Abstract

Technological progress is currently experiencing very rapid development where mobile communication systems are technologies that support seamless communication links. When the user equipment is within range of the eNodeB, factors such as the distance between the user equipment and the eNodeB will affect the signal performance received by the user equipment. In this study, we analyzed the effect of the distance between user equipment and eNodeB on RSRP and SINR values on LTE 1800 MHz technology. The method used is the measurement of the drive test and the calculation of the Link Budget and the Propagation Model. The results and analysis show irregular changes in RSRP and SINR values caused by varying obstacle factors in the propagation environment. According to the calculation results of the Link Budget and the Propagation Model on the research object, it was found that the RSRP and SINR values decreased for every 100 m change in distance from the eNodeB. Based on the comparison, it is obtained that the PCS Extension to Hatta propagation model is close to the drive test measurement results.

Abstract

The fourth-year students of Bachelor of Applied Studies (BAS) Software Engineering Technology Department of Information Technology (IT) Politeknik Negeri Padang (PNP) are required to work on the Final Project Proposal to the Coordinator, to deliver to the expertise group team to assess the eligibility of the topic. The expertise teams consist of the same skill family. The assessment criteria include originality, novelty, target and topic contribution, methodology, and similarity. Therefore, a system to support group decisions is highly needed to get eligibility for the topic. In a pandemic like today, indoor gatherings are severely restricted. The work from home policy also limits the movement of the team to gather together so that the expert team who would judge cannot conduct a meeting to determine the feasibility of the final project topic optimally. The existence of a subjective assessment of a particular topic requires discussion from the team. The simple Additive Weighting (SAW) method was used to rank the final project proposal, and BORDA method was used to Accumulate the assessment score of the expert team. The research revealed the recommendation on students’ final topics. Testing is done by testing the sensitivity of the criteria used in a decision maker's preference. The final result of this research is a recommendation of a final project that is feasible to be implemented by students and recommendation for sensitive assessment criteria. From the ten topics of the final project that were assessed, seven topics could be accepted. The sensitivity test results showed that the weight with criterion 1 and criterion 4 significantly affect the assessment results.

Abstract

The development of communication technology, especially 4G LTE, has driven an increase in the need for high-speed internet services in all regions, including rural areas such as Tinombo District, Parigi Moutong Regency, Central Sulawesi. However, geographical conditions dominated by hills and bays cause the quality of Telkomsel's 4G LTE network in this region to vary and is not fully optimal. This study aims to analyze the performance of Telkomsel's 4G LTE network in Tinombo based on Key Performance Indicator (KPI) parameters which include Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and Signal to Interference and Noise Ratio (SINR). The method used is a drive test with the G-NetTrack Pro application on mobile devices, covering field measurements from Tinombo Village to Sipayo Village, Sidoan District. Data is obtained through real-time signal recording configuration, with support for routing and location of Base Transceiver Station (BTS) using Google Earth Pro and Cell Mapper. The analysis was conducted to evaluate the signal strength, signal quality, and interference level on Telkomsel's 4G LTE network. The results of the study are expected to provide scientific information related to the actual condition of 4G LTE network performance in rural areas, as well as become a reference for service providers in optimizing network quality. This research is also relevant for academics, researchers, and telecommunication practitioners, especially in the field of Radio Frequency Engineering, in understanding the technical challenges of network implementation in areas with complex topography.

Abstract

The deployment of 5G New Radio (NR) networks requires substantial infrastructure investment, posing challenges for emerging markets. This empirical study explores coverage optimization by retrofitting existing 4G LTE Base Transceiver Stations (BTS) using machine learning-enhanced Self-Organizing Network (SON) algorithms. Over six months, 6,895 drive test measurements were collected across 28 Telkomsel BTS sites in Padang, Indonesia, enabling before-and-after optimization analysis. Paired t-test results showed significant improvements in coverage quality: the service area with excellent SINR increased from 54.5% to 58.1% (p < 0.001, Cohen’s d = 0.27), while maintaining 99.3% RSRP compliance (≥ -92 dBm, 95% CI: 97.8%–100%). Automatic Cell Planning (ACP) effectively identified parameter configurations that enhanced performance without additional infrastructure cost, reducing deployment expenses. However, 5G NSA deployment remained limited to only 2.17% of measurements, which is valid for early-stage insights but restricts generalization to full 5G deployment scenarios. Therefore, the findings primarily apply to NSA overlay on existing 4G infrastructure rather than full 5G standalone deployment. This underscores ongoing economic and technical challenges in emerging markets’ 5G rollout. Despite this, the study provides strong empirical evidence supporting infrastructure reuse via SON-based optimization as a cost-effective way to improve coverage and quality. These results offer valuable guidance for operators and policymakers aiming to accelerate 5G adoption while managing costs in similar regions. Future work should expand validation as 5G NSA and standalone (SA) deployments grow and investigate integration with advanced AI-driven network management techniques

Abstract

This study examines the optimization of Fiber To The Home (FTTH) network design using the Gigabit Passive Optical Network (GPON) architecture through a geographic mapping approach between customer houses and Network Points (NP). The background of this research lies in the inefficiency of conventional FTTH design in rural areas where house distribution is irregular, often causing excessive cable usage and higher optical attenuation. The objective of this study is to compare a conventional design scenario, where NP placement follows the feeder route, with an optimized scenario that assigns each house to the nearest NP based on geographic proximity. A comparative design analysis method was applied using field observation data, estimated block dimensions, and visual network mapping. The findings indicate that the geographic mapping approach significantly reduces total cable length by 2,586 meters, primarily from shorter drop cables, resulting in a more organized cable layout and easier network maintenance. This optimization also implies lower material usage, reduced attenuation, and better network scalability. The results demonstrate that nearest-distance-based design provides a practical and efficient solution for FTTH deployment in rural environments with non-uniform house patterns.
