[PATCH] wireless-regdb: TH gets 5 GHz enabled as of new regulatory rules

[Luis R. Rodriguez]

Phattanon Duangdara reported the National Telecommunication
Commisions of Thailand has announced new regulatory rules
about 5GHz for RLAN last year.

I have verified this matches our documentation internally
at Atheros.

Re: [PATCH] wireless-regdb: TH gets 5 GHz enabled as of new regulatory rules

[Phattanon Duangdara]

I corrected redgb from my knowledge.

For 5150-5350 is for Indoor Use Only.
Most of the regulartory refer _either_ FCC or ETSI/ITU standard, so I
guess that from the document 40MHz can also be used (same as US)
because TH regulatory mostly cover all bandwidth on 40MHz.
I corrected power but What a field before power is (that is now N/A below) ?

Note: this e-mail is in a public mailing list.

Adding Michael and David. Michael, I'd appreciate your review on this,
if possible.

Phattanon, thanks for your review of the TH document and sharing it
with us. Please see my reply inline below.

Did you see my patch? I corrected TH to be:

country TH:
        (2402 - 2482 @ 20), (N/A, 20)
        (5170 - 5250 @ 20), (3, 17)
        (5250 - 5330 @ 20), (3, 20), DFS

What do you mean by that? Do you mean that the document refers to FCC
and ETSI/ITU standard for regulatory purposes for some items?

Are you saying the Thailand document refers to FCC for max allowed
bandwidth spacing and therefore US max bandwidth spacing should be
used (ie allow 40 MHz width channels)?

> I corrected power but What a field before power is (that is now N/A below) ?

The rules can be read as follows:

(start - end @ max bandwidth spacing), (max antenna gain, max eirp)

Either, does that mean either FCC, or ETSI or ITU, you take a pick?
That would seem pretty vague for regulatory purposes.

This too?? I ask because I see FCC mentioned.

I am not sure about this. But if equipment that comply with FCC
standard allow to use 40MHz, I think we can because, for example
Translated rule for 2.4GHz says

===

Rules for communication equipment that use 2.400-2.500 GHz band:

Communication equipment that use 2.400-2.500 GHz band must stated and
comply with
one of following standards:

2.1.2.1  EN 300 328-2  :  Electromagnetic compatibility and Radio
spectrum Matters
(ERM); Wideband Transmission systems; Data transmission
equipment operating in the 2,4 GHz ISM band and using
spread spectrum modulation techniques; Part 2: Harmonized
EN covering essential requirements under article 3.2 of R&TTE
Directive
2.1.2.2  FCC Part 15.247 :  Code of Federal Regulations (USA); Title 47
Telecommunication; Chapter 1 Federal Communications

Yes. I managed to get translated documents, but for now I didn't get

So, is the patch from Luis wrong?  If so, what is the correct patch?

Although Phattanon didn't post a patch I interpreted it as he was
suggesting we can enable 40 MHz channels on Thailand as well since he
points out that Thailand regulatory rules refer to the FCC for
bandwidth compliance.

Michael does this interpretation match yours? Can we allow 40 MHz in TH?

Phattanon also specified some differences on max EIRP but I think that
should go as a separate patch and reviewed as such.
