Mass Transit Wireless Application Scenarios
High-speed driving and stable access: High speed (a maximum of 160 km/h) poses a big challenge to stable access performance of wireless networks in high-speed,
mobile scenarios
Broadband service and refined management and control: One network bears multiple services such as HD streaming media and voice dispatching. A wireless train-to-
ground communication network that provides large bandwidth and multi-service quality of service (QoS) guarantee is urgently needed.
Real-time surveillance and high-efficiency operation and maintenance (O&M): IT applications in the mass transit industry require simplified network architecture,
reliable devices, highly efficient network management to improve O&M efficiency.
Modern mass transit's requirements on wireless communication systems:
Secure and reliable
transmission of CBCT
information
CBTCPIS
Information release, onboard
streaming media, video ads,
and disaster emergency
release
Trunking Dispatching
Vehicle dispatching and
voice trunking
communication among
multiple work groups
Video Surveillance
Multiple channels of HD
videos in compartments
and the driver's cab
Wireless networks promote the transformation of mass transit production and operation modes and improve operation safety and efficiency.

Challenges on Traditional Wireless
Communication SystemsExisting train-to-ground wireless communication systems have many
problems. For example, surveillance videos cannot be backhauled,
PIS HD videos cannot be smoothly played, and network interference
keeps increasing. Traditional wireless systems cannot adapt to the
rapid development of mass transit services. Customers are in an
urgent need of a large-bandwidth, high-reliability train-to-ground
