2021-02-04 11:09:53 13

In 2020, the new crown epidemic will spread all over the world, which will have a huge impact on the world economy and force traditional enterprises to develop in the direction of "online, digital, and intelligent".


Suddenly, the demand for Internet communication has surged, and remote office, online education, video conferencing, etc. have become social norms and are accepted by more and more users. The overall Internet traffic has also increased significantly compared to previous years.


TeleGeography data shows that the online economy triggered by the new crown epidemic in 2020 has increased Internet bandwidth by 35%, driving the average international Internet traffic to rise by 48% and peak traffic by 47%.


At the same time, my country has vigorously promoted the "new infrastructure" strategy, consolidating the new cornerstone of the digital economy by improving the layout of communication network infrastructure such as 5G, the Internet of Things, and the Industrial Internet, and opening the era of the Internet of Everything.


On the whole, opportunities and challenges coexist in the communications industry in 2020. In this regard, we have extracted the "three major" keywords: 5G, 400G, and Wi-Fi 6.



1. China has built the world's largest 5G network


In 2020, my country will appropriately deploy 5G networks ahead of schedule, vigorously promote the construction of 5G networks through co-construction and sharing, and form extensive coverage of all prefecture-level and key counties and districts across the country.


As of the end of 2020, my country has built more than 600,000 5G base stations, opened more than 718,000 5G base stations, promoted the construction of 330,000 shared 5G base stations, and built about 800 5G virtual private networks.


The three major basic telecom operators (China Telecom, China Mobile, and China Unicom) have all achieved nationwide 5G independent networking (SA) large-scale commercial use in 2020.


According to statistics from the Global Association for Mobile Communications Systems, China’s 5G infrastructure is the largest in the world so far, and China’s 5G connections account for more than 75% of the world’s total.


The international standards organization 3GPP announced the freezing of the R16 standard, marking the completion of the first evolutionary version of 5G. my country comprehensively promotes the development of the R16 standard, and the results of the promotion cover all topics of R16.


The development of 5G applications has entered the lead-in period, enabling the high-quality development of thousands of industries, including 5G+ mining, 5G+ medical, 5G+ industrial Internet, and 5G messaging, 5G cloud gaming and other applications have gradually landed.


In the next 2-3 years, 5G network technology will be more prominent in terms of enhanced Internet of Vehicles, ultra-high reliability and low-latency communications, millimeter wave technology, etc., to better support various industry applications and improve overall technical support capabilities.


According to the "White Paper on China's 5G Development and Economic and Social Impact (2020)" released by the China Academy of Information and Communications Technology, 5G will directly drive total economic output of 810.9 billion yuan in 2020.

2. The era of 400G data center is coming


In recent years, global data traffic has continued to rise, prompting the development of data centers from 100G to higher speed, greater bandwidth, and lower latency. 400G Ethernet has become an inevitable trend in data centers.


The application of 400G data center will profoundly affect the ecology of the industrial chain, and it is expected to start a new round of growth cycle in the data communication equipment market such as optical modules, switches, and routers.


Undoubtedly, 2020 is a crucial year for the "commercial" of 400G products. Mainstream manufacturers such as Cisco, Huawei, and Xinhua III have carried out related research and development and proposed their own 400G solutions.


The 400G solution can greatly improve network performance, thereby reducing network operation and maintenance costs, and promoting the development of 25G, 100G, and optical fiber markets.


Although the domestic 400G optical module industry has been turbulent in advance, the deployment of 400G has been slow due to power consumption and price. Omdia predicts that by 2025, 400G shipments and revenue will be dominant.


According to the latest report of Dell’Oro Group, the number of 400Gbps ports will continue to grow in the next five years, and the shipment of 400Gbps switch ports will exceed 15 million.



3. Wi-Fi 6 shines in the wireless market


If we say, 2019 is the year of popularization of Wi-Fi 6 concept. Then, 2020 is the year of Wi-Fi 6 exploration.


In 2020, the Wi-Fi Alliance announced that Wi-Fi 6 will be expanded from the existing 2.4GHz and 5GHz frequency bands to the 6GHz frequency band, and will be named "Wi-Fi 6E".


The Wi-Fi Alliance believes that Wi-Fi 6E is expected to support high-definition video, VR and other applications that require faster, larger bandwidth capacity, and lower latency networks through additional spectrum capacity.


ABI Research pointed out that during the outbreak of the new crown epidemic, Wi-Fi upload traffic surged by 80%, which once again proved the user's demand for Wi-Fi 6/6E and Wi-Fi Mesh applications.


The popularity of Wi-Fi 6 in China has been speeding up in an all-round way, and the industry chain enterprises are facing development opportunities. Chip giants, network suppliers, mobile terminal and smart home manufacturers have entered the game in an attempt to get a share of the pie.


The new Wi-Fi brand launched by Huawei and deployed in five major regions around the world demonstrates its ambitions as a communications giant. Ruijie Networks focuses on a good wireless experience and provides users with Wi-Fi 6 products in all scenarios.


According to the "China WLAN Market Tracking Report, 18Q4" released by IDC, Unigroup's New H3C Group ranked first in the market with a market share of 31.1%.


IDC predicts that by 2023, Wi-Fi 6 will account for more than 90% of China's wireless AP market shipments. In the future, China's Wi-Fi 6 market will be more imaginative.
