5G-NTN connection tested via GEO satellite

The Fraunhofer Institute for Integrated Circuits IIS has successfully tested a 5G-NTN connection (Non-Terrestrial Network) in the Ka-band via the geostationary satellite Heinrich Hertz. During this communication test, impressive data rates of up to 137 Mbit per second were achieved. The test represents a significant advancement in the use of satellites for mobile communication and demonstrates the potential of GEO systems in future network infrastructures.

The focus of the test was on bandwidth, beam handover, and the role of geostationary satellites in future 3D networks. These technologies are crucial for addressing the challenges of mobile communication in rural and hard-to-reach areas. The results of the test could help reduce the digital divide between urban and rural regions.

Technological Advances in 5G

The 5G technology has made significant progress in recent years, and the integration of satellite communication is an important step in the further development of this technology. The ability to transmit high data rates via satellites opens up new application possibilities, particularly in areas such as the Internet of Things (IoT) and autonomous mobility. The tests conducted by Fraunhofer IIS are a testament to the innovative strength in German research and development.

Another aspect of the test was the beam handover, which allows for seamless switching of the connection between different satellites or transmission units. This is particularly important for applications that require a continuous connection, such as in aviation or mobile applications at sea. The successful beam handover during the test shows that the technology is ready to be deployed in real-world applications.

The role of geostationary satellites in future 3D networks is becoming increasingly important, as they can provide a stable and reliable connection. These satellites are positioned at a fixed location above the Earth and enable uniform coverage of large geographical areas. The combination of 5G technology with geostationary satellites could form the basis for new communication infrastructures that cover both urban and rural areas.

Outlook on Future Applications

The results of the test could have far-reaching implications for the development of communication services, particularly in regions that have been underserved so far. The ability to offer 5G data rates via satellites could help improve access to digital services and create new business opportunities. Companies and organizations could benefit from this technology to expand their services and tap into new markets.

Research at Fraunhofer IIS will continue to optimize the technology and develop new applications. The integration of satellite communication into existing mobile networks could significantly enhance the efficiency and reach of these networks. Advances in satellite technology and 5G development could lead to a revolution in the communications industry in the coming years.

The test was conducted with the geostationary satellite Heinrich Hertz, which plays a key role in testing new communication standards. The results of the test are an important step towards a more comprehensive use of satellites in modern communication.
