With all the buzz around Wi-Fi, Bluetooth, and other wireless technologies, it's easy to overlook one of the simplest and most common forms of wireless communications out there: infrared. Anyone who's ever used a remote control has used it! Infrared makes use of the invisible spectrum of light just beyond red in the visible spectrum.
