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

Abstract

4G networks were created to provide excellent service and fast data transmission. The goal is to promote better reception, maintain smooth data flow, and speed up information exchange. Indonesia has six mobile operators, each of which has the right to use the radio frequency spectrum to deploy mobile network services. The radio frequencies used are divided into 450 MHz, 850 MHz, 900 MHz, 1,800 MHz, 2,100 MHz, and 2,300 MHz. This research focuses on the comparison of 4G LTE network quality at 900 MHz and 2100 MHz frequencies. Data collection is done by conducting a drive test and using the dedicated mode method. The software that is utilized for data processing are TEMS Pocket and TEMS Discovery Device. The network quality of both frequencies is measured based on RSRP, SINR, and Throughput parameters. The results of network quality measurements were obtained for the 900 MHz frequency, namely, RSRP worth 79.54%, SINR worth 65.69%, and Throughput worth 37.65%. While the frequency of 2100 MHz, namely, RSRP is worth 82.1%, SINR is worth 76.84%, and Throughput is worth 72.18%. Of the two frequencies, the 2100 MHz frequency has a better value than the 900 MHz frequency.

Abstract

 Along with the development of the current era of globalization, human needs for telecommunications are also increasing, especially in the telecommunications sector. A technology called Long Term Evolution (LTE) was introduced, which is a fourth generation (4G) cellular network technology. LTE is capable of providing data transfer speeds of up to 100 Mbps on the downlink side and 50 Mbps on the uplink side. The growth in the number of telecommunications service users in Pariaman City has caused a decline in network quality, especially 4G LTE technology. Benchmarking (Comparison) of the quality of 4G LTE operator services is carried out by measuring, comparing, and analyzing the network quality (performance) of two 4G LTE operators in Pariaman City. The measurement process uses the drive test method with the G-Net Track Pro application to measure RSRP, RSRQ, SINR and Throughput in Pariaman City. The comparison results were obtained in Pariaman City for Telkomsel operators having network quality parameters RSRP with a percentage of 48.71%, RSRQ with a percentage of 61.11%, SINR with a percentage of 84.25% and Throughput with a percentage of 68.48% while Tri operators have RSRP values with a percentage of 59.74%, RSRQ with a percentage of 50.38%, SINR with a percentage of 85.68% and Throughput with a percentage value of 66.63%. In general, it can be concluded that Tri operators are included in the good category in terms of signal quality and integrity while Telkomsel operators are in the good category in terms of Coverage.
