Abstract

A communication system (10) has a first plurality of wireless basestations (18) having adaptive antennas with a plurality of main array antenna elements (56) for generating a plurality of communication beams. The system (10) further includes a gateway station (20) coupled to the first plurality of wireless basestations. Tha gateway station (20) forms a plurality of beams commands by communicating plurality of a control signals to the first plurality of wireless base stations (18) having a second plurality of adaptive antennas with a second plurality of main array antenna elements for generating a plurality of communication beams to communicate with said mobile user. A
gateway station coupled to said first plurality of wireless base stations and said second plurality of wireless base stations through a plurality of multiple dynamic links, said gateway station forming a plurality of beams with a plurality of data packets by communicating plurality of a control signals to the base station to form the communication beams using at least one link from a first base station and a second link through a second of the base station.
