Abstract: A multi antenna system, comprising a plurality of transceivers for an antenna array operable for communication with wireless terminals, wherein the multi antenna system comprises a radio controller, adapted to operate a first transceiver for radio communication within a first bandwidth, wherein the first transceiver is limited by hardware to radio communication within the first bandwidth, a second transceiver adapted for radio communication within a second bandwidth selectable from a plurality of bandwidths, a radio controller adapted to operate, depending on a data rate demand, either the first transceiver or the second transceiver or both for radio communication.

Abstract: A multi antenna system (100), comprising a plurality of transceivers (1, . . . 64) for an antenna array (102) operable for communication with wireless terminals (301, . . . , 307), wherein the multi antenna system (100) comprises a radio controller (104), adapted to operate a first transceiver for radio communication within a first bandwidth, wherein the first transceiver is limited by hardware to radio communication within the first bandwidth, a second transceiver adapted for radio communication within a second bandwidth selectable from a plurality of bandwidths, a radio controller (104) adapted to operate, depending on a data rate demand, either the first transceiver or the second transceiver or both for radio communication.
