Hello, We are trying to find out which regulatory domain HK falls under. >From db.txt country HK: (2402 - 2482 @ 40), (20) (5170 - 5250 @ 80), (17) (5250 - 5330 @ 80), (24), DFS (5490 - 5710 @ 80), (24), DFS (5735 - 5835 @ 80), (30) So the DFS regulatory domain is not specified hence We will not be able to start the AP on the DFS channel. Can somebody please clarify? In other cases e.g. GB country GB: DFS-ETSI (2402 - 2482 @ 40), (20) (5170 - 5250 @ 80), (20) (5250 - 5330 @ 80), (20), DFS, NO-OUTDOOR (5490 - 5710 @ 80), (27), DFS # 60 gHz band channels 1-4, ref: Etsi En 302 567 (57240 - 65880 @ 2160), (40), NO-OUTDOOR The regulatory domain is specified. So does HK fall under DFS-FCC or DFS-ETSI? Thanks atul
