Optimizing Telkomsel’s 4G LTE Network Performance in Serpong District South Tangerang

Abstract

Serpong District, South Tangerang City, is a densely populated urban area that requires reliable, high-performance 4G LTE network services. However, field measurements indicate that several areas still experience poor signal quality (bad spots), which affect user experience and network reliability. This study aims to analyze and optimize Telkomsel’s 4G LTE network using the Automatic Cell Planning (ACP) method. The optimization is conducted using drive test measurements with G-NetTrack Pro to identify bad spots, followed by network simulation using Atoll based on existing site data. Optimization is performed through antenna parameter adjustment, namely tilt and azimuth, and evaluated using a before-and-after comparison. Network performance is assessed using Key Performance Indicators (KPIs), including Reference Signal Received Power (RSRP), Signal-to-Interference plus Noise Ratio (SINR), Download Throughput, and Shannon-based Cell Capacity. The results show improvements in RSRP, SINR, and cell capacity after optimization, while throughput remains stable and meets KPI requirements. This study contributes an integrated LTE optimization approach based on ACP that combines antenna parameter optimization and multi-KPI evaluation, including cell capacity using the Shannon model, in dense urban environments.
