The dual gigabit development has ushered in the window period. What impact will it bring to your and my lives after three years?

May 06, 2021

The development of communication technology is changing with each passing day. In just a few decades, we have stepped from the initial 1G era to the current 5G era of Internet of Everything. The "Gigabit" era has arrived, and terms such as "Dual Gigabit" are often in our ears. Sounds, then what is "dual gigabit"? To put it simply, the network represented by the 5G mobile network Gigabit and the optical bandwidth network Gigabit (Gigabit optical network) is called "dual Gigabit". The two are a fusion and complementary organic whole, which can provide fixed services to a single user. And mobile gigabit access capabilities, have common features such as ultra-large bandwidth, ultra-low delay, advanced and reliable.

Separately speaking, the gigabit optical network uses fixed optical fiber connections, which has the advantages of large transmission bandwidth and strong anti-interference, and is suitable for indoors and some complex environments. And 5G is more flexible, mobile, and has a large number of connections. The advantages of the two are mutually complementary, and they compete and complement each other. Together, they form the "two wheels" and "two wings" that support the development of my country's new infrastructure and help the digital economy and digital transformation. ". Therefore, increasing the development of dual gigabit is the top priority of the communication network industry. The 2021 "Government Work Report" clearly requires that the construction of 5G networks and gigabit optical networks be increased to enrich application scenarios. The Ministry of Industry and Information Technology also issued the "Dual Gigabit Network Coordinated Development Action Plan (2021-2023)" This series of actions means that in the next three years, dual gigabit development will usher in a window period.

In three years, what goals will dual gigabit achieve? The "Action Plan" points out that in three years, a "dual gigabit" network infrastructure covering urban areas and qualified townships will be basically completed, so that fixed and mobile networks will generally have "Gigabit-to-home" capabilities. Gigabit optical network and 5G users accelerate the development, and the user experience continues to improve. High-bandwidth applications such as augmented reality/virtual reality (AR/VR) and ultra-high-definition video are further integrated into production and life, and the Gigabit application model of typical industries has become a demonstration. The core technology research and development and industrial competitiveness of Gigabit optical network and 5G have maintained the international advanced level, and the modernization level of the industrial chain and supply chain has been steadily improved. "Dual Gigabit" network security assurance capabilities have been significantly enhanced.

Specifically, by the end of 2021, the Gigabit optical fiber network has the capacity to cover 200 million households, the scale of 10 Gigabit passive optical network (10G-PON) and above ports will exceed 5 million, and the number of Gigabit broadband users will exceed 10 million. . The 5G network has basically achieved coverage in areas above the county level and in some key towns and townships, and more than 600,000 5G base stations have been added. Build more than 20 gigabit cities.

By the end of 2023, the gigabit fiber network will have the capacity to cover 400 million households, and the number of gigabit broadband users will exceed 30 million. It is necessary to accelerate the advancement of terminal maturity, encourage terminal equipment companies to accelerate the research and development of 5G terminals, and improve the product performance of 5G terminals.

my country's dual gigabit development is rapid, industry integration applications continue to incubate

At present, my country's dual gigabit is developing rapidly. As of 2020, 70 provincial telecom operators in 29 provinces in my country have launched gigabit broadband commercial packages; my country`s gigabit subscribers reached 6.43 million, a net increase of 5.53 million from the end of the previous year. Telecom operators serve high-value broadband users and promote business development will promote the rapid growth of gigabit broadband users. In terms of 5G, my country has built the world's largest 5G commercial network. 718,000 5G base stations have been built, with an average of more than 20,000 new base stations opened every week. 5G has achieved network coverage in more than 300 cities across the country. At the same time, it is accelerating the realization of in-depth coverage extensions in key areas. It also has more than 200 million 5G connections; 5G mobile phone terminal shipments exceeded 163 million units.

Although the above data is still increasing, in the long run, the construction of dual gigabit needs to be continuously strengthened and accelerated. At present, there is no explosive growth in applications of dual gigabit networks. This is in line with the completeness and advancement of dual gigabit construction. Sex has a lot to do with it.

Wang Zhiqin, vice president of China Academy of Information and Communications Technology, said: "Gigabit optical network and 5G innovative business applications are global problems, especially for China, which is already in no man`s land, and there is no mature model and experience to learn from. It is a new exploration and challenge."

As 5G has higher performance requirements for core devices such as baseband chips and medium and high frequency devices, for my country, which has weak technology research and development and manufacturing capabilities in semiconductor manufacturing processes and high-end RF device materials, 5G will usher in a bright moment. It is undoubtedly a severe test.

Even so, my country has never stopped moving forward. More and more 5G application scenarios are incubating. With the continuous improvement of 5G networks, I believe that 5G applications will continue to spring up like mushrooms in the future, especially on the B-side. , 5G converged applications are accelerating, and they have shown their skills in medical, smart manufacturing, smart mining and other fields, allowing the industry to experience the convenience brought by 5G. The gigabit network is a good player in fixed networks, so it has a pivotal position in the field of smart homes.

Challenges and Solutions in the Development of Dual Gigabit Networks in my country

With the rapid development of dual gigabit, there are also many challenges for our country. In terms of technical support, technical solutions for the application of the Gigabit optical network industry are still being explored, and technical solutions such as 5G end-to-end slicing still need to be improved; in terms of industrial support, high-end chips, material manufacturing platforms, and instrumentation are heavily dependent on imports and competition The current price of 5G modules is higher, and the complexity of 10GPON network equipment and terminals is higher than that of GPON; in terms of model innovation, the core value of dual gigabit applications is still being explored and explored. At present, family gigabit access and 5G services It is not [rigid demand"; the industry`s willingness to pay is not strong, and the business model is not clear; in terms of policy environment improvement, there is a lack of cross-industry integration and application standards, and the ownership, use rights, and data of each entity under the innovative model (such as virtual private networks) The management rights of the company have not yet been clarified, and the regulatory policy has yet to be determined."

In addition, in the context of "dual gigabit" large bandwidth requirements, how to achieve the smooth evolution of the current network form to the future architecture, solve the decoupling of the central office and terminal equipment, and realize the intelligent control of the network and the rapid deployment of end-to-end services is a must Problems to think about and solve. Moreover, the operating system in the dual gigabit era is also facing all-round changes in key areas such as networks, terminals, users, and developers. Therefore, it is necessary to deepen the operating system to support "dual gigabit" applications.

The problem comes, and the rest is to solve the problem. In view of the above situation, it is necessary for the industry to build consensus and cooperate together to promote the rapid development of dual gigabit in our country. You can start from the following four aspects: First, continue to promote the research and development of dual-gigabit technology standards, continue to promote the research and application of dual-gigabit and key evolution technologies, and promote the continuous development of technologies and standards; second, accelerate the promotion of gigabit optical access networks and 5G Network construction and deployment. Continue to implement network transformation and upgrades, accelerate the construction of 10G PON and 5G SA networks; build "100 cities Gigabit", vigorously promote the comprehensive coverage of dual Gigabit networks; in accordance with dual Gigabit optical requirements, optimize all links of the network, strengthen network experience monitoring, and focus on Enhance users' [end-to-end" network experience; third, vigorously promote dual gigabit innovative applications and create a mature business model. Continue to carry out business innovation competitions and application demonstrations to promote the innovation and incubation of dual-gigabit network business models; fourth, in accordance with the law of technological evolution, dual-gigabit drives the coordinated development of the industrial chain. Promote the coordinated development and growth of industrial chains such as basic research, core chips, optical devices, fiber optic cables, 5G terminals and network equipment manufacturing, and optical network equipment.

I believe that as long as the industry unites and cooperates, everyone will work together to eliminate difficulties and usher in a day when challenges are turned into opportunities.

Dual gigabit development will give birth to new formats and bring new life

Liu Liehong, Vice Minister of the Ministry of Industry and Information Technology, said: "With the widespread application of'dual gigabit' networks, high-speed, convenient, and interconnected broadband networks and the new services and applications that will be spawned by this, they will give us production and Life brings more room for imagination."

This is not difficult to understand. From the time when mobile phones could only make calls and send text messages to now we can watch short videos on mobile phones, life can be said to have undergone earth-shaking changes, and dual gigabit is above this again. The upgrade of communication technology, waiting for the technology to mature, will surely bring huge innovations to our production and life.

From the perspective of economic and social development, dual gigabit technology will further stimulate effective investment, promote employment and entrepreneurship, stimulate information consumption, prosper the digital economy, accelerate the construction of a new development pattern, and provide new momentum for high-quality development.

From the perspective of industrial digital transformation, because the dual gigabit usage scenarios can be fixed and mobile, and the advantages complement each other, it will promote the digital development process of all walks of life and provide technical support for the transformation of the industry.

From the perspective of creating a smarter life, faster Internet speed upgrades can provide people with a more convenient and smarter life. For example, high-definition video and AR/VR holographic applications have enriched our lives, and online education and telemedicine have also made life more convenient.

From these three aspects, we can already feel the huge potential of dual gigabit. In the future, I believe that the surprises that dual gigabit will bring to us will be far more than that.

Based on everyone's ardent expectations for dual gigabit, on March 29, China Academy of Information and Communications Technology, together with the Broadband Development Alliance and China Ultra HD Video Industry Alliance, held the "Gigabit Optical Network Boosting New Growth in the Digital Economy" forum. At the forum, many industry leaders jointly conducted multi-angle discussions on advancing the development of my country's gigabit optical network, boosting the growth of the digital economy, and digital transformation of the economy and society.

Among them, Duan Xiaodong said: [China Mobile is the world`s largest wireless operator and the world`s largest home broadband network operator. It has made great contributions to China`s broadband network business. The gigabit intelligent optical network combines gigabit access and high Quality OTN is the cornerstone of the development of the "Data Intelligence Cloud Network". Next, China Mobile will respond to the government's call for "dual gigabit" construction, build a foundation with light, and empower the development of the real economy with information construction." As a communications industry field It is believed that China Mobile will do its best to promote the development of dual gigabit.
