1 One Network Replaces Multiple Networks in Subway Communication Zhengzhou Subway China Challenges: No real-time video surveillance in the carriages Broadcast information can’t be transmitted No trunking system for quick response to emergencies Solution: Real-time video surveillance and broadcast in the carriages PIS and video monitoring within one LTE network Support for trunking service and train control through future software upgrade Benefits: Guaranteed security and status monitoring in carriages Distribution of all types of media information including advertisements Zhengzhou Metro Line One is a rapid transit metro serving urban and suburban districts. Length 26.1 km, a west-east line starting from new university campus and ending in Muzhuang.

2 TD-LTE Selection and Project Implementation Processes August 2011: Department of Industry And Wireless Bureau of Zhengzhou Province approved Zhengzhou Metro Co., Ltd. to use the frequencies from 1,795 MHz to 1,805 MHz to 2012: Design institute determined detailed technical solutions. 2012: Tenders for commercial telecommunications equipment, train, and PIS equipment used in train and on ground, as well as TD-LTE equipment were complete. 2013: Equipment for TD-LTE installed in Metro line 1 in Zhengzhou. 2010: Experts exchanged opinions on WLAN, WiMAX, RailView, TD-LTE, DVB-T, MESH, and other technologies for wireless telecommunications. Oct-Nov 2011: Research carriedout on companies developing wireless communication technologies. Marc 2011: Zhengzhou Rail Transport Wireless Telecommunications Expert Consultation was held.
