A radio device for the transmission of information has a radio-device control unit, at least one antenna, an antenna switchover unit and at least one radio unit. The radio device provides a static radio unit and at least one dynamic radio unit, wherein at least two radio units are radio-ready, so that, by means of a switchover signal of the radio-device control unit, a switchover between the radio-ready radio units can be implemented in a real-time manner.

Radio device and a method for the transmission of information

A radio-device system with a monitoring unit is provided, wherein the monitoring unit is connected to a main-radio device and to an emergency-radio device. By means of a control signal of the monitoring unit, an antenna is connected either with the main-radio device or with the emergency-radio device. The monitoring unit is fitted with a time-evaluation unit, which evaluates the processing of the command with regard to a time parameter. Furthermore, a method is also provided for monitoring the implementation of a command of the main-radio device within the radio-device system.

Radio-device system and a method with time-parameter evaluation

A radio device is provided with a first radio unit and a second radio unit, wherein the first radio unit provides a certified functionality which is certified by an authorized certification authority. The second radio unit provides a certified functionality, wherein the functionality of the second radio unit is different from the functionality of the first radio unit, and the functionality of the second radio unit is similarly certified by an authorized certification authority. Furthermore, a method is provided for the transmission of information via the radio device.

Radio device with two radio units and a method for the transmission of information

A communications system provides a first communications device, which is connected via a bidirectional transmission channel to a second communications device, wherein the communications devices each comprise a data reconstruction unit. Each communications device comprises a control unit, which is provided for a configuration of various transmission parameters such as modulation type and/or code rate and/or transmitter power and/or size of data packets dependent upon a reliability value evaluated within the control unit. The reliability value indicates a probability for a reliability or a quality of a data reconstruction, which reconstructs transmitted data from received signals within the data reconstruction unit.

Communications system and method for the adaptation of transmission parameters on the basis of reliability information of reconstructed data

A method for multi-hop data transmission in an ad-hoc network comprising concealed nodes. A source node determines the probability of a collision-free transmission of data to the following nodes and if a high probability of collision-free transmission is present, transmits a data packet to a following node without coordinating transmission-channel allocation with concealed nodes disposed in the vicinity of the next node.

Method for multi-hop data transmission in an ad-hoc network comprising concealed nodes

The invention relates to a method and system for addressing and routing in coded communications relationships in at least two different network levels of a network with different routing levels, which are separated from one another. A first network level with the associated first routing level is demarcated from a second network level with a second routing level via at least one coding device. A network topology of both network levels is determined independently of one another in the at least two routing levels and stored respectively in routing tables. An interface in the at least one coding device is provided with an unambiguous allocation of addresses of the second routing level to addresses of the first routing level, in order to derive the topology of the second network level efficiently from the first network level.
