The rail industry is navigating one of its biggest shifts in decades. We are seeing the technology switch from GSM-R to FRMCS. Build on 5G NR and private LTE becomes an immediate operational imperative. However, this creates a fundamental paradox for rail operators: rolling stock is built for a 20-to-30-year service life, yet the embedded computing and connectivity technology driving modern operations often face obsolescence in under five years. 

To bridge this gap, Train-to-Ground (T2G) edge gateways must satisfy critical hardware requirements: 

• High Operational Reliability: Uninterrupted operation demands fanless designs using industrial-grade components to achieve an MTBF exceeding 250,000 hours.  

• Power & Mechanical Robustness: Integrated wide-range DC input (24V–110V) handles rail power fluctuations directly, alongside lockable M12 connectors complying with EN 61373 shock and vibration standards.  

• Cross-Border Seamless Connectivity: Multi-carrier, dual-modem architectures with multi-SIM capability maintain continuous high-bandwidth video and telemetry links across national borders.  

• Non-Negotiable Cybersecurity: Compliance with the IEC 62443-4-1 secure development lifecycle, backed by TPM 2.0 hardware security to meet emerging regulatory standards like the EU Cyber Resilience Act. 

One Gateway, Built to Last 

ADLINKの ADLINK AVA-1000 is a scalable T2G platform engineered to solve the lifecycle gap, lower total cost of ownership, and evolve alongside future onboard applications.  

Modular Architecture & Long Lifecycle Support 

Powered by ADLINK’s SMARC modules, operators can seamlessly scale from power-efficient Arm processing to high-performance Intel x86 computing without replacing the gateway. This protects initial investments, reduces redesign effort, and simplifies fleet maintenance and spare-parts management.  

Uninterrupted Multi-Carrier Connectivity 

Equipped with dual 5G modems and multi-SIM support (with RED-certified 5G on x86 models), the platform maintains continuous, high-bandwidth links across operators and national borders. Service-accessible SIM slots further simplify carrier changes and reduce maintenance downtime.  

Railway-Grade Reliability 

Featuring an integrated 24–110V DC power input and M12 connectors, the AVA-1000 eliminates extra cabling and external failure points. Its fanless design, wide operating temperature range (-40°C to +70°C), and validated MTBF exceeding 250,000 hours deliver long-term dependability, compliant to EN 50155, EN 50121, EN 45545-2, and IEC 61373 standards.  

Cybersecurity-Ready 

Developed under ADLINK’s IEC 62443-4-1-certified Secure Product Development Lifecycle, the AVA-1000 minimizes integration risks and supports secure end-to-end lifecycle management.  

As railway operations evolve toward a 5G-connected future, the gateway architecture you deploy today will determine your network’s adaptability for the next two decades.
