What's Happening?
Viasat, in collaboration with Cubic³, Qualcomm Technologies, and Fraunhofer IIS, is set to demonstrate satellite-enabled voice calls over a 3GPP-compliant non-terrestrial satellite network for connected vehicles at the Mobile World Congress 2026. This
demonstration aims to showcase the capability of vehicles to maintain voice connectivity even when cellular networks are unavailable or unreliable. The initiative is part of a broader effort to integrate always-on connectivity into modern software-defined vehicles (SDVs), enhancing driver safety and emergency access. The demonstration will utilize Viasat's satellite network, Cubic³'s global connectivity management platform, Qualcomm's Snapdragon Auto 5G Modem-RF Gen 2 platform, and Fraunhofer IIS's NESC voice codec. This collaboration builds on a previous partnership between Viasat and Cubic³, announced in June 2025, which combined satellite and terrestrial connectivity to support global vehicle communications.
Why It's Important?
The demonstration of satellite-enabled voice calls for connected vehicles is significant as it addresses a critical need for reliable communication in areas where cellular networks are insufficient. This technology ensures that drivers can access emergency services and maintain safety communications regardless of their location. The initiative also represents a step forward in the evolution of connected vehicle technology, meeting the growing consumer demand for seamless data services. By extending voice services beyond traditional cellular coverage, automakers can enhance the safety and convenience of their vehicles, potentially leading to increased consumer trust and adoption of connected vehicle technologies. Furthermore, the collaboration among industry leaders like Viasat, Cubic³, and Qualcomm Technologies highlights the importance of partnerships in advancing global connectivity standards for the automotive sector.
What's Next?
Following the demonstration, Viasat and Cubic³ plan to continue their collaboration to bring future 5GNR satellite services, such as video streaming and seamless voice calls, to the automotive market. The partners aim to leverage Equatys, a jointly held entity by Viasat and Space42, to enable seamless 5G connectivity across satellite and terrestrial networks. This development is expected to extend services to billions of people and devices globally, further integrating satellite technology into everyday vehicle communications. As consumer expectations for data services continue to rise, the automotive industry may see increased investment in satellite-enabled technologies, potentially leading to new standards and regulations in vehicle connectivity.
