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.

4 High performance, high availability, and zero interference for HD passenger service High bandwidth (20+ Mbit/s) fulfilling PIS requirements and future evolution. Zero interference with dedicated frequency band, high bandwidth facilitates unified multi-service carrier. Distributed eNodeBs reduce number of sites and handovers. Lower cost by utilizing leaky cables of public communication systems. Meets EN61373 and EN50121 railway standards.

5 Network planning and special scenario designs 1 st Scenario: Conventional tunnel Feature: Conventional closed section BBU in station equipment room and RRU in tunnel to cover 1.2 km. If distance is longer than 1.2 km, a site will be deployed inside the tunnel. 2 nd Scenario: Tunnel portal Feature: Multiple railways in a tunnel Cell coverage is extended to U- Groove then handed over to the next cell in order to avoid service interruption. 3 rd Scenario: U-Groove Feature: No handover between tunnels Panel antenna and leaky fibers share RRU, U-Groove coverage is provided by panel antenna at tunnel portal to avoid handover.
