The development of communication technology has never stopped. Since the launch of China's fourth-generation mobile communication (4G) license in December 2013 and the official launch of 4G technology, the world's research on fifth-generation mobile communication (5G) technology has begun. Knowing that at the Third World Internet Conference held in Wuzhen last November, the 5G technology prototype that Qualcomm can bring to achieve "Internet of Everything" was selected into 15 "black technologies", and the topic of 5G technology began to gradually increase.
Now that the two sessions are being held, it is worth noting that this government work report first mentioned the “fifth generation mobile communication technology (5G)â€. The whole test is carried out in two steps: the first step of the technical R&D test is completed from 2016 to 2018; the second step is to conduct product R&D tests from 2018 to 2020 to achieve the goal of commercial 5G in 2020.
According to industry insiders, this means that communications equipment manufacturers, terminal operators and operators who have already joined the 5G industry chain mean that the previous investment has been affirmed, which means that the prospects are more clear. At the same time, 5G technology is expected to be commercially available by 2020.
The 5G technical standard has not been released, but it has already fired in advance.
The fifth-generation mobile phone mobile communication standard (5G), also known as the fifth-generation mobile communication technology, is also an extension after 4G. It is under study and the network speed can reach 5M/S - 6M/S. On February 22 this year, Qualcomm and industry research company IHS Markit jointly released "5G Economy: How 5G Technology Will Influence the World". Qualcomm believes that by 2035, 5G will generate $12.3 trillion in economic output globally. This is almost equivalent to the total expenditure of all US consumers in 2016, and exceeds the total consumption expenditure of China, Japan, Germany, the United Kingdom and France in 2016.
Although in the industrial development, standards play a leading and promoting role, it can even be said that there is no industry prospect without industry standards. However, for 5G, although there is still a period of time before the release of the first technical standard in 2018, it has already shown a premature situation. For example, Korea Telecom (KT) has announced that it will complete its 5G network deployment by September 2017. Japanese operator NTT DoCoMo will also test 5G network in Tokyo this year. Recently, China Mobile, ZTE and Qualcomm also announced Cooperation and cooperation will be carried out in China in the second half of 2017.
For users, the most direct perception of 5G technology is the improvement of mobile bandwidth. For example, mobile terminals such as mobile phones can download at a speed of 1G to 10G per second, and a high-definition movie can be downloaded in a few seconds; video calls are everywhere; and high-speed networks can be enjoyed in densely populated areas. These are also the main efforts of people on 5G technology. It is understood that 5G will play an important role in the 2018 Korean Winter Olympics and the 2020 Summer Olympics in Japan. All major mobile operators plan to provide 5G services at that time, and 5G technology will play an important role in live broadcast.
The reason why the 5G technology field has emerged is because of the huge prospect of 5G technology. The industry view has always believed that 5G is a key technology in the Internet of Things era. Wang Jianzhou, president of China Association of Listed Companies and former chairman of China Mobile, once expressed this view on the current 5G trend. "The technology of 5G is very clear, but where is the application of 5G? Remember when 3G came out, People are also asking where the 3G application is. Until Steve Jobs launched the iPhone, everyone knows that 3G makes the phone into a computer. However, the depth, breadth and precision of 5G far exceeds 3G and 4G, relying on one person. The era of a company to change the world has passed. The uncertainty of 5G applications has brought endless opportunities for entrepreneurs."
China's communication standard evolution theory, gradually entered the accelerated run
China's role in the development of mobile communication standards has emerged as a trend of the past. The first and second generation mobile communication standards were developed by the United States and Europe respectively. However, in the formulation of the 3G standard, China has preemptively formulated TD-SCDMA. At that time, China began to accumulate a certain amount of technology and talents as well as the development of international standards. In the 4G era, China has become a different faction against Europe, and has developed a TD-LTE standard that is different from the European-led LTE-FDD, and has been recognized and promoted by multinational operators. In the 5G era, China clearly has the strength to compete with Europe and the United States in the development of 5G standards.
As early as February 2013, the Ministry of Industry and Information Technology, the National Development and Reform Commission, and the Ministry of Science and Technology jointly established the IMT-2020 (5G) promotion group, relying on major special projects to vigorously support 5G technology innovation, and fully launch the 5G technology research and development test. In addition to the government level, major companies are actively deploying 5G, such as China Mobile, Huawei, and ZTE, which have already achieved results in 5G technology.
Among the three major operators, the layout of China Mobile's 5G technology is one step ahead. At present, China Mobile has made breakthroughs in technology research and development, enterprise cooperation, and standards development. China Mobile has set a new timetable for the listing of 5G networks: launching 5G technology trials, standard customization and products in 2016. Development; in 2017 and 2018, the field trial will be launched separately, and the scale-oriented experiment will be carried out for commercialization; by 2020, China Mobile will complete the 5G scale commercialization according to the national plan. According to this timetable, China Mobile is in sync with developed countries such as South Korea, Japan and the United States.
Huawei's layout in 5G technology is also remarkable. For example, at the RAN1 (Wireless Physical Layer) #87 meeting of the 3GPP of the International Mobile Telecommunications Standardization Organization held in Reno, Nevada, last November, Huawei's Polar Code solution became The final scheme of 5G control channel eMBB scene coding. The industry believes that the Polar Code code, which is led by Huawei and promoted by China, has been adopted by 3GPP as the 5GeMBB control channel standard solution. It is an important progress in the research and standardization of 5G mobile communication technology in China.
ZTE also issued a notice at the just-concluded World Mobile Conference, claiming to launch the world's first mobile phone Gigabit Phone with a download speed of 1 Gbps per second, entering the threshold of 5G network.
Huawei Polar code was selected to help China seize 5G voice
From the perspective of the popularity of 4G, the popularity of 5G will be faster. Looking at the world, East Asia is leading the way in mobile 5G technology. The industry believes that this situation will occur because of the demand for high-speed connections from users in these specific regions, and 5G will also greatly help the future revenue growth of these regions.
It can be seen that the series of economic benefits brought by 5G technology can not be underestimated, which is why the Polar code scheme promoted by China last year became the final solution of the 5G control channel eMBB scene coding. The focus of people's discussion is on the 5G standard. Has been won by China.
Although the 5G standard was taken by China, some of them finally chose Polar code, which is a great affirmation of Huawei and even China's 5G technology.
In this regard, Huawei has given such a relatively pertinent comment: the decision of LDPC code and Polar code is a milestone of the 5G standard, further promotes the industrial process of 3GPP global 5G unified standard, and strengthens the telecom operators and equipment. The belief and determination of all parties in the business, chip and terminal manufacturers to work together.
As early as 2009, 4G technology has not yet entered commercial use, Huawei has already started research on related technologies. In the years of research on 5G technology, Huawei has accumulated many patents, such as Huawei’s core patents in the Polar standard. 70%. On the 5G road, Huawei has taken advantage of the first move. According to industry insiders, in the future, once commercial products and programs use related patents, Huawei can charge corresponding patent fees. Huawei, which is at the top of the industry chain, has the most profit and the largest voice.
This government work report mentions 5G for the first time. This China 5G test is also the first national 5G test led by the government and planned by the government. In any case, the prospect of China's 5G is more clear, and 5G technology has also entered the final stage, and manufacturers such as Huawei have already seized the opportunity.
