We bought a couple of "Fyre Fly" IR Transceivers (
http://www.rentron.com/Fyre-Fly.htm) and have been experimenting with them. Although operating at IRDA wavelengths, they have a different carrier frequency. The range is about 100 feet with both the narrow and wide LEDs running at 12VDC, line-of-sight, in a dark room. TV remotes don't seem to interfere with their IR. We are head-mounting one of them on our robotcoach, and are trying to figure out the best mounting configuration on the robot.
