On the 14th, at a drone test site in Daecheon-dong, Buk-gu, Gwangju, a 5G hydrogen drone from the domestic drone company Hogreen Air landed after a test flight carrying coffee. Hogreen Air, currently engaged in investment activities in the United States since the 10th, successfully remotely controlled two drones in Korea from Silicon Valley, USA, approximately 9,042 km away. The remote control system used in this demonstration utilizes 5G and LTE mobile communication networks, allowing it to be used anywhere in the world with mobile networks installed, regardless of distance.
