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.
L'invention est un nouveau système de radiocommunication (SYS) basé principalement sur les technologies actuelles qui utilise des dispositifs radio stationnaire et mobile (DBS; MMS) construits en technologies standard. Ces dispositifs radio sont modifiés de telle façon que, pour établir la liaison radio entre eux, l'un d'eux au moins (MMS) transmet en sens opposé à celui spécifié par le protocole radio (PGSM) l'un des signaux radio (FB) qui est sensé être transmis par l'autre (DBS). Par exemple, le signal radio (FB, salve de correction de fréquence) qui n'est sensé être transmis que dans la direction descendante (DL, liaison descendante) est ici transmis dans la direction ascendante (UL, liaison ascendante). Ce changement ne nécessite qu'une modification des logiciels de commande de l'émetteur du dispositif radio mobile et du récepteur du dispositif radio stationnaire.
