ABSTRACT:
The arrangement synchronizes the radio transmission in a radiotelephone subscriber connection network. The connection network for the subscriber connection to the telecommunication exchange (LE) is divided into a central control unit (RDU), at least one concentrating, decentralized unit (RBC), as well as a plurality of base stations (RBS) between which and subscriber stations the radio transmission to be synchronized occurs. The decentralized units contain receivers (GPS-E) for reference signals of a radio-locating system, for example GPS, beamed out by satellites and derive time signals therefrom for the time-division multiplex radio frame of the base stations that they transmit thereto via a U-interface (U).
