Hey Adrian, I looked it up and I was totally off on that greenfield thing
but it is the same as 802.11a.  Sorry I don't work on this stuff often
enough to be authoritative, didn't mean to confuse the matter.

If it help this paper has a really good write-up on it
www.arubanetworks.com/pdf/technology/whitepapers/wp_Designed_Speed_802.11n.pdf

Thanks. From doing some reading, looks like n really complicates some
things. I'm still not sure why the channel numbers are separated by 2 or 4
instead of 1 like the 2.4 band. For example, why channels 34, 36, 38 instead
of just an increment by one?

I could find the frequencies for the 2.4 variants of 802.11 every place,
but 802.11n when it's using 5 Ghz has been harder. I found this doc on
802.11a:

http://www.air-stream.org.au/channel_802_11a

does 802.11n have the same channels when it is using the 5 Ghz band? I'm
trying to prep up a bunch of info for a free wireless class I'm co teaching
here in the Louisville area.

Thanks much guys,

Adrian
