The societal ambitions of zero fatalities and climate neutrality in road transportation, as well as future ambitions of automated driving require a new approach to the handling of road traffic information. The key stakeholders of the ecosystem, global automotive OEMs, service providers (SPs) and infrastructure owner-operators (IOOs), need new digital methods of operating and interworking.

This white paper proposes a transformative approach for automotive stakeholders, emphasizing scalable digital data exchange and a federated architecture to manage road traffic information efficiently. The architecture ensures bidirectional communication, delivering static, semi-static, and near real-time data for safe and efficient transportation. The paper concludes with recommendations for a National Roadway Digital Strategy, federated information-sharing structures, and aligned investments. Emphasising the integration of technologies and data-driven decision-making, it aligns with 5GAA’s mission to propel road traffic operations into the digital age.

Panel Discussion: Supporting the market growth of connected vehicles

Date & Time: Tuesday, 3 June 2025 | 14:40 – 15:25
Location: The Fairmont Windsor Park, Windsor, UK

As the connected and autonomous vehicle market accelerates, the global value of Vehicle-to-Everything (V2X) technology is expected to soar within the next decade. This evolution—culminating in the widespread deployment of 5G-V2X—marks a critical shift toward the software-defined vehicle (SDV), where advanced connectivity features are embedded from the ground up.

This panel brings together industry leaders to explore how the automotive ecosystem is preparing for this transformation and what is needed to support large-scale market growth. From evolving business models and cross-sector collaboration to overcoming deployment barriers, the discussion will also examine the crucial role that telecommunications providers must play to meet rising demands for seamless, reliable, and secure connectivity.

5GAA will be represented by CTO Maxime Flament, who will offer insights from the association’s work at the intersection of telecom, automotive, and infrastructure, and highlight key enablers for achieving truly connected mobility.

The 5G Automotive Association (5GAA) has released its 2024 Annual Report, highlighting the association’s continued progress toward the global deployment of Cellular Vehicle-to-Everything (C-V2X) technology and the realisation of connected mobility solutions. The report outlines 5GAA’s milestones and achievements over the past year across strategic areas such as policy engagement, standardisation, technical innovation, and global collaboration. 

Expanding Global Presence and Strengthening Industry Collaboration 

In 2024, 5GAA brought together over 110 member organisations from across the globe, reflecting a truly international footprint in advancing connected mobility. The membership spanned Europe (45%), Asia (31%), and the Americas (24%), and included 10 of the top 15 global automakers, 8 of the top 10 mobile network operators, and 2 leading smartphone manufacturers. 

Beyond its core membership, 5GAA also strengthened ties with more than 40 external organisations, with new cooperation agreements signed with the Chinese Institute of Communications and the Automotive Edge Computing Consortium.

• In a global premiere, 5GAA members demonstrated connected vehicles using non-terrestrial networks (NTN), complementing terrestrial 4G and 5G networks
• The event featured the first on-the-road, live-traffic demonstration of 5G-V2X Direct technology capabilities for advanced connected mobility services
• 5GAA members showcased ready-to-deploy vehicle-to-network (V2N) technologies improving road safety in real traffic conditions.

PARIS, 15 May 2025 — For the first time worldwide, the 5G Automotive Association (5GAA) showcased connected vehicles using non-terrestrial networks (NTN) for emergency messaging, as well as 5G-V2X Direct for advanced detection of vulnerable road users (VRU) in real-traffic conditions. 5GAA members also demonstrated the readily available capabilities of Vehicle-to-Network (V2N) services.

“Today, we saw real vehicles on real roads, connected through cutting-edge technologies such as satellite, 5G-V2X Direct and commercial networks. This is the future of automotive connectivity, and it’s closer than you think,” said 5GAA Chairman Christoph Voigt.

5GAA members, vehicle manufacturers BMW Group and Stellantis and technology partners Anritsu,Cubic³, Deutsche Telekom, HARMAN, Jember, LG Electronics, Qualcomm Technologies, MediaTek, Rohde & Schwarz, Rolling Wireless, Skylo, VEDECOM Institute and Viasat demonstrated NTN satellite connectivity. Demonstrations focused respectively on realising hazard warning and emergency messaging use cases in the vehicle, as well as illustrating how NTN will complement terrestrial 4G and 5G networks in the future. Demonstrations on public roads emphasised the vision of how NTN can support ubiquitous automotive connectivity for connected services with seamless integration and switching between NTN and terrestrial networks to enable voice communication. In the future, car drivers may not even realise that satellite connectivity is being established instead of using a terrestrial network. According to 5GAA 2030 Roadmap, the initial market deployment of satellite connectivity in vehicles is expected by 2027 (based on IoT NTN 3GPP Release 17).

Anritsu, Keysight Technologies, Rohde & Schwarz, and MediaTek complemented the NTN demonstrations with parallel test equipment measurements for performance verification.

For the first time on the road, 5GAA member Valeo, in collaboration with Marben, demonstrated 5G-V2X Direct, in which two vehicles shared sensor data, triggering a warning of a pedestrian crossing at an obstructed intersection. This demonstration illustrated how 5G-V2X Direct (based on 3GPP Release 16) will enable vulnerable road users’ advanced protection by leveraging sensors and camera feeds from other vehicles to alert drivers, paving the way for smarter mobility. As per the 5GAA Visionary 2030 Roadmap, 5G-V2X is expected to be mass-deployed in commercial vehicle models starting from the time horizon 2026-2029.

The public road demonstrations continued with V2N technology for road users’ protection. 5GAA members, including Nokia, Orange, Stellantis, Valeo, and VEDECOM Institute, showcased interoperable V2X Platforms with vehicles, mobile applications and smart intersections (equipped with cameras and connected via the 5G networks) sharing collective perception to enhance road users’ safety. Additionally, HARMAN and u-blox showcased Emergency Electronic Brake Light (EEBL) near-real-time alerts to prevent hard braking events, in line with the upcoming 2026 Euro NCAP local hazard requirements, and used precise positioning techniques to prevent false alerts.

5GAA members Rohde & Schwarz, S.E.A., Keysight and Orange alsoexhibited Next Generation Emergency Call (NG eCall) verification and network performance.

The event, hosted by Telecom-Paris, highlighted how 5GAA is developing new standards for safety and innovation in automotive connectivity in Europe and globally.

As part of its cooperation agreement with GSMA, 5GAA intends to work with the GSMA Post-Quantum Telco Networks (PQTN) Task Force to explore the impacts that quantum computing and the migration to post-quantum cryptography has on the connected automotive sector and its customers. Through this cooperation, 5GAA and the GSMA PQTN Task Force will gain insights to help both the telco and automotive industries strengthen the future of connected automotive security with post-quantum cryptography and crypto-agility. The rapid evolution of automotive E/E architecture and Software-Defined Vehicles has transformed modern vehicles into highly connected computing platforms, enabling advanced functionalities such as Vehicle-to-Everything (V2X) communication, autonomous driving, and over-the-air updates. This increasing connectivity significantly expands the attack surface for bad actors, making vehicles more exposed to cyber threats.
