The FCC is trying to assist airports that use Terminal Doppler Weather Radar (TDWR) systems in avoiding interference with some outdoor wireless systems operating in the 5.4 GHz (5470 MHz - 5725 MHz) band. One of the things they have decided on is to disallow operation on the 5600 MHz - 5650 MHz frequency range inclusive. What this means in practice is 5 GHz 802.11 devices programmed to operate in the US will have these channels now disabled: * 5600 MHz [120] (disabled) * 5620 MHz [124] (disabled) * 5640 MHz [128] (disabled) This is documented on the FCC Knowledge based Publication Number: 443999 [1] [1] https://fjallfoss.fcc.gov/oetcf/kdb/forms/FTSSearchResultPage.cfm?switch=P&id=41732 Cc: Michael Green <Michael.Green@xxxxxxxxxxx> Cc: Senthil Balasubramanian <senthilkumar@xxxxxxxxxxx> Cc: David Quan <David.Quan@xxxxxxxxxxx> Signed-off-by: Luis R. Rodriguez <lrodriguez@xxxxxxxxxxx> --- I'm on 2 hours of sleep due to jet lag so I had chopped out channel 132 (5660 MHz) but this is not required obviously. This v2 fixes that. db.txt | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) diff --git a/db.txt b/db.txt index 84be443..c8b1ef0 100644 --- a/db.txt +++ b/db.txt @@ -562,7 +562,8 @@ country US: (2402 - 2472 @ 40), (3, 27) (5170 - 5250 @ 40), (3, 17) (5250 - 5330 @ 40), (3, 20), DFS - (5490 - 5710 @ 40), (3, 20), DFS + (5490 - 5600 @ 40), (3, 20), DFS + (5650 - 5710 @ 40), (3, 20), DFS (5735 - 5835 @ 40), (3, 30) country UY: -- 1.6.0.4 -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
