The European Space Agency and Telesat have achieved a groundbreaking milestone by successfully testing a 5G signal from a low-orbit satellite, paving the way for seamless global connectivity.

In a remarkable feat of technological innovation, the European Space Agency (ESA) and global satellite operator Telesat have successfully tested a 5G signal directly from space. This historic experiment, the first of its kind, connected a low Earth orbit (LEO) satellite to ground-based transmitters, demonstrating the potential of 5G Non-Terrestrial Networks (NTN) to revolutionize global communications. Conducted at the ESA's Communication Technologies Laboratory in the Netherlands, this breakthrough marks a significant leap in expanding the possibilities of 5G connectivity.

Groundbreaking Test with LEO Satellite


The test involved the LEO 3 satellite, operated by Telesat, and used Amarisoft's cutting-edge 5G technology. The team achieved and maintained a stable connection to the satellite as it traversed its orbit, from near the horizon to an altitude of 38 degrees and back toward the horizon.

This achievement distinguishes itself from previous experiments with geostationary satellites by implementing 5G NTN technology in low Earth orbit. Unlike geostationary satellites, which remain fixed relative to the Earth, LEO satellites move rapidly, posing unique challenges for maintaining seamless connectivity.

5G NTN: The Future of Global Connectivity


The success of this test showcases the potential of 5G Non-Terrestrial Networks to transform telecommunications. Operating in the Ka-band frequency spectrum, this technology enables two-way real-time communication, unlocking possibilities previously deemed unattainable.

According to the ESA, the integration of standardized 5G technology with low-orbit satellites can support critical services such as emergency response, rural healthcare delivery, and remote business operations. Applications could include connecting autonomous vehicles, enabling remote medical procedures, and providing in-flight internet access to passengers anywhere in the world.

Open Standards for a Seamless Future


A notable aspect of this achievement is its foundation on open standards established by the international telecommunications body, 3GPP. This standardization ensures that future mobile devices could connect directly to satellites, simplifying terrestrial infrastructure and reducing costs.

The technology also enables seamless transitions between terrestrial and satellite networks, offering uninterrupted connectivity whether in bustling urban centers or remote wilderness areas. The ESA envisions this innovation fostering greater interconnectivity between service providers and enhancing global communication coverage.

 Pioneering a New Era in Communication


The successful test of 5G signal transmission from space marks a pivotal moment for global connectivity. By demonstrating the feasibility of low-orbit satellite integration with 5G technology, the European Space Agency and Telesat have laid the groundwork for a future where seamless communication is possible anywhere on Earth.

From enabling emergency response in isolated areas to providing internet access aboard passenger planes, the potential applications of this innovation are vast. As the world moves toward greater reliance on digital connectivity, this milestone represents a significant step forward in bridging the gap between terrestrial and non-terrestrial networks.
