On the evening of August 11, the 2022 World 5g conference closed, but the new cooperation curtain has been opened. Hu Changsheng, governor of Heilongjiang Province, said that the conference fully demonstrated the latest achievements of the world's 5g development, presented the latest progress of the current 5g application, and collided with the latest viewpoints in the 5g field. Not only that, as the host of the 2022 World 5g conference, Heilongjiang has introduced high-quality innovation resources for itself. Leading enterprises such as Huawei, Tencent, Baidu, Qianxin, and digital economy investors such as telecom operators have crossed the mountain and sea to lead the investment in Longjiang digital manufacturing, digital services and new infrastructure projects. At the closing ceremony of the conference, 39 projects were signed, with a signed amount of 33.21 billion yuan. The current 5g conference has come to an end, but the results of the conference will have a profound impact on the development process of 5g in China and the world, and will also give continuous innovation impetus to Longjiang and Harbin. A large number of typical applications have emerged. The Longjiang 5g digital farm project, jointly built by Beidahuang group and China Unicom Heilongjiang Branch, won the second prize of the enterprise group of the "5g integrated application unveiling competition" of the 2022 World 5g conference. Under the sun, the wind blows over the rice waves, and a piece of gold rolls. It is rare for farmers to work. Intelligent equipment such as leaf age intelligent detection, security camera, field monitoring sensor, 5g plant protection UAV / UAV field patrol have replaced them. "5g network has covered the whole farm, supporting intelligent monitoring and management of farmland." Yu Yang, general manager of the intelligent agriculture business department of Heilongjiang Unicom Industrial Internet Co., Ltd., introduced that the 5g digital farm project of "big country granary" runs through the whole link of "cultivation and management of income", and has opened up all the elements of "people, land, machinery, materials and environment" production operations. It has been demonstratively deployed in five farms of Beidahuang group, covering a total of 23000 mu of arable land. Meng Qi, director of the intelligent agriculture business department of Heilongjiang Unicom Industrial Internet Co., Ltd., calculated an economic account for the reporter. Through standardized and scientific planting management, the increased income per mu can be 200 to 300 yuan. The research on enabling Rural Revitalization by 5g and related frontier technologies released by the "5g and digital agriculture and rural forum" of the 2022 World 5g conference points out that a large number of typical applications of 5g technology have emerged in the aspects of enabling agricultural modernization, better life of farmers and rural governance. In fact, 5g technology has played an enabling role in many industries such as industry, energy, medical treatment, education and transportation. By June 2022, there were more than 20000 innovation cases of 5g application in China. "5g is an enabling technology. In the future, 20% of the market will be at the consumer end and 80% of the market will be at the industrial end." Zhou Ji, academician of the Chinese Academy of engineering, expressed this view at the "5g and industrial revitalization forum" of the 2022 World 5g conference, which shows the industry's judgment on the application prospect of 5g technology. Wu Hequan, academician of the Chinese Academy of engineering and chairman of the future mobile communication forum, said: "China's 5g construction has made breakthrough achievements and has entered all aspects of social life. With the accelerated implementation of 5g applications, new industries, new formats and new models will emerge." The next stage of development still has a long way to go. Wu Hequan told the science and Technology Daily reporter: "the world 5g conference has entered
