Last month, the Ministry of industry and information technology and the national development and Reform Commission jointly put forward the goal of "by 2020, the scale of information consumption will reach 6 trillion yuan, with an average annual growth of more than 11%", of which 5g commercial will become an important contribution. So when can I use 5g mobile phone? China's civil 5g network market time to understand.
As the fifth generation mobile communication technology, 5g network brings people the first feeling is "fast"! Compared with 4G, the peak speed of 5g increases by 10 times, from 4g100mb / s to tens of GB / s. In other words, more than 10 high-definition movies can be downloaded in one second, and the number of user connections that can be supported has increased to 1 million users per square kilometer, 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. In 4G network, the delay from terminal to base station is generally 5 ms, and the delay from terminal to server is 50 ~ 100 ms. In 5g network, the delay from terminal to base station can be reduced to 1ms, and that from terminal to server can be reduced to 10ms. In the field of medical treatment, telemedicine not only needs to rent large capacity network lines, but also leads to surgical deviation due to network delay in the process of surgery. 5g technology makes up for the defects of the existing telemedicine network, the network speed delay is almost zero, greatly improving the success rate of surgery.
It is precisely because of these unique advantages that 5g will be further applied to industry, medical treatment, safety and other fields, 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, Internet of things and other related industries to realize the real interconnection of everything.
Although it is still a year and a half before 5g is officially put into commercial use, now the three major operators have been able to capture 5g. Among them, the Telecom said earlier that it would take the construction of 5g innovation demonstration network as an opportunity to realize 5g trial commercial use in 2019 and large-scale commercial use in key cities in 2020.
In the field of Internet of vehicles, 5g's ultra reliable and low 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 needs 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 autonomous driving in the true sense needs the support of network technology progress, and 5g can provide these capabilities. In the past decade, although the thunder of automatic driving and Internet of vehicles has been quite loud, the rain has been very small, because there are still bottlenecks in the basic technology, and the commercial use of 5g network is bound to provide a more suitable opportunity for the integration of automatic driving and Internet of vehicles.
Now, 5g technology development has entered a critical period, global communication operators are accelerating 5g technology verification and commercial application. 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 launch commercial 5g band from 2018 to 2020.
In the era of 3G and 4G, we are many years behind the developed countries in terms of license issuance. Moreover, in terms of 3G and 4G standards, we are still latecomers. If we have made a breakthrough in 3G, then 4G is running parallel and catching up with foreign developed countries. However, the license issue of 5g will not be later than that of developed countries. "Wu Hequan, academician of the Chinese Academy of engineering, said.
For the public and all walks of life, 5g is not only the next generation of mobile communication technology, but also a new network, connecting cars and cities, hospitals and families, people and surrounding things in a more meaningful way. Are you looking forward to it?
