A communication device for wireless communication in a mobile radio network is included in a controller installed in a motor vehicle. The controller also includes a connection device which connects to at least one bus system of the motor vehicle and a computer device for controlling the exchange of data between the at least one bus system and the mobile radio network and/or an external network. The communication device has, in addition to a connection to a controller-external mobile radio antenna, an additional mobile radio antenna which is integrated into the controller and is to be used in the event of failure of the controller-external mobile radio antenna. The communication device outputs an emergency call signal to the mobile radio network when an emergency trigger signal is received via the bus system and/or some other communication connection. |
