Japanese POC Demonstrates First Adaptive Satellite–5G Network Integration
A consortium of Japan Radio Co. (JRC), SKY Perfect JSAT, the University of Tokyo, and the National Institute of Information and Communications Technology (NICT) have successfully demonstrated a Satellite 5G network that can automatically switch between space and ground connections while maintaining reliable service, even under changing conditions.
The proof-of-concept combined Geostationary (GEO) and Low Earth Orbit (LEO) satellites with local 5G links to test dynamic routing and quality management. In simulated disaster scenarios, the system seamlessly rerouted traffic between networks, keeping video links and remote robot operations online without interruption.

The achievement shows how adaptive hybrid networks could form the backbone of Beyond 5G communications, supporting emergency response, remote industries, and resilient national infrastructure.
NICT, which leads Japan’s Beyond 5G research, also highlighted growing collaboration with the European Space Agency (ESA), signalling a push for international cooperation on integrated non-terrestrial networks.
