Finnish railway communications specialist bridging 5G FRMCS standards and GSM-R replacement for next-generation European train networks.
Teleste OYJ is a Finnish publicly listed technology company that designs and manufactures railway communications systems and broadband network infrastructure. In the H2020 programme, their work centred entirely on railway telecommunications — specifically the industry-wide migration from the legacy GSM-R radio standard to the 5G-based FRMCS (Future Railway Mobile Communication System). They bring working knowledge of train-to-ground radio links, spectrum planning, and interoperability testing against European rail standards such as ETCS and CCS TSI. Their role in research consortia is as a technology vendor and system integrator who can translate protocol specifications into testable hardware and software implementations.
5GRAIL (2020–2023) placed Teleste inside a large Shift2Rail Innovation Action focused on deploying 5G as the future railway radio bearer, with keywords covering FRMCS, GSM-R, 3GPP, ETSI, and spectrum management.
5GRAIL keywords include ETCS, ATO, TOBA, and TCMS, indicating Teleste contributed to the communication layer that underpins automatic train operation and European train control signalling.
GoF4R (2016–2018) addressed governance of the interoperability framework for rail and intermodal mobility under a Shift2Rail Coordination and Support Action.
5GRAIL keywords include 'spectrum' and 'test', suggesting Teleste's role involved spectrum allocation analysis and conformance or interoperability testing of 5G radio equipment against railway standards.
In their first H2020 project (GoF4R, 2016–2018), Teleste engaged at the policy and governance layer — contributing to how interoperability frameworks for rail should be structured — with no technical keywords attached. By 2020–2023 (5GRAIL), the focus had shifted entirely to deep technical implementation: 5G radio architecture, FRMCS protocol stacks, spectrum planning, and integration with train control systems. This is a clear arc from regulatory and framework participation toward proprietary, testable technology that sits inside the train and on the trackside.
Teleste is moving deeper into 5G radio for railways — future collaborations are most likely to involve FRMCS field trials, spectrum coexistence studies, or integration of 5G with train control and automation systems.
Teleste has participated in both projects as a consortium member, never as coordinator, consistent with a technology vendor that contributes specific product or testing capabilities rather than leading research agendas. Both projects were Shift2Rail initiatives with large multi-partner consortia — the 43 unique partners across just 2 projects confirms they operate in dense, industry-wide collaborations rather than small bilateral teams. This suggests they are comfortable as specialist contributors within a defined work package rather than taking on project management responsibilities.
Teleste has built connections with 43 distinct consortium partners across 15 countries through only 2 projects, reflecting the large pan-European consortia typical of Shift2Rail. Their network spans railway operators, telecoms vendors, universities, and standards bodies across the EU rail ecosystem.
Teleste sits at the rare intersection of commercial railway communications hardware and EU-funded standards research — they are not a pure research institute but a product company whose engineers participate in shaping the very standards their products must comply with. This gives them early visibility into FRMCS specifications before they are finalised, which is valuable to any consortium needing a vendor who can both test against draft standards and supply production-grade equipment. For a consortium builder, they fill the role of an industrial partner with genuine railway radio expertise rather than a systems integrator brought in for name value.
