U
The following table shows the mapping relation between thEe regulation channel list and table index

or the regulation country codes, which are ISO 3166-1 alpha-2 codems. For example: US (0x55,
D
0x53), CN (0x43, 0x4E), JP (0x4A, 0x50), EU (0x45, 0x55).
I o
When the field “ucRegChannelListMap” is set to 0, tFhe specifiedc country code in field “aucCountryCode”
will be used to find corresponding channel list by this map.ping table. If the specified country code
N
e
is not found, the channel list in the “EU” (Europe union) country code will be adopted. In case the
l
supported channel list of the target countryO is changed or no adequate channel list is found, we can
i
set channel list specifically by utilizing “ucRegChannbelListIndex” or “aucRegSubbandInfo” field.

When the field “ucRegChannelListMap” is set to 1, “ucRiegChannelListIndex” field represents the value of
b
channel list index field in above mapping table of country channels and the listed 2.4/5GHz
C
channels in the same row will be used. o
For example: a country code is “X X” and its rmegulation channel list is the same with USA’s list. The
K
related fields should be set as {aucCountryCode= XX, ucRegChannelListMap=1, ucRegChannelListIndex=0}
o
E
When the field “ucRegChannelListMap” isn set to 2, “aucRegSubbandInfo” field represents the channel lists
of all 6 sub-bands. Each Tsub-band has 6 bytes structure, which is the format of tuple {Regulation
n
class, Band, Channel span, First channel number, Number of channel, Reserved}.
