Siemens has received an order from the Nanjing Metro Corporation to equip a 52-kilometer line with the Trainguard MT automatic train protection system for the Nanjing-GaoChun LuGao section. Siemens will be using LTE (Long Term Evolution) radio technology for the first time here in order to transfer mass data in real time. The line links six stations in the Gaochun district in the south with the center of the megacity. Following commissioning at the end of 2017, trains will run at a top speed of 120 km/h on this stretch. The introduction of the mobile radio standard Long Term Evolution (LTE) is the next stage of mobile communication, and offers better performance than WiFi. As the communication transfer technology between train and line for CBTC (Communication-based Train Control), CCTV (Closed Circuit Television) and passenger information LTE has advantages such as greater data bandwidth, service quality assurance for multiple services and higher interference suppression performance.
