- Real-time vehicle communication highlights the potential for enhanced road safety by detecting vulnerable road users and avoiding accidents.
- The first satellite-connected cars are expected to debut around 2027, integrating advanced technologies aimed at improving connectivity and safety on the roads.
Innovations in Connected Car Technology
The 5GAA showcased breakthrough connected vehicle technologies using non-terrestrial networks (NTN) and Vehicle-to-Everything (V2X) applications aimed at improving safety in emergencies. NTN enables vehicles to send critical messages, particularly in locations far from mobile towers, ensuring timely communication during incidents.
During comprehensive demonstrations in real-world traffic settings, the 5G-V2X Direct technology was highlighted for its ability to empower vehicles in detecting vulnerable road users (VRUs), such as pedestrians and cyclists, even before they come into view. Christoph Voigt, Chairman of 5GAA, emphasizes the reality of automotive connectivity, stating, “This is the future… and it’s closer than you think.”
Notably, the demonstration involved major automotive players including BMW and Stellantis as well as tech companies like Qualcomm and Deutsche Telekom. The aim was to illustrate the feasibility of using satellite technology for emergency warnings, which can complement existing 4G and 5G networks and fill coverage gaps. A significant feature showcased was connected cars’ ability to seamlessly switch between satellite and traditional mobile connections, ensuring continuous service during voice calls or SOS dispatches.
According to Kevin Cohen from Viasat, the implications are profound: satellite connectivity could enable emergency calls in areas lacking cellular service, automate alerts after collisions, and even allow businesses to track fleets in real-time. The vision set out by 5GAA suggests that satellite-connected vehicles will start appearing around 2027, underpinned by the IoT NTN 3GPP Release 17 standard.
Testing and validation were critical components of the demonstrations, with organizations like Anritsu and Rohde & Schwarz providing vital performance measurements. Adnan Khan of Anritsu noted that accurate field measurements are essential in validating NTN performance, enhancing stakeholder insights, and advancing innovation.
Another noteworthy demonstration involved Valeo and Marben, showcasing how two vehicles can share sensor data for increased safety. One vehicle warned another about a pedestrian looming at a blind corner, illustrating the potential for 5G-V2X Direct technology to grant cars an enhanced perception of their environment. The 5GAA anticipates this type of technology to be available in mass-market vehicles between 2026 and 2029.
Additionally, the demonstrations included Vehicle-to-Network (V2N) technology, showing how connected cars interact with broader networks. This interoperability allows different platforms—cars, mobile apps, and smart infrastructure like traffic lights—to collaboratively build a richer vision of real-time road conditions, ultimately enhancing safety.
HARMAN and u-blox introduced Emergency Electronic Brake Light (EEBL) alerts, designed to provide rapid warnings to prevent sudden brakes. This technology is relevant for upcoming Euro NCAP requirements, emphasizing accurate positioning to minimize false alerts.
The 5GAA and its partners are committed not only to discussing future technologies but are actively developing new standards aimed at making journeys safer and enhancing vehicle intelligence globally.
