In a landmark development announced on March 14, 2025, the Industrial Technology Research Institute (ITRI) has unveiled its latest advancement in the telecommunications arena with the launch of multi-orbit 5G Non-Terrestrial Network (NTN) trials. Conducted in partnership with several key industry players, these trials mark a significant milestone in the integration of satellite technology with 5G connectivity, paving the way for widespread adoption and technological maturity.
Overview of ITRI’s Pioneering 5G NTN Trials
The trials conducted by ITRI in collaboration with entities such as Eutelsat, MediaTek, and Airbus involve the use of low Earth orbit (LEO) and geostationary (GEO) satellites to establish a robust 5G air interface. This interface has successfully demonstrated its capability in supporting seamless communication through MediaTek’s NR-NTN test chip and ITRI NTN gNB over a Ku-band link. The achievement underscores the feasibility and efficiency of 5G NTN technology in diverse orbital environments.
Key Partnerships and Technology Breakthroughs
Strong collaborations have underpinned these groundbreaking trials, with Chunghwa Telecom joining hands for the GEO satellite segment and leveraging commercial satellite ST-2 for achieving high spectrum efficiency in a challenging propagation environment. The trials not only tested but also validated end-to-end bi-directional video calling capabilities, thereby illustrating the transformative impact of 5G NTN. The involvement of global technology leaders highlights a shared commitment to evolving 5G connectivity landscapes.
Future Implications for 5G NTN Connectivity
With these trials, ITRI is setting the stage for broader, more efficient deployment of 5G services capable of bridging terrestrial and satellite networks. This integration is expected to open up new markets across various sectors, including smartphones, automotive, and the Internet-of-Things (IoT). The successful implementation of these standards will facilitate a smoother, more connected user experience, thus shaping the future of global digital connectivity.
As we look ahead, the innovations by ITRI and its partners are poised to revolutionize the approach towards 5G NTN connectivity, enhancing the way we connect globally. Cementing Taiwan’s position at the forefront of telecommunications innovation, these developments promise to redefine the possibilities within the tech sphere, firmly anchoring future advancements in an increasingly interconnected world.
