1. A multi-carrier antenna system for cellular communication and broadcasting in a plurality of transmission modes within a geographic area divided into a plurality of cells, the multi-carrier antenna system comprising:

  • a plurality of antennas, wherein each of the antennas is capable of generating a beam pattern that may be adjusted in azimuth and elevation for purposes of transmitting signals to mobile devices;

    a signal distribution network coupled to the plurality of antennas, the signal distribution network enabling a plurality of input signals to be routed to one or more of the plurality of antennas; and

    a controller coupled to the signal distribution network and the plurality of antennas, the controller enabling the multi-carrier antenna system to be switched between a first mode of operation wherein at least one of the plurality of antennas has a beam pattern with a first azimuth pattern and a first elevation pattern, and a second mode of operation wherein the at least one of the plurality of antennas has a beam pattern with a second azimuth pattern and a second elevation pattern.
