ABSTRACT:
A mobile radio system that permits broadband radio transmission in which a mobile station (MS) can be assigned a plurality of subscriber channels (TCH) of different widths. To accomplish this, concentrators (SMX) are connected to the base stations (BS, BS') of the mobile radio system and to the mobile station (MS). These concentrators (SMX) operate in an asynchronous transfer mode to combine a plurality of subscriber channels (TCH) into one transmit channel (DL) by statistical time-division multiplexing and to separate a receive channel (UL) into the plurality of subscriber channels (TCH) by statistical time-division demultiplexing. This provides a broadband wireless link between the mobile station and the base stations which is characterized by a flexible number of subscriber channels that can have different widths. In one embodiment of the mobile radio system according to the invention, the base stations (BS, BS') operate in a common-channel mode and are connectable with the mobile station (MS) via directional radio links (P, P'). Through this combination of common-frequency working, directional radio, and ATM, the invention can be used to advantage in the mobile radio field.
