A company called Unwired Technology LLC has developed wireless technology that enables passengers to simultaneously receive up to four stereo or eight monaural channels connected to a vehicle's entertainment systems. It's called 'WhiteFire' and the company claims it is a major breakthrough, enabling passengers to select audio from various inputs such as DVD movies, CD players, video games, Internet devices, radios, or other devices installed in their vehicles. We questioned the company's president, Lawrence Richenstein, about WhiteFire's prospects.
