To allow the frequencies available for a radio network to be used more efficiently and consequently the cluster size of a radio network to be reduced, it is known to carry out frequency hopping for traffic channels. Such a process cannot be used, however, for signalling channels, in particular the BCCH channel. A further improvement in the frequency utilization in a radio network has been achieved by using a radio system with a plurality of base stations (10), which respectively have at least one transmitter (TX) and one receiver (RX1, RX2), each base station (10) being assigned at least one dual-polarized antenna (27). More efficient utilization of the available frequency band, and consequently a reduction in the cluster size, is made possible by the dual-polarized antenna being assigned a polarization modulator (24) for changing at predetermined points in time the polarization state of a transmit signal to be transmitted.
