Subject: wireless-regdb: Why crda db.txt disallows 40Mhz BW on Channel 12-13 for JP?
Date: Mon, 02 Aug 2010 17:25:32 +0530 [thread overview]
Message-ID: <4C56B234.3040209@marvell.com> (raw)
Hello All,
Crda db.txt has following entries for JP:
(2402 - 2472 @ 40), (N/A, 20)
(2457 - 2482 @ 20), (N/A, 20)
Why are channel 12 and 13 for JP disallowed to operate in 40Mhz by this file?
As per Annex 11J of latest 802.11n spec, for Japan, channel 1-7 are allowed in HT40+ and channel 5-13 are allowed in HT40- mode.
Thanks,
Yogesh
