[PATCH 0/5] wireless-regdb: Fix incorrect entries found during comprehensive audit

[Louis Kotze]

Following the South Africa (ZA) 6 GHz LPI fix submitted earlier, I
audited all 182 countries in wireless-regdb across all WiFi bands
(2.4 GHz, 5 GHz, 6 GHz, and 60 GHz), cross-referencing against
official regulatory documents.

This series fixes six incorrect entries found during the audit:

Patches 1-3: 6 GHz power/bandwidth corrections
  - HK: VLP (14 dBm) → LPI (24 dBm), freq 5925→5945, add NO-OUTDOOR
  - KR: 15 dBm/160 MHz → 27 dBm/320 MHz per MSIT 2026-9
  - RU: 100 mW → 200 mW per GKRCH Decision 22-65

Patch 4: DFS flag cleanup
  - TG: Remove DFS from 2.4 GHz, 6 GHz, and 60 GHz (only valid on 5 GHz)

Patch 5: Unit typo fix
  - UA: 60 GHz changed from (40 mW) back to (40) dBm — accidental
    mW suffix added in commit 90e83fc

Each patch includes the specific regulatory citation used for
verification.

[PATCH 1/5] wireless-regdb: Update 6 GHz rules for Hong Kong (HK)

[Louis Kotze]

OFCA published HKCA 1081 Issue 2 (August 29, 2025), updating the
6 GHz WLAN specification for Hong Kong:

  - LPI (indoor): 24 dBm EIRP
  - VLP (outdoor): 14 dBm EIRP
  - Frequency: 5945-6425 MHz (5925-5945 reserved as guard band)

The previous entry had VLP power only (14 dBm), no indoor flag, and
used the wrong frequency start (5925 instead of 5945).

Update to LPI with correct frequency range and NO-OUTDOOR flag.

As you mentioned, 5926-5945 is reserved as a guard band, i.e. the
device cannot use it. So the rule is correct to start at 5945 MHz.

> Update to LPI with correct frequency range and NO-OUTDOOR flag.

There should be justification for picking LPI over VLP, since this
is a choice made on the submitter's end. Same applies to the other
patches.

There was one submission that picked VLP over LPI in favor of outdoor
usage.

[PATCH 2/5] wireless-regdb: Update 6 GHz rules for South Korea (KR)

[Louis Kotze]

MSIT issued Announcement No. 2026-9 (February 10, 2026, effective
April 1, 2026), revising 6 GHz power limits and bandwidth:

  Lower band (5925-6425 MHz): 1 W (30 dBm) EIRP indoor
  Upper band (6425-7125 MHz): 0.5 W (27 dBm) EIRP indoor

MSIT Announcement No. 2024-22 (May 30, 2024) previously updated the
maximum bandwidth from 160 MHz to 320 MHz.

Since the database supports only one rule per band, use 27 dBm
(the upper band limit) to ensure compliance across the full
5925-7125 MHz range. Update bandwidth from 160 to 320 MHz.

The database supports one rule per frequency range.

You can write it as two ranges, and add AUTO-BW to both. The kernel
will see this and know that the two bands can be combined. That way
if someone is using a smaller channel width that fits into the lower
band, they can use a higher power limit. This is what we do for the
5 GHz bands that have varying requirements.

[PATCH 3/5] wireless-regdb: Fix 6 GHz LPI power for Russia (RU)

[Louis Kotze]

The State Commission for Radio Frequencies (GKRCH) Decision No. 22-65
(December 23, 2022) authorized 6 GHz LPI at 200 mW (23 dBm) EIRP
with 10 mW/MHz PSD. The current entry incorrectly uses 100 mW.

This page doesn't actually contain any useful information.

I can't seem to access the reference from the original submission.
I'll try again later.

I did find https://www.gccorp.com.tw/en/?p=2173 using the document name
you gave, but that also mentions that "automatic power control system"
is required. I assume that is TPC, which Linux basically doesn't have.
So we still have a problem here. If the rules were based on FCC or EU
regulations, then we sort of adopt a 3 dBm reduction in the limit.

[PATCH 4/5] wireless-regdb: Remove incorrect DFS flags for Togo (TG)

[Louis Kotze]

Commit aad0c26 (2024-07-19) added DFS flags to all bands for Togo,
including 2.4 GHz, 6 GHz, and 60 GHz. DFS is only applicable to
5 GHz bands where radar avoidance is required.

The source regulation (ARCEP Decision N 226/ARCEP/DG/22) does not
require DFS on 2.4 GHz, 6 GHz, or 60 GHz. Remove the incorrect
DFS flags from these bands while keeping DFS on the 5 GHz entries
where it is correct.

I don't read French, but my translation app says that DFS is required
for all bands except the 60 GHz band. I am looking at table 9 -
broadband data transmission devices (pages 20-21).

If you're looking at table 3 - non-specific SRDs, then you get a much
lower power limit.

[PATCH 5/5] wireless-regdb: Fix 60 GHz power unit for Ukraine (UA)

[Louis Kotze]

Commit 90e83fc (December 2020) changed Ukraine's 60 GHz entry from
(40) to (40 mW), likely an accidental addition of the mW suffix
when converting other bands to mW notation. This reduces the power
limit from 40 dBm (10 W) to 40 mW (16 dBm) — a 1000x reduction.

ETSI EN 302 567, referenced in the entry's comment, specifies
40 dBm EIRP for 60 GHz. All other ETSI-based countries in the
database use 40 dBm for this band.

Restore the correct power of 40 dBm.
