Abstract: 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.

Abstract: 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.

Abstract: 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.
