A wireless communication network which includes an antenna array (26) for receiving and transmitting signals to and from remote users which is capable of adapting to widely varying traffic levels. Different antenna elements (24) can be turned on during high user periods and off when there are fewer users. Also, beam width can be varied, with fewer antennas having wide beams in use when traffic levels are low and more antennas with narrow beams when traffic is high. Generally, the maximum capibility uses 180 antenna elements with beam widths of about 2 DEG to cover a full 360 DEG . This network can act as either a circuit switched network or a packet switched network, as desired.
