Extend the last 5 GHz frequency range to 5850 MHz. WiFi 6E is now allowed with the following restrictions: * Indoor: the full 1.2 GHz range, up to 160 MHz bandwidth and 250mW EIRP * Outdoor: the lower 500 MHz range, up to 160 MHz bandwidth and 25mW EIRP Here only the former entry is added. And also update the regulatory source links. Signed-off-by: Sungbo Eo --- I have two questions. The regulation has one more restriction: The TX power should not exceed 2.5 mW/MHz when the frequency range includes the whole or a part of 5230-5250 MHz and the bandwidth is equal to or less than 40 MHz. That leads to the followings: 5230-5250 @ 20 -> 17 dBm 5210-5250 @ 40 -> 20 dBm 5170-5250 @ 80 -> 23 dBm Is it possible to add this rule without lowering the TX power for 80 MHz bandwidth? And do we need AUTO-BW for 6E channels? I thought it is for merging adjacent frequency ranges. --- db.txt | 11 ++++++++--- 1 file changed, 8 insertions(+), 3 deletions(-) diff --git a/db.txt b/db.txt index 6e8dbef..31052cf 100644 --- a/db.txt +++ b/db.txt @@ -862,15 +862,20 @@ country KP: DFS-JP (5490 - 5630 @ 20), (30), DFS (5735 - 5815 @ 20), (30) +# Source: +# https://www.law.go.kr/LSW//admRulLsInfoP.do?chrClsCd=&admRulSeq=2100000196972 +# https://www.law.go.kr/LSW//admRulLsInfoP.do?chrClsCd=&admRulSeq=2100000196973 +# https://www.law.go.kr/LSW//admRulLsInfoP.do?chrClsCd=&admRulSeq=2100000196974 country KR: DFS-JP # ref: https://www.rra.go.kr (2400 - 2483.5 @ 40), (23) (5150 - 5250 @ 80), (23), AUTO-BW (5250 - 5350 @ 80), (20), DFS, AUTO-BW (5470 - 5725 @ 160), (20), DFS - (5725 - 5835 @ 80), (23) - # 60 GHz band channels 1-4, - # ref: http://www.law.go.kr/%ED%96%89%EC%A0%95%EA%B7%9C%EC%B9%99/%EB%AC%B4%EC%84%A0%EC%84%A4%EB%B9%84%EA%B7%9C%EC%B9%99 + (5725 - 5850 @ 80), (23) + # 6 GHz band + (5925 - 7125 @ 160), (24), NO-OUTDOOR, AUTO-BW + # 60 GHz band channels 1-4 (57000 - 66000 @ 2160), (43) country KW: DFS-ETSI
