LG Demonstrates IoT-NTN Satellite Car Connectivity at 2025 5GAA Conference
Less than two weeks ago, LG Electronics unveiled a breakthrough in satellite-powered vehicle communications at the 2025 5G Automotive Association (5GAA) Conference in Paris. The company presented its next-generation Internet of Things–Non-Terrestrial Network (IoT-NTN) technology, conducting a live demonstration in a moving vehicle throughout the city—marking a major milestone in real-time voice communications for connected cars.
The demo showcased seamless, two-way voice conversations in real-time as the vehicle transitioned between traditional terrestrial networks (TN) and non-terrestrial networks (NTN), such as satellite and high-altitude platforms. It marked the first successful test of continuous voice communication in a moving car across both TN and NTN environments.
Bridging Connectivity Gaps with IoT-NTN Technology
The core of LG’s solution is an advanced IoT-NTN communications system, which integrates satellite-based networks to ensure connectivity in locations beyond the reach of standard cellular infrastructure like 3G, 4G, or 5G. This includes rural regions, oceans, deserts, and disaster zones—areas where terrestrial coverage is minimal or compromised.
Such capabilities are essential for modern applications in autonomous driving, emergency response, vehicle tracking, and remote operation—critical functions where communication continuity can save lives and maintain operational efficiency.
AI-Enhanced Voice Transmission
A key innovation featured during the event was LG’s AI-powered voice compression. Traditionally, satellite networks could only handle short emergency texts due to bandwidth limitations. LG’s AI solution dramatically compresses voice data, making voice message transfers over 10 times faster than earlier methods.
This enhancement allows drivers or passengers to initiate a voice-based emergency call with a single button press—eliminating the need to type during high-stress situations. Users can clearly describe emergencies in real time, even in areas with no traditional signal coverage.
Real-World Demonstration
LG installed both TN and NTN zones throughout Paris, enabling participants to test the system live. Attendees could send and receive voice messages between terrestrial and non-terrestrial zones while on the move, experiencing the seamless transitions firsthand. The system’s performance relied on IoT-NTN-powered Telematics Control Units (TCUs) installed in the test vehicle, supported by a cloud-based service platform for enhanced satellite communication and terrestrial integration.
This real-world showcase underscores the readiness of satellite-enhanced vehicle communication for broader deployment, especially in mission-critical transportation and logistics sectors.
Leadership in Connected Mobility
According to LG’s internal analysis referencing data from Strategy Analytics, LG captured 24.4% of the global telematics market last year, ranking it as the world’s top supplier in this category. The company’s portfolio spans telematics, Vehicle-to-Everything (V2X) communications, and in-vehicle infotainment, all essential for next-generation, software-defined vehicles.
LG’s efforts are part of a broader industry movement led by the 5G Automotive Association (5GAA), of which LG has been a member since its founding in 2016. The 5GAA is a cross-industry alliance of over 110 companies—including automotive OEMs, telecommunications providers, chipset makers, and infrastructure vendors—collaborating to develop 5G-based solutions for future mobility.
Executive Remarks
“Our IoT-NTN technology represents a leap forward for seamless, reliable connectivity for vehicles in the most remote or challenging environments,” said Lee Sang-yong, head of the VS R&D laboratory at LG Vehicle Solution Company. “By enabling real-time voice communication via satellite, we’re not only enhancing driver safety but also laying the groundwork for the next generation of connected mobility solutions.”
