According to the latest data from the Ministry of Industry and Information Technology, the total number of 5G base stations in China has reached 4.042 million, accounting for 32.1% of the total number of mobile base stations and ranking first in the world in terms of network scale; The related applications have covered 74 major categories of the national economy. In addition to the large-scale replication of mature 5G applications, low altitude economy has also become a major focus of the industry in the exploration of various new application scenarios. Currently, China is building the world's largest low altitude communication network. Ambulances are currently the latest mobile rescue and resuscitation units, and various ventilators, monitoring devices, and other equipment on board can be remotely connected to the hospital's command center through 5G networks. At the same time, a first aid drone device has been installed on the top of the vehicle, which can transport blood samples from patients and medical supplies needed on board before arriving at the hospital during the vehicle's operation, thus maximizing the efficiency of first aid. Medical emergency has become one of the ten typical application scenarios for low altitude economy that have been clearly established in the industry. In the top ten scenarios, applications have also been implemented in areas such as low altitude logistics, low altitude travel, and airspace supervision. On October 12th, 15 cities including Beijing, Shanghai, Chongqing, Hangzhou, and several state-owned enterprises jointly announced that they will build a nationwide low altitude comprehensive operation platform and create 100 industry benchmark demonstration projects in the future. Li Xiaofan, General Manager of 5G IoT Products Department of China Mobile's Government and Enterprise Business Unit: A route from Shenzhen to Zhuhai uses unmanned aerial vehicles for cross sea flights, reducing the originally 3-hour journey to 20 minutes, which can greatly save travel efficiency and promote the development of low altitude applications from small to large, from cargo to passenger, from special to civilian. Industry experts have introduced that low altitude application scenarios require ground network signals to be covered up to hundreds of meters. Currently, more than 330 cities in China have launched the latest 5G-A network deployment, which will create the world's largest low altitude communication network. Ding Haiyu, Vice President of China Mobile Research Institute: By adding radar sensing function to the communication module of 5G base stations, it is possible to better identify targets, integrate and reuse air and ground resources, and meet the needs of low altitude economic networking.
