Abstract

Saat ini operator telekomunikasi masih melakukan upaya untuk meningkatkan kinerja layanannya. Salah satu metode untuk mengetahui kinerja layanannya ialah dengan melakukan pengukuran kualitas sinyal secara langsung atau biasa disebut drivetest. Drivetest ini dilakukan dengan cara mobility dan menggunakan metode Single Site Verification (SSV) yang dilakukan untuk menverifikasi setiap site apakah dalam kondisi bagus atau tidak. Throughput adalah jumlah informasi yang berhasil dikirim per satuan waktu. Physical Cell Identity (PCI) merupakan kode angka yang membedakan setiap cell atau sektor pada jaringan 4G LTE. Dalam penelitian ini pengukuran kualitas jaringan 4G LTE Indosat berdasarkan parameter Throughput dan PCI sebagai parameter utama yang diamati, lalu parameter SINR, RSRQ dan RSRP sebagai parameter pendukung. Pengukuran kualitas throughput jaringan 4G LTE Indosat untuk site 01JKS504 bisa dikatakan sangat bagus. Hal ini dapat dilihat dari nilai tiap parameter yang diperoleh dari drivetest. Pada parameter Throughput sudah memiliki nilai yang sangat bagus dengan indikator KPI berwarna biru(10.000 sampai 100.000 Kbps) untuk coverage area disekitar site. Pada parameter RSRP sangat baik (-80 sampai 0 dBm) dan RSRQ memiliki nilai yang sangat bagus dengan indikator KPI dominan berwarna biru(-10dB sampai 0 dB) untuk coverage area disekitar site. Pada parameter SINR memiliki nilai yang kurang bagus dengan indikator KPI berwarna kuning(0 sampai 13 dB) untuk coverage area disekitar site.

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

Broadband wireless access technology has taken the lead in communication technology development, enabling users to communicate with fast data speeds and extensive coverage.. Problems that frequently arise in mobile communication systems are the wide range of services and the level of network service quality. Thus, optimization is carried out to improve network quality in the Lubuk Kilangan area by using the drive test method to determine the quality of the network and bad spot areas and analyzed using terms discovery software. The reason behind the findings of this study is that the optimal link budget value for 4G LTE infrastructure in Lubuk Kilangan is higher than the current industry standard due to the unique characteristics of the area. According to the analysis and calculation of the link budget, power additions, and antenna tilting alterations were carried out for optimization. The power quality of the RSRP parameter increased from the fair (orange) area of 2.58 to 0.29. For the SINR parameter, For the SINR parameter, there was also an increase in quality at poor category locations in the KPI parameters (Range RSRP) locations from 0.08% to 0.05%, resulting in SINR bad spots decreasing. The proportion for Throughput after optimization remains the same, at 100%. Indicating that there had been a good increase in the coverage area, making the coverage in the Lubuk Kilangan area good. It is necessary to conduct a deeper study by comparing several types of antenna orientation, including tilt, depending on various factors such as the deployment scenario, coverage requirements, interference considerations, and the specific characteristics of picocells, femtocells, and repeaters. Future research could explore the impact of other factors, such as network topology and user behavior, on link budget optimization of 4G LTE infrastructure in different contexts
