maybe i'm blind. but you reduced the channel width from 160 to 80 mhz. but i can't find any restriction in the document in a quick review Sebastian Am 18.02.2017 um 07:35 schrieb Ryan Mounce: > Sourced from the latest legislation at > https://www.legislation.gov.au/Details/F2016C0043 > > The current rules exceed legal limits between 5250-5330MHz, and permit > illegal operation in 5600-5650MHz (reserved for weather radar). > > Signed-off-by: Ryan Mounce <ryan@mounce.com.au> > --- > db.txt | 15 ++++++++++----- > 1 file changed, 10 insertions(+), 5 deletions(-) > > diff --git a/db.txt b/db.txt > index 05108e0..b951e0c 100644 > --- a/db.txt > +++ b/db.txt > @@ -85,12 +85,17 @@ country AT: DFS-ETSI > # 60 GHz band channels 1-4, ref: Etsi En 302 567 > (57000 - 66000 @ 2160), (40) > > +# Source: > +# https://www.legislation.gov.au/Details/F2016C00432 > +# Both DFS-ETSI and DFS-FCC are acceptable per AS/NZS 4268 Appendix B > country AU: DFS-ETSI > - (2402 - 2482 @ 40), (20) > - (5170 - 5250 @ 80), (17), AUTO-BW > - (5250 - 5330 @ 80), (24), DFS, AUTO-BW > - (5490 - 5710 @ 160), (24), DFS > - (5735 - 5835 @ 80), (30) > + (2402 - 2482 @ 40), (36) > + (5170 - 5250 @ 80), (23), NO-OUTDOOR, AUTO-BW > + (5250 - 5330 @ 80), (23), NO-OUTDOOR, AUTO-BW, DFS > + (5490 - 5590 @ 80), (30), DFS > + (5650 - 5730 @ 80), (30), DFS > + (5735 - 5835 @ 80), (36) > + (57000 - 66000 @ 2160), (43), NO-OUTDOOR > > country AW: DFS-ETSI > (2402 - 2482 @ 40), (20)
Hi Sebastian, There is no explicit channel width restriction in the document, however the only band in which the current regdb rules permit 160MHz operation (5490-5710MHz) would result in an overlap with the restricted weather radar band 5600-5650MHz. While remaining in compliance with both 802.11 and Australian law, contiguous 160MHz operation in 5GHz is only permitted between 5170-5330MHz which spans two bands with slightly different requirements, hence AUTO-BW.

Australian regulations differ from most of Europe, the USA and even New Zealand (which shares AS/NZS 4268) in that any unlicensed operation between 5600-5650MHz is prohibited outright, rather than being allowed after an extended DFS channel availability check. The situation appears to be similar in Canada, the regdb has previously been amended to reflect this. https://git.kernel.org/cgit/linux/kernel/git/sforshee/wireless-regdb.git/commit/db.txt?id=ce7697d3def48f87427b3a3c285b46241af3b79d On 19 February 2017 at 22:46, Sebastian Gottschall <s.gottschall@dd-wrt.com> wrote: > Am 19.02.2017 um 01:01 schrieb Ryan Mounce: >> >> Hi Sebastian, >> >> There is no explicit channel width restriction in the document, >> however the only band in which the current regdb rules permit 160MHz >> operation (5490-5710MHz) would result in an overlap with the >> restricted weather radar band 5600-5650MHz. > > thats the case for all countries, so this couldnt be a argument. dfs should > handle this > >> >> While remaining in compliance with both 802.11 and Australian law, >> contiguous 160MHz operation in 5GHz is only permitted between >> 5170-5330MHz which spans two bands with slightly different >> requirements, hence AUTO-BW. >> >> Regards, >> Ryan Mounce >> >> ryan@mounce.com.au >> >> On 19 February 2017 at 07:15, Sebastian Gottschall >> <s.gottschall@dd-wrt.com> wrote: >>> >>> maybe i'm blind. but you reduced the channel width from 160 to 80 mhz. >>> but i >>> can't find any restriction in the document in a quick review >>> >>> Sebastian >>> >>> >>> Am 18.02.2017 um 07:35 schrieb Ryan Mounce: >>>> >>>> Sourced from the latest legislation at >>>> https://www.legislation.gov.au/Details/F2016C0043 >>>> >>>> The current rules exceed legal limits between 5250-5330MHz, and permit >>>> illegal operation in 5600-5650MHz (reserved for weather radar). >>>> >>>> Signed-off-by: Ryan Mounce <ryan@mounce.com.au> >>>> --- >>>> db.txt | 15 ++++++++++----- >>>> 1 file changed, 10 insertions(+), 5 deletions(-) >>>> >>>> diff --git a/db.txt b/db.txt >>>> index 05108e0..b951e0c 100644 >>>> --- a/db.txt >>>> +++ b/db.txt >>>> @@ -85,12 +85,17 @@ country AT: DFS-ETSI >>>> # 60 GHz band channels 1-4, ref: Etsi En 302 567 >>>> (57000 - 66000 @ 2160), (40) >>>> +# Source: >>>> +# https://www.legislation.gov.au/Details/F2016C00432 >>>> +# Both DFS-ETSI and DFS-FCC are acceptable per AS/NZS 4268 Appendix B >>>> country AU: DFS-ETSI >>>> - (2402 - 2482 @ 40), (20) >>>> - (5170 - 5250 @ 80), (17), AUTO-BW >>>> - (5250 - 5330 @ 80), (24), DFS, AUTO-BW >>>> - (5490 - 5710 @ 160), (24), DFS >>>> - (5735 - 5835 @ 80), (30) >>>> + (2402 - 2482 @ 40), (36) >>>> + (5170 - 5250 @ 80), (23), NO-OUTDOOR, AUTO-BW >>>> + (5250 - 5330 @ 80), (23), NO-OUTDOOR, AUTO-BW, DFS >>>> + (5490 - 5590 @ 80), (30), DFS >>>> + (5650 - 5730 @ 80), (30), DFS >>>> + (5735 - 5835 @ 80), (36) >>>> + (57000 - 66000 @ 2160), (43), NO-OUTDOOR >>>> country AW: DFS-ETSI >>>> (2402 - 2482 @ 40), (20) >>> >>> >>> >>> -- >>> Mit freundlichen Grüssen / Regards >>> >>> Sebastian Gottschall / CTO >>> >>> NewMedia-NET GmbH - DD-WRT >>> Firmensitz: Berliner Ring 101, 64625 Bensheim >>> Registergericht: Amtsgericht Darmstadt, HRB 25473 >>> Geschäftsführer: Peter Steinhäuser, Christian Scheele >>> http://www.dd-wrt.com >>> email: s.gottschall@dd-wrt.com >>> Tel.: +496251-582650 / Fax: +496251-5826565 >>> > > > -- > Mit freundlichen Grüssen / Regards > > Sebastian Gottschall / CTO > > NewMedia-NET GmbH - DD-WRT > Firmensitz: Berliner Ring 101, 64625 Bensheim > Registergericht: Amtsgericht Darmstadt, HRB 25473 > Geschäftsführer: Peter Steinhäuser, Christian Scheele > http://www.dd-wrt.com > email: s.gottschall@dd-wrt.com > Tel.: +496251-582650 / Fax: +496251-5826565 >

The changes also increases the limits for most other ranges, by quite a bit in some cases. Seems that this should also be mentioned in the changelog, and I'd like to be able to check those changes against the documentation.

All of the updated power limits are converted to dBm but otherwise straight out of the document, so they shouldn't be a problem. I'll update the changelog to note this. The frequency ranges have been "rounded down" to conform with the apparent convention of only including ranges used by standard 802.11 channels, rather than using the actual frequency ranges as has been done for some countries (and most 60GHz rules). My preference is the latter so that there is a clear correlation between the regdb and relevant documentation, and so that the regdb may become useful beyond 802.11. With your blessing as maintainer I will also make this change to the patch.

Yes, I prefer the documented ranges as well. Thanks, Seth
