[PATCH 2/3] wireless-regdb: update regulatory rules for India (IN) on 6 GHz for 2025

[Ping-Ke Shih]

From: Ping-Ke Shih <pkshih@realtek.com>

Ministry of communications, India released 6 GHz [1] on the 16th May 2025.
Technical parameters are listed on page 7:

 * Lower power indoor
   - Indoor
   - Max. PSD e.i.r.p: 5 dBm/MHz
     (Since minimum bandwidth is 20 MHz for WiFi, e.i.r.p limit is 18 dBm)
   - Max. e.i.r.p: 30 dBm
   - Max. Emission Bandwidth: 320 MHz
 * Very lower power outdoor
   - Outdoor
   - Max. PSD e.i.r.p: -5 dBm/MHz
   - Max. e.i.r.p: 14 dBm
   - Max. Emission Bandwidth: 320 MHz

I see.

I will drop this for now then, unless Ping-Ke has any more information
on this?


Thanks

What I can find is a consultation [1] on May this year. It needs some
time to have decision then.

Please drop this.

Hi All,

One query with respect to adding EIRP values (or max power) in the database.
As per draft regulations, max EIRP across different channel bandwidth will differ in 6 GHz band.

Like, in 20 MHz channel bandwidth, max allowed EIRP will be 18 dBm whereas for 320 MHz channel, the max allowed EIRP will be 30 dBm.

How we can add this info in the wireless regdb ? Apologies if i am missing something.

Regards,
Gaurav Kansal

That is basically spelling out the PSD restrictions that other regulations
describe in terms of dBm/MHz.

Unfortunately the database format does not support this, so we are limited
to only adding the lowest limit.

Last I asked, the kernel has a PSD field, but it doesn't really do anything
with it. And internally I asked folks working with WiFi to ask our partners,
and they seem to handle PSD restrictions within their firmware.
