[Jiaxun Yang]

China had updated regulations on ISM frequencies by
"工信部无〔2021〕129号".

The new regulation effectives from Jan 1 2022.

Update regdb accroading to it's attachment "2400MHz、5100MHz
和 5800MHz 频段无线电发射设备射频技术要求".

Thanks for the patch. I'm looking at a machine translation of the
document, and based on that I think one change needs to be made, see
below. If something was mistranslated or if I misunderstood, please let
me know.

It looks like this range requires TPC, and if TPC is not supported the
max EIRP needs to be lowered by 3 dBm. Since Linux does not support TPC,
we need to reduce this power limit to 20 dBm.

Thanks,

Thanks for pointing.

I asked a RF expert and he adviced you're right :-)

v2 is on the way.

Hi Chen-Yu,

I didn't see this commit in[1], did you move upstream repo?
Better to update documents here[2] as well :-)

[PATCH] wireless-regdb: Update regulatory rules for China (CN)

[Jiaxun Yang]

China had updated regulations on 5150 MHz to 5350 MHz by
"中华人民共和国工业和信息化部令（第54号）", which released
an update to "中华人民共和国无线电频率划分规定".

The new regulation effectives from 1 July 2023.

In updated regulation, footnote "CHN44" had restricted 5150 MHz to
5350 MHz as in door only for Broadband Wireless Access systems.
