The mobility of tomorrow will not be defined by vehicles alone, but by the networks that connect them. For predictive safety systems, connected vehicles, and smart highways to function seamlessly, communications must be fast, reliable, and borderless. This is exactly what the SafeRoute 6G project, part of the Celtic-Next cluster programme and funded through the Eureka framework, sets out to achieve.
In the UK, SafeRoute 6G is supported by UK Research and Innovation (UKRI), which acts as the national representative to Eureka. Together, these organisations ensure that SafeRoute 6G is not only advancing European innovation but also delivering value locally through national research and development priorities.
At the heart of the initiative lies a challenge: ensuring predictable, uninterrupted connectivity across multiple networks, jurisdictions, and use cases. That’s where Livewire’s Razorlink® SD-WAN solution comes in—delivering multi-network orchestration that keeps critical data flowing, even in the most demanding mobility environments.
What is SafeRoute 6G?
SafeRoute 6G is a pan-European collaboration focused on making road travel safer, smarter, and more efficient by leveraging next-generation 6G connectivity. The project is funded by Celtic-Next, part of the Eureka cluster programmes, with UKRI providing local support and representation in the UK.
Its objectives include:
-
Cross-border connectivity – ensuring vehicles remain connected when crossing national boundaries and switching between mobile network operators.
-
Predictive safety – enabling real-time data exchange so vehicles and infrastructure can anticipate and respond to risks before they occur.
-
Resilient communications – guaranteeing continuity of service for critical functions like vehicle-to-everything (V2X) alerts, traffic management, and emergency response.
-
Future-ready architecture – preparing Europe’s transport corridors for the demands of 6G and beyond.
In short, SafeRoute 6G provides a testbed for the next generation of mobility services, supported by Celtic-Next and Eureka to ensure global collaboration and alignment with national innovation strategies.
The Connectivity Challenge in Smart Mobility
As explored in our article Cross-Border Connectivity: The Final Frontier in Smart Mobility, one of the most pressing challenges for connected transport is the lack of seamless communications across borders.
Today’s vehicles often depend on a single mobile operator. This works well in urban areas, but once cars and freight vehicles cross into new regions—or worse, new countries—coverage may drop, service may degrade, and latency may increase. For everyday streaming apps, that’s an annoyance. For autonomous or safety-critical vehicles, it’s a potential catastrophe.
SafeRoute 6G addresses this head-on by proving that cross-border connectivity can be orchestrated across multiple networks at once. Instead of switching providers and risking data loss, vehicles can maintain session continuity, no matter where they travel.
Predictive Safety: Why Milliseconds Matter
Smart highways are not just about faster journeys—they are about safer ones. In Enabling Predictive Safety and IoT-Driven Traffic Management, we explained how intelligent infrastructure, IoT sensors, and AI models can anticipate danger before it happens.
For predictive safety to work, the flow of data must be continuous and virtually instantaneous. Consider:
-
A car encounters black ice and needs to alert following vehicles within milliseconds.
-
An autonomous truck must reroute to avoid a sudden traffic build-up.
-
Emergency services require real-time updates on vehicle positions and conditions.
-
Smart junctions need to dynamically adjust signals to prevent collisions when multiple vehicles approach at once.
Without low-latency, high-reliability communications, these scenarios break down. SafeRoute 6G’s innovation lies in ensuring that predictive safety applications are always connected, even across jurisdictions and network providers.
Why Smart Highways Need More Than 5G
While 5G promised to unlock connected transport, real-world deployment has shown limitations. Coverage is patchy, network capacity fluctuates, and no single operator can deliver ubiquitous service across Europe’s diverse landscapes.
As we argued in Why Smart Highways Need More Than 5G: The Case for Multi-Network SD-WAN, a single-network strategy is insufficient for safety-critical mobility applications. Vehicles need access to multiple networks simultaneously—and the intelligence to prioritise the right connection for the right application.
This is where Razorlink® SD-WAN is transformative.
Razorlink® SD-WAN: Powering SafeRoute 6G
Razorlink was built to solve the problems that standard mobile and broadband connections cannot. At its core, Razorlink is a Software-Defined Wide Area Network (SD-WAN) solution designed for multi-network environments—making it ideally suited for the SafeRoute 6G project.
Key benefits for smart mobility include:
-
Seamless Failover: If one network drops, Razorlink automatically switches traffic to another with no interruption to the user experience.
-
Bandwidth Aggregation: By combining multiple networks, Razorlink delivers the capacity required for demanding applications such as high-definition video feeds or aggregated sensor data.
-
Traffic Prioritisation: Safety-critical communications (e.g., collision warnings) are given top priority, while non-urgent data is shaped accordingly.
-
End-to-End Optimisation: Razorlink actively reduces packet loss, jitter, and latency—vital for predictive safety applications where every millisecond counts.
-
Cross-Border Continuity: Razorlink maintains active sessions when vehicles move across operator networks and country borders, ensuring uninterrupted service.
Imagine an ambulance convoy travelling from France into Germany. Without Razorlink, each vehicle might experience a communications drop as the operator network shifts. With Razorlink, the convoy remains connected across multiple networks, maintaining real-time updates and coordination with hospitals and traffic systems.
