Abstract

Various antenna arrangements are provided with active transmit and receive antenna elements for transmitting and receiving signals within a cellular communication system. Also presented are specific base station antenna systems and methods, and portions thereof, which improve and control specific characteristics and features of antenna systems including antenna beam patterns. In addition, a method for the optimization of a cellular communications network is provided which exploits reverse-link, forward-link, and pilot signal information to optimize network operations.
