Vehicle communication systems allow passengers of the moving vehicle to contact the rest of the world using a cellular telephone network. These systems allow the transfer of speech and data for personal and business purposes, as well as a connection for traffic monitoring, navigation, diagnosis, entertainment and security applications. Many new vehicles on the market today come with systems that are connected to the services provided by the car manufacturer. With the help of these systems, drivers can come into contact with the service provider 24/7, or by one click of a button or automatically in case of an accident.
