Abstract

A communication system (10) has a base station having an adaptive antenna with a plurality of main array antenna elements for generating a plurality of communication beams. The system further includes a gateway station coupled to the base station. The gateway station forms a plurality of beams commands by communicating plurality of a control signals to the base station to form the communication beams.
