Unwired technology has introduced a new digital wireless format that it says enables reception of up to four stereo or eight mono audio channels simultaneously via wireless headset. According to the company, that gives vehicle passengers the ability to select audio from various inputs such as DVD movies, CD players, video games, internet devices and radios. The first product to employ the WhiteFire technology will be an Unwired-brand wireless headphone system for the automotive aftermarket, planned for release near the end of the year. Some of Umwired's OEM customers are expected to introduce similar systems under their own brands in early 2003.
