On November 21, the Ministry of Industry and Information Technology and other departments formally issued the “Notice of the 16th Branch on Printing and Distributing the Role of Private Investment in Advancing the Strategy for the Implementation of a Strong Manufacturing Strategyâ€, which revealed that private capital is encouraged to enter the telecommunications industry, and further speeding up and fee reduction is required. In the same month, the National Development and Reform Commission issued the "Notice of the General Office of the National Development and Reform Commission on Organizing and Implementing the Next-Generation Information Infrastructure Construction Project in 2018," stating clearly that next year, 5G network construction will be carried out in at least five cities. By then, the network planning field will usher in the first wave of dividends in communications.
What is the level of China's 5G technology? Why should the 5G market be included in the private "player"? Will the status of the three major operators be shaken?
The personage inside course of study tells, previous 3G has 3 kinds of systems, 4G has two kinds of systems, and as 5G of next generation wireless communication technology, will realize the unification of the standard in spectrum, network, terminal, application and so on truly.
"In order to achieve greater network bandwidth, these discrete spectrum divisions in the past were not enough, they needed to be optimized and integrated, and they were extended to new frequencies. This was to support greater bandwidth and the overall cost was lower. "The above industry sources told reporters.
According to industry insiders, the biggest difference between 5G and previous wireless communication technologies is the object of service. “The previous service was mainly people, and 5G will truly realize the interconnection of all things. Industry 4.0, smart manufacturing, medical and other industries will operate with the maturity of 5G technology and further promote the development of these industries. It can be said that what 5G has to bear is to change the whole Social and industry missions."
The reporter was informed that the three major domestic operators have invested over 300 billion yuan in the 4G field and are still in the cost recovery cycle. In this case, what are the reasons for brewing and building 5G?
Shen Gang, deputy general manager of the Corporate Development Department of China Telecom Shanghai, told reporters that because China is rapidly entering the smart society, applications such as industrial Internet, artificial intelligence, and AR/VR are rapidly gaining popularity. Their large-scale applications require a new generation of networks to carry 4G has no problem in watching videos on the move, and 5G focuses on solving the problems of high density and low delay connections between objects and objects, objects, and the surrounding environment. For example, when building an autonomous driving city, you need to rely on 5G networks. Realize the seamless connection and interaction between vehicles, signal lights, road induction coils, and intelligent control platform, and the delay needs to be in the millisecond level.
According to industry insiders, the most important 3G scenarios for 5G are large bandwidth, interconnected Internet of Things, and low latency. The low network latency and bandwidth are the biggest killers of 5G, which can increase the latency of 10 millisecond 4G networks to 1 millisecond at 5G. Although it is difficult to feel the above-mentioned network delay gap in downloading files, playing games, etc., the gap is “fatal†in terms of driverlessness (requiring millisecond-level interactive operation response).
Take the trial of Google’s self-driving car as an example. It needs to collect 1G of data in one second. Currently, Google’s self-driving car is a stand-alone version, which is processed by the vehicle on this machine. The car that will be mass-produced in the future may be a networked version. After the data is collected on the platform and then processed by the platform, the time delay is very high. Even if the delay is 0.1 second, the car will go out for a long distance and may cause accidents. The low latency of 5G is It is very necessary.
"In the era of the Internet of Things, a family will often have more than 100 things that need to be connected to the network, so a new system that requires a new generation of networks to be more efficient in overall spectrum utilization and connect more terminals. However, I expect 4G and 5G in the future. Will coexist, not 5G to 4G will be completely eliminated." Shen Gang said in an interview with reporters.
After entering the Internet of Things era, the demand for IP addresses will increase dramatically, and IPv6 will accelerate commercial use at the right time. Shen Gang introduced that at present, China is accelerating the deployment of IPv6 and will build the world's largest commercial network in 5 to 10 years. It is expected that by the end of 2025, China's IPv6 network size, user size, and traffic scale will rank first in the world. Networks, applications, and terminals will fully support IPv6, and will fully complete the smooth evolution and upgrade of next-generation Internet to form the world's leading next-generation Internet. Technology industry system.
5G Businessmen Prompt, China is Expected to Lead GloballyThe reporter was informed that 5G's large-bandwidth scenario will take the lead in commercialization. South Korea has plans to provide 5G technical services next winter Olympic Games. South Korea’s Samsung also announced with British operators last month that it is building a 5G network and Samsung will provide base stations and equipment.
Compared with foreign countries, China seems to be more mature in the 5G layout. In 2009, China had already carried out 5G research and demonstrated the 5G prototype base station in the following years.
On November 6, 2013, Huawei announced that it will invest 600 million U.S. dollars by 2018 to research and innovate 5G technologies and predict that users will enjoy 5G mobile networks by 2020; the first session will be held on May 31, 2016. The Global 5G Conference was held in Beijing and China began to move toward the core status of 5G. On November 17, 2016, the 3GPP (3rd Generation Partnership Project, similar to the International Communications Standardization Organization) held the 87th meeting to discuss the 5G short code solution. Ultimately, Huawei’s plan won and China’s plan was selected for the 5G standard.
From the 2G era can only run behind others, to become one of the developers of the 5G standard, who mastered the core technology of 5G, whoever has the future.
According to Grace, the president of the Global System for Mobile Communications Association (GSMA), “The first countries in the world will formally apply 5G in 2020, and China will surely be one of them. In the field of mobile communications, China is not only a leading country but also an innovation. Driven countries."
At present, the Ministry of Industry and Information Technology has started the third phase of the 5G technology R&D experiment, focusing on R&D, verification and industry synergy of products on the eve of commercial use. It is expected that 5G commercial or near-commercial products will be introduced in June next year.
China's three major operators have also stated that they will take the first step of commercial trial of 5G in 2018 and strive to achieve commercialization of 5G in 2020.
A person in charge of a private communications company told reporters that China’s telecommunications construction is actually guided and promoted by the state. It is difficult for European countries and the United States to cover the infrastructure of base stations, towers, and optical cables as densely and deeply as China. "China has a 5G basis and policies support it. According to the attributes of 5G, the base station density construction will certainly be much higher than it is now. Although the ITU standard for 5G has not yet been frozen (it is still updating), it is not until mid-year next year. It only started, but now some localities and companies have already started basic preparations such as the reserve of 5G base stations and the reserve of cloud architecture."
People in the industry believe that China is likely to be the first to enter the era of 5G networks, and once again confirmed that China can fully achieve the plan to fully commercialize 5G networks by 2020. "Unlike the 3G or 4G era, we followed people and we led everyone in the 5G era."
Civil funding 5G layout, accurate positioning is the keyIn order to ensure a leading position in the 5G era, relevant government departments have strongly supported the policy. Late last year, 16 departments such as the Ministry of Industry and Information Technology issued a document encouraging private capital to enter the telecommunications industry. This is the most obvious example. Under the policy support, private capital began to gradually enter the 5G industry chain.
Recently, China’s new generation of ultra-high-speed wireless communications (EUHT) with its own independent intellectual property rights was introduced to Shanghai by the Guangdong private-owned Xin’an Computer System Chip Co., Ltd. (hereinafter referred to as the “Xinan Lineâ€). It is reported that Shanghai Hong Kong Tongchuang (Shanghai) Culture & Technology Co., Ltd. (hereinafter referred to as "Shanghai-Hong Kong Tongchuang") and New Coast Line have established joint ventures to further develop EUHT's core technologies and products.
According to reports, EUHT technology is the world's first example of a successful 5G technology that has been successfully tested and put into use. It is three to five years ahead of the ITU's 5G technology timetable. EUHT technology research and development lasted for 6 years and 3 rounds, and was listed as a major national special project. Its main feature is that it can support “three highs, three lows, and three fines†(high reliability, high capacity, and high speed) at an hourly speed of 360 kilometers. Low latency, low power consumption, low cost, precise positioning, precise calculation, and fine control). At the same time, the network itself integrates the sub-meter dynamic positioning function, positioning accuracy and response time are higher than the GPS and Beidou special algorithms. EUHT technology has passed application tests such as high-speed rail, subway, intelligent transportation, and intensive coverage. In 2016, EUHT began to provide high-speed rail, subway, smart highways, and rural broadband wireless coverage in Beijing, Guangdong Province, Jiangxi, and Fujian. Investment in industrial applications.
Currently, leading companies in the domestic industry such as Huawei and ZTE are also stepping up research and development of 5G technologies. Huawei's senior technicians told the reporter that the mere technological maturity does not mean that 5G has been fully prepared, because 5G construction is an ecological environment that requires everyone to play together. “Huawei is also talking about the application of 5G with the industry, because now every 5G application is aimed at the vertical industry, and the business model of these industries is not the same, such as the auto-driving car networking, combined with VR live broadcast requires large bandwidth, low Delay, drone delivery requires navigation, remote control, etc. In these applications, Huawei and many partners have tested many scenarios."
The above-mentioned Huawei technicians stated that the partners are also motivators. Huawei's many open labs will provide funds for these partners to allow them to test and match. All the goals are to mature the technology and mature the ecological business.
Private capital can enter multiple links in the 5G industry chain. “Taking VR sports events as an example, operators, stadiums, event organizers, live broadcasters, etc. can all join hands to do VR events. Citizens can choose one of them, such as stadium reconstruction, network protection, terminal content, etc. The policy is to support private enterprises and operators to talk about cooperation. For example, private enterprises can make secondary operations and services as wholesalers from wholesale telecommunications traffic, said Huawei's senior technical staff.
In the eyes of the aforementioned industry, the introduction of public funds can provide better services to more users, but it will not fundamentally change the communications industry. “The communications industry is heavy asset, investment is very large, cycle return is long, generally it takes 5 years or more to recover the cost. 5G industry chain is relatively long, there are many players in the ecosystem. The previous model is the operator to the equipment supplier. After buying equipment, building the network and pushing the business, users will use it directly, but in the era of 5G, any business or application has operators, service providers, equipment vendors, third-party partners (providing terminals, sensors, modules, Business platforms, etc.) The industry chain will be more abundant. Private capital can find its own role and position within it."
