Viasat and Cubic³ will jointly demonstrate satellite-enabled voice calling capabilities for software-defined vehicles at Mobile World Congress 2026, marking a significant advancement in alternative connectivity solutions for the automotive sector. The demonstration, conducted in partnership with Qualcomm Technologies and Fraunhofer IIS, will showcase how vehicles can establish and maintain voice communications via satellite infrastructure when traditional cellular networks are unavailable or non-functional.
The technology addresses a critical gap in vehicle connectivity and safety, particularly for emergency communications in remote or underserved areas where cellular coverage remains limited or unreliable. By integrating satellite voice capabilities into software-defined vehicle architectures, the partnership demonstrates how automotive manufacturers can enhance vehicle resilience and ensure continuous access to emergency services regardless of network availability.
The development reflects broader industry efforts to create redundant communication systems for connected and autonomous vehicles, where uninterrupted connectivity is increasingly essential for both operational safety and passenger security. The Mobile World Congress demonstration will provide industry stakeholders with a practical view of how satellite technology can complement existing cellular infrastructure in next-generation vehicle platforms.
