The radio system comprises a network part, subscriber terminals and a bidirectional transmission path between the network part and the subscriber terminal. The bidirectional transmission path consists of frames to be transmitted at a carrier wave frequency. A frame comprises time slots. To a time ...

In addition, the frequency of the main carrier wave may be periodically varied in an erratic manner. More than one supersonic frequency may be combined with the same carrier wave for multiplex working, and the system is also applicable to radio-dynamic control. The valve 20, Fig. 1, ...
