Abstract

The era of fifth-generation mobile or wireless networking technology has just begun, and it is this technology that can actually improve system performance to an extremely high level. Mobile communications from space are evolving rapidly. Non-terrestrial networks have the ability to provide reliable connections to areas that were previously difficult to connect, which has a high impact on the economic situation. A non-terrestrial network with 5G support can be an effective solution for providing services anywhere and anytime and expand the coverage area. This paper analyzes possible solutions for satellite systems and multi-beam data technologies due to their ability to increase bandwidth through frequency reuse, as well as increase data rates. To adapt 5G to support non-terrestrial, you need to consider and explore a holistic architecture or design that can cover many areas and users. The article analyzes and explores the main aspects of non-terrestrial networks, analyzes in detail the design possibilities, problems of implementation and construction, as well as areas of research. Fifth generation (5G) technologies and systems will meet the needs of users around the world anywhere, anytime. Extraterrestrial Network (NTN) systems are able to meet connection requests anywhere, offering a wide coverage area and ensuring continuity, availability and scalability of services. In this article, we will look at NTN's capabilities and its potential to meet the expectations of users on and off 5G networks. The current situation, current research and unresolved issues underscore the importance of NTN in the field of wireless communications.

Keywords: 5G, non-terrestrial network, high-altitude platform systems, HAPS, network architecture, satellite access.
