Use of back lobe antenna gain to determine antenna elements in MIMO sectors
Systems, methods, and computer-readable media herein dynamically adjust the number of elements active within a neighboring base station in order to reduce the back lobe overlap and thus reduce the interference caused by such an overlap. User devices assigned to communicate with an antenna array are monitored to determine if they are experiencing a decreased level of performance which may be caused by an overlapping back lobe from a neighboring cell site. If the user device's performance falls below a threshold value, the gain associated with the neighboring cell site is dynamically reduced in order to reduce the back lobe overlap.
