Abstract

Network interference such as overshoot can affect differences in signal quality and strength on cellular networks. Overshoot is a situation where the network power coverage exceeds the initial planning limit, causing users to be served by cells that are further away than the closest cells. This research aims to deal with problems that arise due to overshoot in the East Sawahan area. The research was conducted using the drivetest method in East Sawahan, Padang. The software used is TEMS Pocket for collecting measurement data and TEMS Discovery software for processing drivetest result data. Network performance is seen from the RSRP, SINR and PCI parameters. In this problem, network performance was improved using Atoll software. With the antenna tilting method which was previously 0? increased to 6?, the improvement results show that after making changes to network performance the signal quality meets the results of the KPI standards.

Abstract

Technology in the telecommunications sector continues to develop. One of them is the Multiple Input Multiple Output (MIMO) antenna used in WIFI access oint application using MIMO technique in enhancement the need to transfer large amounts of data. In the design and manufacture of MIMO antennas for WIFI access applications point with dimensions of 110 mm x 112 mm using FR-4 substrate specifications with a thickness of 1.6 mm. The antenna consists of four ports and is at each corner The groundplane has four slots to achieve good isolation and produces good bandwidth. The antenna simulation produces a bandwidth of 1.0516 GHz with frequency 2.4 GHz, return loss -12.78 dB, isolation -16.08 dB, and VSWR 1.53 dB. Meanwhile, manufactured antennas produce a bandwidth of more than 100 MHz with frequency 2.4 GHz, return loss -13.5 dB, isolation -18.8 dB, and VSWR 1.29 dB. Antenna simulation using the CST Studio Suite 2019 software application. In the application of the antenna used for Wi-Fi as a transmitter By comparing distances, different results are obtained where the power value is Each distance is different because the farther the distance, the greater the power value produced or emitted will be smaller or less optimal  network.

Abstract

Video streaming merupakan salah satu layanan untuk mempercepat penyebaran informasi pada waktu yang bersamaan secara langsung. YouTube menjadi salah satu platform yang menyediakan layanan video streaming. Untuk mengetahui kualitas jaringan 4G LTE pada layanan video streaming dilakukan pengamatan dengan metode drive test menggunakan aplikasi TEMS Pocket dan TEMS Discovery pada daerah Lubuk Minturun, Kota Padang. Hal ini bertujuan untuk mengetahui performa sinyal operator Telkomsel berdasarkan parameter RSRP, RSRQ, SINR, dan Troughput. Hasil penelitian menunjukkan kualitas sinyal 4G LTE daerah Lubuk Minturun parameter SINR >0 dB terdiri sebesar 61.72% dengan 395 sampel, RSRQ > -15 dB dengan persentase 64.38% dengan 412 sampel, dan RSRP > -100 dBm terdiri atas 100 sampel dengan persentase15.63%. Hasil pengukuran data Troughput didapat 640 sampel dengan 72 sampel yang melebihi > 2000 kbps dengan persentase sebesar 75.64%. Dengan demikian, data parameter-parameter tersebut belum memenuhi standar KPI Telkomsel.

Abstract

Ultra Wideband (UWB) technology is an unmodulated wireless digital communication system that uses an extremely short duration pulse to transmit information bit. Because of this pulse, the UWB system needs a very wide bandwidth. Federal Communication Commission (FCC) has regulated the 3.1 – 10.6 GHz frequency spectrum for UWB. Since FCC released this frequency, many research in telecommunication have been done on UWB systems. One of them is a development of an Antenna that is suitable for UWB devices. UWB antenna characteristics require FCC band, omnidirectional radiation pattern, and compact size. In order to meet these needs, an antenna with a simple structure in the form of a monopole patch antenna with a similar patch size and ground width has been designed. The antenna is built on an FR4 – epoxy substrate material, with 4.4 dielectric constant and 1.6 mm thickness. The antenna feeding structure consists of two 100 Ω and 50 Ω lines with a wideband impedance matching scheme using tapered side and tapered transformers. The antenna design and optimization processes are conducted using electromagnetic simulation software, and measurements are carried out in an anechoic chamber. Simulation and measurement results show good agreement, and the antenna can work at frequencies 3.5 - 11.3 GHz with a gain of 1.5 – 3.25 dBi and stable omnidirectional radiation patterns. The antenna has dimensions of 27 × 8 × 1.6 mm, which are smaller than the antenna reported in the last research and suitable to be applied on various UWB devices.

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
