1. A method for optimizing an antenna of a source cell in a wireless communications network, the method comprising:
- evaluating relationships between a source cell and a plurality of target cells by;
projecting a beamwidth geometry for the source cell;
projecting a beamwidth geometry for each target cell of the plurality of target cells;
determining whether the projected beamwidth geometry of each target cell envelops the source cell; and
determining whether the beamwidth geometry of the source cell envelops respective target cells,determining an optimization value based on the evaluated relationships; and
adjusting an antenna parameter of the source cell based on the optimization value, the antenna parameter being selected from a tilt angle and a transmit power; and
when the projected beamwidth geometry of the source cell envelops the target cell and the projected beamwidth geometry of the target cell does not envelop the source cell, calculating a first value corresponding to an overshooting condition of the antenna,wherein the first value is used in determining the optimization value.

9. A wireless communications system comprising:
-
a source cell including a source antenna; a plurality of target cells each including target antennas; a processor; a memory; and a non-transitory computer readable medium with computer executable instructions stored thereon which, when executed by the processor, perform the following steps; evaluating relationships between a source cell and a plurality of target cells by; projecting a beamwidth geometry for the source cell; and determining whether the beamwidth geometry of the source cell envelops respective target cells; projecting a beamwidth geometry for each target cell of the plurality of target cells, and determining whether the projected beamwidth geometry of each target cell envelops the source cell, determining an optimization value based on the evaluated relationships; and adjusting an antenna parameter of the source antenna based on the optimization value, the antenna parameter being selected from a tilt angle and a transmit power, wherein projecting the beamwidth geometry for the source cell includes projecting an area defined by the beamwidth of the source cell from a geographic location of a base station associated with the source cell, and projecting the beamwidth geometry for each target cell includes projecting an area defined by the beamwidth of a given target cell from a geographic location of the given target cell, wherein, when the projected beamwidth geometry of the target cell envelops the source cell and the projected beamwidth geometry of the source cell does not envelop the target cell, calculating a second value corresponding to an undershooting condition of the antenna, and wherein the second value is used in determining the optimization value. - View Dependent Claims (10, 11, 12, 13, 14, 15)
