Shanghai chosen to pioneer commercial CBTC over LTE
CHINA: Specialist telecoms company Huawei is currently testing an application of CBTC over LTE on Line 5 of the Shanghai metro with a view to launching a commercial version on Line 6 in the future. This follows a pilot application in France after Huawei signed a Memorandum of Understanding with Alstom in 2014. The French company provided a train and onboard technology for the pilot project on its test track at Valenciennes and Huawei supplied the eLTE infrastructure.
At InnoTrans 2016 Huawei rolled out a next-generation urban rail data communication system and a cloud-based traffic control integrated automated system developed with Chinese partner company Hollysys in which a cloud platform is deployed in the operations control centre. The data communication system featuring eLTE anti-interference design, seamless dispatching and high scalability was developed jointly with Thales; use of LTE base stations with a large coverage area reduces the number of devices that need to be installed in tunnels.
Yuan Xilin, President of the Transport Sector of Huawei’s Enterprise Business Group, said that China’s Urban Rail Association had agreed that LTE should be used on all new metro lines in the future. Its application in China had already generated considerable interest, he said. ‘Today, powerful technologies are rebuilding the transport industry. Using LTE, cloud computing, and big data technologies, we enable customers to achieve safe train dispatching and visualised management.’
Huawei is also working on a contract for uninterruptible power supplies for stations on London Underground.
