Japan’s flying 5G mobile base station to take off in 2025
The next-generation telecom equipment will expand connectivity in the sky and at sea.
Japan is considering the deployment of flying telecommunication base stations by 2025. These stations, operated through unmanned aerial vehicles in the stratosphere, aim to deliver expansive network coverage, enhancing connectivity across various regions.
The recent World Radiocommunication Conference agreed to adopt four frequency bands as international standards for airborne base stations.
Japan has proposed the four frequencies using the technology called high-altitude platform stations (HAPS), whose development is being driven by the country.
Based on the proposal, the frequencies of 1.7 gigahertz, 2 GHz, and 2.6 GHz will be used globally for flying base stations.
Meanwhile, the 700 to 900 megahertz "platinum" band, which allows for improved mobile services, will operate in Europe, Africa, the Americas, and parts of Asia.
Compared to a ground-based station which has a coverage range of 3 to 10 kilometres, HAPS unmanned vehicles offer an estimated coverage of 200 kilometres and fly at altitudes of 18 to 25 kilometres in the stratosphere to act like cellular base stations.
