The 5th Generation Mobile Communication Technology (5G for short) is a new generation of broadband mobile communication technology featuring high speed, low latency and large connection, and is the network infrastructure for realizing the interconnection of human, machine and things. The International Telecommunication Union (ITU) defines three major application scenarios for 5G, namely enhanced mobile broadband (eMBB), ultra-reliable and low-latency communication (uRLLC), and massive machine type communication (mMTC). Enhanced Mobile Broadband (eMBB) is mainly for the explosive growth of mobile Internet traffic, providing mobile Internet users with a more extreme application experience; ultra-reliable and low-latency communication (uRLLC) is mainly for industrial control, telemedicine, and autonomous driving. The application requirements of vertical industries with extremely high requirements for reliability and reliability; Massive Machine Type Communication (mMTC) is mainly oriented to the application requirements of sensing and data acquisition such as smart cities, smart homes, and environmental monitoring. In order to meet the needs of diverse application scenarios of 5G, the key performance indicators of 5G are more diversified. The ITU defines eight key performance indicators of 5G, among which high speed, low latency, and large connections have become the most prominent features of 5G. The user experience rate reaches 1Gbps, the latency is as low as 1ms, and the user connection capability reaches 1 million connections/square kilometer.
With the rapid development of scientific research and technology in my country, it has entered the era of 5g, and many industries are integrating with it. Recently, Jiangsu is developing rapidly, which has injected new momentum into the high-quality development of Jiangsu. Rapid development of 5g technology If any technology cannot be implemented or scaled, it is no different from talking on paper. In recent years, Changzhou has made great efforts to build a high-quality industrial star city and strive to promote high-quality development to be at the forefront of the whole province. Jiangsu Mobile has taken the lead. Exceeded the 20215g construction target proposed by the Ministry of Industry and Information Technology. It is estimated that by the end of 2020, the number of 5g base stations in China is expected to reach 650,000, achieving continuous outdoor 5g coverage in all prefecture-level cities across the country, key coverage in counties and places, and indoor coverage in key scenarios. Jiangsu Mobile 5g It has achieved full coverage of urban sections of the province’s subway lines, and achieved contiguous coverage of hotspots in districts, cities, and counties across the province, and deployed 5g networks in window scenarios such as high-speed railways, subways, expressways, airports, scenic spots, and bus stations across the province. , At present, a total of 715,000 5g base stations have been built in China. The number of 5g users nationwide has exceeded 66 million in the first half of last year. Jiangsu Mobile has also researched low-cost solutions to help the development of 5g vertical industries. In terms of 5g development, it has always been the first to try, and it is at the forefront of the country and even the world.
Realizing the digital upgrade of industries 5G has the advantages of high speed, high efficiency, and low latency. It can be used to make great efforts in the industrial field. The most typical application scenario is intelligent manufacturing. This conference aims to deepen the Guangdong-Hong Kong-Macao Greater Bay Area. The cooperation between the digital economy and the industrial Internet will give full play to the effect of industrial agglomeration in the Greater Bay Area, accelerate the digital transformation and upgrading of industrial clusters empowered by the industrial Internet, and achieve high-quality development of the manufacturing industry. The first 5g base station in Jiangbei New Area was built in the CRRC Digital Technology Workshop. 5g network environment deployment and system launch will further promote the application of virtual reality and other technologies in the industrial field, accelerate the construction of smart workshops and smart factories, build the first practical case of 5g application in the industrial Internet field, and realize industrial digital upgrade. High-quality products and services, through the scale of production, reduce production costs and improve production efficiency, so as to maximize the efficiency of the industrial chain and act as a labor-intensive enterprise.
At present, China’s mobile communication technology is leading. Now my country is under the guidance of 5g technology and has entered the era of big data. Only by keeping up with the pace of the times can we not be eliminated. Therefore, many industries are now completing digital transformation. The laboratory is in the key technology of 5g. In-depth and systematic research has been carried out, and important innovative achievements have been formed in large-scale mimo technology, channel encoding and decoding technology, network intelligence technology, etc., and some achievements have been commercialized in cooperation with enterprises; 5g experimental system has been constructed, and ultra-large-scale The key transmission technology of mimo is verified in typical actual scenarios. “GAN RF PA is an inevitable choice for 5G base stations in the millimeter wave band, and is expected to become the mainstream direction of base station PA. This experimental system enables my country to maintain a first-mover advantage in the field of mobile communication technology.
In the recent period, with the outbreak of the epidemic around the world, all the people on earth seem to be living with a nerve. But there is a lot of news about the construction of 5G, not from scientists or user experience, but from conspiracy theories of some Western people. They believe that 5G is the way the epidemic spreads, and the reason why the new crown epidemic can spread on a large scale around the world is because of the construction of 5G signals. Although this sounds very funny, what is even more amazing is that not only people in the West believe it, but also many people believe it. In order to do so, they not only organized demonstrations to protest, but also frantically smashed the 5G signal base stations that had been built.
Although we cannot understand the behavior of the Western masses, we can see that China is accelerating the construction of 5G base stations. The three major domestic network operators have also begun to announce their respective operation plans, hoping that China will enter the 5G era as soon as possible. As early as last year, some regions have already started trial operation of 5G signals. Some users who experienced 5G signals in advance said that compared with 4G signals, 5G signals not only have faster network speeds, but also have very low network latency and more stable signals. However, there are also a small number of people who believe that compared with 4G, the speed improvement is not as obvious as legend, and the construction cost of 5G is higher and more expensive. Why should China spend this unjust money?
As with the development of communication technology in the past, compared with the direct value created by the communication technology itself, the industry upgrading led by the upgrading of communication technology generates more considerable profits. In the earliest days, people communicated through the use of pagers. When the communication technology enters 2G, people can communicate through a large amount of text. With the development of the 3G era, we can get rid of dry and boring text and send more colorful pictures. The arrival of the 4G era has brought us into an era of video. One of the most rapidly discovered industries is the video production industry. The video platform represented by Station B has brought new opportunities to many ordinary people.
In recent years, Chinese technology companies have gradually emerged in the global market, and Huawei is one of them. Huawei’s 5G patent reserve ranks first in the world, and it is also due to Huawei’s technological advantages that China has become the country with the largest number of 5G standard patents.
Recently, at the Symposium on Solid Promotion of 5G Development held by the Ministry of Industry and Information Technology, my country proposed to build a high-quality 5G network and fully release the huge potential of 5G to expand the new momentum of economic development. The person in charge of the Ministry of Industry and Information Technology said that my country has built the world’s largest 5G network, built more than 700,000 5G base stations in total, and promoted the co-construction and sharing of 330,000 5G base stations. 5G has entered a critical stage of integration and innovation. The “White Paper on China’s 5G Development and Economic and Social Impact (2020)” issued by the China Academy of Information and Communications Technology pointed out that the potential of 5G’s impact on the economy and society has begun to appear. Yuan. In 2021, my country’s 5G technology and related industries will achieve high-quality development based on the principle of making progress while maintaining stability.
As the development of 5G technology becomes more mature and its applications become more and more extensive, consumers are eager to try it at the beginning, and now enjoy the efficiency and convenience brought by 5G products. Relying on the technical architecture of “device-edge-cloud-network-intelligence”, Lenovo has taken the lead in realizing the application of 5G in the three major fields of smart manufacturing, smart city and smart transportation. Thanks to Lenovo’s 5G private network solution, Lenovo’s Wuhan manufacturing base has the industry’s first 5G + IoT automated assembly line, setting an industry benchmark for efficient and flexible manufacturing. With the blessing of Lenovo 5G, 5G unmanned road sweepers, 5G law enforcement vehicles and 5G unmanned patrol vehicles appeared in the ancient city of Lijiang, putting a smart label on the ancient city and giving it a new look.
