Hi,
The rules for Brazil were based on this normative
https://informacoes.anatel.gov.br/legislacao/resolucoes/2017/936-resolucao-680,
as mentioned in the comments of the entry.
This January came out a newer normative
https://informacoes.anatel.gov.br/legislacao/resolucoes/2025/2001-resolucao-772,
It allows 6GHz frequencies, so the line:
(5925 - 7125 @ 320), (12), NO-OUTDOOR, NO-IR
Should change for, at least:
(5925 - 7125 @ 320), (12), NO-OUTDOOR
The removal of NO-IR is important, since routers Wi-Fi 6E and 7 don't
work because of this outdated rule based on an outdated normative.
I'm no lawyer, so please if you see something different, like more
granular control in the allowed frequencies, please let us know.
Thanks,

Hi, I created a patch to solve that.

Subject: [PATCH] wireless-regdb: Update regulatory rules for Brazil (BR) on
6GHz
Change rules for 6GHz in Brazil, removing `NO-IR` and adding
`AUTO-BW` so the 6GHz band can be used.
Add the relevant normative in comments.

Those are very large documents. Could you help point out which sections
or comments apply to your argument?

https://informacoes.anatel.gov.br/legislacao/atos-de-requisitos-tecnicos-de-gestao-do-espectro/2024/1920-ato-915:
in the items IX.4 and IX.5 mentions the 6GHz frequency.
https://informacoes.anatel.gov.br/legislacao/resolucoes/2025/2001-resolucao-772:
You can search for "5925-6700" to check how the allocation is done.
It mentions satellites, so that's why I set indoors, but maybe you
understand that is not necessary.

This only covers point-to-point usage. You would need to modify the rules
and add the PTP flag. Likely not what you actually want.

This only gives the band allocation, not the requirements for each use.
Also, satellite communication is a different use category. We should look
for WiFi or RLAN, or perhaps "comunicação multimídia".
The requirements I were able to find are:

I understand. The problem is: with NO-IR set, we can't configure an AP,
since the AP is the initial radiator.
So we just could remove NO-IR so we can create and use APs in this range?
In this case, I will create a v3 of the patch that just removes NO-IR
and keeps the documentation links as is.
Please let me know what you think.

Based on that, what should be the maximum dBm? I saw it mentions 30dBm
but also 24dBm.

I created a v3 patch that updates the comments with the new normative
you found, removes the NO-IR so a AP can work correctly, and changed the
maximum power from 12 to 27, since for APs it seems to mention 30dBm,
but I considered TPC like the other frequencies.

You failed to consider the power spectral density requirement. As I
mentioned in a previous reply, the requirement for clients is -1 dBm/MHz,
which at the smallest channel width, translates to a power limit of around
12 dBm. The original value is correct.
The database in its current form simply does not have the capability to
model things like PSD or AP vs client device specificity.
If the regulations require NO-IR for clients, then we cannot remove it
just so that APs can work. See [1] for the same discussion for US 6 GHz.
Sorry.

Where can I check if the regulation requires NO-IR? I couldn't find any
mention to this.
