News from China Electronic Information Industry Network:

China's 5g construction is about to go for two years. Up to now, China has built the world's largest information and communication network, opened 792000 5g base stations, and the number of 5g mobile terminal connections has reached 260 million. A key network integrating innovative technologies such as 5g, gigabit optical fiber and next-generation access has become a key enabler of social development. It not only plays an indispensable role in production and life, but also becomes the fundamental driving force to promote the flood of digital economy and activate the digital transformation of the whole industry.

Spawn a new round of changes in social entertainment

Amazon founder Jeff Bezos once said: "one thing I like customers is that they are always dissatisfied. Their expectations are never invariable, but increasing. This is human nature." For this reason, over the past 20 years, China's C-terminal digitization process has made rapid progress, and the digitization degree in many scenes such as life, work, study and entertainment has been continuously improved.

Chen Zhongyue, general manager of China Unicom, pointed out at the 2021 world ultra high definition video (4K / 8K) industry development conference: "70% of Internet traffic in the 5g era comes from video, and the quality of the Internet depends on video." 5g can truly solve the need to watch and share videos anytime, anywhere.

5g just downloads videos faster and plays games more smoothly? Of course not. In the 5g era, the link between people is an endless process. Under the background of technology upgrading and user demand improvement, a new round of changes has taken place in China's mobile social industry. The mobile social product ecology will be optimized and upgraded in terms of horizontal category extension and in-depth play innovation.

Tiktok and Kwai, etc, in the 5G mobile Internet era, make the short video industry develop rapidly and lead people into the era of video social interaction. Public data showed that the number of tiktok users reached 600 million, and the users' time was 30 for more than 30 minutes. Tiktok has increased from 1 million to 5 million since 2019.

The sudden novel coronavirus pneumonia has brought people unprecedented experience in hitherto unknown social value of 5G, AI, cloud computing and big data. Various applications based on 5g, AI, cloud computing and big data development have played a wide role: online education and online office, so that citizens who are closed at home do not stop work; The e-commerce platform ensures the sufficient supply of daily necessities and epidemic prevention supplies; The remote expert linkage in the shelter hospital has solved the pain points of temporary medical resources; Professional applications such as temperature detection and epidemic tracking can effectively help epidemic control.

Ignite industry application demand

The development and evolution from 1g to 4G meets the diversity of communication scenarios and brings faster and faster data transmission rates, but they all focus on the connection requirements dominated by "people". Different from 1g to 4G, 5g network has the ability to provide deterministic and differentiated services. 5g slice private network gives 5g the valuable value of enabling thousands of lines and industries. Whether in terms of customized network, resource exclusive, priority scheduling and security isolation, 5g network slice is a sharp tool to meet the differentiated network needs of all walks of life.

Dong Xin, general manager of China Mobile, said that looking back on 2019, we talked about 5g or "three or two blossoms at first", and now it is "full of spring and can't be closed". The data show that operators can obtain the value of up to $1.3 trillion through industrial applications, and 5g has become the key technology for the development of digital economy in the future.

"What users need is not 5g, but what practical problems can be solved in the process of 5g technology conversion." Dong Ming, vice president of Huawei China, said. Today, China's 5g construction is about to go for two years, and 5g application ecology has begun to emerge. 5g has accelerated its extension to various vertical industries. At present, it has been implemented in ports, mining areas, media, transportation, monitoring, education, industry 4.0 and other fields.

Shanghai Kangqiao logistics park covers an area of 100000 square meters. In the past, it took at least one month to complete a manual inventory. Now, the overall operation efficiency has been improved by 30% through 5g and other technologies; In 2019, Shenzhen Airport took off and landed an aircraft in less than one minute on average during the daily peak hours. After integrating 5g and other technologies, Shenzhen Airport built multiple subdivision scenario schemes, reduced ferry trips by more than 2.6 million throughout the year, and improved security inspection efficiency by 60%; In Xiamen, Ningbo and other ports, the driver has realized 5g remote gantry crane and tire crane operation, saying goodbye to the narrow working space

5g makes remote surgery possible and effectively improves the medical level. In March 2019, neurosurgeons in Hainan completed the first 5g remote surgery in China by using the high-definition pictures transmitted in real time by China Mobile 5g network. With a geographical distance of nearly 3000 kilometers, the operation of "brain pacemaker" implantation was successfully completed through remote control of surgical instruments. Magnetic resonance scanning confirmed that the implantation position of electrodes in the brain was accurate.

Over the past two years, successful 5g remote surgery has given confidence to the medical industry. Taking Shandong Province as an example, in December 2020, Shandong proposed to create a typical application scenario of 5g telemedicine in the medical and health industry, and carried out the application pilot of "5g telemedicine". From March 17, 2021, the series verification of "5g telemedicine" began in Shandong Province.

The prospect of rural 5g market is promising

Kiwi growers swipe the mobile phone screen with their fingertips and know the acquisition market of online subscription; When large grain growers open their mobile app, they can see the satellite aerial photos of their contracted "one mu and three parts of land" and check the seedling rate and growth in real time... With the establishment of the "information highway" extending in all directions by telecom operators, 4G telecom universal service and 5g enabling applications will bear fruitful results in more and more fields, and mobile phones have become farmers' "new farm tools", Data has become new agricultural materials.

At present, China has achieved full coverage of 5g network in cities above prefecture level, but county and countryside are still "blind areas" of 5g network. Recently, the opinions on comprehensively promoting rural revitalization and accelerating agricultural and rural modernization issued by the CPC Central Committee and the State Council clearly pointed out that the implementation of the digital rural construction and development project; Promote the synchronous planning and construction of rural gigabit optical network, fifth generation mobile communication (5g), mobile Internet of things and cities; We will improve the compensation mechanism for universal telecommunications services and support the construction of information and communication infrastructure in rural and remote areas.

In January this year, China Mobile signed a "5g strategy" cooperation agreement with China Radio and television, and officially launched the joint construction and sharing of 700MHz 5g network, which is undoubtedly a great benefit to the construction of rural 5g network.

Zhang Yunyong, general manager of China Unicom Group's product center, said in an interview with China Electronics News that the population density of rural environment is low, and it is impossible to deploy coverage with the same hot spot density as urban 5g coverage in the short term. The breadth and depth coverage characteristics of low-frequency resources represented by 700MHz and the delay advantages brought by FDD system can greatly reduce the network deployment cost and construction difficulty, and have irreplaceable advantages in building and improving 5g universal coverage in rural and remote areas.

The seventh national census data released recently shows that the population living in rural areas in China is 509 million, accounting for 36.11% of the total population. With the gradual improvement of telecom universal service and 5g fixed-point on-demand laying, we will build a rural economic development policy system integrating "knowledge renewal, technological innovation and data drive", optimize rural industry, rural education and rural medical infrastructure, improve the information service level of "agriculture, rural areas and farmers", and constantly stimulate the endogenous driving force and great potential of rural development, Promote the digital upgrading of agriculture and rural areas.
