802.11a is another matter. This uses a different frequency altogether, in the 5GHz band, and as such utilizes a completely separate radio.

So, it's even more inconsistent than I feared!  How
often will I be likely to run into each of these
standards?  If 802.11a is quite rare I may ignore it.

These days, 802.11a is surely not very popular.

WiSP backhauls utilize 5 gHz unlicensed. There are a bunch of vendors that make a 2.4/5ghz radio card. I have a D-link for one and there are others as well as an FYI.

I don't think you'll see much end-user 5 gHz stuff, that's my personal opinion.
