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.

The transition from analog to digital television broadcasting in Indonesia improves picture and sound quality; however, signal reception in rural areas remains a challenge due to long distances from transmitters and unfavorable topography. Conventional antennas and signal boosters have not provided optimal performance. This study aims to design a vertical linear antenna array with a stacking configuration to enhance digital television signal reception in the Ultra High Frequency (UHF) band. The antenna design was carried out through theoretical calculations, simulation, and optimization using CST Studio Suite 2019. The analyzed parameters include return loss, VSWR, gain, bandwidth, and radiation pattern. Simulation and testing results show that the antenna achieves a return loss below −10 dB, VSWR less than 2, gain above 10 dBi, and a unidirectional radiation pattern. The proposed antenna effectively improves digital television reception quality in rural areas.

The rapid growth of mobile data traffic in cellular networks has created significant challenges in maintaining network performance, particularly during peak usage periods known as busy hour. During these periods, high user density leads to increased traffic load, resulting in network congestion and degradation of key performance indicators such as throughput, latency, jitter, and packet loss. This study aims to analyze conceptually the impact of busy hour traffic on cellular network performance through a structured literature review approach. The method involves collecting and synthesizing recent studies from reputable journals to identify patterns and relationships between traffic load and network performance parameters. The results indicate that increased traffic during busy hour consistently causes resource contention, leading to decreased throughput and increased latency, jitter, and packet loss. Furthermore, this study reveals that most existing research is empirical and case-specific, lacking an integrated conceptual framework. Therefore, this research contributes by providing a comprehensive conceptual understanding of the causal relationship between busy hour traffic and cellular network performance degradation, which can support future research and network optimization strategies.

This study examines the transformation of telecommunication network architectures toward public cloud environments through a cloud networking approach. Although technologies such as Network Function Virtualization (NFV), Software Defined Networking (SDN), edge computing, and virtualization have developed rapidly, the integration of cloud networking architectures capable of supporting comprehensive multi-domain communication remains limited. This research employs a Systematic Literature Review (SLR) of publications from 2020–2024 to identify development trends, challenges, and research gaps in cloud networking architectures. The analysis indicates that multi-domain interconnection, particularly communication among cloud, edge, and virtual networks, remains a major unresolved challenge, while most studies still focus on optimizing individual components rather than comprehensive architectural integration. As its main contribution, this study proposes the Hierarchical Multi-Domain Cloud Networking Fabric (HM-CNF), integrating multiple communication mechanisms into a hierarchical unified system to enable more coordinated, scalable, and efficient multi-domain communication, supporting telecommunication infrastructure migration toward public cloud and providing a conceptual framework for next-generation cloud networking systems.

The advancement of cloud computing, virtualization, and distributed applications has increased the demand for scalable and high-performance data center network architectures. Traditional networks based on Virtual Local Area Network (VLAN) have limitations in terms of segmentation and efficiency, making them less suitable for modern data center environments. Therefore, Virtual eXtensible Local Area Network (VXLAN) combined with Ethernet Virtual Private Network (EVPN) as the control plane has emerged as a widely adopted solution. This study aims to analyze the scalability and performance of the VXLAN-EVPN protocol in data center network architectures. The method used is a Systematic Literature Review (SLR) by collecting and analyzing scientific articles from various databases within the period of 2021–2025. The results indicate that VXLAN improves network scalability through the use of Virtual Network Identifier (VNI), while EVPN enhances the efficiency of network information distribution using a Border Gateway Protocol (BGP)-based mechanism. In addition, the implementation of VXLAN-EVPN in a spine–leaf architecture is able to maintain network performance in terms of latency and throughput. Therefore, VXLAN-EVPN is an effective solution for supporting scalable and efficient modern data center networks.

This study aims to design and analyze the performance of Optical Line Terminal (OLT) and Optical Distribution Cabinet (ODC) devices in the Fiber to the Home (FTTH) network trainer module at the SKSO G316 Laboratory, Padang State Polytechnic. The research methods included design simulation using Optisystem software, physical implementation of the trainer module, and attenuation measurement using an Optical Power Meter (OPM). The results show that attenuation under normal core conditions (orange) is stable in the range of 14.94–16.23 dB, while core bending (green) and core damage (blue) conditions cause a significant increase in attenuation to 16.28 dB and 16.01 dB at a wavelength of 1310 nm. The length of the dropcore cable (10 m, 15 m, 20 m) showed an effect on the increase in attenuation with an additional attenuation increase of 0.9 dB per 5 meters. The simulation results and actual measurements are consistent with the link power budget calculations and meet the technical specifications with total attenuation below the maximum limit of -28 dB. This trainer module is useful as a learning medium for analyzing FTTH network performance and the impact of physical disturbances on optical fiber transmission.
