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.

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.
