Overshoot analysis based on user equipment metrics
User equipment (UE) can include a network analyzer to capture network metrics to monitor conditions of cell coverage and coverage overlap. In some instances, the UE is served by a neighboring cell located further away instead of the nearest cell due to coverage overlap. The UE can capture data representing network metrics and can report such data to a network device to further aggregate the data and to generate reports. The network device can use the aggregated data to perform overshooting analysis, which may include determining transmission power of neighboring cells that overlap with coverage of a target cell. The aggregated data may be used to determine an overshoot index for a cell. A cell with high overshoot index may be designated an overshooter cell. The parameters of an overshooter cell may be modified to reduce interference between cells.
