Initial tuning complements the Radio Network Design. It is performed when all nodes in a cluster are operational but not yet in commercial use. The analysis of the log files from drive - and stationary tests improve both network coverage and capacity. When the radio network has been tuned and there are sufficient subscribers generating traffic, the live network can be optimized in order to identify and solve possible issues. The Drive test is performed to find the effectiveness of RF conditions in wireless and mobile environment. In real "drive-test" these conditions are more appropriate with focus on different environment. This helps to check the actual coverage and quality of the network for the user. Through this paper we will learn that what effective etilt of antenna we needs to consider during the initial tuning optimization and what the effects are of Etilt changes on bad coverage, Reference Signal quality, Signal to Interference Noise Ratio, Channel Quality Indicator, Modulation Coding Scheme and bad throughput area. So that before commercial launch at least 90% of the coverage has been met. Also we are ensuring that every antenna has the most optimal combination of mechanical and electrical down tilt which is one of the most essential objectives of entire initial tuning.
