Since the Ministry of industry and information technology and the national development and Reform Commission jointly issued the "three year action plan for expanding and upgrading information consumption (2018-2020)", the target of "by 2020, the scale of information consumption will reach 6 trillion yuan, with an average annual growth of more than 11%. 5g business will become an important contribution force. It is required to promote 5g scale networking construction and application demonstration project. When will domestic 5g be listed? Will 5g network be commercialized on a large scale this year?
As the fifth generation mobile communication technology, 5g network brings people the first feeling of "fast"! Compared with 4G, 5g peak speed increases by 10 times, from 4G 100MB / s to dozens of GB / s. In other words, more than 10 HD movies can be downloaded in one second, and the number of user connections that can be supported has increased to 1 million users / km2, which can better meet the massive access of scenes like the Internet of things.
However, this is only the most basic ability of 5g. The greater 'power' of 5g lies in its' low delay 'characteristics. In 4G network, the delay from terminal to base station is generally 5 ms, and that from terminal to server is 50 ~ 100 ms. In 5g network, the delay from terminal to base station can be reduced to 1 millisecond, and that from terminal to server can reach 10 millisecond. In the medical field, telemedicine not only needs to rent large capacity network lines, but also causes the operation deviation due to network delay in the operation process. 5g technology makes up for the defects of the existing telemedicine network, and the network speed delay is almost zero, which greatly improves the success rate of surgery.
Because of these unique advantages, 5g will be further applied to the fields of industry, medical treatment and safety, which can greatly promote the production efficiency in these fields and innovate new production methods. At the same time, 5g will also penetrate into the Internet of vehicles, the Internet of things and other related industries to realize the real interconnection of all things.
Although it is still a year and a half before 5g is officially put into commercial use, the three major operators have been able to capture 5g. Among them, the telecom side said earlier that it would take the construction of 5g innovation demonstration network as an opportunity to realize 5g trial commercial operation in 2019 and large-scale commercial operation in key cities by 2020.
In the field of Internet of vehicles, 5g's ultra reliability and low time delay features meet the needs of v2x and automatic driving. In recent years, the development of v2x technology is emerging, but the existing 4G communication technology can not fully meet the requirements of v2x, and it is difficult to achieve the "standard configuration" of automatic driving technology. The transformation from Internet connected vehicle to remote driving, vehicle formation and real unmanned automatic driving requires the support of network technology progress, and 5g can provide these capabilities. In the past decade, although there has been a lot of thunder about automatic driving and Internet of vehicles, the rain drops are very small, because there are still bottlenecks in basic technology. The commercial use of 5g network is bound to provide more suitable opportunities for the integration of automatic driving and Internet of vehicles.
Nowadays, the development of 5g technology has entered a critical period, and global communication operators are accelerating 5g technology verification and commercial use. According to GSA statistics, as of July 2018, 42 countries and regions around the world have planned or launched 5g band auction, and 67 operators plan to start commercial 5g from 2018 to 2020.
"In the era of 3G and 4G, we are many years behind developed countries in terms of licensing. Moreover, in terms of 3G and 4G standards, we are still latecomers. If we have made a breakthrough in 3G, then 4G is running in parallel, catching up with foreign developed countries. However, the issuance of 5g license will not be later than that of developed countries. Wu Hequan, an academician of the Chinese Academy of engineering, said.
For the public and all walks of life, 5g is not only the next generation mobile communication technology, but also a brand new network, which connects cars and cities, hospitals and families, people and everything around in a more meaningful way. Are you looking forward to it?
