Hands-free telephony for cars

The Car Working Group of the Bluetooth Special Interest Group has shown how Bluetooth wireless technology will enable hands-free use of mobile phones in cars.

The Car Working Group of the Bluetooth Special Interest Group (SIG) has released a definition showing how Bluetooth wireless technology will enable hands-free use of mobile phones in automobiles.

These enhancements are part of the new ‘Hands Free Profile’ and are expected to be adopted by the Bluetooth SIG membership. Prototype products using this specification are expected by the end of this year.

The Bluetooth SIG provides a forum for companies to work together using short-range wireless technologies to solve customer problems. In response to interest by the automotive industry, the Bluetooth SIG formed the Car Working Group in December of 1999. The ‘Hands-Free profile’ is the first of several application level specifications expected from the working group.

Using the new Hands-Free profile, products that implement the Bluetooth specification can facilitate automatic establishment of a connection between a car’s hands free system (typically part of its audio system) and a mobile phone. Bluetooth wireless products that incorporate these enhancements will enable a virtually automatic interface between the car and wireless products.

Work continues among the Bluetooth Promoter and Associate member companies to add additional capabilities to the Bluetooth wireless specification.
