Dear all,
in the file RegionAS923.h there is a channel plan for Japan CHANNEL_PLAN_GROUP_AS923_1_JP_CH37_CH61_LBT_DC.
When selected, it configures the frequency range from 922.4MHz to 928.0MHz which corresponds to CH37 to CH61, respectively.
On the other hand, latest ARIB-T108 v1.5 specifies (in page 76 Table 3-33) that the channel range where both LBT and DC rules need to be followed is from CH33 to CH61, for 20mW or less antenna power.
Is there any reason why the implementation consider the starting channel as CH37 and not CH33?
BR,
Antonio
