351 +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?

362 +
363 +
364 +* 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.
365 +
366 +* 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.
