    Re: 802.11a channels

    All channels should be available as they are non overlapping.

    Mainly because you can't get a decent signal once you are more than a gnat's pube away from the AP (ok ... exaggeration, but that is how it feels sometimes when you are used to b/g)

    Re: 802.11a channels

    Maybe I should have made myself more clear. There is a lot of information about the number of channels but not the channel numbers which I require so that I can configure Kismet.

    @plexer: Aren't those the channels for the US? I believe that Europe has a couple more.

    Re: 802.11a channels

    No, that is for 802.11b/g. In the US only channels 1 to 11 are usable, where as here in Europe we can use 1 - 13

    802.11a uses the same channels everywhere. Plexer is correct.

    Re: 802.11a channels

    I've looked it up in my access controller and (as I had previously read) Europe has 19 channels:
    36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136 and 140

    It seems that the US has 12.
