Abstract

Abstract Translated from German Bei einem Mobilfunksystem mit einer Zentrale und mit Feststationen, bei dem die Feststationen (FS₁ bis FS n ) Funksignale mobiler Teilnehmer (MS) senden und von diesen empfangen, werden erfindungsgemäß die Funksignale nicht wie üblich in den Feststationen erzeugt bzw. verarbeitet, sondern in der Zentrale (1). Die Zentrale (1) enthält also für jede Feststation (FS₁ bis FS n ) einen Mikrowellensender/-empfänger (SE₁ bis SE n ) , der die zu den Feststationen zu sendenden Signale in Funksignale umsetzt und die von den Feststationen empfangenen Funksignale in die Basisbandlage umsetzt. Dies hat den Vorteil, daß Trägerfrequenzeinrichtungen für eine Vielzahl von Feststationen gemeinsam verwendbar sind, so daß die Kosten des Systems verringert sind. In a mobile radio system with a central and with fixed stations, in which the fixed stations (FS 1 to FS n ) send and receive radio signals from mobile subscribers (MS), the radio signals are not generated or processed as usual in the fixed stations, but in the Head office (1). The center (1) thus contains for each base station (FS₁ to FS n ) a microwave transmitter / receiver (SE₁ to SE n ), which converts the signals to be sent to the base stations into radio signals and converts the radio signals received from the base stations into the baseband position . This has the advantage that carrier frequency devices can be used in common for a large number of base stations, so that the cost of the system is reduced.
