Indoor (clause 2.나) PSD limits, including antenna absolute gain (EIRP-PSD): 5925-6425 MHz: 5 dBm/MHz, 320 MHz max occupied bandwidth 6425-7125 MHz: 2 dBm/MHz, 320 MHz max occupied bandwidth Both ranges are indoor only, restricted to equipment connected to building power, with mobile use prohibited. The previous combined entry from MSIT 2024-22 used a single 2 dBm/MHz PSD across the full 5925-7125 MHz range; 2026-10 split the bands and raised the lower band PSD from 2 to 5 dBm/MHz. The regdb has no PSD encoding, so the EIRP value is derived from the PSD limit at the smallest channel width permitted by the regulation (20 MHz), which is the most restrictive interpretation: 5925-6425: 5 dBm/MHz × 20 MHz = 18 dBm 6425-7125: 2 dBm/MHz × 20 MHz = 15 dBm Split the existing combined rule into two ranges to reflect the per-band PSD difference, and add AUTO-BW so adjacent ranges combine at the lower limit. Raise the maximum bandwidth from 160 to 320 MHz per the explicit "320 MHz 이하" in the regulation.

The v2 values were the PSD limit × 320 MHz, which would over- radiate narrow channels by up to 12 dB versus the regulation's PSD cap. Encoding at the narrowest channel ensures the regdb value is PSD-compliant at all permitted widths. - Acknowledge the 2024-22 → 2026-10 PSD change explicitly: lower band raised from 2 to 5 dBm/MHz, upper band unchanged at 2 dBm/MHz, indoor only. - Use the regulation's wording "PSD including antenna absolute gain" (effectively EIRP-PSD) rather than bare "EIRP". v1: https://lore.kernel.org/wireless-regdb/20260411222155.299441-3-loukot@gmail.com/ v2: https://lore.kernel.org/wireless-regdb/20260416120001.979135-1-loukot@gmail.com/ db.txt | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/db.txt b/db.txt index c310b7f..92cf9cc 100644 --- a/db.txt +++ b/db.txt @@ -1135,8 +1135,9 @@ country KR: DFS-JP (5250 - 5350 @ 80), (20), DFS, AUTO-BW (5470 - 5725 @ 160), (20), DFS (5725 - 5850 @ 80), (23) - # 6 GHz band - (5925 - 7125 @ 160), (15), NO-OUTDOOR + # 6 GHz band - per MSIT Notice 2026-10 + (5925 - 6425 @ 320), (18), NO-OUTDOOR, AUTO-BW + (6425 - 7125 @ 320), (15), NO-OUTDOOR, AUTO-BW # 60 GHz band channels 1-4 (57000 - 66000 @ 2160), (43) base-commit: 0bfb3d418a27cccf313ae64b0ed909f3ad95fea6 -- 2.54.0
