An example method is performed by a computing device for determining one or more tilt adjustments for cells included in a wireless communication network. The method includes receiving geo-located traffic data that includes a signal strength of a serving cell and a signal strength of a neighbor cell. The computing device then determines a number of occurrences that the neighbor cell has a signal strength greater than the serving cell based on the geo-located traffic data, and if the number of occurrences is greater than a dominance threshold, compares the signal strength of the serving cell with a signal strength threshold. A coverage adjustment is then generated that includes instructions to adjust a tilt angle of an antenna included in one or more of the serving cell or the at least one neighbor cell.
