Wireless Technology Takes Off in Asia

Wireless networks are proving to be an extremely popular data transmission means as greater demands are placed on railway communication systems by new technologies. Using public transportation in Asia's rapidly growing cities as examples, the authors discuss how, under even the most challenging conditions, an array of applications can be supported by wireless networks. Significantly greater bandwidth is needed. Operating as communication-based train control systems, moving block train control systems are increasingly being used. Another example is on-board CCTV surveillance using a control center and cameras. Passenger information system use is increasing. Platforms, in addition to being suitable for demanding railway environment operations, able to communicate, even with fast-moving trains, with high availability, a wide usable bandwidth, and without interruption, must have the ability to prioritize safety data streams and signaling transmissions, synergistically utilize, for various applications providing all applications with a large cumulative bandwidth, different radio technologies, and use, at the same time, very different communication requirements to support a number of applications.
