Rail transportation is evolving at a rapid pace, driven by the need for smarter, safer, and more resilient communications that can support everything from real-time monitoring to advanced control systems. In this context, NEXCOM International Co., Ltd. and Hytec Inter Co., Ltd. have announced a strategic partnership to deliver a unified 5G satellite communications solution tailored for mission-critical rail operations.
Announced at MWC Barcelona 2026, this collaboration aims to eliminate connectivity gaps across tunnels, remote routes, and mixed network environments by integrating public and private 5G networks into a seamless hybrid architecture. The combined solution supports high-mobility scenarios where continuous, low-latency communication is essential for safety, operations, and future-ready rail systems.
The Rail Connectivity Challenge
Traditional rail communication systems often rely on segmented network architectures, which can lead to intermittent coverage and handover failures, especially in tunnels or rural areas. This is increasingly problematic as rail operators adopt advanced systems like Communications-Based Train Control (CBTC) and prepare for the transition to the Future Railway Mobile Communication System (FRMCS). FRMCS is an emerging global standard designed to replace legacy technologies with 5G-based mission-critical services that offer higher data capacity, ultra-low latency, and enhanced reliability. In this landscape, deterministic connectivity, defined as predictable, always-on network performance, is becoming a foundational requirement for rail safety and operational efficiency.
A Unified Hybrid 5G Approach:
The NEXCOM-Hytec Inter partnership brings together NEXCOM’s ISA-141 dual 5G onboard unit and Hytec Inter’s private 5G infrastructure, creating a unified hybrid system capable of seamless handovers between network types via Dual SIM Dual Active (DSDA) technology. The hybrid architecture ensures that communication remains uninterrupted even during transitions between public and private networks, a common pain point for mission-critical operations. This integration supports safety systems, real-time monitoring, fleet management, and operational communications on metro, regional, intercity, and high-speed rail lines.
Executive Perspectives: Reliability Meets Mission Focus:
Allan Chiu, Vice President of Network & Communication Solutions at NEXCOM, emphasizes that modern rail communications must go beyond traditional coverage models. According to Chiu, the industry is shifting toward deterministic, always-on connectivity that allows mission-critical systems to function without interruption. He notes that dual 5G onboard connectivity provides a scalable foundation for today’s rail demands as well as future FRMCS-centric advancements.
Asao Norihito, President & CEO of Hytec Inter, highlights the importance of eliminating connectivity gaps in rail infrastructure. Norihito underscores that every network transition is a potential point of operational failure, especially in safety-critical contexts. The joint solution is engineered to mitigate these risks by creating a unified 5G network that delivers uninterrupted performance and predictable behavior, enhancing both reliability and system robustness.
Impacts on Rail Operations:
The hybrid 5G system developed by NEXCOM and Hytec Inter is designed to support the rail industry’s push toward digital transformation and intelligent operations. Key anticipated benefits include:
Continuous Network Coverage: Reduced service interruptions in challenging environments, including tunnels and remote regions.
Enhanced Safety Systems: Reliable support for mission-critical control systems and real-time alerts.
Operational Efficiency: Stronger communication channels for monitoring, diagnostics, and scheduling.
Future-Proof Architecture: A scalable platform that aligns with upcoming FRMCS standards and advanced digital rail services.
Conclusion: Building Resilient Rail Networks
The NEXCOM and Hytec Inter partnership illustrates how hybrid 5G communications can solve long-standing challenges in rail connectivity. By blending public and private 5G capabilities into a unified mission-critical platform, the collaboration sets a new benchmark for reliable rail communications, which is one that prepares operators for the next era of digital rail services. As rail networks evolve and adopt more complex control systems, solutions like this will be critical for delivering the continuous performance rail operator’s demand.
