I wonder if it is worth bringing up this topic in the networking track
at Plumbers this year? It would be about the various limitation of
wireless-regdb today, such as:
- lack of PSD
- only one rule per band, preventing things such as
  - AP on 6 GHz in the US, as this thread mentions
  - very low power outdoor usage vs higher power but indoor-only usage

That said, I'm not in a position to implement anything to improve the
status quo.

I'm not sure who'd be there to discuss it with, I guess? I'm also not
sure who you'd even want to discuss it _with_, since it's mostly an
implementation detail and "just" needs to have something implemented, in
a creatively careful way not to break old stuff.

Subject: [PATCH] wireless-regdb: Permit lower 6 GHz band for Kazakhstan (KZ)
Message-ID: <20250930042948.427154-1-wens@kernel.org>

By Order of the Minister of Digital Development No. 564/NK dated
September 19, 2024 [1], an amendment was made to the assignment of
frequency bands, opening up the lower part of the 6 GHz band (5,945 MHz
to 6,425 MHz) was opened up to "SRD (wideband data transmission systems)
WAS/RLAN Data transmission systems/radio local area networks".

The power is limited to 200 mW e.i.r.p. with a spectral density of 10
mW/MHz. Only indoor use is permitted.

While at it, also change the power limits to use mW units to match the
official documents.

Initial information was provided by the Wi-Fi Alliance website, which
has a map [2] showing all countries that have enabled 6 GHz WiFi, and
links to official documents. This document was not sufficient as it did
not include power limits or other restrictions.

A subsequent search found a blog post [3] providing details and titles
of the official documents in English. An AI agent was used to search
for the original text of said order [1] after rummaging through
government websites in Russian and Kazakh failed to find anything.

The power limit of 5150-5350 MHz is 200 mW, maximum spectral density
e.i.r.p. 10 mW/MHz.

So, 5250 - 5350 should be 23 dBm or 200 mW.

I had this question as well. Looking at the original submission history,
it seems that the limit for 5250-5350 MHz was halved to cover TPC
requirements. See [1]. I'd like to follow the existing values unless
someone can point to documents stating otherwise.

Thanks
