COMPARATIVE ANALYSIS OF THE CONCEPT OF CREATION AND DEVELOPMENT OF 5G/IMT-2020 NETWORKS IN RUSSIA, CHINA, USA AND EUROPE

Abstract

This article raises the question of the prospects for the development of 5G networks in Russia, China, the United States and Europe. Currently, there are four distinct generations of cellular communication in the world and in Russia. The development of each subsequent generation of communication as technical and economic capabilities improved and the spread of dominant standards occurred approximately every 10 years. The research community and industry in general agree that in the future it is impossible to meet future mobile traffic demand and application requirements simply by evolving the current fourth generation architecture. Instead, there is a need for a significant overhaul of the mobile network system: such an effort is commonly referred to as the future fifth generation (5G) architecture, and large-scale initiatives have been launched around the world to address this issue. The research community has already invested a very significant effort in identifying new individual technologies. The fact that all new offerings are labeled 5G has created a lot of confusion about what 5G really is. The purpose of this article is to shed light on the current state of the definition of 5G architecture and trends in the required technologies in Russia, the United States, China and Europe. Key contributions are: (1) analyze the 5G requirements defined by various global initiatives, highlighting the similarities and differences in 5G network development in Russia, China, the United States and Europe; (2) discuss current technology trends showing that there is broad consensus on the key factors driving 5G development in these countries; (3) strive to understand the new concepts that need to be developed with assistive technology to meet the desired requirements.
