Wireless- infrared connectivity
Infrared systems use very high frequencies, just below visible
light in the electromagnetic spectrum, to carry data. Because infrared
technology is fairly limited in respect to the distance that two communicating
devices can be apart, it is primarily used as a way for a laptop user to connect
to a printer.
