摘要

Delivering reliable and high-capacity Internet connectivity to high-speed train users is a challenge. Modern railway cars act as Faraday cages, and a typical train comprises several hundreds of users moving at high velocity. Furthermore, with the global availability of 4G LTE, user expectations have dramatically increased: it is expected to be online anytime and anywhere. Demand for high-capacity mobile is being driven by video and music streaming services, for lower latency and higher availability by gaming, and for more reliability and even uplink capacity by mission-critical applications. Finally, the life cycle of the railway industry is much longer than for telecommunications, which makes supporting 5G challenging. In this article, we survey the challenges associated with delivering high-capacity connectivity to train users, describe potential options, and highlight how a leading western European operator is tackling these challenges and preparing for 5G and beyond.
