A system for transmitting and receiving radio signals is disclosed. The system includes a controller having a modem and a transmission amplifier module connected to the modem, an antenna unit arranged at a distance from the controller and having an antenna and a reception amplifier module connected to the antenna, and a high-frequency cable connecting the controller and the antenna unit.

Transmitting/receiving system for radio signals having an integrated transmission amplifier protection function

The present disclosure relates to a method for transmitting at least one data packet between a first communication subscriber of a communication arrangement and at least one second communication subscriber of the communication arrangement, wherein the at least one data packet is transmitted from the first communication subscriber to the second communication subscriber at least partially via a bidirectional direct connection set up between a communication module of the first communication subscriber and a communication module of the at least one second communication subscriber, wherein the first communication subscriber and/or the at least one second communication subscriber is a vehicle, and wherein the at least one second communication subscriber feeds back a receipt for respective data of the at least one data packet to the first communication subscriber.

Feedback channel for secure data transmission

The present disclosure relates to a system for exchanging signals between a device of a vehicle and an external apparatus outside the vehicle via at least one antenna of the vehicle, wherein high-frequency signals are exchanged between the at least one external apparatus and the at least one antenna of the vehicle via electromagnetic waves, wherein the at least one antenna is connected via at least one first path to a first end of a line of the vehicle, and the device is connected via at least one second path to a second end of the line of the vehicle, wherein the system has at least one frequency reduction module which is arranged along at least one of the paths, and wherein the at least one frequency reduction module is designed to adjust a value of a frequency of the high-frequency signals to a low value prior to transport along the line.

Systems for transporting externally received signals within a motor vehicle

The present disclosure relates to a system for a motor vehicle for exchanging information with at least one further motor vehicle, wherein the system has a central processing unit with a processing core, which is connected to at least one antenna module, wherein the at least one antenna module is designed to exchange signals containing information with the at least one further motor vehicle, wherein an application for carrying out a motor vehicle to motor vehicle communication is installed in the processing core, wherein the processing core is designed to control the at least one antenna module by carrying out a signal processing.

System and method for exchanging information

The disclosure relates to a radio modem for a motor vehicle, having an antenna arrangement, an AD-DA converter and a processor for exchanging communications data between the motor vehicle and at least one object in the vicinity of the motor vehicle. The processor is configured to provide at least one communications standard, which in each case specifies a digital protocol stack for controlling the exchange of communications data and a radio frequency ffor a radio signal, and implementing every provided communications standard by operating the associated protocol stack and by providing a digital mixer, which is coupled on a baseband side to the protocol stack and on an HF side to the AD-DA converter and which provides for the radio frequency fon the HF side, wherein the AD-DA converter is connected directly between the processor and the antenna arrangement.

Motor vehicle with radio modem, radio modem, and method for exchanging communication data

This disclosure relates to a control device for coupling an antenna assembly of a motor vehicle to at least one vehicle component of the motor vehicle for an exchange of messages with vehicle-external objects. The control device comprises a first radio module for providing a first radio link to at least one of the objects on the basis of a first radio standard, a second radio module for providing a second radio link to at least one other of the objects on the basis of a second radio standard, and a processor device for receiving some of the messages via the first radio link and some other of the messages via the second radio link. The processor device includes a synchronization unit configured to forward the received messages in a sequence determined by the time data to the at least one vehicle component.

Control device and method for coupling a multi-standard antenna assembly of a motor vehicle to at least one vehicle component

At least one communication service for transmitting and/or receiving information associated with the communication service utilizes at least one of several antennas in a motor vehicle. An antenna circuit, associated with each of the antennas, converts an analog signal received by the antenna into digital received data associated with that antenna circuit and/or converts digital transmission data associated with that antenna circuit into an analog transmission signal which is supplied to the associated antenna. A communication device in the motor vehicle generates transmission data associated with the antenna circuits in accordance with transmission information and transfers the transmission data to the associated antenna circuit and receives the digital received data from at least one of the antenna circuits to provide reception information based on the digital received data.

Motor vehicle having a plurality of antennas and at least one communication device

The disclosure refers to a roof antenna module and to a method for operating the roof antenna module, wherein a communication control unit couples at least one transceiver with at least one bus connection and communication messages are transmitted between the at least one transceiver and the at least one bus connection. This approach prevents undesired manipulation of the motor vehicle from the outside. This approach uses a filter device of the communication control unit, that forwards a control instruction to the at least one bus connection only if the control instruction fulfills a predetermined safety criterion.

Motor vehicle roof antenna module, motor vehicle and method for operating the roof antenna module

A switching apparatus alternately connects a mobile radio module and an E-Call controller to an antenna/ The switching apparatus includes a first signal input, a second signal input, an antenna connection and a changeover device that changes between a first switching state and a second switching state, based on at least one switching signal. In the first switching state, only the first signal input is electrically connected to the antenna connection, and in the second switching state, only the second signal input is electrically connected to the antenna connection. To prevent a connected transmission devices from diagnosing decoupling from the antenna connection as a fault, in at least the second switching state the changeover device electrically connects the signal input that is decoupled from the antenna connection to a terminating device which emulates an antenna at the signal input that is connected to the terminating device.
