"The new infrastructure construction is of great significance to the economic development of China. 5G network construction is an important part of new infrastructure construction. The combination of 5G with artificial intelligence, Internet of Things and cloud computing is conducive to promoting the development of the digital economy. " This is the conclusion drawn by Wang Jianzhou, the former chairman of China Mobile, on the development of 5G. As the former chairman of China Mobile and a senior consultant of the Global Association for Mobile Communications (GSMA), Wang Jianzhou has been deeply involved in the communication technology industry for decades, and has experienced every upgrade of mobile communication technology from 1G to 5G, and is known as "the person who knows 5G best in China". He has a unique view on the connection between 5G and new infrastructure, digital economy and enterprise innovation. In order to explore the application and innovation of 5G in the new infrastructure construction, China Science and Technology Information magazine interviewed Wang Jianzhou, former chairman of China Mobile.
Wang Jianzhou: In the value of 5G, 5G applications account for 95%. First of all, the basic application of 5G is to provide more data traffic. In the 4G era, the data traffic has changed a lot, that is, the per capita usage traffic is increasing. In 20 14 years, the per capita usage traffic is 1 g, and by 2020, the per capita monthly usage traffic has reached10 g. With the increase of traffic demand, the speed of 4G is also affected, resulting in a slow network speed. With the development of the Internet, people's demand for traffic is increasing, and the problem of slow network speed needs to be solved urgently. The emergence of 5G provides a solution to this kind of problem-using 5G, which is much faster than 4G, can not only meet people's demand for traffic, but also improve the network speed.
The second is the application value of 5G. At the beginning of 5G research and development, everyone was concerned about industry and enterprise applications. Before the emergence of 5G, the industry has been expecting what 5G can do, especially in the field of industrial applications. Many achievements envisioned at that time have now become a reality. At present, there are mainly intelligent control, intelligent logistics, security system, telemedicine, distance education and so on. As far as the 5G applications I am in contact with are concerned, the most promising is 5G intelligent control, specifically, it is to use 5G to remotely control the work with high safety production risks, such as mining, coal mining, dock loading and unloading, construction machinery and so on.
The third is the significance of consumption. For 5G, the development of consumer-oriented toC application is not complete, and the consumer market has not been fully opened. In the future, 5G will certainly cover the whole country or even the whole world like 4G, but the value of these networks can't be fully exerted only by industrial applications. It is necessary to develop consumer-grade applications in order to truly tap the value of these huge network resources. The biggest feature of 5G is to improve the network speed, ensure the network transmission speed, and promote the emergence of some new applications. For example, mobile payment and online car rental, which were not available in the 3G era, have been greatly developed in the 4G era. Similarly, many applications that cannot be supported by 4G will also usher in development opportunities in 5G, such as VR and AR. In the future, 5G will inevitably give birth to more consumer-grade applications, but these applications have not been completely unlocked in the consumer field, and the consumption value of 5G networks needs these new applications to discover and explore.
The development of 5G will also have a great impact on the communication industry. For example, the concept of mobile phone needs to be redefined. In the 5G era, mobile phones will no longer be just the communication between people in charge, but will extend to the communication between people and things, and the communication between things. The functions of mobile phones will extend from communication, social interaction, browsing and shopping, payment, navigation, verification, teaching and entertainment to the Internet of Things and artificial intelligence.
Wang Jianzhou: The demand for network in the development of digital economy has promoted the development of 5G. Digital economy is inseparable from network, and the development of network is the foundation of digital economy. During the epidemic period, people rely on the Internet for various activities, such as online office, online education and online entertainment. At this stage, people feel the importance of the network and deeply understand and feel the digital transformation. The epidemic situation has accelerated the digital transformation, and the development of digital economy has also stimulated people's demand for 5G networks and boosted the development of 5G.
Now the real development of 5G is mainly equipment vendors and telecom operators, such as Huawei, ZTE, China Mobile, China Telecom and China Unicom. One of the signs of the real development of 5G is that a large number of entrepreneurs and investors have entered this field. The application of 5G itself is a mobile Internet, which links all walks of life. More entrepreneurs and investors are needed to participate in the development of 5G applications, not just manufacturers and operators. I expect internet entrepreneurs to develop 5G applications together.
In the face of the rapid development of 5G, telecom operators should first assume the responsibility of building and operating 5G networks, overcome various difficulties and ensure the construction and coverage of 5G networks, which is their work and obligation. The construction of 5G network is not only related to the development of operators themselves, but also related to the digital transformation process of the whole society. Secondly, telecom operators also need to accelerate the pace of transformation. Although the operator is the earliest digital enterprise, its own operation and maintenance system has not changed much for so many years. The main problem faced by 5G is the high operation and maintenance cost. Operators should actively think about how to realize intelligent operation and maintenance and reduce costs. Now operators and manufacturers are trying to solve this problem. Huawei, ZTE and other companies have developed related technologies, which can dynamically and intelligently manage the network without affecting users' use.
The third point is that with the development of 5G, operators have to explore new business forms and expand their business scope. Nowadays, Internet companies not only focus on their core business, but also develop across borders and blossom in an all-round way. Telecom operators have made few attempts in this respect, and the development of 5G is a good opportunity. Operators should seize this opportunity, re-plan the strategic choice and layout, and realize business diversification.
Wang Jianzhou: Mobile communication itself is the result of the development of science and technology, and it also promotes the development of science and technology.
Mobile communication has a history of more than 40 years. The first generation of cellular mobile communication came into being in 1980s, and its 40-year development course proves that mobile communication is the result of the development of science and technology. Taking semiconductors as an example, every step of the development of mobile communication is inseparable from semiconductors. With the development of semiconductors, the shape of mobile phones is getting smaller and smaller, and the functions are becoming more and more diverse. Therefore, mobile communication itself is the result of technological development. The development of mobile communication promotes the development of science and technology. Due to the needs of mobile and communication, semiconductors are getting smaller and cheaper, and the price is lower.
In fact, many semiconductor companies now apply their advanced semiconductor chips to mobile phones. From 28 nm, 14 nm, 12 nm, 10 nm, 7 nm to 5 nm, the first user is a mobile phone, so the development of mobile communication promotes the development of semiconductors and even all walks of life. It can be expected that the further development of mobile communication will further promote the development of the whole science and technology. Mobile communication relies on the development of science and technology to promote scientific and technological progress.
Science and technology are the primary productive forces. Looking at the development of China's mobile communication technology, 1G is blank, 2G follows, 3G breaks through, 4G is parallel, 5G leads, and a great breakthrough in this field has been successfully achieved. The next step is to firmly grasp the commanding heights of science and technology and continue to climb the peak of science and technology.
Although 5G is still in the construction stage, the industry is already considering the construction of 6G. Now science and technology have formed a law of development, which will be updated every few decades. Compared with other countries, China has participated in a lot of standard-setting work in the field of 5G, and gained great initiative. For 6G related technologies, China operators, manufacturers and enterprises should also actively develop, seize the commanding heights of science and technology, and promote the future development of the new generation of mobile communications.
