The white-hot competition of 5G technology is no longer a secret.On the other hand, Huawei officially released the world's first 5G commercial chip and terminal at the pre-communication conference of World Mobile Communications held in Barcelona and announced that it will launch 5G industrial module and car box.
What exactly is the international status of China's 5G technology and its applications? Will it really push the United States to halt its promotion by banning sales?
The technology game has become the norm
5G technology research and development in the global scope has been the focus of competition for various manufacturers.
As early as 2009, various telecom equipment manufacturers and operators began to research and develop 5G technology. Up to now, 5G technology competition has entered a 'white-hot' phase. Operators such as AT & T in the United States, Japan NTT, China Telecom, etc. Also strive to become the first company to provide 5G services.
So, Huawei was banned this time, whether the 5G strategic deployment of the United States?
For this issue, Zhou Zhigang, a researcher at the Shanghai Institute of Microsystem, said in an interview with the "China Science News" that "Huawei was banned from selling goods and reflected the technical and commercial conflicts." Such competition has been going on for a long time, Not something that's only available in the 5G era. "
'5G as a global technical standards and norms, manufacturers of equipment and terminals based on such standards is certainly hope to be sold globally, Huawei for the global market, certainly do not want to just China, Europe, North America, the three major markets, certainly want to have Larger range. "Zhou Zhigang said.
Wang Huiming, professor of Xi'an Jiaotong University's Department of Information and Communication Engineering, also said that as a part of the future infrastructure of information society, communication technology is a norm and should be confronted with a mature attitude.
Change is not just communication
Communication technology has gone from 'big brother' in the era of 1G to 'phone message' in the 2G era to 'video phone' in the 3G era to 'mobile Internet' in the 4G era With the increasing demand for interoperability, 5G Times are coming to people.
Zhou Zhigang said that 5G technology will definitely improve its transmission rate and network latency. '5G's network architecture will be more flexible than ever and support complex groups of multi-service, multi-standard and multi-site configurations Network, some core network user plane function sink to the base station, reduce delay, speed will be faster.
Security certification is also a major highlight of 5G technology, 5G uses high-frequency technology to support large-capacity directional transmission, 'so that it will not be disturbed, it will not affect others, directional, confidentiality will be better, access to the base station The number of users will be more. "Zhou Zhigang said.
Before the 2G, 3G, 4G communications technology to pave the way for the popularity of 5G technology means more far-reaching change, this change is not only a technical level, but also the social structure level.
Recalling the short 3G era, Wang Huiming always sighs that "the market changes are hard to predict." When it comes to the 5G era, she saw a clear development main line: '5G is not just a communication problem, it will become A more basic infrastructure in the information society extends to every corner of life. '
5G higher transmission rate and greater traffic will 'stimulate a lot of new things.' In Wang Huiming view, 5G enhanced mobile broadband, will provide the audience with AR / VR games and smooth video experience; its low Delay high reliability features, will be conducive to the development of smart medical, intelligent driving; its large-scale giant connection features, it is possible for the popularity of things and smart home.
Large-scale commercial still need time
The formation of standards is the first step in commercial applications, and the 5G standard is being shaped by the global push.
In December 2017, the International Mobile Normalization Organization 3GPP released the first 5G NR (new air interface) standard. In June 2018, 3GPP will launch the first version of the 5G international standard, which means that 5G standardization will continue to take an important step forward.
In November 2016, 3GPP identified a 5G enhanced channel coding scheme for Mobile Broadband (eMMB) scenarios. The Polar Code was chosen as the control channel coding scheme. This scheme was led by Huawei as the core representative. That this means that Chinese manufacturers in the 5G standard formulation of the discourse gradually increased.
Wang Huiming said that in the 4G era, the guidance and support of relevant state departments, combined with the technological strength accumulated by enterprises such as ZTE and Huawei, have made China occupy an increasingly important position in the formulation of 5G standards.
However, 'would like to take the lead in occupying 5G high technology research and development, in fact, is to test the technological capabilities of equipment manufacturers. 5G standard system is very large, the polarization code is only a small part.' Zhou Zhigang said Huawei, ZTE as the representative Of the "Chinese power", if you want to become a "leader" still need to continue to accumulate.
The game is white-hot with a bright future, but the future of 5G may not be as fast as expected.
Turning to the final landing 5G standard, Zhou Zhigang said: 'Now that the 5G standard is only a preliminary standard, the final landing will certainly be completed within a year or two. Prior to manufacturers out of commercial interests and publicity considerations, will Do some experiments and demonstrations.
Wang Huiming that 5G technology development and user needs both promote each other, '5G's technical elements should be added in turn, the standard formulation is gradually evolving.And 5G large-scale commercial, the need to wait until the technology deployment and the market After the dual maturity of heat '.
