I use one of these as an AP:


It comes with openWRT, which worked well enough, although I have flash upgraded 
to ROOter - the locally maintained derivative.

Also available as a bare board from the same vendor, which might save a little 
bit of space.  Worth checking out to ascertain the orientation of the internal 
antenna.  Either do require 5V power via microUSB socket.

Might not quite fit your space requrement, but I mount mine higher than other 
kit, using self-adhesive hook & loop tape, and connect to a switch via cat 5 

I use mine only at short range.  In my (limited) experience low powered AP 
don't penetrate walls etc very well.
