Whether railway operators or vehicle/system manufacturers. We efficiently integrate operational-relevant communication systems into your vehicle – transparently, in accordance with regulations, and with a clear focus on timely commissioning.
Train radio (Language communication) – Integration, tests and proof
Radio data transmission – Connectivity, routers/modems, interfaces and cybersecurity aspects
Retrofit – Migration of existing fleets/variants with minimal downtime
Engineering, documentation, verification/validation and commissioning from a single source
Experience from many European projects (rollout, retrofits, multi-country approvals, operator take-over)
Technically clean solutions, documented in a comprehensible manner and auditable
We integrate Train radio systems (e.g. MESA®26) into existing vehicle architectures, taking into account the installation location and the power supply. This also includes the connection of control and audio devices. One of our strengths lies in considering migration towards FRMCS, To enable an economical and sustainable solution. We offer you flexible migration solutions to protect your existing investment.
During the integration, all interfaces between manufacturers and operators are diagnosed and coordinated, and we provide installation and testing concepts including installation and acceptance documentation.
Of course, we provide support for type and batch testing, EMC assessments and evidence management.
We secure the connectivity for your operation, the diagnostic system, and the passenger and back-office applications. In the design and configuration process, we take into account routers/modems, antennas, data and service interfaces, and network coverage. We integrate the data link into your vehicle networks via Ethernet, IP services, and/or VPN, conducting performance and stability tests as needed. If required, we take care of your cybersecurity aspects (e.g., segmentation, hardening, and update/release management). Our operational and maintenance concepts regarding remote access, logging, and diagnostics ensure the operational safety of your data link.
We ensure a planned, sustainable and reproducible migration and fleet conversion with minimal downtime:
Conversion/migration concept including variant and change management
Retrofit kits: item lists, installation instructions, testing and acceptance procedures
Support for workshop/on-site installation, commissioning and error analysis
Rollout support from the pilot to the series, including lessons learned and process stabilization
In the railway market, the use of products without the necessary compliance with applicable regulations, including the corresponding certificates and approvals, is not permitted. Despite all efforts in the sector to harmonize and optimize requirements and procedures, the requirements remain high and the processes complex.
At this point, make the Funkwerk Licensing Management The difference: Our competent team of specialists works in close coordination with our customers, the assessment and approval authorities, and testing and inspection institutes around the topic of homologation.
Funkwerk provides support for the multifaceted requirements of the market for the ZZS component system testing of vehicles or series, or performs this testing on behalf of customers as well. In addition, we support the change management departments of operators, owners, or manufacturers in handling changes.
We also offer our services on current topics such as vehicle approval in the 4th Railway Package, Requirements Capture, Change Evaluation, Conformity Evaluation and Auditing.
