Onboard Multi-Network Router

Onboard Multi-Network Router
Reliable Onboard Connectivity for Railway Communication Systems
The Onboard Multi-Network Router is a core communication device designed for
railway and transit onboard network systems. It provides stable and continuous
data connectivity by integrating multiple cellular networks, serving as the
central gateway between onboard equipment and ground communication
infrastructure.
ZTLX Onboard Multi-Network Routers are developed specifically for mobile
railway environments and are widely applied in high-speed rail, metro, light
rail, and intercity train systems. They form the backbone of onboard networks
supporting passenger Wi-Fi, train-to-ground communication, video services, and
operational data transmission.
Key Functions of an Onboard Multi-Network Router
As the central node of onboard communication architecture, an Onboard Multi-
Network Router is responsible for:
Aggregating multiple cellular network connections for onboard data transmission
Acting as the primary gateway between onboard systems and ground networks
Supporting continuous connectivity during train movement
Enabling unified management of onboard communication traffic
It is typically deployed together with onboard wireless access points (AP),
access controllers (AC), onboard Ethernet switches, and other onboard
communication devices.
