GSM‑R - FRMCS: Support Kontron Transportation

As rail networks evolve towards digital, mission‑critical communications, system integrators need partners who can support both today’s GSM‑R deployments and the long‑term transition to FRMCS. HUBER+SUHNER works across the rail ecosystem to provide reliable RF and fiber‑optic infrastructure that underpins these networks from trackside to core.

One such partner is Kontron Transportation, a global provider of railway radio communication solutions for high‑speed rail. Over multiple projects, HUBER+SUHNER has supported Kontron Transportation with a scalable, future‑ready approach that combines product availability, system expertise and migration readiness.

High‑speed rail GSM‑R projects are complex, long‑running and geographically distributed. To deliver them successfully, Kontron Transportation requires:

A single, dependable supplier capable of delivering complete trackside RF, FO and LF solutions
Long‑term product availability and consistency, critical for multi‑year rollouts
Antenna and infrastructure solutions that ensure robust GSM‑R performance today
A clear path towards FRMCS migration, avoiding stranded assets during the coexistence phase

Managing multiple suppliers across antennas, RF components, fiber optics and accessories would introduce unnecessary risk, complexity and integration effort.

GSM-R trackside infrastructure: Our support spans a comprehensive range of trackside infrastructure for GSM‑R mainline applications, combining high‑gain MIMO antenna solutions for 900 MHz GSM‑R with options that already support 1900 MHz FRMCS. This is complemented by RF cables and assemblies, fiber‑optic jumpers, lightning protection and passive RF components, together with mounting hardware and field‑mountable connectors that simplify on‑site installation.

In addition, we deliver project‑specific kitting and logistics, ensuring each mast and site receives exactly the right configuration. This integrated approach reduces supply‑chain friction, simplifies project management and allows Kontron Transportation to focus on system integration and customer delivery.

Built-in readiness for FRMCS: While GSM‑R remains in the rollout phase across several regions, the transition to FRMCS is already underway. HUBER+SUHNER actively supports Kontron Transportation in preparing for this shift by enabling a smooth coexistence and migration strategy. Trackside antenna solutions are available that support both GSM‑R (900 MHz) and FRMCS (1900 MHz), allowing both technologies to operate on the same infrastructure. Consistent product designs with identical geometry and wind‑load profiles make it possible to upgrade networks without mechanical re‑work, even on constrained masts.

This approach is further supported by the expansion of the SENCITY® SC Panel antenna portfolio, ranging from GSM‑R‑only variants for legacy deployments to dual‑band solutions for the transition phase and dedicated FRMCS antennas for upcoming 5G‑based railway networks. As a result, operators can deploy GSM‑R with confidence today, knowing their infrastructure is already aligned with FRMCS requirements.

By partnering with HUBER+SUHNER, Kontron Transportation benefits from a simplified sourcing model built around a single, trusted supplier, combined with predictable delivery and long‑term product continuity for GSM‑R projects. Consistent antenna form factors help reduce installation effort and risk, while a clearly defined, future‑proof migration path ensures a smooth transition to FRMCS. Together, Kontron Transportation and HUBER+SUHNER are enabling secure, high‑performance railway communications – supporting GSM‑R networks today while laying the groundwork for the next generation of FRMCS‑based rail connectivity.

“In cooperation with Kontron Transportation, a deep understanding of trackside railway signaling and radio infrastructure is essential. At the same time, we actively contribute to shaping the onboard GSM‑R and FRMCS roadmap through our product portfolio, ensuring reliable GSM‑R operation today and a well‑prepared transition towards FRMCS.” Tobias Jahn, Key Account Manager Railway, HUBER+SUHNER."
