Abstract
High-Speed Railway (HSR) has brought much convenience for peoples’ travelling. To ensure safe and reliable operation of HSR, maintaining a reliable bidirectional communication link between the train and the ground, dedicated mobile communication systems such as GSM for railway (GSM-R) and LTE for railway (LTE-R) play key roles. Moreover, rapid growth of future railway services and applications such as real-time high-definition (HD) video surveillance has aroused 1 GBps data transmission rate with 100 MHz bandwidth at least. Thus, higher frequency band such as mm-wave technique, the fifth generation (5G) technique and corresponding mobile communication network should be designed accordingly to provide high capacity and high data transmission rate for newly developed railway services and applications. This presentation talks about some key features and technical challenges on dependable wireless communications for high-speed railways.
