Bluetooth-based wireless connectivity in an automotive environment

In contrast to a home or office environment the automotive environment represents a relatively underdeveloped application field regarding the provision of new services (e.g. car-specific services) and/or access to existing services (e.g. Internet services). One of the key elements for accomplishing such a task is an appropriate, wireless delivery media. A combination of several dedicated access technologies (e.g. stationary/mobile operation) is not precluded. The integration of existing and new communication technologies requires an appropriate in-car infrastructure for the support of communication, information and entertainment services, which takes into account the specific characteristics and constraints of the considered automotive environment. It can be foreseen that Bluetooth, an emerging technology for short range wireless connectivity, will be an integral part of future car-based networks. The paper describes concepts for integration of the Bluetooth technology, the achievable transmission performance and a potential user application framework.
