Abstract:
The object of the present invention is to provide an active antenna system which is flexibly configurable and efficient in operation. According to a first aspect of the present invention an active antenna system comprises a radio equipment having a plurality of transceiver modules, each transceiver module being connected to at least one antenna, and a radio equipment control unit having a hub being connected to the transceiver modules via an antenna interconnect. The hub is embodied for receiving base band signals via the antenna interconnect from the transceiver modules and to extract channel signals from the received base band signals. As the hub is arranged in the radio equipment control unit which is part of a base station the base band signals are transmitted to the radio equipment control unit without extracting the channel signals. This allows easily to distribute the base band signals on several data connections, particularly several antenna cables, of one antenna interconnect. This results in a reduced information loss and minimizes the requirements for the transmission capacity of a single data connection of the antenna interconnect between the radio equipment control unit and the radio equipment. The radio equipment control unit does receive all the information which is originally received by the transceiver modules.
