Japanese Consortium Achieves World's First Demonstration of 5G Communication from Altitude of 4km Using 38GHz Band
The trial established an aerial relay backhaul line between the Cessna aircraft, flying at altitude of approximately 4km, and three ground stations, using the 5G New Radio (NR) standard*5 with 38GHz band radio waves, which is a novel approach for terrestrial 5G networks.

- The achievement of multiple backhaul line consisting of aerial relays using the 5G NR standard with 38GHz band radio waves was a world first in telecommunication technology*6.
- With 5G evolution underway and 6G implementation on the horizon, various efforts are being made to expand coverage areas.
- The demonstration is part of a project focused on wireless communication systems using HAPS led by Japan's Ministry of Internal Affairs and Communications*8.
