349 +
350 +Frequency band US915, AU915 and CN470 supports totally 72 frequency in 8 sub-bands, Normally Gateway only support 8 channels ( one subband). So how does the gateway and end nodes work in such frequency?

356 +* If Gateway choose (% style="color:blue" %)**Semtech UDP packet**(%%) forwarder to Connect to LoRaWAN server. User need to manually set the match Subband in the gateway web UI.
357 +
358 +* If Gateway choose (% style="color:blue" %)**Basic Station Mode**(%%) to connect to the LoRaWAN server. User can set the subband in the Server side and gateway will the correct subband from server. no need to set this in gateway. AWS-IoT, TTN, ChirpStack all supports Basic Station Connection.
359 +
360 +== 5.2 Set Subband in End Node ==
361 +
362 +
363 +* In early End Node firmware, it is pre-set to subband 2 , user need to manually set to proper subband if they don;t use subband 2.
364 +
365 +* In new end node firmware , it supports all sub-bands, and will swtich to the proper subband after OTAA join. So user can use the end node with all sub-band.
