5G has been commercially used for 3 years. According to the data released by the Ministry of Industry and Information Technology recently, as of the end of September, the total number of 5G base stations in China had reached 2.22 million, a net increase of 795000 over the end of last year, accounting for 20.7% of the total number of mobile base stations, 6.4 percentage points higher than the end of last year. At the same time, the total number of 5G package users of China's three major operators has exceeded 1 billion; The number of 5G mobile phone users reached 510 million, a net increase of 155 million over the end of last year, accounting for 30.3% of mobile phone users. Over the past three years, China has adhered to the principle of moderately leading, steadily and orderly carried out 5G network construction, continued to improve the depth and breadth of network coverage, comprehensively promoted 5G commercial deployment and large-scale application, actively cultivated and strengthened new drivers of economic development, and constantly consolidated the digital base for high-quality economic and social development. To build the world's largest boutique network, China Mobile employees built a 5G base station on a 25 meter high communication tower on an island reef more than 70 kilometers from the Yellow Sea coast. "Download rate 280.48Mbps, upload rate 179.16Mbps!" After all the hardships, the farthest 5G base station in Jiangsu, with 120 km of submarine cables, was finally built, and the wireless network speed in the nearby sea area reached 10 times that of the 4G period. From cities to villages, from islands to Gobi, from mines to Mount Everest, climbing towers, installing antennas, laying optical cables... In the past three years of 5G commercial use, China's network builders have aimed at broader, deeper and more sophisticated goals, overcome difficulties, and created the world's largest 5G boutique network covering the country, with advanced technology and excellent quality. Zhao Gang, president of CIIC Industrial Research Institute, said that in the past three years of commercial use, China's 5G construction has maintained a leading level in the world. By the end of September, China's 5G base stations accounted for more than 60% of the total number of 5G base stations in the world. The world's largest 5G network has been built. The 5G network has covered all prefecture level cities, county towns and urban areas, and more than 92% of towns and townships in the country. 5G mobile phone users exceeded 510 million, making it the largest user group in the world. "Over the past three years, 5G has made good progress in network deployment, consumer business and industry applications. As of October, more than 230 operators around the world have launched 5G commercial services, deployed more than 3 million 5G sites, and reached 700 million 5G users. Based on the rapid progress of network deployment, 5G is leaping from a large-scale commercial period to a high-speed development period." Hu Houkun, Huawei's rotating chairman, said. 5G dividends are gradually released. Zhao Gang analyzed that the first is the dividend of network construction. The investment in the construction of 5G base stations and the production of smart terminals have driven the development of chip and electronic communication product manufacturing industries in the upstream of the 5G industry chain, as well as the consumption of mobile phones and applications in the middle and downstream of the 5G industry chain. Second, the dividend of 5G industry application. 5G+industry applications are the mainstream of 5G applications at present. Over the past three years, through the accumulation of more than 20000 5G industry application demonstration scenarios and cases, demonstration enterprises and users in various industries have fully enjoyed the new experience and value brought by 5G applications. The third is the dividend of business growth. Although the 5G network construction of operators is still in the investment period and the 5G business is still in the embryonic stage, the 5G network is a telecom operator
