Abstract

This paper proposes effective methods and means to enhance the quality of mobile communication and mobile Internet in high-speed trains. The current issues related to achieving enhanced mobile communication and Internet quality in high-speed trains are discussed within this thematic scope. The practical research examines the metrological features of the proposed new combined methodologies for improving mobile communication and Internet quality in high-speed trains at a model-complex level. It has been established that the methodology combining methods (LTE + Wi-Fi + 5G) shows the best results due to the combination of low-latency and jitter technologies. Metrological measurements confirm its effectiveness through lower latency and jitter values compared to other methodologies. Methodology 3 (5G + Micro-grids) offers high local indicators but is limited in bandwidth. Metrological data confirm the reduced latency and jitter.
