On Thursday, July 16, 2026, global satellite communications provider Viasat, Inc. announced a successful technical demonstration of the first-ever automotive satellite voice call fully integrated into a commercial vehicle’s infotainment system.
Conducted during the 5G Automotive Association (5GAA) Meeting Week in Munich, Germany, the live test utilized the in-vehicle platform of a BMW iX3 to showcase how standards-based satellite systems can bridge terrestrial cellular gaps for consumer vehicles.
Munich Demonstration Technical Parameters
The integrated voice call was completed using a combination of hardware and software designed to interface with existing automotive electronics:
- In-Vehicle Integration: Integrated directly into the BMW iX3 dashboard, allowing users to initiate, manage, and terminate satellite calls using the stock infotainment interface.
- Constellation Network: Routed data packets over Viasat’s geostationary L-band satellite network.
- Communications Protocol: Utilized Narrowband Internet of Things (NB-IoT) Non-Terrestrial Network (NTN) standards defined under 3GPP Release 17 guidelines.
- Chipset and Processing: Powered by Qualcomm Technologies’ Snapdragon Auto 5G Modem-RF Gen 2 platform paired with software-defined vehicle (SDV) eSIM profile switching from Cubic3.
- Acoustic Compression: Employed the Fraunhofer IIS NESC AI voice codec to transmit high-intelligibility voice streams over narrow, low-bandwidth NB-IoT channels.
Evolutionary Steps for Connected Car Systems
The demonstration marks a direct advancement over the 5G Automotive Association’s (5GAA) prior connected-vehicle trials in mid-2025. While earlier research successfully verified simple text-based emergency SOS messages over non-terrestrial bands, the integration of an active voice codec within the vehicle’s standard electronics suite validates that low-bandwidth satellite links can support real-time voice communications.
This allows automakers to plan emergency backup channels, over-the-air firmware updates, and fleet tracking services without adding high-gain external tracking antennas to the car roof.
Executive Insights on Standards-Based Integration
The standards-based approach allows global automotive manufacturers to streamline their telematics architectures.
“This demonstration reflects broader industry excitement to ensure consistent, resilient satellite capabilities for next-generation vehicles,” said Sandeep Moorthy, Senior Vice President, Advanced Non-Terrestrial Solutions at Viasat. “By bringing standards-based NTN to vehicles, we can integrate satellite voice and messaging and ultimately enable a future where drivers can remain connected — wherever the journey takes them.”
Transition Timeline to 5G-NR
The participating partners, who remain active members of the 5GAA, are aligning their roadmaps to support commercial vehicle integration within the next several product cycles. Under current 5GAA timelines, initial factory-installed IoT NTN capabilities are projected to enter the automotive market as early as 2027. Future phases of the program will focus on adopting 5G New Radio (5G-NR) satellite protocols. This progression is intended to enable higher data-rate applications, seamless transitions between cell towers and orbiters, and standard in-car media streaming in remote locations.
