So, which IEEE<->Frequency mappings should we be all using?

[Adrian Chadd]

Hi all,

I've been increasingly asked to bring up FreeBSD on "other" bands.

* 420MHz
* 700MHz
* 900MHz (which we already have, due to history);
* 3.6GHz
* 4.9GHz

I'd also like to support half and quarter width channels on these
frequencies. If I use the 2GHz channel mapping method, I end up with a
very restricted channel set and it definitely has no "gaps" for
5/10MHz increments.

Now, what I'd like to do is figure out some sane, shared method of
translating channel frequencies to IEEE numbers and back. That way the
BSDs and Linux (and maybe commercial stacks; I dunno what they do) can
have some sane chance of interoperating.

So: Is there some standardised or semi-standardised channel mapping
method? Or should we invent one?
