The Real Challenge in Connected Mobility? Staying Connected.
Solving Automotive Connectivity Challenges with rSIM
By 2030, the global connected vehicle market is expected to exceed $215 billion, driven by autonomous vehicles (AVs), advanced driver-assistance systems (ADAS), smart EV infrastructure and the broader shift toward Mobility-as-a-Service (MaaS). Whether it’s an electric delivery van, a long-haul HGV, or a smart city shuttle, vehicles are becoming data centres on wheels that are dependent on fast, secure, and resilient connectivity.
But what happens when that connection drops?
The Rise of the Connected, Autonomous Vehicles
As vehicles grow smarter, the demands on their connectivity grow too. From predictive diagnostics to over-the-air software updates and real-time telematics, the need for always-on data flow is reshaping vehicle architecture. In many modern cars, connectivity now supports:
- Safety systems like eCall, ADAS and SOS alerts
- Navigation and infotainment, powered by real-time cloud data
- Fleet visibility, ranging from location tracking to vehicle health
- Remote updates to firmware and software for both critical and non-critical functions
This trend is also driving design changes: manufacturers are reducing physical wiring and relying more on wireless, over-the-air functions. Further increasing the reliance on uninterrupted connectivity.
The Connectivity Problem No One’s Talking About
While next-gen vehicle systems rely on lightning-fast data, our networks still struggle with patchy coverage, latency, and resilience. AVs and connected vehicles depend on real-time data exchange for navigation, diagnostics, fleet management, ADAS features, and remote OTA updates. But even brief losses in signal can have cascading effects.
Research shows that two of the main causes of faults in autonomous vehicle (AV) trials are directly linked to connectivity failures. These include poor adaptation to external environments and missed alerts due to real-time transmission loss . And it’s not just the cars themselves at risk, supporting infrastructure like RSUs (Roadside Units), data centres, and V2X systems are only as strong as their network reliability.
Even in major cities, mobile coverage along key road links can be inconsistent, with AVs experiencing degraded performance in dense urban environments due to sub-par telecom infrastructure . High latency, blind spots, and service blackouts are not just frustrating, but a direct threat to safety and progress.
Put simply, the more connected our vehicles become, the more we rely on resilient, fail-safe connectivity. Yet the industry is still catching up.
Driving Forward: Resilient Connectivity for Connected Vehicles
Autonomous and connected mobility are complex ecosystems, pulling data from the cloud, other vehicles (V2V), infrastructure (V2I), and mobile networks. But all of this collapses if a single point of connectivity fails.
The next generation of telematics must account for this. And that means building in resilience at the very edge of the system, not just at the core.
Resilience is where rSIM is designed to close the gap. With dual-core architecture and built-in intelligence, rSIM delivers autonomous failover between two operator profiles, right inside the SIM itself. No manual resets, no firmware dependencies, no waiting on remote servers.
In the context of connected vehicles, that means:
- Continuous communication, even during mobile network failures
- Real-time diagnostics, OTA updates and navigation remain uninterrupted
- eCall and safety alerts get through, every time
- Fleet operations don’t grind to a halt due to connectivity loss
And it’s not theory. rSIM is already powering critical infrastructure, including emergency alert systems like BHV-Knop, where missed signals could mean missed resuscitations. Their real-world results? Failover now happens in under two minutes down from eight hours previously
The Future of Vehicle Connectivity: Built-In Resilience
As connected mobility, AVs, EVs and fleets continue to evolve, the cost of lost connectivity is rising. Not just in operational delays, but in safety risks, customer dissatisfaction and missed opportunities for smarter vehicle performance.
The industry is investing billions in AI and advanced telematics, but these systems can’t function without a strong, always-available connection. rSIM brings that resilience to the edge. Where the vehicle operates, decisions are made, and safety is critical.
