Airbus Tests 5G Connectivity from Earth Orbit
Airbus subsidiary UpNext has launched a demonstrator named SpaceRAN to explore advanced 5G connectivity capabilities via non-terrestrial networks. Initial results are expected by 2028, according to the press release.
Exploring Non-Terrestrial 5G Networks
The Airbus UpNext SpaceRAN demonstrator aims to enable standardized global connectivity by exploring the capabilities of non-terrestrial 5G networks, the company states. The system relies on software-defined satellites that can be reprogrammed from the ground after launch. The stated goal is to process data directly in space rather than merely relaying it, which should reduce latency and maximize throughput, according to the group. This technology is described as compatible with various types of applications, whether commercial, defense, or governmental. The device must confirm the feasibility of standardized, interoperable, and globally available universal connectivity.
Implications for Commercial and Government Sectors
According to Michael Augello, CEO of Airbus UpNext, this technology could enhance the operational efficiency of commercial aviation and simplify interoperability, while offering new passenger experiences. For military and government sectors, the system aims to provide more resilient and secure communications, which should facilitate situational awareness and accelerate real-time decision-making, as per the company's statements. The demonstrator plans two test platforms, the release specifies: a ground test bench designed to simulate the behavior of satellites in low Earth orbit, and a regenerative payload deployed on an Airbus satellite in low orbit, serving as a 5G space base station.
Collaborative Effort and Future Prospects
To successfully carry out this project, Airbus has assembled a consortium of partners including Aalyria, AccelerComm, CesiumAstro, Deutsche Telekom, Eutelsat, the Industrial Technology Research Institute of Taiwan, Keysight Technologies, Onati, Radisys, Sener, and ST Engineering iDirect. The demonstrator is part of the Air!5G project, supported by the French government through the France 2030 investment plan in the Future Networks strategy component. Initial results are expected by 2028. This project is also intended to help prepare for the next generation of wireless technology, 6G, and ultimately reduce the cost of transmitting orbital data, the press release indicates.
