Abstract
A system and method have been developed wherein a cylindrical antenna array is configured and reconfigured in a wireless communication network. Position and signal information are continuously received from wireless mobile units and are used to determine reconfigurations of antenna components of the cylindrical antenna array to enhance performance of the system. As such, base station antennas are dynamically configured to minimize such things as interference and dropped calls, and to maximize their voice quality both within a cell, and among neighboring cells.
