I would like to know too.  I have a similar problem.

I am a junior here and this year my project involves making a high speed
transmission link between two computers or a computer or a terminal.  I am
planning on using infra red LEDs or a semiconductor laser.  The goal is to
reach speeds in excess of 20000baud.  (I am not using fiber optics)

My problem right now is to figure out which is better, IR or Lasers.  Anybody
know?  I hear that IR has the drawback of being the same wavelength as the size
of fog droplets, therefore fog will block transmissions.  How about lasers?
What wavelengths can I use with lasers?

Thank you all.
