emergent accidents to ensure passenger

safety and reduce loss

• Train control: No-man driving ensure

security

• Shorten the running interval of train, improve

efficiency

• Reliable wireless data transmission, end-to-

end QoS guarantee

PIS & Video surveillance

• Travelling information: Route, station

transfer, ticket price

• Entertainment Information: Weather

forecast, TV program, and advertisement

• Video Surveillance: Real-time monitoring

of carriage, driver’s cab, and railway to

improve safety

Broadband and high performance network to improve passenger satisfaction, dispatch efficiency

and operation safety

LTE technology – ideal wireless technology for video surveillance

Ultra Broadband to Support Colorful Multimedia Data Services

LTE offers several essential benefits for PIS & video surveillance:

Higher performance and capacity: more than 50Mbps in uplink and more than 100Mbps in downlink

Scalable frequency bandwidth : supports frequency bandwidth from 3MHz to 20MHz

Support both TDD and FDD modes: flexible uplink and downlink bandwidth control by applying TDD mode

Low transport latency: transport latency is similar with fix line access, around10ms

Based on LTE technology, eLTE provides an universal wideband platform which perfectly adapt

to demands of metro communication
