Q:  What is Infrared?

Infrared is an invisible band of radiation at the lower end of the electromagnetic spectrum. It starts at the middle of the microwave spectrum and goes up to the beginning of visible light. Infrared transmission requires an unobstructed line of sight between transmitter and receiver. It is used for wireless transmission between computer devices as well as most all hand-held remote controller units for TVs, video and stereo equipment.
