I am unable to submit a patch and I lack time to read through it all. Please correct the file according to the information I provided.
Otherwise you break regulatory in 5GHz for Austria.
Please report yourself after checking - you can simply check with the link from regulatory provided.

Resolution too_vague is inappropriate - if you want a proof, see the reference I provided - graphics for analphabets included.

It is still unclear what this ticket is about. Do you say 60GHz is not allowed in austria? I don't see any mention of that in the page you linked. It does not mention 2.4GHz either - so this is illegal too in austria?

No, Jow: try to do "sinnerfassend lesen" before stating "too_vague" ;-)

The values in 5 GHz are wrong. They differ.
Btw: the maximum transmit power was too low. Someone mixed up subclass 54 of the european guideline with other services mentioned somewhere else national law.

Well, if you insist on reopening this without providing a proper patch then so be it, I'll just ignore it from now on.

comment:7 Changed 3 years ago by anonymous

Well, if you insist on demonstration powers, you are free to do so. Your refusal won't improve OpenWRT's quality.

BTW, you could as Felix or Adrian, whether the regdb.txt is intended to indicate center frequencies or cf + bandwidth margins. If the regulatory states, that operation is intended from x to y, frequency margins depending on bandwidths are probably not wisely used.

E.g. - without 10MHz margins intended for 20MHz channels (what about offchannel usage and half-channels/half-bandwidth @10MHz with 5MHz margins?), it would read:

country AT: DFS-ETSI

(2412 - 2472 @ 40), (20)
(5150 - 5250 @ 80), (23)
(5250 - 5350 @ 80), (23)
(5470 - 5725 @ 80), (30), DFS
# 60 gHz band channels 1-4, ref: Etsi En 302 567
(57240 - 65880 @ 2160), (40), NO-OUTDOOR

Currently we'd be far beyond the allowed values in 2.4GHz with this method, while we could not fully use the allowed spectrum in 5GHz.
If the method using margins is the correct one, then it should be used consequently.

country AT: DFS-ETSI

(2402 - 2482 @ 40), (20)

#10 MHz below and 10 MHz above allowed center frequencies, while the band used may be up to 2483.5.

(5170 - 5250 @ 80), (20)

#starting 20 MHz above allowed minimum, ending strictly at 5250 w/o margin.

(5250 - 5330 @ 80), (20), DFS

#starting at 5250 exactly, but not including a 20MHz margin at the end - contradiction to previous rules.

(5490 - 5710 @ 80), (27), DFS

#starting 20 Mhz above allowed, ending 15Mhz below.

# 60 gHz band channels 1-4, ref: Etsi En 302 567
(57240 - 65880 @ 2160), (40), NO-OUTDOOR

Correct: see ticket's first post.

OpenWrt just copies the regdb.txt from the wireless-regbd project at [0].

I would suggest you send a patch with your improvements to wireless-regdb [at] lists.infradead.org and OpenWrt will just take the new regdb.txt then.

The rules include margins, but as far as I can tell, you did not check the channels available and some info might actually be wrong.
According to http://en.wikipedia.org/wiki/List_of_WLAN_channels (yes, might be too general, but I believe EU mostly has common rules), channel 34 (5170 cf, which would go to 5160) is not allowed and is not shown on phy info. So a 5170 starting frequency would be correct (ch. 36 5180-10Mhz). Also there is no channel 65 or 66 to use above 5330, so 64 (5320+10Mhz) is the correct limit with included end frequency. In the upper range, the first channel is 100 (5500), so again a 5490 start would seem to include the needed margin.

Just my 2 cents...
