Abstract

The growth of cellular telephone subscribers experienced a significant increase compared to other industries. With large and widespread number of subscribers, many operators have established new Base Transceiver Stations (BTS) to keep up with the increase number of subscribers. However, the addition of BTS is not a total solution to offset the increase number of subscribers. The purpose of this study is to analyze the signal quality, coverage area and network repairs by using physical tuning method. In Telkomsel operator drive test data in Minangkabau International Airport area, the RSRP parameter obtained an average sample data area around the site in the range -110 to 0, with a red indicator of 3.35%, an orange indicator of 18.96% and a yellow indicator amounted 36.3%. In this way, this research optimizes physical tuning method, including Re-azimuth which successfully directs the antenna to the badspot area, then changes the height of the antenna which makes it covered farther and tilting the Antenna which succeeds in making the coverage area more optimal. For the next bad spot area, optimization should be done in real time in the field so that the improvement can be resolved properly.

Abstract

The increase in network traffic is caused by an imbalance between the number of users and the provision of network capacity, causing the decrease of network performance. This is often found in densely populated areas with a large number of users so that the use of cellular access services is fairly high. For this reason, it is necessary to optimize the network, one of which is by replacing existing devices (swap). Site 31140_Lubuk Bukit, Pauh District, Padang is one of the base stations that has a performance issue, which has a low throughput value (±5Mbps) and a high traffic value of 83 GB/day with Flexi Multi Radio device type and sectoral antenna. Therefore, the existing equipment is replaced, from the FMR type to the Airscale type which minimizes the use of sectoral equipment and antenna types (3 sectors) to multisectoral (6 sectors). The measurement process is carried out using two methods, namely the COST-231 propagation model for the frequency of 1800 MHz and the Stanford University Interim (SUI) for the frequency of 2100 MHz then the Key Performance Indicator (KPI) parameters with the parameters of accessibility, retainability, integrity, mobility, usage, propagation loss and receive power. The results showed that the optimization carried out by the swap method could improve the site's performance, namely a decrease in traffic reaching 31.42% and an increase in throughput up to 60% and followed by an increase in other parameters that have met the threshold value.

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.

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.
