I suppose that's one purpose. Why it was off topic is that you didn't ask about 
how you might do this with the gnuradio platform, or in general how
it might be done with SDR, you simply asked a question about how 802.11
radios work, and that is better answered elsewhere (like wikipedia, or
the IEEE specs, or an O'Reilly publication).

Some progress has been made to this end. You'll find plenty of discussion
in the list archives about it. I'd suggest you start there:

Or, if you like big links:
