Five Factors For The Rapid Development Of 5G

- Jun 08, 2020-

114 June 9 special feature (Jiang Junmu) The news of the first anniversary of the 5G commercial licensing is endless. "Good start, vigorous progress" has become the most commonly used keyword when summarizing the development of 5G, and these two words are used to describe fixed networks. F5G, which corresponds to 5G, is also extremely appropriate.


"Fixed network technology continues to evolve from generation to generation, and now the F5G era is coming." Ao Li, director of the Institute of Technology and Standards of the China Academy of Information and Communications Technology and deputy secretary-general of the China Broadband Development Alliance, pointed out at the Huawei Global Analyst Conference in 2020 that there are Five factors contribute to the rapid development of F5G in China.


Speaking from "Mount Everest": F5G is developing rapidly


Recently, "F5G on Mount Everest" has become a hot topic-China Mobile and Huawei have deployed the F5G Gigabit line to the Everest Base Camp at an altitude of 5,300 meters and the 6,500-meter forward camp for the first time under extremely harsh environmental conditions, helping the height of Mount Everest in 2020 The work related to measurement and media live broadcast made F5G break into the public's sight for a while.


So what is F5G? This starts with the development of fixed networks. After more than forty years of development, the fixed network has ushered in a new round of intergenerational alternation like mobile communications. According to Aoli, the first and second generations of fixed networks are based on copper wire technology. The first generation solves the problem of voice and dial-up Internet access, and the second generation solves the problem of low-speed bandwidth access below 10Mbit/s; The third generation transitioned from copper wire to FTTB, which solved the access problem of bandwidth below 100Mbit/s; the fourth generation based on FTTH technology, solved the access problem of bandwidth below 200Mbit/s through EPON/GPON; and F5G is the fifth On behalf of the fixed broadband network, it continues to evolve on the basis of FTTH, and provides users with universal gigabit bandwidth access through 10G PON technology.


He pointed out that, unlike the previous four eras, based on the distinctive characteristics of gigabit access bandwidth, microsecond delay, extensive optical network connection and high-quality user experience, the fixed network business field in the F5G era began to expand from 2H to 2B. Business scenarios gradually cover multiple fields such as enterprise parks, transportation, security, and industry, and will enable digital transformation of various industries together with 5G.


After the development of the past year, F5G has set off a boom in the industry, and F5G construction has become a consensus. On June 26, 2019, the China Broadband Development Alliance officially released the "White Paper on Gigabit Broadband Network Business Application Scenarios". The system summarizes the top 10 business application scenarios of the 10G PON Gigabit network and proposes market space for related business application scenarios. , Business model, network requirements. At the China Light Summit on October 31, the research group "Network Power Research" of the Institute of Industrial Economics of the Chinese Academy of Social Sciences elaborated the research results "F5G: Leveraging the New Momentum of the Chinese Economy-Report on the Socio-Economic Effects of the Gigabit Fixed Network," For the first time, it scientifically sorted out and clarified the irreplaceable strategic role of F5G in building economic growth momentum, driving economic efficiency, and supporting the improvement of people's well-being.


On February 25 this year, the European Telecommunications Standardization Institute (ETSI) held the "Fibre to Everywhere" F5G online press conference, announcing the establishment of the F5G Industry Standards Working Group (ISG F5G) to the world, dedicated to studying the intergenerational evolution and evolution of fixed broadband networks Long-term development. It is proposed to define the fifth-generation fixed network from three application scenarios, eFBB (Enhanced Fixed Broadband), FFC (Full-Fibre connection), GRE (Guaranteed Reliable Experience), to promote the move from fiber to the home to the optical unit. During the Huawei Global Analyst Conference on May 19th, ETSI, China Broadband Development Alliance, Portugal Telecom and Huawei jointly launched the F5G Industry Development Initiative, calling on the upstream and downstream links of the global fixed network industry to join the F5G industry organization to jointly promote industrial prosperity and embrace F5G era. On May 28, British telecommunications consulting company Analysys Mason released the "European All-Optical Position Document" at Forum Europe "Achieving an All-optical Gigabit Society" event, pointing out that all-optical access networks are "strategic infrastructure."


As of May this year, 34 companies or associations have joined ETSI's ISG F5G, and this number was 10 at the beginning of the establishment of the working group. In terms of business development, as of the first quarter of this year, China’s operators have started commercialization of Gigabit fixed access services in 29 provinces, and the user scale has reached nearly 2 million in February this year, and the growth rate is still accelerating , "Starting from the fire of stars gradually igniting the plain."


Regarding whether 5G will adversely affect the development of F5G, Ao Li said that from the explosive growth of both 4G and FTTH in the past few years, it can be seen that the two are not a substitute for each other, but a mutually beneficial relationship. From a technical point of view, mobile broadband provides flexible and extensive access, while fixed broadband focuses on network reliability and service stability, and there is no building shielding problem, so the two have their own advantages for different application scenarios. F5G compares Suitable for home and enterprise park/private line access.


He further pointed out that the development of fixed mobile converged services (FMC) and bundling of Gigabit and 5G services are also inevitable choices for operators' business competition: "Some data show that the fixed broadband off-grid rate is relatively low, and fixed network advantages operate Businesses can promote 5G business development through the integration package of “to protect mobile”. At the same time, the 2C market is relatively large, and mobile advantage operators can also protect and develop fixed broadband users through the “mobile to repair” method.”


Explain five factors in detail: boost my country's rapid development of F5G


my country has already established a leading position in the field of fixed broadband, and the industry once said that "FTTH development looks at China". In the era of F5G, this leading trend will continue. In his speech, Ao Li explained in detail the five factors that contributed to the rapid development of my country's F5G.


First of all, the leading broadband network development level laid the foundation for my country to enter the F5G era. In terms of network capabilities, FTTH covers most of the country's urban and rural households. All cities in the country have basically built "optical network cities". 10G PON networks are rapidly deployed to form the basis of F5G development networks. At the user level, there are data showing that the total number of broadband household users in China It has reached 456 million households, ranking first in the world. The penetration rate of fixed broadband households has reached 90%. At the same time, FTTH accounts for more than 90% of all broadband users, reaching 93%. In terms of network speed, according to China Broadband Development Alliance monitoring data, As of the first quarter of this year, the average broadband user access rate in China has exceeded 160 Mbit/s. "The next goal is to achieve 300-500 Mbit/s, and some users can reach 1 Gbit/s."


Second, industrial policies continue to be promoted. In August 2013, the country released the "Broadband China" strategy and implementation plan, and in recent years advocated speed and fee reductions, creating a good environment for the development of fixed networks. As for F5G, as early as May 2019, the Ministry of Industry and Information Technology clearly proposed to carry out "dual G dual promotion" to promote both fixed broadband and mobile broadband to enter the gigabit (G-bit) era, and to carry out demonstrations of gigabit broadband households. Favorable policies were released one after another. For example, in March this year, the Politburo meeting of the CPC Central Committee determined that “new infrastructure” represented by new infrastructure such as information networks will become an important increment for effective investment in the future and bring new opportunities for the upgrading of the information industry. In April this year, the State Council At the executive meeting, it was proposed that in accordance with the deployment of the Party Central Committee and the State Council, the construction of new types of infrastructure such as information networks should be speeded up, with "one industry leading to hundreds of industries", which will not only help industrial upgrading, cultivate new kinetic energy, but also promote entrepreneurship and employment, and benefit the long-term; the same In April, the National Development and Reform Commission for the first time clarified the scope of "new infrastructure", proposed to do a good job in project construction, and promote the optimization and upgrading of optical fiber broadband networks; at the press conference of the development of the industrial communications industry in the first quarter of 2020, a spokesman for the Ministry of Industry and Information Technology It also clearly put forward the principle of "preferring roads rather than cars, not allowing cars to wait", and stated that "The Ministry of Industry and Information Technology will accelerate the construction of new infrastructure such as 5G, Gigabit fiber optic networks, and data centers according to the national deployment."


Third, business application demand traction. The first four generations of fixed network technology are for home users. F5G is not only for the needs of home users, but also for enterprise users and industrial Internet applications. For example, in terms of home applications, video entertainment, online education, online medical care, remote office, smart home and other application scenarios drive the demand for F5G networks; in terms of enterprise applications, high-quality private lines, enterprise cloud, and all-optical parks are rapidly developing. To support the digital transformation of national pillar industries such as transportation, power, oil and gas, and finance; in industrial applications, industrial optical networks promote the improvement of industrial Internet capabilities, realize high-bandwidth, stable and green energy-saving networks that are resistant to electromagnetic interference, and open up all channels of information channels to promote Digitalization of industrial production.


Fourth, the full maturity of technical equipment supports the rapid development of F5G. Facing the F5G era, whether it is 10G EPON technology or 10G GPON technology, the standard has been completed five years ago, and related industries such as 10G PON chips and related optical modules have also matured to meet the needs of the business. As another key technology of F5G, a new generation of Wi-Fi technology has also matured. The Dell'Oro report pointed out that the global Wi-Fi 6 (802.11ax) market showed an explosive year-on-year increase in overall revenue in the first three quarters of 2019. The Wi-Fi 4 and Wi-Fi 5 markets experienced a slight decline 30 times a year; it is expected that by 2020, Wi-Fi 6 device sales will account for one-third of the entire Wi-Fi market.


Finally, telecom operators' business competition has also promoted the rapid development of F5G. According to the group's full-caliber data, as of the end of 2019, China Telecom, China Mobile, and China Unicom's fixed broadband users reached 179 million, 187 million, and 83.05 million, respectively, accounting for 38.1%, 39.9%, and 17.8%, respectively, and other operating companies accounted for Than 4.3%. From the trend of fixed broadband subscriber market share over the years, it can be seen that the market competition among telecom operators is fierce. At present, China Mobile has become the largest fixed broadband operator, and the fixed broadband subscriber market for non-basic telecom companies has declined significantly. Business competition will also promote operators to continuously upgrade their networks and continuously satisfy users' demands for bandwidth. F5G is now the main battlefield for competing for high-value broadband users.


At the end of the speech, Ao Li also called on the industry to build consensus and multi-party cooperation to seize the opportunities of fixed network intergenerational generation and rapid development of F5G. Including deepening research on F5G technical standards, accelerating F5G network construction and deployment, vigorously promoting innovative applications of Gigabit optical networks to create mature business models, and promoting the coordinated development of the optical network industry chain through F5G, etc.
