In the fast-evolving world of connected vehicles, achieving seamless communication has become more than just a convenience—it’s a cornerstone of safety, autonomy, and enhanced user experience. LG Electronics recently took a significant leap in this domain by showcasing its satellite-based Internet of Things Non-Terrestrial Networks (IoT-NTN) solution during the 2025 5G Automotive Association (5GAA) conference held in Paris. This breakthrough exemplifies how satellite integration can extend traditional terrestrial network capabilities, pushing the boundaries of vehicle connectivity to new frontiers.
The demonstration featured a vehicle equipped with LG’s next-generation IoT-NTN-based Telematics Control Units (TCUs), enabling uninterrupted voice communication even while moving through various locations across Paris. This real-world setup reflects the growing necessity for vehicles to maintain robust connectivity regardless of geography, ensuring that drivers and passengers stay connected, safe, and informed at all times.
Traditionally, connected vehicles have depended heavily on terrestrial cellular networks to support services like cloud-based applications, navigation, infotainment, and vehicle diagnostics. While these networks work well in urban and suburban settings, coverage gaps remain a persistent challenge in rural, mountainous, or otherwise remote regions. This issue translates into more than inconvenience; it can hinder safety features such as real-time traffic alerts, emergency notifications, and the operation of autonomous driving systems that require constant data exchange.
LG’s IoT-NTN technology addresses this critical gap by embedding satellite communication capability directly into the vehicle’s telematics system. This integration creates a dual-channel communication model that combines terrestrial networks with satellite links, offering a seamless and continuous data flow. Vehicles equipped with this system can switch between satellites and ground-based networks effortlessly, maintaining service continuity without dropouts or latency issues.
One of the most striking benefits of this satellite-terrestrial hybrid system lies in its enhancement of Vehicle-to-Everything (V2X) communication. For autonomous driving and advanced driver-assistance systems (ADAS), uninterrupted V2X data exchange is crucial to respond effectively to rapidly changing road conditions. With IoT-NTN, vehicles receive real-time updates and safety alerts even when conventional networks falter, reducing the risk of accidents caused by communication breakdowns.
The demonstration’s highlight—the ability to maintain high-quality voice communication over non-terrestrial networks while the vehicle was in motion—signals a major milestone. Reliable voice data transmission is fundamental to interactions such as vehicle-to-infrastructure communication and emergency calling, both vital for the next generation of autonomous mobility. This proof-of-concept in a bustling city environment like Paris underscores the system’s practicality and robustness.
Beyond safety and connectivity, LG’s innovative telematics setup enriches the overall in-vehicle experience. The company’s control units serve not only as communication hubs but also as platforms integrating infotainment services, navigation precision, and real-time vehicle diagnostics. The result is a smarter cabin environment where drivers and passengers enjoy continuous access to streaming services, accurate routing, and personalized content without interruption, regardless of location.
Collaborating closely with industry partners under the banner of the 5G Automotive Association, LG is actively shaping the standards and frameworks needed to commercialize these cutting-edge mobility technologies. The consortium’s collective efforts highlight a shift in the automotive landscape—from isolated product development toward ecosystem-level innovation that prioritizes interoperability, security, and user-centric design.
This progressive approach aligns with broader trends that position vehicles as “smart living spaces,” transforming them from mere transportation devices into personalized environments for work, entertainment, and communication. By leveraging cloud-based platforms and artificial intelligence alongside IoT-NTN connectivity, LG envisions vehicle interiors adapting dynamically to occupants’ preferences and needs.
Looking at the bigger picture, LG’s satellite-integrated telematics solution illustrates the convergence of space technology and automotive innovation—a fusion that promises to eliminate traditional connectivity blind spots on every road. As modern vehicles increasingly depend on continuous data streams for navigation, safety, and autonomous functionalities, seamless network coverage becomes indispensable. Satellite communications offer that critical extension beyond the physical limitations of terrestrial infrastructure.
Moreover, this development dovetails with global initiatives focused on smart cities, zero-emission transport, and intelligent traffic management systems. By enabling persistent connectivity, IoT-NTN supports these broader ambitions of sustainable, efficient, and human-centered mobility ecosystems. Vehicles can communicate with urban infrastructure, emergency services, and other connected devices in real time, fostering safer and more responsive traffic environments.
LG’s cloud-connected platform, serving as the backbone for integrating IoT-NTN with standard networks, further elevates service reliability and user experience. It ensures that data streams remain secure, synchronized, and optimized while enabling smooth transitions between coverage zones. The 2025 5GAA event demonstration offers a glimpse into a future where such telematics platforms are the norm rather than exceptions.
In essence, LG Electronics’ pioneering work signals a new chapter for connected vehicles—one where connectivity knows no geographical limits, and the promise of safe, intelligent, and immersive mobility can be realized anywhere. By combining satellite-backed communications with advanced telematics and cloud services, LG not only extends the boundaries of vehicle connectivity but also fundamentally reshapes the driving experience.
This breakthrough embodies the relentless pursuit of safer roads and smarter journeys, marking LG’s role as a trailblazer in the digital transformation of the automotive industry. As the roads ahead get smarter, LG’s IoT-NTN solution ensures vehicles stay connected, vigilant, and ready for whatever comes next. Case closed, folks.
