Systems, methods, and computer-readable media herein dynamically modify the beam patterns used by an antenna array to communicate with user devices in a sector. A set of metrics are monitored and used to generate time-averaged beam quality values for a default beam pattern and then compared to a time-averaged beam quality of a subset of beams within the default beam pattern. If the time-averaged beam quality for the subset of beams exceeds a percentage of the time-averaged beam quality of the default beam pattern, the antenna array is re-assigned to communicate via a second beam pattern.
