On June 6, the appointment of "radio and television 5g" friendly user number 192 was launched nationwide, and the construction of China's Radio and television 5g has entered the sprint of network opening and operation. Previously, China Radio and television and China Mobile have completed the construction of 200000 700m 5g base stations. This year, 280000 700m base stations will be completed. At that time, 700m 5g network coverage will be basically realized. On June 6, 2019, the Ministry of industry and information technology issued 5g commercial licenses to Chinatelecom, China Mobile, China Unicom and China Radio and television. Taking this as a starting point, China's new infrastructure and related applications represented by 5g entered the fast lane. Wangzhiqin, vice president of the China Academy of information and communications, said: "with the overall planning of the government and the concerted efforts of the industry, China has made outstanding achievements in 5g business, becoming a leading country in the global 5g technology industry, network construction and application innovation, and the supporting role of 5g in high-quality economic and social development has initially emerged." In the past three years, China's 5g network construction has expanded from wide coverage to deep coverage. 5g applications have been integrated into thousands of industries and services to the public. With the potential of a single spark starting a prairie fire, it is difficult for other markets in the world to match. Zhaoce, deputy director of the information and Communication Development Department of the Ministry of industry and information technology, introduced that at present, China has built more than 1.6 million 5g base stations in total. 5g signals cover all cities, counties, urban areas and 87% of towns and townships in the country. The total number of 5g Mobile phone users exceeds 413million; Typical 5g application scenarios with commercial value have covered 40 of the 97 major categories of the national economy, with a total of more than 20000 5g application cases; By the end of April, a total of 814 5g terminals in China had obtained network access licenses, including 569 mobile terminals; From January to April 2022, 5g mobile phones shipped in the domestic market totaled 68.469 million units, with 78 new models on the market. China's 5g construction has attracted worldwide attention. The "co construction and sharing" mode, which saves a lot of investment for the industry, has for the first time provided the world with a model of intensive social and economic development of communication systems. As Chen Sen, deputy general manager of China Tower communication development department, said, deepening resource sharing and reducing repeated construction are the original intention and value of China Tower. "In China's 5g construction, more than 97% of the station sites are shared, and more than 25% of the new tower projects use social tower resources." Chen Sen introduced that over the past three years, China's iron towers have undertaken to build more than 1.4 million 5g base stations, with a total investment of more than 30billion yuan. Now, they are accelerating the delivery of 2600 base stations a day. Over the past three years, Chinese telecom operators have made every effort to unblock the "artery" of social information. 5g innovative applications have blossomed everywhere, and 5g terminal shelves are dazzling. However, with the accelerated release of market demand and the increasing application scenarios, 5g still has a long way to go in the future. Wen Ku, vice president and Secretary General of China Communications Standardization Association, said: "Looking back at the milestone of the third anniversary, 5g's commercial speed has exceeded expectations, and the fruits have not come easily. The follow-up needs the joint efforts of the industry to promote the industrial development in an orderly manner through the comprehensive layout of technical standards and application industries. Both consumer applications and industrial digital businesses have put forward further demands for 5g's network capability and 5g's innovation capability, and the pace of 5g's enhanced technology research and development and application development will be significantly accelerated in the future." "In the past three years, we have witnessed the rapid development of 5g, as well as problems and challenges." Dinghaiyu, vice president of China Mobile Research Institute, pointed out that 5g has not yet emerged as a "killer application" on the consumer side, and its advantages over 4G are not fully reflected. The value of 5g still needs to be further demonstrated. On the industry side, the adaptation and support of industrial financing need to be further strengthened. At the same time, 5g industrial technology foundation needs to be further strengthened. "To truly unleash 5g potential and continue to lead, we need to focus on two key elements: application scenarios and integrated talents." Wangchunhui, a professor of Nanjing University of Posts and telecommunications, suggested that the national 5g technology and industry talent training plan should be formulated to strengthen the training of 5g composite talents and reserve human resources for the sustainable and healthy development of 5g. Professor gaoxudong, deputy director of the technology innovation research center of Tsinghua University, pointed out that 5g network, as a typical communication infrastructure, has a huge investment and needs the government and society to attach great importance to it and provide real support to relevant enterprises, especially operators.
