Wider channel widths have a higher noise floor, therefore specifying a fixed PSD allows wider channels to operate at a higher EIRP to maintain the same S/N ratio as smaller channel widths. Clause 4.6.2 requires non-client (AP devices to have a maximum PSD of 5 dBm/MHz and a maximum EIRP of 30 dBm. Clause 4.6.3 requires client (STA) devices to have a maximum PSD of -1 dBm/MHz. Clause 4.4 specifies a maximum channel width of 320 MHz. Clause 4.9 specifies indoor use only. Operation on oil platforms, vehicles, boats, trains, and drones is prohibited except on commercial aircraft above 10,000 feet altitude. There is no IR (Initiate Radiation) restriction mentioned in the 6 GHz specification. The following equation is used to calculate the EIRP from the PSD and channel width: EIRP = PSD + 10*log(channel width in MHz) Using the maximum PSD values of 5 and -1 for APs and STAs respectively, the EIRP in dBm for a given channel width can be calculated: Channel Width (MHz) AP STA ------------------------------------------------ 20 18 12 40 21 15 80 24 18 160 27 21 320 31 (max 30) 25 (max 24) For channel widths up to 160 MHz, the maximum PSD is the limiting factor. For the 320 MHz channel width, the maximum EIRP is the limiting factor. Unfortunately, because there is currently no mechanism to specify different power levels for AP and STA modes, and for different channel widths, the smallest value has to be selected, which is 12 dBm. This will likely cause connectivity problems with larger channel widths until these additional parameters can be added. signed-off-by: Dennis Bland <dennis@dbperformance.com> --- diff -up a/db.txt b/db.txt --- a/db.txt 2022-04-08 09:54:37.000000000 -0600 +++ b/db.txt 2022-04-20 18:55:30.000000000 -0600 @@ -298,8 +298,9 @@ country BZ: DFS-JP (2402 - 2482 @ 40), (30) (5735 - 5835 @ 80), (30) -# Source: +# Sources: # https://www.ic.gc.ca/eic/site/smt-gst.nsf/vwapj/rss-247-i2-e.pdf/$file/rss-247-i2-e.pdf +# https://www.ic.gc.ca/eic/site/smt-gst.nsf/eng/sf11750.html (6 GHz operation) country CA: DFS-FCC (2402 - 2472 @ 40), (30) (5150 - 5250 @ 80), (23), NO-OUTDOOR, AUTO-BW @@ -307,6 +308,7 @@ country CA: DFS-FCC (5470 - 5600 @ 80), (24), DFS (5650 - 5730 @ 80), (24), DFS (5735 - 5835 @ 80), (30) + (5925 - 7125 @ 320), (12), NO-OUTDOOR # Source: # http://www.art-rca.org On Tue, Apr 19, 2022 at 1:53 PM Seth Forshee <sforshee@kernel.org> wrote: > > On Sun, Apr 17, 2022 at 07:41:03PM -0600, Dennis Bland wrote: > > The technical/operational requirements have been available since November 2021: > > > > https://www.ic.gc.ca/eic/site/smt-gst.nsf/eng/sf11750.html > > > > If this request is not already in the submission queue, I can look at > > submitting a patch. > > We don't have any patches pending for this, so feel free to send one! > > Thanks, > Seth > On Tue, Apr 19, 2022 at 1:53 PM Seth Forshee <sforshee@kernel.org> wrote: > > On Sun, Apr 17, 2022 at 07:41:03PM -0600, Dennis Bland wrote: > > The technical/operational requirements have been available since November 2021: > > > > https://www.ic.gc.ca/eic/site/smt-gst.nsf/eng/sf11750.html > > > > If this request is not already in the submission queue, I can look at > > submitting a patch. > > We don't have any patches pending for this, so feel free to send one! > > Thanks, > Seth _______________________________________________ wireless-regdb mailing list wireless-regdb@lists.infradead.org http://lists.infradead.org/mailman/listinfo/wireless-regdb ^ permalink raw reply [flat|nested] 4+ messages in thread

Thanks for the patch and the detailed explanation. Everything here looks good to me. The patch itself was corrupted. I fixed it up by hand, but for future patches you might try 'git send-email', or if that won't work with your email provider you can use 'git format-patch' and attach the patch file. Also note that Signed-off-by should be capitalized. I fixed that when applying. Applied, thanks! _______________________________________________ wireless-regdb mailing list wireless-regdb@lists.infradead.org http://lists.infradead.org/mailman/listinfo/wireless-regdb ^ permalink raw reply [flat|nested] 4+ messages in thread
