Initially, Zhengzhou Metro will use LTE for the transmission of CCTV signals and passenger information data, but the supplier Huawei says will start experimenting with LTE for the new line's communications-based train control (CBTC) system with a view to adopting it for telecommunications by the end of next year.
The objective is to provide bilateral radio transmission channels for train-to-ground voice, data and video transmissions, which Huawei says will improve communications and operational efficiency compared with traditional segregated transmission networks.
The first phase of the 32.8km east-west Line 1, which opens later this month, will be 26.3km long, and will be operated by a fleet of six-car trains supplied by CSR Zhuzhou.
