The automotive industry has already begun incorporating a hands-free capability into the car and has done so quite quickly when the automotive design cycle is considered. A significant factor responsible for this adoption is the availability of Bluetooth-enabled phones. Bluetooth is a short-range wireless specification heavily promoted by cellular phone makers and offered on a wide variety of cellular phones. With this short-range radio hardware in place, any number of applications can be developed to take advantage of it. One such application is hands-free operation. In a hands-free system, the cell phone is the gateway that can transfer calls to an in-car audio system. Such a system consists of not only a Bluetooth radio, but also a computer capable of supporting all required communications protocol and audio processing.
