5G and Its Implication to Communication in China

Abstract

Mobile communication basically has a generation of ten years. The first few years before each generation starts are a mature process, and there are many version upgrades during each generation. It can be said that the technology is constantly improving. It is obvious that the technology is not mature when it is just commercial, especially 5G. Development time axis of world mobile communication technology standards. The completion of 2G international standard was completed in 1987, and commercial use was in 1991. There was nearly four years in between. For 3G, 3GPP standard was completed in 1999, ITU was in 2000, and the earliest commercial application was in 2001. There was also more than a year or even two years. The completion of 4G standard and the earliest commercial use of 4G were 2009 and 2010, respectively, with an interval of one year. However, 5G commercial almost keeps pace with international standards. Therefore, in this sense, we can say that 5G is not mature enough, which is also true in foreign countries. In terms of the development of China’s mobile communication, 1G is six years later than the international first commercial, 2G is three years later, 3G is six years later, 4G is three years later, 5G is synchronous. Therefore, it can be said that in the past few generations, the developed countries began to use commercial products several years later and basically used foreign products. To 3G, China began to have some domestic brands, and 4G has been greatly improved. By 4G, there is less risk of trial and error in China, because others are ahead. However, due to the later commercialization in developed countries, China has not only paid the market price but also has to bear the increased product cost due to the lag of its own patent; thus, the industrial chain has lost the opportunity to lead. The chapter will address: (1) what is the policy position of the 5G of COVID-19 in China’s scientific and technological innovation, (2) how is it developed, (3) how does it drive China’s economy out of the post COVID-19 era and (4) promote China’s economic development? These series of questions would be the key topic of concern to the future world.
