The rapid development of telecommunication technology is aligned with the increasing needs and demands of society. The 5G network is one of the telecommunication technologies currently experiencing significant growth. In Indonesia, the implementation of the 5G network has just begun in several major cities, including Bogor. The 5G network is expected to provide better performance and network quality compared to the 4G network from a user perspective. However, there are still several challenges in the implementation of 5G technology in Indonesia due to limited infrastructure, radio frequencies, and the uneven distribution of the 4G network. This has resulted in the performance of the 5G network in Indonesia not meeting user expectations optimally. Therefore, this study aims to measure the performance of 5G and 4G LTE networks in Bogor using Quality of Service (QoS) parameters and signal strength. The study was conducted in Bogor Tengah sub-district, around SMAN 1 Bogor, Hotel Salak The Heritage, Regina Pacis School, Dunkin Donut Pengadilan, and Taman Sempur. The provider used for measurement is Telkomsel, utilizing Wireshark and G-Nettrack Pro software. The results showed that Telkomsel's 5G network in Bogor is still not optimal in terms of quality and signal strength, which is not yet superior to its 4G network. This is supported by the fact that the 5G infrastructure uses 5G NSA, the tower locations are far from the test points, and the environmental conditions around Bogor city."
