I was thinking that if you actually separated the routes of
transmission from reception (use LEDs for reception, and standard RF
for transmission), there could be some security gains from the fact
that a cracker would have access to both (most conversations are
fairly unintelligible if you don't hear the both sides).
Additionally, it seems in theory that the bandwidth can be doubled as
you're no longer requiring any channel to do double-duty or
full-duplex.
It's done for satellite internet. Seems to be especially popular in
Europe and the middle east.

Sounds like the next generation of mobile devices will use this approach too
