Comparative Performance Analysis of 4G and 5G Cellular Network Technology in Indonesia: Case Study in the City of Jakarta

Telecommunications technology has developed very rapidly along with the increasing need and demand for various information and communication technology services. From the first generation (1G), it has now reached the fifth generation (5G) networks with various potentials and advantages from the previous technology generations. In Indonesia, 5G cellular networks have begun to be implemented recently at several important points in big cities such as Jakarta with the hope that the 5G networks can provide network performance and quality that far exceeds the previous 4G technology from the user's perspectives. However, there are still several obstacles in the implementation of 5G technology in Indonesia, including the limited frequency allocation and the small number of Base Transceiver Stations installed. This causes the performance and quality of the 5G network in Indonesia is still not optimal according to user expectations. Therefore, this study aims to compare the performance of 5G and 4G LTE networks in the city of Jakarta based on Signal Strength and Quality of Service (QoS) parameters. Data collection was carried out in the city of Jakarta, especially in the area around Monas, Pantai Indah Kapuk, and Kelapa Gading with the drive test method using operators Telkomsel and Indosat Ooredoo. The analysis based on the field measurement data show that the Signal Strength and Quality of Service (QoS) for the 5G network has a much better signal and service quality than the 4G LTE network. In addition, based on field measurement data, it shows that the network coverage for one Base Transceiver Station on the 5G network has a coverage radius of about (±) 1 km.
