Abstract: This paper presents the effects and optimization impact of wireless signal loss for subscribers in Lagos state, using 3G as a study. This paper is aimed at analyzing network coverage data obtained through drive testing on the investigated area to detect coverage holes or area with poor coverage. The collected data showed significantly where the problems were via pre drive test and analysis was performed to proffer solutions to identified problems. This was later confirmed with a post drive test. The Key Performance Indicators (KPI) which include Receive Signal Code Power(RSCP), Energy per chip to noise ratio(Ec/No), Speech Quality Index(SQI), User Equipment Transmit Power(UE Tx Power), Active Set number of members were analyzed and showed significant improvement after optimization where necessary. The RSCP coverage quality showed an appreciable improvement from 40% to over 76% of good coverage after optimization. Results after the optimization reveals that the Call Setup Success Rate increased from about 96% to about 98% and the Call Drop Rate reduced from 0.664% to 0.62 % out of 940 and 493 total number of calls attempts made during the pre and post drive test respectively. Besides, areas with more than three active set which could result into pilot pollution were identified and corrected by adjusting of the parameter (tilt) of the antenna involved.
