4.2	98
	99	Following is an example for how to join the [[TTN v3 LoRaWAN Network>>url:https://console.cloud.thethings.network/]]. Below is the network structure; we use the [[LG308>>url:http://www.dragino.com/products/lora/item/140-lg308.html]] as a LoRaWAN gateway in this example.

15.2	102	[[image:1654503992078-669.png]]
4.2	103
	104
	105	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.
	106
	107
	108	Step 1: Create a device in TTN with the OTAA keys from LSE01.
	109
	110	Each LSE01 is shipped with a sticker with the default device EUI as below:
	111
17.2	112	[[image:image-20220606163732-6.jpeg]]
