Medha’s Network and Communication systems are engineered to meet the evolving demands of modern railway operations, ensuring seamless integration, high reliability, and robust performance.
Train-to-Ground Communication and Internet Access
Our Wireless Data Link (WDL) serves as the onboard communication hub, facilitating data and multimedia exchanges between the train and ground operations centres (OCC). Leveraging Wi-Fi and cellular networks (3G/4G), the WDL enables:
- Passenger Internet Access (PIA): Provides onboard Wi-Fi, enhancing passenger experience by offering internet connectivity throughout the journey.
- Operational Communication: Ensures real-time data transmission for diagnostics, monitoring, and control, supporting efficient train operations.
Key features include dedicated cellular and Wi-Fi links, secure interfaces with the train’s Ethernet network, and integration with onboard diagnostic systems. The system is designed with advanced security protocols, configurable functional parameters, and firewall capabilities to safeguard data integrity.
Onboard Networks
To support the increasing complexity of onboard systems, Medha offers robust networking solutions capable of managing high-bandwidth multimedia and data communications. Our networks are designed to handle the dynamic nature of train compositions, ensuring reliable performance even when train configurations change.
Key features include redundancy management via Virtual Router Redundancy Protocol (VRRP), fast Ethernet ports with or without Power over Ethernet (PoE) for end devices, and gigabit ports for ring connections and mobile gateway interconnections. Our systems support various network nodes, such as:
- ECS1: Basic Ethernet Consist Network (ECN) node.
- ETBN: Mixed ECN and Ethernet Train Backbone (ETB) node, functioning as a router according to ETB operations.
- ECS2: Mixed ECN and ETB node with advanced capabilities.
These components ensure efficient data traffic management, prevent IP conflicts, and maintain seamless communication across the train’s network.
Medha’s commitment to innovation and quality ensures that our Network and Communication systems provide reliable, secure, and efficient solutions for modern railway operations, enhancing both passenger experience and operational effectiveness.
