Unified hybrid 5G rail communications solution debuts at MWC26

NEXCOM and Hytec Inter unveiled a unified hybrid 5G rail communications solution at MWC26, positioning it as a platform for mission-critical rail operations, as reported by Developing Telecoms. NEXCOM is a provider of mission-critical network platforms, while Hytec Inter is described as Japan’s 5G wireless communication expert.

The companies say the rail communications solution is aimed at environments that need continuous connectivity across tunnels, remote areas, and mixed public–private network coverage. The stated goal is to avoid service interruption under high mobility.

MWC26 announcement and MoU for global 5G innovation

During MWC26, the two companies also signed a memorandum of understanding (MoU), calling it a milestone in their shared commitment to advancing global 5G innovation, according to PR Newswire. Also, the MoU and the product announcement were framed as part of the same collaboration around a scalable 5G architecture for rail.

Dual 5G onboard connectivity and DSDA seamless handover

At the technical core, the collaboration combines NEXCOM’s ISA 141 dual 5G onboard user equipment with Hytec Inter’s private 5G solution. The companies say dual SIM dual active (DSDA) operation enables seamless handover between networks. In addition, they describe this as a way for services to remain connected as coverage shifts between public and private domains, as Hytec Inter notes in its MWC Barcelona 2026 update.

The approach is intended to support safety-critical control, real-time monitoring, and operational communications within a single physical network. At the same time, it is presented as part of the broader push toward deterministic, always-on connectivity for rail operations.

CBTC demands and the FRMCS transition shaping rail communications

The companies framed the launch against growing pressure on rail operators and system integrators to support communications-based train control (CBTC) systems. Separately, they point to the industry’s transition toward the Future Railway Mobile Communication System (FRMCS), arguing that legacy rail communication architectures are difficult to scale and maintain as requirements evolve.

NEXCOM and Hytec Inter say the solution is designed for deployment across metro, regional, intercity, and high-speed rail networks and is positioned as a scalable platform for intelligent rail operations and critical infrastructure communications.

Allan Chiu, VP of Network & Communication Solutions at NEXCOM, explains: “Rail communications are moving beyond coverage alone towards deterministic, always-on connectivity. By deploying dual 5G onboard connectivity, this solution provides a practical foundation for mission-critical rail systems today and for future FRMCS evolution.”

Asao Norihito, President & CEO at Hytec Inter, adds: “In critical rail infrastructure, every network transition represents a potential point of failure. Our joint solution is built to eliminate those gaps by enabling mission-critical services to operate on a unified 5G infrastructure engineered for uninterrupted performance and predictable behaviour.”
