Development of a drone to restore mobile phone communication in the event of a disaster SoftBank August 31 20:14
Drones have been developed to quickly restore mobile phone communications in areas affected by major disasters such as typhoons, and we are aiming to put them into practical use in the future.
This drone was developed by SoftBank, a major mobile phone company, and is equipped with a relay system that connects base stations in the vicinity wirelessly.
On the 31st, the flight was released to the press in Ichihara City, Chiba Prefecture, and the drone reached a height of 100 meters above the ground in about 50 seconds.
It can fly for more than 50 hours and can restore communication within an hour at the lateest possible time after arriving at the site, allowing approximately 2000 people within a 10-kilometer radius to communicate at the same time.
In addition, a drone was released to search for people missing from the location information of mobile phones, and radio waves from mobile phones buried in debris and debris were detected and checked on a monitor.
Teruya Fujii, who was in charge of the development, said, “I think it is a technology that can contribute to many people in the event of a major disaster. We would like to continue our research and development to improve the accuracy of our technologies.”
With regard to securing communications in the event of a disaster, NTT DOCOMO is developing base stations that can cover a wider area than ever before, and KDDI is also moving to strengthen measures among major telecommunications companies, such as operating ships equipped with base station functions.
