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
(5490 - 5710 @ 20), (3, 20), DFS
(5735 - 5835 @ 20), (3, 30)

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)?

The rules can be read as follows:
(start - end @ max bandwidth spacing), (max antenna gain, max eirp)

Michael, does your concur with this?

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.

Thanks, did this came from the TH document?
