Study of a Millimeter Wave Communications System for Railway Trains

In recent years, aiming to achieve large-capacity radio communications between wayside equipment and onboard equipment in the field of railways, development of millimeter band radio communications based on the 40 GHz band has been proceeding. The millimeter band radio communications system is expected to realize faster communications. Especially in tunnel sections, it has the possibility to realize longer intervals between base stations than those along open sections because reflection waves to the wall are combined. In this paper, the authors report the test results and future feasibilities through propagation tests conducted using actual rolling stock and maintenance cars on Shinkansen tracks, aiming to obtain fundamental data for the radio system design.
