Drones to support mobile communications www3.nhk.or.jp
Japanese telecom giant NTT Docomo is planning to use drones to support mobile phone communications in the event of natural disasters.
Quakes and torrential heavy rain can damage land-based communication facilities. Such a problem occurred in Kyushu, southwestern Japan, during record rainfall in July.
NTT Docomo is planning to test whether drones carrying relay equipment could temporarily replace the functions of wireless networks.
If the trial goes smoothly, the carrier plans to ask the government to consider a legal revision. The current law does not allow moving equipment like drones to be used as relay stations.
NTT Docomo official Tadashi Ikeda says people expect wireless signals to be available at all times. He says it's important for services to continue undisrupted under any circumstances.
NTT Docomo also plans to reroute communication cables laid under bridges, after seeing a number of them get washed away by floods caused by heavy rain.
