Question about 5.8 GHz in E.U.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello

Sorry, I'm kind of discovering all those wifi stuff and I'm not sure to 
follow your argument.

What I can see in current DB version is that some E.U. countries have it 
enabled :

e.g. Germany :

|country DE: DFS-ETSI (2400 - 2483.5 @ 40), (100 mW) (5150 - 5250 @ 80), 
(100 mW), NO-OUTDOOR, AUTO-BW (5250 - 5350 @ 80), (100 mW), NO-OUTDOOR, 
DFS, AUTO-BW (5470 - 5725 @ 160), (500 mW), DFS # short range devices 
(ETSI EN 300 440-1) (5725 - 5875 @ 80), (25 mW) # 60 GHz band channels 
1-4 (ETSI EN 302 567) (57000 - 66000 @ 2160), (40) |

Mathieu Peyrega
