Academicians of the Chinese Academy of Sciences and the Chinese Academy of Sciences hotly discussed 5g: it will drive the 15.2 trillion digital economy. On November 20, it can be seen from the schematic diagram that the 2019 world 5g conference will be held in Beijing. At the 2019 International Symposium on future information and communication technology held during the conference, many academicians from the Chinese Academy of Sciences and the Chinese Academy of Engineering expressed their views on 5g

from November 20 to 23, 2019 world 5g conference was held in Beijing. Photographed by Wu Tao, Zhongxin

liuyunjie, academician of the Chinese Academy of Engineering: 5g development faces three application scenarios

liuyunjie said that 5g development faces three application scenarios, one is AR and VR ultra-high definition video, including 4K and 8K, and the other is industrial interconnection and car service

4k, 8K and ar/ar standards are far from being met by the current interconnection, because the original design of the interconnection is to delay 90 milliseconds, while in 5g application scenarios, it may require a delay of milliseconds

for example, if a young man wants to hug a lover in a different place and can feel the heartbeat of the other person, the sensor will support the development of this scene

to produce products more in line with market demand, car couplets, whether millimeter wave or laser radar, must respond to instructions in a very short time. If this instruction is lost, cars may collide with each other or hit people. These are some technical problems to be solved. Liuyunjie said

Yu Shaohua, academician of the Chinese Academy of Engineering: 5g's iconic applications have three dimensions

Yu Shaohua said that 4G is mostly used by, Alipay, etc., including location-based services. Now everyone is concerned about the question: what are 5g's iconic new applications and devices

to sum up, there are three dimensions, namely, the three characteristics of 5g, which enhance mobile broadband, high reliability and low delay. Yu Shaohua said that for example, in terms of immersive virtual communities, social networking and games, there will be iconic applications and vr/ar virtual reality devices

there are also automatic control equipment and robots in vertical industries, and various sensors. Users can select products and equipment that are more suitable for themselves. For example, remote feeding and grazing are applications supported by various biosensors

8K UHD video, UHD video terminal and camera are also available. This is a relatively new type. It is a carrier and is gradually moving towards AI video monitoring

Yu Shaohua said that in the 5 S- ε The curve is also called rheological hardening curve or hardening curve. Hollomon formula s = k ε N is the simplest fitting expression of this curve. In the later stage of G, there may be immersive experiences, including industrial interconnection, new media applications, mature AI services, AI perception, land, sea and air integrated communication, and of course, a number of space communication devices

Yin Hao, academician of the Chinese Academy of Sciences: 5g has brought about a digital economy of 100 billion level

Yin Hao said that the Chinese Academy of information technology has made a calculation that 5g will drive China's economic growth by 15.2 trillion yuan from 2021 to 2025

this figure consists of two parts. First of all, the three major operators plus radio and television will build 5g networks, with an investment of 3.3 trillion yuan. Yinhao said

Yin Hao said that these investments have solved a lot of employment, driven the development of digital economy in various industries, and the industrial added value reached 11.9 trillion yuan. The sum of the two amounts to 15.2 trillion yuan

Yin Hao said that 5g will become a new key infrastructure for the development of digital economy to meet the construction needs of the new generation of networks and form a main body of the next generation of key technologies in the world
