  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
