2 ways that have worked for me, both using the long range IR mode:
1) Point the RCX's IR Port at the ceiling and your IR Transmitter/
reciever unit at the ceiling and bounce the signals off your ceiling.
I have vaulted ceilings painted white and get over 20 feet x 20 feet
coverage across a whole room, though your mileage may vary. I guess
you could also mount your transmitter on your ceiling too...
2) Mount the RCX's IR Port again pointing at the ceiling and place
a white paper cone or Aluminium foil cone pointed tip down (lame
ascii graphics follow):

And have your IR Transmitter/Reciever at roughly the same height
as the Cone pointing horizontally/parallel to the ground. A corner
of a room isn't a bad spot and you'll get some pretty decent
coverage (over 30 feet in my room, also bouncing off a completely
mirrored wall at the far end of the room. More prone to be blocked
by obstacles than method 1 above.
Low tech, but works. Once again, your mileage may vary.
