Their core work

Commsignia is a Hungarian SME specializing in vehicle-to-everything (V2X) communication technology for connected and automated driving. They develop hardware and software for roadside units and onboard vehicle communication systems, enabling cars to talk to infrastructure and each other using standards like ETSI ITS-G5. Their work spans the full stack from precise GNSS-based positioning (using Galileo signals and RTK corrections) to cybersecurity assurance for connected vehicle networks. In EU projects, they contribute V2X communication expertise to large-scale automated driving pilots and cross-border demonstrations.

What they specialise in

How they've shifted over time

Commsignia's early H2020 work (2017-2018) centered on cybersecurity and safety assurance for connected vehicle systems — building frameworks for threat analysis, risk calculation, and security certification of V2I communication. From 2019 onward, their focus shifted decisively toward connected automated driving itself, with emphasis on precise GNSS positioning (Galileo, RTK), sensor fusion, and participation in large-scale cross-border driving demonstrations. The trajectory shows a company that moved from securing the communication layer to actively enabling autonomous vehicle deployment.

Commsignia is moving from R&D-stage communication technology toward real-world piloting and large-scale deployment of automated driving, making them a strong partner for projects bridging the gap between lab and road.

How they like to work

Commsignia operates exclusively as a project participant, never as coordinator — typical for a focused technology SME that brings specialized components rather than managing large consortia. With 153 unique partners across 23 countries in just 5 projects, they consistently join very large consortia (averaging 30+ partners per project). This means they are experienced at integrating their V2X technology into complex multi-partner systems and are comfortable working across diverse European teams.

Commsignia has collaborated with 153 distinct partners across 23 countries through 5 projects, giving them an unusually broad European network for an SME of their size. Their partnerships span the full connected driving ecosystem — from automotive OEMs and road operators to research institutes and cybersecurity firms.

What sets them apart

Commsignia sits at the intersection of V2X communication hardware, GNSS-based positioning, and vehicular cybersecurity — a rare combination that covers the full trust chain from "where exactly is the car?" to "is this message authentic?" Few SMEs can offer both the communication stack and the security assurance layer for connected driving. Their participation in Hi-Drive (running until 2025) means they bring current, hands-on experience with large-scale automated driving pilots.

Highlights from their portfolio

• Hi-Drive
  Their most recent and longest-running project (2021-2025), focused on large-scale cross-border deployment of higher automation — signals their move from R&D to real-world piloting.
• SAFERtec
  Their highest-funded project (EUR 315,000), developing security assurance frameworks specifically for networked vehicle technology — foundational to their cybersecurity credentials.
• PRoPART
  Combines EGNSS precise positioning with V2X communication and sensor fusion — showcases their unique ability to integrate positioning and communication for automated driving.
