The 5G era is approaching! A number of technical indicators, China leads the world, the network speed becomes faster, and there are many surprises

　　Cctv news"2017 China International Information and Communication Exhibition" is being held in Beijing. The test results of the second phase of 5G released by the China 5G Promotion Group, which is composed of the Ministry of Industry and Information Technology, the National Development and Reform Commission and the Ministry of Science and Technology, show that all indicators meet the standards of the International Telecommunication Union, and 5G is expected to be commercialized in 2020!

　　The second phase of 5G testing leads the world in many indicators.

　　According to experts, compared with 4G, the peak rate of 5G can reach 20Gbps, and the number of links per square kilometer can exceed 1 million. According to China’s 5G Promotion Group, the test shows that the existing 5G key technologies and scheme designs can fully meet the performance requirements of 5G networks such as peak rate, delay, bandwidth flow and access density determined by the International Telecommunication Union, and some key indicators have reached the world leading level.

　　Tong Wen, Chief Scientist of Huawei Wireless:

　　In the second phase of the test in 5G countries, we have set new records in many industries, among which the downlink rate is 32 gigabits per second, the requirement of the International Telecommunication Union is 10 gigabits per second, the delay time is 1 millisecond, and we achieved 0.33 milliseconds.

　　In the second phase test of 5G organized by China this year, the performance of some China enterprises almost reached the best level in the industry. A number of key technologies submitted by Huawei have been adopted as the international core standards of 5G, China Telecom is the lead and main contributor to the research of many key technologies of 5G, and ZTE has become the only manufacturer to provide a full range of equipment to participate in the seven scenarios of the second phase of China 5G test … … This means that communication enterprises in China are expected to lead the world in the 5G era.

　　5G has preliminary pre-commercial conditions.

　　At present, domestic enterprises have initially met the pre-commercial conditions in technology, system and terminal equipment. Next year, after the first-stage standard of 5G is determined, all links in the 5G industrial chain can quickly realize large-scale industrialization development.

　　According to the plan of the Ministry of Industry and Information Technology, China’s 5G experiment will be divided into two steps:

　　The first step is to develop experiments for 5G technology from 2016 to the end of 2018. The main goal is to participate in supporting the formulation of 5G international standards;

　　The second step is to develop experiments for 5G products from 2018 to the end of 2020, with the main goal of conducting 5G pre-commercial testing.

　　Among them, the first step is divided into three stages: 5G key technology test, 5G technical scheme verification and 5G system verification, and then it will enter the stage of 5G network construction, and it is expected to be officially commercialized as early as 2020. But this doesn’t mean that 4G will quit the historical stage in 2020. Experts believe that 3G and 4G have coexisted for a long time, and the coexistence period of 5G and 4G will be much longer than that of 3G and 4G.

　　The White Paper on the Economic and Social Impact of 5G released by China Information and Communication Research Institute this year predicts that 2019 will become the first year of China’s 5G commercialization; In the initial stage of 5G commercialization, operators will carry out network construction on a large scale. By 2020, the investment in network and terminal equipment may be as high as 450 billion yuan; By 2030, 5G will drive China’s direct economic output to 6.3 trillion yuan, and the total output will be 10.6 trillion yuan in terms of indirect contribution.

　　5G lays the foundation for the Internet of Everything

　　At the communication exhibition, remote driving and holographic images based on 5G attracted many viewers to participate in the experience. When you put on special glasses, you can see another person sitting in the chair beside you so clearly, just like the scene in the movie Star Wars.

　　"In the future, autonomous driving will reach a speed of more than 120 kilometers per hour in a few milliseconds, and 5G can complete the intelligent response of autonomous driving within a delay of 1 millisecond." The staff introduced.

　　John young, president of Zhongcheng Think Tank, said that the speed and access capability of 5G can meet the needs of smart terminals such as automobiles, drones and robots in the future, and it is an important foundation for the future Internet of Everything. Many experts in the industry believe that 5G will be the first to be applied in the field of people’s livelihood, because there are more terminals and a wider range in the field of people’s livelihood.

　　"In the 5G era, large-scale applications such as smart meter reading can be better realized. Because the number of links in 4G base stations is far less than 5G, in the future Internet of Everything era, it is necessary to rely on 5G to achieve billions or even tens of billions of links. " John young said that in the future, a single 5G network can carry at least 1 million devices per square kilometer. The biggest highlight of 5G technology is that it can still meet the needs of future mobile services at a high speed in the case of limited spectrum resources. Therefore, the 5G network can provide brand-new technologies, and establish connections between people and things at a lower cost.
