Abstract

The Voltage Standing Wave Ratio (VSWR) serves as a comparative measure between transmitter and receiver voltages, impacting site transmit power. VSWR values at a Radio Base Station (RBS) are evident in feeder cable losses, jumpers, combiners, and radio antenna losses. This study aims to assess the impact of poor VSWR values on BTS transmit power and perform troubleshooting analysis on 4G signal quality and Coverage Area. The study commenced with a literature review and VSWR measurements in the Gurun Laweh Aia Pacah region. The process involved identifying VSWR issues at the BTS site, conducting a Drive Test using pocket Tems, and troubleshooting the VSWR problem. Drive Test findings encompassed areas with weak signals, BTS site data, and problematic spots. The analysis utilized applications like Tems Discovery and MapInfo Pro. Results along the Gurun Laweh Aia Pacah road showed signal strength affected by a high VSWR value of 1.6. RSRP data rated 50% in the good category, SINR at 31% in the good category, and throughput at 5% in the good category. Elevated VSWR values diminish signal range, subsequently impacting traffic metrics. Immediate VSWR troubleshooting becomes imperative; low VSWR promotes higher transmit power efficiency, while normal VSWR ensures optimal transmit power efficiency.

Abstract

The increasing complexity, heterogeneity, and large-scale nature of modern telecommunication networks require a monitoring mechanism capable of ensuring continuous network performance and service availability. Although modern approaches such as streaming telemetry and network observability provide higher data granularity, Simple Network Management Protocol (SNMP) remains widely used due to its lightweight design, standardization, and multi-vendor compatibility. This study aims to analyze the role of SNMP in monitoring network performance and availability in telecommunication systems. The research employed a structured literature review approach by collecting, selecting, and synthesizing relevant studies published within the last five years. The results indicate that SNMP remains effective for monitoring key performance parameters, including throughput, latency, packet loss, CPU utilization, interface status, uptime, and fault notifications. Its major strength lies in supporting interoperable monitoring across heterogeneous multi-vendor infrastructures. However, limitations were identified in terms of polling scalability, data granularity, and real-time traffic visibility in modern cloud, SDN, edge, and IoT-based environments. This study concludes that SNMP remains strategically relevant as a baseline monitoring layer and is most effective when integrated with streaming telemetry in a hybrid monitoring architecture.

Abstract

This study presents a literature review on ranking-based performance indicators in the evaluation of 4G LTE cellular networks. Conventional network performance evaluation commonly relies on Key Performance Indicators (KPIs) such as throughput, latency, and packet loss, which are typically assessed using average values. However, this approach often fails to represent the performance experienced by users under worst network conditions. Therefore, this study aims to analyze and highlight the role of ranking-based KPIs, particularly Rank2%, in providing a more representative evaluation of network performance. The research employs a structured literature review method by analyzing relevant journal articles from reputable databases published in recent years. The results show that ranking-based KPIs are more sensitive in capturing extreme conditions, especially for users experiencing the lowest quality of service. In addition, these indicators are closely related to Quality of Experience (QoE), as they better reflect user-perceived performance. This study concludes that integrating ranking-based KPIs with conventional metrics can improve the accuracy and effectiveness of LTE network performance evaluation.

Abstract

Growing demand for data services is prompting mobile network operators to provide Long Term Evolution (LTE) networks that can balance service coverage with network capacity. This study analyses the impact of frequency band variations on the performance of 4G LTE networks operating at 900, 1800 and 2100 MHz in the Padang Timur sub-district. Atoll simulation was employed to evaluate the Reference Signal Received Power (RSRP) and Signal-to-Interference-plus-Noise Ratio (SINR) parameters, as well as throughput. Meanwhile, Monte Carlo simulation was utilised to analyse network capacity based on user distribution. The simulation results show that the 900 MHz frequency provides the best coverage performance, with the entire study area falling into the 'Excellent' category based on the RSRP and SINR parameters. However, service capacity at this frequency is relatively low, with a connected user percentage of 13.6 % in the Monte Carlo simulation. In contrast, the 2100 MHz frequency provided the best capacity performance, with a connected user ratio of 73.8 % and a cumulative application throughput of 1,104.06 Mbps. The 1800 MHz frequency demonstrated performance falling between the two frequency bands. The research results indicate a trade-off between coverage and capacity due to variations in frequency bands. Monte Carlo simulations provide a more realistic representation of user distribution than deterministic capacity dimensioning when evaluating network service capabilities. Based on these results, the 900 MHz frequency is better suited to providing coverage, while the 2100 MHz frequency is better suited to providing capacity in the study area.
