Abstract: In a communication system for vehicle-to-environment communication, data to be transmitted is transmitted wirelessly as data packets. The system includes a communication unit and an application unit which are in contact with one another via an internal communication link, the communication unit having a high-frequency antenna and a transceiver for physical data transmission, in addition to a data processor for controlling the physical transmission. The application unit has at least one data processor configured to execute application programs, to control the access of the application programs to the vehicle-to-environment communication and to execute data communication security applications. The data processor of the application unit is configured to forward the data packets including the routing between communication users and to segment the data stream.

Abstract: A communication device for a motor vehicle has a plurality, but preferably two, communication modules that are configured in each case to communicate wirelessly with other motor vehicles and wirelessly with one another. A motor vehicle is equipped with a communication device of this type, and a method for communication between a plurality of motor vehicles is carried out.

Abstract: A method for determining a number of vehicle-to-X messages to be discarded, wherein a work cycle of a vehicle-to-X communication unit involves vehicle-to-X messages being received, wherein the work cycle involves a number of received vehicle-to-X messages being determined, wherein the work cycle involves an existent computation power being available and wherein the work cycle involves the number of vehicle-to-X messages to be discarded being determined on the basis of the number of received vehicle-to-X messages. The invention additionally relates to a corresponding system and to a use for the system.

Abstract: A multiband shark fin antenna for a vehicle may include at least one transmitting and one receiving antenna element from the group consisting of AM/FM antennas, telephone and RKE antennas, GPS antenna, SDARS antenna, stacked patch antenna, DAP antenna, WLAN antenna, WIMAX antenna or DRM antenna. The antenna elements are disposed beneath a joint shark fin-shaped outer cover on the exterior of the vehicle. On the inside, the shark fin-shaped outer cover includes an antenna circuit board having the antenna elements disposed thereon. Electronic adjustment or amplifier circuits including a transceiver, tuner or receiver are disposed on both the upper and lower faces of the antenna circuit board. Shielding plates, which shield the adjustment or amplifier circuits with respect to the antenna elements, are disposed on the upper side of the antenna circuit board.
