ABSTRACT:
It is proposed to create a new radio communication system (SYS) which is based primarily on existing technologies, by using a stationary and a mobile radio device (DBS; MMS) with standard technology. The radio devices are modified in such a way that for setting up the radio link between the radio devices, at least one of the radio devices (MMS) transmits in the opposite direction of the radio protocol (PGSM) one of the radio signals (FB) which is actually intended to be transmitted by the other radio device (DBS). For example, the radio signal (FB, frequency correction burst) which is intended only for the downward direction (DL, downlink) is here transmitted in the upward direction (UL, uplink). This modification requires only changes in the control software for the transmitter in the mobile radio device and for the receiver in the stationary radio device.
