAA Class A mode by default. It has OTAA keys to join LoRaWAN network. To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and power on the LSE0150. It will automatically join the network via OTAA and start to send the sensor value

127 +The LG308 is already set to connected to [[TTN network >>url:https://console.cloud.thethings.network/]], so what we need to now is configure the TTN server.
133 133  
134 -* Your local operator has already distributed a NB-IoT Network there.
135 -* The local NB-IoT network used the band that NSE01 supports.
136 -* Your operator is able to distribute the data received in their NB-IoT network to your IoT server.
