<mask>: The frequency mask that the network may work with, 16
bit corresponds to 16 frequency groups, see LoRaWAN access spe
cification for details.
For example: 0-7 channel, the corresponding mask is 0001, 8-15 c
hannel corresponding mask is 0002, 1 6-23 channel corresponding
mask is 0 004 and so on.
The frequency corresponding to the specific channel needs to chec
k the region protocol. For example, the channel 0-7 in CN470 cor
responds to: 470.3MHz, 470.5MHz, 470.7MHz, 470.9MHz, 471.1M
Hz, 471.3MHz, 471.5MHz, 471.7MHz .
