China Mobile deploys drones to restore mobile communication in flooded areas.
Recently, the northern regions of China were hit by severe floods, leading to network and mobile communication disruptions in many cities and rural areas, leaving residents unable to contact the outside world.
On the morning of August 4th, the residents in the worst-hit areas on the outskirts of Beijing received a mobile text message from China Mobile:
“Dear customers, due to the heavy rains causing communication disruptions, China Mobile has urgently dispatched unmanned aerial vehicles (UAVs) that have arrived in your area’s airspace. Mobile public network communication can now be temporarily restored. During this period, you can use your mobile network normally, but please be aware of the UAV’s limited hovering time. Please contact your family as soon as possible. Our staff is still working tirelessly on repairs. Stay safe!”
At 11:37 am on August 4th, a DG-M20 series fixed-wing emergency communication drone equipped with the Beijing Mobile emergency communication system quickly took off from Gaoyakou Village in Changping District, Beijing, which had been severely affected by the floods.
The DG-M20 series fixed-wing emergency communication drone with its high-altitude base station represents a new form of emergency communication aimed at swiftly restoring communication after disasters and enhancing emergency communication capabilities.
When widespread communication disruptions occur due to natural disasters such as earthquakes and floods, the drone deploys the base station equipment at an altitude of 200 meters, ensuring communication signal coverage within a maximum radius of 3 kilometers.
It can hover uninterrupted for over 4 hours and support up to 1400 simultaneous user connections.
When combined with the versatile off-road satellite emergency vehicle, it can break free from constraints like optical cables and power supply, leveraging the Apstar-6D communication satellite launched by China to establish all-weather, all-time, cross-regional communication support capabilities, achieving seamless communication between ground and sky.
According to China Mobile, the UAV was urgently transported 1000 kilometers from Anhui province to Beijing by China Mobile Group.
After intense local data adaptation and multi-system coordination, the drone has officially been put into action for emergency communication and restoration efforts.
