All,
I have used the CRDA capability using the "iw" tool to set the country code.
When I use the 'iw reg get' command, the return below is diplayed.
country JP:
(2402 - 2472 @ 40), (N/A, 20)
(2457 - 2482 @ 20), (N/A, 20)
(2474 - 2494 @ 20), (N/A, 20), NO-OFDM
(4910 - 4930 @ 10), (N/A, 23)
(4910 - 4990 @ 40), (N/A, 23)
(4930 - 4950 @ 10), (N/A, 23)
(5030 - 5045 @ 10), (N/A, 23)
(5030 - 5090 @ 40), (N/A, 23)
(5050 - 5060 @ 10), (N/A, 23)
(5170 - 5250 @ 40), (N/A, 20)
(5250 - 5330 @ 40), (N/A, 20), DFS
(5490 - 5710 @ 40), (N/A, 23), DFS
I would like to understand exactly what is displayed.
- the number of line (xxx-xxx @ xx), (xx,xx) is equal to the number of
channel which can be accessed
- What is the meaning of each line and details on each parameter.
Thx and regards

(aaaa-bbbb @ c),(n/a, 23), XXX
each line is a range in frequencies (channels that fall between aaaa
and bbbb. c is the channel width (10 Mhz for Japan's narrow channels,
20 Mhz for regular channels and 40 Mhz for wide channels). 23 is the
maximum Tx power e.i.r.p. in db.

Many thanks for your support and the link. One additional parameter
'N/A' is my example are sometimes fills w/ a number depending on the
country I set.
What is the meaning of this parameter, I didn't catch it on the
Regulatory page.
Thx
Sebastien

It is the maximum antenna gain: look at
http://wireless.kernel.org/en/developers/Regulatory/Database and click
on one of the countries there.
