- ДокументBasic technologies and techniques ML/AI for improving physical layer security for 5G/6G communications systems(2023) Tsopa, O.; Dudka, O.; Merzlikin, A.One of the main features of using the millimeter wave band in the deployment of 5G/6G technologies is that these waves have a narrower range and less ability to penetrate obstacles such as buildings and trees [1,2]. Therefore, millimeter waves require a larger number of communication nodes located closer to each other to ensure network coverage. In addition, due to the high frequency of millimeter waves, they are subject to greater signal scattering and absorption from surfaces such as building walls and other obstacles, which can result in reduced data transmission range. Therefore, it is necessary to consider engineering solutions and technologies of artificial intelligence (IA) and machine learning (ML), which will allow ensuring high-quality communication between communication nodes, taking into account the peculiarities of the millimeter range of radio waves. However, thanks to the high bandwidth of the millimeter wave band, 5G/6G technology can provide high-speed transmission of large amounts of data, enabling new applications and services such as virtual reality (VR), augmented reality (AR), augmented reality (XR), Internet of Things (IoT) and others. Therefore, using the millimeter range of radio waves is an important element of 5G/6G technology that requires specific solutions to ensure reliability and security at the physical level of the network.
- ДокументEstimation of the Bandwidth of the Communication Channel of 5G Networks Based on Small Cells(2021) Tsopa, O.; Dudka, O.; Merzlikin, A.; Ruzhentsev, N.The article is devoted to the problem of using 5G millimeter waves band (MM WB) in wireless communication systems of the next generation. The aim of the work is to clarify the calculation methods and estimate the availability parameters and performance of communication channels in the millimeter wavelength band when deploying 5G communication network segments in various climatic zones of Ukraine.
