How did China go from "blank in 1G, following in 2G, breaking through in 3G, and running concurrently in 4G" to "leading in 5G"?

Currently, our country has become a veritable Internet power, with the largest number of Internet users and the richest mobile network applications in the world. Looking back at the 30-year development history of my country's mobile communications, we can see a clear "catch-up trend": In the 2G era, almost all core technologies and standards were in the hands of foreign manufacturers;

In the 3G era, my country's Launched the independently developed standard TD-SCDMA, achieving a breakthrough from "coreless" to "core-based" and listed as one of the international standards. But it has to be admitted that there is still a big gap between this technology and the international mainstream. Because of this, in the 4G era, China Mobile is full of energy and vows to "run parallel with the world." Faced with fierce competition in the international market, China Mobile has chosen a TDD (time division duplex technology) path that is different from European standards. "We We are optimistic about the future prospects of TDD, and also trust the team’s indomitable innovative spirit and strong technological innovation capabilities. " Wang Xiaoyun, general manager of the technology department of China Mobile Communications Group Corporation, said. The reporter saw in the China Mobile Innovation Building that the patent wall in front of him was densely covered with various certificates. The staff told reporters that these are far from all the company's "achievements" "Individual". For TDD alone,

China Mobile has obtained about 1,500 technology patents. Through independent innovation, the "Chinese Legion" fought collectively and played multiple rounds of games, successfully overcoming the discourse of Chinese enterprises in the standardization system. Due to difficulties such as insufficient rights, TD-LTE has won the competition among multiple TDD technology proposals around the world and has become one of the two mainstream 4G standards in the world. At present, my country has built the world's largest 4G premium network, and China Mobile is also in the process of construction. It has set many records: the shortest time, completing 10 years of construction work in the 2G era in less than 3 years; the largest scale, with 1.62 million 4G base stations built for the first time, accounting for 30% of the global 4G network scale, with a cumulative investment of 450 billion Yuan, 4G users reached 583 million. More importantly, my country's TD-LTE has successfully gone abroad and is widely used in the global market. China Mobile's success in 4G network construction has led the research and development of 5G technology. 5G technology, standards, industry, commercialization and internationalization have laid a solid foundation. The arrival of 5G means that we will usher in an era of interconnection of everything," said Yang Guang, deputy director of the Wireless Technology Research Institute of China Mobile Research Institute. For example, "If 4G is compared to 'building roads,' 5G is 'building cities.' 5G will bring an immersive experience anytime, anywhere, and safe and reliable autonomous driving will become a reality." China Mobile officially launched 5G research and development work in 2012. Over the past five years, the company has made positive progress in strategic research, technological innovation and standardization, industrial promotion, joint innovation, and participation in national projects. In terms of technological innovation, China Mobile has formed a complete set of 5G technology systems, which effectively complements the new multi-access, ultra-dense networking, full-duplex and other technologies proposed by other domestic companies, and together form China's 5G technology reserve.
