In v1/v2 it was 24 dBm, then in v3 you lowered it for indoor/outdoor. Now you've chaned it back to indoor only, but the limit is 15 dBm rather than the 24 you had in v1/v2. Why the change?

Why > the change? 24 dBm in v1/v2 was from max EIRP for 160 MHz, but I realized I should use PSD instead of EIRP, and I got 2 dBm/MHz * 20 MHz = 15 dBm (to fit the smallest bandwidth).

This patch is based on MSIT Public Notification 2021-86 ("Unlicensed Radio Equipment Established Without Notice"), officially announced on 2021-11-29. The PSD must not exceed 2.5 mW/MHz if the frequency range includes all or part of 5230-5250 MHz and the bandwidth is equal to or less than 40 MHz. This leads to the following: * 5230-5250 @ 20 -> 17 dBm * 5210-5250 @ 40 -> 20 dBm Here the power limit for >20 MHz bandwidth is also lowered to 17 dBm, as it's not possible to set different power limits for different bandwidths at the moment. Extend the last 5 GHz frequency range to 5850 MHz. Wi-Fi 6E is now allowed with the following restrictions: * Indoor: the full 1.2 GHz range, up to 160 MHz bandwidth and 2 dBm/MHz PSD * Outdoor: the lower 500 MHz range, up to 160 MHz bandwidth and 25 mW EIRP Here only the former entry is added. And also update the regulatory source links. Signed-off-by: Sungbo Eo <mans0n@gorani.run> --- v4: * merge 5210-5230 MHz band rule * revert back to "indoor only" 6E rule as its power limit is higher v3: * update regulatory source to newer revision * replace "indoor only" 6E rule with "both indoor and outdoor" rule as "indoor only" rule limits PSD instead of EIRP v2: * split 5150-5250 MHz band rule to accommodate the PSD limit * remove AUTO-BW flag from 6 GHz band rule --- db.txt | 16 +++++++++++----- 1 file changed, 11 insertions(+), 5 deletions(-)
