Abstract

This report analyzes the Quality of Service (QoS) of 4G LTE networks from Telkomsel and XL operators in Painan, West Sumatra. Along with the rapid advancement of telecommunications technology, improving service quality is a top priority. This research uses drive test method with TEMS Pocket application to measure latency, jitter, packet loss, and throughput parameters. The analysis results show that Telkomsel has a higher throughput, reaching 4362 Kbps, compared to XL's 4013 Kbps. Latency for both operators was measured to be poor, at 1554 ms for Telkomsel which was slightly better than XL with 1677 ms. Jitter also showed similar results, with Telkomsel at 1554 ms and XL at 1677 ms. In addition, packet loss on Telkomsel was recorded at 0.021% and on XL at 0.14%, both of which fall into the excellent category. These findings provide insights for operators to improve network quality and overcome existing problems. Thus, this research contributes to a deeper understanding of 4G network performance in the Painan area and serves as a reference for the development of telecommunications infrastructure in the Painan area, especially Indonesia.

Abstract

Demand for mobile data services and people’s dependence on 4G LTE networks continue to increase. However, the quality of service (QoS) of this network still requires improvement, especially regarding the effect of QoS on throughput at specific frequencies. The research gap lies in the lack of indepth analysis of the impact of QoS parameters on network performance at frequencies of 2,100 MHz and 2,300 MHz. This study evaluates the effect of QoS parameters, such as delay, jitter, and packet loss, on throughput in 4G LTE networks at both frequencies. The research methodology uses an experimental approach with throughput, delay, jitter, and packet loss measurements in various network conditions. The results showed that delay (17.2174 ms to 37.0322 ms), jitter, and packet loss significantly influence throughput, ranging from 624.5 Kbps to 1,322.4 Kbps. The 2,100 MHz frequency tends to show better performance than 2,300 MHz. This study concludes that optimizing QoS parameters, especially delay and jitter, can significantly improve 4G LTE network performance. These findings provide practical contributions for mobile operators in improving network quality and customer satisfaction and open opportunities for further research on other frequencies or newer network technologies.

Abstract

Simulasi penggunaan protokol routing di jaringan Telkomsel merupakan langkah krusial dalam perancangan dan pengembangan jaringan yang andal dan siap menghadapi berbagai kemungkinan masalah dimasa ini ataupun akan datang. Perkembangan komunikasi sangatlah penting, terutama pada zaman teknologi modern saat ini. Layanan internet telah menjadi sarana pertukaran informasi bagi setiap orang. Secara umum, OSPF (Open Short Path First) adalah protokol yang paling banyak digunakan OSPF merupakan protokol routing yang didesain otomatis untuk dapat mengendalikan dan mendistribusikan informasi routing antar jaringan secara dinamis. OSPF dapat mendeteksi perubahan topologi jaringan dengan cepat dan mengembalikan routing ke konvergensi dalam waktu singkat. Pada penelitian ini dilakukan simulasi topologi jaringan Telkom dengan protokol routing OSPF menggunakan Cisco Packet Tracer. Packet Tracer digunakan untuk mensimulasikan desain jaringan dan mengidentifikasi perilaku jaringan menggunakan metode routing OSPF. Sebelum simulasi dilakukan, perancangan topologi jaringan dilakukan melalui 8 tahapan. Kemudian pada konfigurasi routing OSPF, Ada lima jenis paket yang digunakan, untuk mengetahui Paket Hello, Deskripsi Basis Data, Permintaan Status Tautan, Pembaruan Status Tautan, dan Konfirmasi Status Tautan. Dari hasil simulasi dengan topologi tree didapatkan bahwa topologi tree pada jaringan Telkom tetap dapat bekerja dengan mengalihkan ke jalur alternatif dengan waktu respon antara 5-31 ms. Meskipun satu komputer terputus, komputer lainnya tidak terpengaruh. Hal ini sejalan dengan teori topologi tree. Simulating the use of routing protocols on Telkomsel's network is a crucial step in designing and developing a reliable network that is ready to face various possible problems in the present or in the future. The development of communication is very important, especially in today's modern technological age. Internet services have become a means of exchanging information for everyone. In general, OSPF (Open Short Path First) is the most widely used protocol OSPF is a routing protocol designed automatically to be able to control and distribute routing information between networks dynamically. OSPF can detect network topology changes quickly and return routing to convergence in no time. In this study, Telkom network topology simulation was carried out with OSPF routing protocol using Cisco Packet Tracer. Packet Tracer is used to simulate network design and identify network behavior using OSPF routing methods. Before the simulation is carried out, network topology design is carried out through 8 stages. Then in the OSPF routing configuration, there are five types of packets used, to find out Hello Packet, Database Description, Link Status Request, Link Status Update, and Link Status Confirmation. From the results of the simulation with the tree topology, it was found that the tree topology on the Telkom network can still work by switching to an alternative path with a response time between 5-31 ms. Even if one computer disconnects, the other computers are not affected. This is in line with tree topology theory.

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

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.
