Well - Its not frequency - its modulation... Different types use AM (Amplitude Modulation) or FM (Frequency Modulation) to transmit sound... Not many use digital for infrared transmission because of the bandwidth requirements.. Infra red light is usually around the 900nm range..

Not a frequency, it's line-of-sight. That is why if you don't point the receivers at each other, it doesn't work. Frequency based items don't have to be in sight of each other, just within range. Infrared is an actual light, not visible to the naked eye.

Actually a question for Gravy Czar .. so you are saying light (infrared or else) does not have a frequency (and a wavelength)? If it does not, then you can try explaining to me how does light travel at all!

infra-red is a light beam.. not frequency.. you are thinking of radio waves etc....

oh they are around 950-970 nm. compatability is a question of whether they are analog or digital transmission.
