China Telecom and China Unicom recently announced that they will open 5g new call ultra clear video voice call service (vonr) in more than 100 major cities. Recently, China Mobile also said it would try out vonr. According to the data, at present, China has built and opened 1.559 million 5g base stations, and the 5g network has covered all prefecture level cities and county urban areas in China. Behind the bright report card, there are realistic and perceptible 5g application scenarios, which not only change people's lives, but also help thousands of industries to accelerate the transformation and upgrading. Promote the construction of base stations In April, in the late maturing navel orange forest in yuanlou village, Taiping Town, Tongliang District, Chongqing, orange fruits and white flowers complement each other, which is very beautiful. The live studio of Zhou yunfen, Secretary of the Party branch of yuanlou village, is opened here. "Have you ever seen such fruit trees with the same branches? You can enjoy the flowers and pick the fruit at the same time." She enthusiastically introduced to netizens. "In the past, the signals in rural areas were very poor. Since last year, 5g base stations have been built in the village, and the signals in all corners are full!" Zhou yunfen said that the villagers took advantage of the situation to start the live tape goods. The fertile oranges, navel oranges and beautiful scenery in the village were spread through the Internet, attracting many tourists and orders. According to the relevant person in charge of Tongliang District, up to now, 1580 5g base stations have been built in the district to achieve hot spot coverage in key areas such as urban areas, rural towns and some villages and communities. The live broadcasting room in the navel orange forest is a vivid epitome of the "accelerated running" of China's 5g construction. Recently, the data released at the press conference of the State Council Information Office showed that in the first quarter, 134000 5g base stations were added in China, with a total of 1.559 million completed and opened. The 5g network has covered all prefecture level cities and county urban areas in China; In the first quarter, the number of 5g mobile phone users added in China reached 48.11 million, with a total of 403 million, accounting for 24.3% of the total number of mobile phone users. Experts pointed out that in recent years, China has made positive progress in promoting the construction of digital information infrastructure. As an important part of the new infrastructure, 5g continues to expand its coverage, improve its service level, and gradually highlight its enabling role. After the outbreak of COVID-19, more 5g business needs such as home office, online education and telemedicine were generated, which also accelerated the construction of new infrastructure such as communication network. The Ministry of industry and information technology revealed that in the next step, it will steadily and orderly promote the construction of 5g and gigabit optical networks, deepen the co construction and sharing of networks, continuously improve the depth and breadth of network coverage, promote the construction of 600000 5g base stations throughout the year, and the coverage capacity of gigabit optical networks exceeds 400 million households. It will guide basic telecom enterprises to appropriately deploy 5g base station construction in advance, promote the formation of physical workload as soon as possible, and give full play to the role of investment. Change production and life At present, China is vigorously cultivating the "double Gigabit" network integration application of 5g and gigabit optical network. 5g, in particular, is accelerating its extension to production control. According to statistics, in the first quarter of this year, the total number of "5g + industrial Internet" projects under construction reached 2400. "Accelerating the large-scale application of 5g is a key measure to help the digital transformation of thousands of banks and industries and stimulate the new momentum of high-quality economic and social development." Gu rentao, a professor at Beijing University of Posts and telecommunications, said. "5g + industrial Internet" has become an important force to promote the digital transformation of enterprises. Sany Heavy Industry piling machine factory in Beijing is the world's first 5g fully connected factory in the equipment manufacturing industry. Here, 5g has been applied in production and manufacturing, visual management, smart logistics, smart Park, smart R & D, smart marketing and service, which runs through the whole business process, data-driven intelligent application, penetrates into every link of industrial production and manufacturing, comprehensively improves the intelligent level, and promotes the transformation from "made in China" to "made in China". With the support of 5g technology, distance education and other industries are also accelerating their development. Recently, in Ali middle school in Lhasa, Tibet, relying on the cloud school intelligent education service system built by China Telecom 5g network, teachers and students and Xi'an high tech No. 1 middle school, 2700 kilometers away, realized remote live broadcasting and interactive teaching. "5g +" has also penetrated into all walks of life of urban public services and become a "good helper" involved in urban management and public services. In Tangjing street, Baiyun District, Guangzhou, Guangdong Province, three mobile 5g unmanned distribution vehicles have been put into use to assist the community in transporting food and anti epidemic materials and ensure the "last kilometer" of material distribution. In shuangzhong Town, Hukou County, Jiujiang City, Jiangxi Province, the intelligent sanitation monitoring platform built on 5g technology can manage the work scope of sanitation workers and the operation of vehicles in real time, visually display the planning information of operation area, and provide safety assurance services for sanitation workers. Increase policy support Industry experts said that the large-scale development of 5g industry application still faces certain challenges, including the pressure of funds to promote 5g application and the maturity of the industrial chain; The digital foundation of small and medium-sized enterprises is weak, and the project implementation is difficult; Industry standards need to be improved, and cross-border integration needs to be further strengthened. In this regard, the government needs to strengthen policy and financial support, and local governments should speed up the introduction of supporting policies. In July 2021, the Ministry of industry and information technology, together with the central network information office and other 9 departments, issued the "sailing" action plan for 5g application (2021-2023), focusing on promoting the application of 5g in 15 industries such as industrial Internet, finance, education and medical treatment. This year's government work report clearly proposed to "promote the large-scale application of 5g". Recently, the Ministry of industry and information technology has put forward specific plans in improving the level of integrated application and exploring multi-party cooperation mechanism: the "ten hundred thousand" project of 5g industry application will be implemented, that is, 10 vertical industries will be selected, 100 benchmark demonstrations will be formed in each industry, and 1000 5g industry virtual private networks will be built; Hold 5g and gigabit optical network application innovation competition, focus on key industries, form innovative application demonstration benchmarks, add new consumption tracks, and strive to explore new highlights of information consumption; Governments at all levels are encouraged to increase policy support for land, electricity and employment in the development of 5g and other digital information infrastructure, and guide social capital to support application innovation. For the large-scale application of 5g, many places have issued action plans since this year. Recently, Shanxi Province officially issued the implementation plan for accelerating 5g integration application, which clearly promotes ten projects such as "5g + Intelligent coal mine" by integrating 5g into three major fields: Industrial digitization, intelligent life and digital governance. The Shaanxi 5g application "sailing" action plan (2021-2023) points out that 5g application results will be highlighted in the fields of personal consumption, vertical industries and social livelihood, and more than three 5g application benchmarks will be created in each key industry. Henan Province issued the work plan for promoting 5g large-scale application in the information and communication industry of the whole province in 2022, which made it clear that through the implementation of four actions of 5g integrated application, we should continue to improve the supply capacity of 5g products, improve the 5g application ecology, consolidate the 5g security foundation, and accelerate the large-scale development of 5g application.
