5GAA Tech Demos in Paris: 5GAA Brings First-Ever Satellite and 5G-V2X Direct Vehicle Connectivity to Life
In a global premiere in May 2025, the 5G Automotive Association (5GAA) demonstrated connected vehicles using non-terrestrial networks (NTN) complementing terrestrial 4G and 5G networks for emergency messaging. It also did the first on-the-road, live-traffic demonstration of 5G-V2X Direct technology capabilities for advanced connected-vehicle services and ready-to-deploy vehicle-to-network (V2N) technologies, which can improve road safety in real traffic conditions.
Missed the demos? No problem! Now you can see the replay of these advanced vehicle technologies! Watch the full video below to experience the demos in action!
5GAA-member 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 participated in the NTN satellite connectivity demonstrations. The demos focused 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 underlined 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 has replaced a terrestrial network. According to the 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 public roads, 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 warning requirements, and used precise positioning techniques to prevent false alerts.
5GAA members Rohde & Schwarz, S.E.A., Keysight and Orange also exhibited Next Generation Emergency Call (NG eCall) verification and network performance.
The event, hosted by Telecom-Paris, highlighted how 5GAA is driving the development of new standards for safety and innovation in automotive connectivity in Europe and globally.

Mobile Edge Computing Use Cases, Initial Test Specifications and Evaluation Methodology Review
This second Technical Report (TR) edition provides an updated set of Use Case requirements, and a new evaluation methodology review for deployment potential using Mobile Edge Computing (MEC) infra-structure. The work is based on Use Cases (UC) and requirements developed by 5G Automotive Association’s Work Group 1 (WG1) and other organisations, such as the European Telecommunications Standards Institute (ETSI) MEC and China’s IMT 2020 PG.
Down-selection and analysis of UCs are outlined in this TR according to different objectives and criteria, including the technology’s feasibility and demonstrated capabilities, its evaluated performance, its proven business potential, etc. For this, a vehicle Original Equipment Manufacturer (OEM) perspective on UCs is featured because the end application is consumed on the vehicle side. Additional requirements, such as end-to-end (E2E) security schemes, should also be considered.
The newly introduced evaluation methodology presented in this TR is examined through discussion of examples and best practices. The aim of this approach is to help OEM’s better evaluate how/when to deploy vehicle features on-board, in MEC, or in a central cloud. A discussion of the relevant criteria to be considered, and the related technical or business issues for these criteria, is given to guide the reader through the evaluation methodology.

Credential Management Supporting V2X Commercial Deployments
Currently, for V2X direct communication, there is no available common policy (certificate policy for Public Key Infrastructure, or PKI, operators) for Security Credential Management System (SCMS) in the U.S. or Canada. A few SCMS providers created their own policies, which are not only incomplete but there are no published common policy documents feasible for SCMS PKI operation, hindering the widespread adoption of the technology. The Government of Canada sponsored an effort which resulted in a model for consideration.
A common Certificate Policy (CP) would help facilitate an ecosystem supporting interoperability and shared trust for V2X direct communication. The European Union addresses this issue by taking a central regulatory role, creating the CP, Security Policy (SP) and C-ITS Point of Contact (CPOC) documents that govern a V2X PKI for direct communication. North America need not duplicate what has been done elsewhere, though an accepted policy will build a greater ecosystem and support V2X direct deployment among a diverse set of automakers and other transport agencies.
The Certificate Policy Proposal contributing to this Work Item (WI) evolved into a Technical Report (TR) that develops a clear CP leveraging global best practices for security PKI and practical experience securing V2X direct communication, as well as common processes to facilitate an approach to SCMS.
For V2X mobile network communication, certificates are needed to authenticate interconnected backend systems and to protect communication between the systems. This Technical Report also elaborates on how to handle those certificates.

V2N2X security, privacy, and data quality
Cellular Vehicle-to-Everything, or C-V2X, is an umbrella term that encompasses all 3GPP V2X technologies, including both direct (PC5) and mobile network communications (Uu). In many cases, both direct and network modes of C-V2X can be used for the same or similar automotive and Intelligent Transport System (ITS) applications, yet with different service characteristics. However, there are fundamental differences when it comes to the architecture and realisation of different Use Cases applying mobile network vs. direct, short-range, communications. This leads to different ways of handling security, privacy, and how to ensure data quality – the fundamental requirements of every ITS service – when using C-V2X mobile network communication or direct communication. This is already reflected in other organisations such as ITS America.
This 5GAA paper provides an overview of how security, privacy, and data quality are addressed for C-V2X using mobile network and backend communications, also known as Vehicle-to-Network-to-Everything (V2N2X) solutions.
The paper was originally published in December 2024. The current downloadable version is the updated edition, released on 3 June 2025. 5GAA remains committed to keeping all its publications accurate and up to date.
