Abstract

A communication system (10) has a high altitude device (19) having an adaptive antenna (31) with a plurality of main array antenna elements for generating a plurality of communication beams. The system (10) further includes a gateway station (20) coupled to the high altitute device. The gateway station (20) forms a plurality of beams commands by communicating plurality of a control signals to the high altitude device station to form the communication beams.
