129		-=== 2.2.1 Test Requirement ===
	129	+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.

	132	+[[image:1654503992078-669.png]]
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.
137	137
	135	+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.

139		-Below figure shows our testing structure. Here we have NB-IoT network coverage by China Mobile, the band they use is B8.  The NSE01 will use CoAP((% style="color:red" %)120.24.4.116:5683)(%%) or raw UDP((% style="color:red" %)120.24.4.116:5601)(%%) or MQTT((% style="color:red" %)120.24.4.116:1883)(%%)or TCP((% style="color:red" %)120.24.4.116:5600)(%%)protocol to send data to the test server
