Unfortunately this does not work. However, with AUTO_BW I believe that the kernel does allow a larger bandwidth when it spans adjacent channels, so it probably isn't necessary. Otherwise this mostly looks good, but a few changes are needed.

Either way, we can't have ranges overlapping like this. > + > + # Item 59 > + (2400 - 2483.5 @ 40), (4000 mW) > + > + # Item 61 > + (5150 - 5250 @ 80), (200 mW), NO-OUTDOOR, AUTO-BW > + > + # Item 62 (200 mW allowed if TPC is used) > + (5250 - 5350 @ 80), (100 mW), NO-OUTDOOR, AUTO-BW, DFS > + > + # Combine the above two bands to get a 160 MHz channel. > + (5150 - 5350 @ 160), (100 mW), NO-OUTDOOR, AUTO-BW, DFS As stated above, this rule needs to be removed. > + > + # Item 63(a) (1000 mW with TPC) > + (5470 - 5600 @ 80), (500 mW), DFS > + > + # Item 63(b) (1000 mW with TPC) > + # The end is 5725 but we borrow 5 MHz from the following less restrictive band > + # so we can get an 80 MHz channel. > + (5650 - 5730 @ 80), (500 mW), DFS > + > + # Item 60 > + (5725 - 5850 @ 80), (4000 mW) Please adjust this up to 5730 MHz to not overlap with the rule above it. > + > + # Item 22 > + (5850 - 5875 @ 40), (25 mW) You can't have a rule whose bandwith is greater than the range. And I'd think you'd want to add AUTO_BW to this and the previous range to allow use of channel 169, etc. > + > + # Item 63AA (25 mW if outdoors) > + (5925 - 6425 @ 160), (250 mW), NO-OUTDOOR > + > + # Item 65 > + (57000 - 71000 @ 2160), (20000 mW), NO-OUTDOOR I'm surprised at 20W since it also specifies compliance with FCC rules which as a max EIRP of 10W (though it does give a peak power emission of 20W). But I guess that's what it says. Thanks, Seth > > country AW: DFS-ETSI > (2402 - 2482 @ 40), (20) > -- > 2.40.0

But I guess that's what it says. I never received a response, so I went ahead and applied a version of this patch with the adjustments I noted above. Seth

- Update legislation link from March 2022 version to June 2023. - Add comments for each frequency range referring back to legislation. - Switch units from dBm to mW to match values listed in legislation. - Allow 5850-5875 at low power, as this has always been permitted. - Combine 5150-5350 bands to permit a 160 MHz channel. Signed-off-by: Adam Nielsen <a.nielsen@shikadi.net> --- Hi all, Just a few minor changes for AU. I have included (5150 - 5350 @ 160) which overlaps two existing bands, however I am not sure if this is the correct way to do it. From what I gather, having the two bands listed separately (items 61 and 62 in the patch below) would prevent a single 160 MHz channel from being spread across both bands. I figure adding another entry that covers both frequency ranges (with the most restrictive limitations) would permit the 160 MHz channel to be used, however please correct me if this is wrong. I added a bunch of comments pointing back to the relevant section of the legislation document as I found it a bit of a challenge to work out where each entry mapped back to. So hopefully this will make it easier for the next person to work out where the rules are coming from. If there are any other issues with the patch let me know.
