Public safety on the move: connectivity that stays under your control

An ambulance races towards an emergency in a rural area. Inside, paramedics monitor a patient's vital signs, communicate with dispatch, and prepare to share critical information with the hospital before arrival. Every second matters, but there is one challenge even the most advanced emergency vehicle cannot solve alone: unreliable connectivity.

According to Stellar's testing across Europe and North America, up to 40% of roads lack reliable network coverage. For emergency services increasingly dependent on real-time information, losing connectivity can mean losing access to critical data when it matters most.

The problem: Coverage gaps and data control

Ambulances, fire brigades, and police vehicles are becoming connected operational environments. From live video and patient monitoring to location tracking and dispatch updates, reliable internet is essential to coordinating emergency responses. Yet most vehicles still depend on a single telecom network, and no operator can guarantee coverage everywhere.

But staying connected is only half the challenge. European public safety agencies must also consider where their data travels, who manages their connectivity, and who governs the underlying infrastructure. With growing cybersecurity requirements and concerns around technological sovereignty, dependence on non-European technology providers introduces risks that go beyond network performance.

The challenge is clear: emergency services need connectivity that is both resilient and under their control.

The solution: Resilient and sovereign connectivity

What if emergency vehicles could use multiple networks instead of depending on just one? And what if the technology managing those connections remained entirely under European control?

This is where Stellar comes in. Stellar offers resilient connectivity across networks by orchestrating multiple communication technologies into a single, continuous internet connection. Rather than relying on one operator, its technology aggregates available terrestrial and satellite links, switching seamlessly between them as conditions change.

For an ambulance travelling through areas with inconsistent coverage, this means patient information and dispatch updates can continue flowing through alternative available networks. The vehicle is no longer restricted to one operator's coverage, reducing the risk of communication interruptions.

And because Stellar is a European technology company with a fully European technology stack, agencies can maintain sovereign control over their connectivity infrastructure without compromising performance.

The benefits: Connectivity that supports every mission

For public safety organisations, this approach delivers more than reliable internet. It strengthens operational readiness while addressing growing security and sovereignty requirements.

• Reach crews where single networks fail. Multiple available networks work together to extend reliable connectivity across rural roads, remote locations, and challenging environments.
• Keep control under European jurisdiction. European-developed technology and sovereign infrastructure reduce dependence on non-European orchestration providers, giving agencies greater control over connectivity and data flows.
• Integrate with existing hardware. Stellar's software can run directly on compatible vehicle routers and existing equipment, avoiding unnecessary hardware replacements.
• Protect sensitive communications. Encrypted connections and secure traffic management help safeguard operational information while maintaining application performance.

Powered by Stellar: STEER® security and sovereignty

Behind this solution is STEER®, Stellar's proprietary network orchestration software. It intelligently aggregates multiple connections at IP packet level, and switches seamlessly between available paths to maintain communication.

Unlike solutions requiring dedicated new equipment, STEER® can be integrated directly into an agency's existing compatible hardware. Its lightweight architecture makes it particularly suited to emergency vehicles, where reliability, efficiency, and straightforward deployment matter.

Stellar put together a kit with all necessary components for emergency vehicles. Combining the GLOBBLE® smart router, STEER® network orchestration software, and access to cellular and satellite connectivity, the kit keeps critical information flowing even as network conditions change. With a pre-configured setup and remote management capabilities, emergency services can strengthen their connectivity without adding unnecessary complexity to their operations.

This solution combines mission-critical resilience with European sovereignty, allowing agencies to maintain greater control over the systems supporting their operations.
