Technical capabilities and safe use of mobile communications 6G in railway transport

Abstract

The purpose of the study is to describe the technical capabilities and promising approach to the safe use of 6G mobile communications in railway transport. The study used risk management methods in railway transport in accordance with international experience. As a result of the study, information about future 6G networks was systematized, the advantages of their specific technical characteristics over 5G networks were demonstrated, and methods were proposed to ensure the safety and security of information messages transmitted in railway telecommunication networks. In the context of the technical description of 6G networks, the following issues are considered: assessing the quality of services provided (including using indicators of the quality of human physical experience), the use of radio frequencies and combating multipath propagation of signals (based on more advanced methods of multiple access and filtering), the use of more effective modulation and channel coding methods, development of antenna array technology with multiple transmitting and receiving antennas and the use of reconfigurable intelligent surfaces, functional network architecture (based on software-defined networks and network functions virtualization) and its physical implementation (through the construction of a space-terrestrial integrated network), the use of a new internet protocol (covering several levels of interconnection). In the context of ensuring the safety and security of transmitted information messages, the issues of identifying threats and possible countermeasures by implementing additional settings and functions of safety and security 6G networks are considered. The proposed approach allows us to justify the safe use of 6G mobile communications in railway transport.
