Abstract:
1. A base station for communicating signals between an operator and one or more mobile units by means of an antenna system having a plurality of radiating elements, wherein: the system is arranged to process the signals as a plurality of component signals, each component signal being associated with one or more radiating elements within the antenna system, and modulating means are arranged to apply complex weights to the component signals such that summation of the component signals results in the production of an antenna beam direction dependent on the value of the complex weights, and wherein splitting, combining, and component signal amplifying means is provided between the application of the complex weight to the component signal and the component signal passing through its associated radiating element or elements, characterised in that: the splitting and combining means incorporates an interface allowing other operators to be connected simultaneously to the same antenna system, with each operator operating on a different frequency, and the system further includes a measurement receiver, and a data hub, wherein the measurement receiver is adapted to take a complex measurement from any component signals in the vicinity of the antenna system and generated by any base station connected to the antenna system, and to pass the measurement to the generating base station via the data hub, to enable phase component signal phase correction due to changes in feeder length between the base station and the antenna.
