Railway Use Cases

RLW-UC01 — Joint Terrestrial and Satellite On-Board Connectivity

Goal

High Level Description

Seamless, uninterrupted, high-quality communication for trains by dynamically switching between or simultaneously using TN and NTN networks. This ensures that train operations and services function without disruption, regardless of location, speed, or constraints such as tunnels, rural areas, or degraded modes. The hybrid network serves critical, performance, and business communications, ensuring a resilient, multi-connectivity network for reliable train operations.

A key focus is providing uninterrupted connectivity for all railway services, including mission-critical operations, performance applications, and business communications, ensuring ultra-reliable, low-latency connectivity even in high-speed or remote/rural areas.

RLW-UC02 — Optimized Mobility Management and Resource Orchestration for High-speed Trains

Goal

High Level Description

Using 6G TN/NTN intelligent mobility management to dynamically optimize network resources, ensuring seamless connectivity for high-speed trains. The system leverages predictive analytics and real-time orchestration to anticipate demand variations and pre-allocate resources accordingly, reducing network congestion and improving service quality.

RLW-UC03 — Ubiquitous IoT Integration for Railway Monitoring

Goal

High Level Description

Leveraging 6G TN/NTN-enabled IoT to deploy long-life, energy-efficient sensors for real-time railway infrastructure monitoring. By integrating advanced power-saving mechanisms and energy harvesting solutions, IoT devices can operate autonomously for years while ensuring seamless TN/NTN connectivity

RLW-UC04 — Joint Connectivity for User Access to On-board Entertainment

Goal

High Level Description

Passenger receives content available on the train (e.g. video/movies) from multiple sources (multilink/multi carrier aggregation) with WiFi and LiFi, via enhanced future passenger-owned devices. LiFi provides a high-speed channel when unobstructed, while WiFi serves as alternative or complementary link. The system dynamically switches between or aggregates multiple links (e.g., using multipath TCP) to optimize content delivery.
