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) |
