The testing of the potential use of drones during a tsunami or other disasters to help in prevention and mitigation efforts, verified that using a private LTE network to control and communicate with the drones is an effective means for enhancing situational awareness - and communicating with the affected population during a disaster.
Nokia says this is the first time in the world this type of trial has been conducted.
Sendai City is the centre of Tohoku Region, Japan, and lies northeast of Tokyo on Honshu Island, with a population of over 1 million. The coastal areas of the regionwere devastated by the tsunami caused by the Great East Japan Earthquake in 2011, and have come to be recognised internationally through the United Nations as a symbol of disaster risk reduction and reconstruction.
Nokia says it deployed a private LTE network near the Minami-Gamo Water Treatment Center using its plug-and-play digital automation cloud technology.
Using speakers, HD cameras and thermal cameras mounted on Nokia drones, the testers delivered recorded and real-time voice messages and conducted aerial monitoring using HD and thermal camera video streaming from the drones.
Nokia says that during the simulated disaster, the testers were able to issue a major tsunami warning to evacuees in coastal areas through the drone speaker, and monitor the tsunami arrival zone and coastal areas through drone camera images. They also guided people to evacuation sites using the drone to convey directions, and monitored the movements of evacuees using the drone camera.
The test also highlighted how first responders can facilitate disaster prevention and mitigation without risk to the personnel managing the evacuation activities.
Nokia Drone Networks is a turnkey solution consisting of one or several drones equipped with gimbals with HD and thermal cameras, a private LTE wireless network, a drone flight command and control center, and video analysis applications.
Nokia says private LTE/4G provides seamless and secure connectivity, making it more suitable for mission-critical use cases than the mostly Wi-Fi-based technology used in public mobile networks.
“The high-performance, low-latency connection provides optimised coverage for the drones, ensuring sufficient capacity for video streaming across wide areas and enabling secure information processing. Drones can also be flown over populated areas with limited risk and with better control in difficult weather conditions,” says Nokia.
Going forward, Nokia says the partnership with Sendai City will continue to promote the use of Nokia technologies to help improve the safety and security of citizens, revitalise local industries, and promote the technological development of local companies.
Sendai Mayor Kazuko Kohri, said: "The use of these drones seems to be very effective in ensuring the safety and security of Sendai and its surrounding areas. The demonstration by Nokia showed that we should be able to respond faster and provide better information to the people in the most affected areas during a potential disaster. We are very hopeful that Nokia Drone Networks will help us to reduce risk for our citizens."
“We are very pleased that we have successfully completed this drone flight demonstration with Sendai City, highlighting the effectiveness of using drones and private LTE for disaster prevention and mitigation,” said John Harrington, Head of Nokia Japan.
“Nokia Drone Networks has been adopted by the Red Cross in the Philippines as a social infrastructure for disaster relief operations. Based on this demonstration, we hope to contribute to disaster prevention and mitigation for Sendai City and other local governments in Japan.”
