The rapid development of wireless technology in Indonesia necessitates reliable network performance, particularly for mobile users. This study analyzes the performance of the Telkomsel 4G LTE network in Surabaya, focusing on key radio frequency parameters critical for service quality. The primary objective is to evaluate and optimize signal quality by assessing Key Performance Indicators (KPIs) based on data from vendor PT Nexwave. The methodology employs a drive test utilizing the Single Site Verification (SSV) approach. Data collection and analysis for Reference Signal Received Power (RSRP) and Signal to Interference plus Noise Ratio (SINR) are conducted using Genex Probe and Genex Assistant software. Optimization efforts resulted in significant improvements: the RSRP distribution meeting the -90 dBm threshold increased from 71.8% to 96.54%. Similarly, the SINR parameter achieving above 12 dB improved from 81.45% to 90.77%, exceeding the 90% KPI target. The study concludes that the SSV-based drive test and optimization successfully enhanced network performance. The final results show RSRP and SINR conformance at 96.54% and 90.77%, respectively, closely approaching the 100% optimization success requirement set by the operator and vendor.
