376 +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?

392 +
393 +* 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.
