Report Example : 

Figure 2 - 43 Report Example Handover problemsAdd more neighbours on cell G00963, start with adding G07663, G0547 and G00492. Tune the existing neighbour relations e.g. G07661 and G00961.Remove or investigate the neighbour relation on cell G00712 with G00652. Areas with Interference Investigate if it is possible to reduce the coverage of cell G05001. Locate the cells that interfere with the cell and change applicable frequencies. Remove the neighbour relation with G05143.Check the interfered areas around site G0084 and G0759 and consider to downtilt the antenna on cell G00923. High congestion in 6 cellsHandover problem in C134ABTS alarms from site C112Interference in the shopping mall
