The Difference of Strength and Quality Signal on cellular networks is affected by the traffic on cell and the shape of the region topology. One of the problems encountered in-service performance is overshoot caused by poor signal quality. Overshoot is a condition where a range of power exceeds the specified limits, till the MS (Mobile Station) is served by a distant cell and not from the closest cell. Overshoot occurs due to boosting power which aims to improve service quality when there is an increase in customer activity in the network cell. The antenna tilting method is an effective and responsive method to resolve overshoot problem since it can form cell coverage, cells identification, measure Rx and C/I (Carrier to Interference) levels.). The results showed that after tilting there was a change in cell identification from 5 cells to 3 cells. The value of Rx level increased from -92.8 dBm to -82.03 dBm for the 726-sector and -72.13 dBm to -70.27 dBm for the 727-sector, while the 725-sector remained unchanged. C/I value for 16 dB increased from 35.17% to 73.59%.
