	364	+= 5. Subband Related questiones in US915, AU915, CN470 bands. =
	365	+
	366	+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?
	367	+
	368	+== 5.1 Set Subband in Gateway. ==
	369	+
	370	+* If Gateway choose **Semtech UDP packet** forwarder to Connect to LoRaWAN server. User need to manually set the match Subband in the gateway web UI.
	371	+* If Gateway choose **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.
	372	+
	373	+== 5.2 Set Subband in End Node ==
	374	+
	375	+* 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.
	376	+* 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.
