(Text/Editor Lv Dong/Yin Zhe) On the same day that the United Kingdom announced that Huawei would be banned, Samsung happened to release a 6G white paper and also predicted the commercial timetable for 6G.

On July 14, Samsung mentioned in its 6G white paper that 6G technology will provide 50 times the peak rate of 5G networks, with a delay of one-tenth of 5G. In addition, the completion and commercialization of the 6G standard will be as early as 2028, and large-scale commercialization may be around 2030.

According to the plan announced by the UK yesterday, UK mobile operators will be prohibited from buying Huawei 5G equipment from next year, and the used Huawei equipment will be removed by 2027.

Just a few days before Huawei was blocked by the United Kingdom, Samsung said to the United Kingdom that it “has sufficient capacity to provide it with a new 5G network” and intends to “take advantage of it.”

However, in the global 5G telecommunications equipment market share, Huawei has currently achieved 35.7%, leading Samsung by 9.3%.

Ren Zhengfei:6G has not yet been theoretically Breakthrough

On July 14, Samsung released a white paper on”Next-Generation Hyperconnected Experience”, explaining its vision for the next-generation communication system, namely 6G. It covers all aspects related to 6G, including technology and social megatrends, new services, demand, candidate technologies and expected standardization schedule.

The Yonhap News Agency believes that the white paper reflects Samsung’s willingness to accelerate technological R&D to seize the commanding heights of competition.

To accelerate research on 6G technology, Samsung Electronics established the Advanced Communication Research Center in May last year. The company expects that the completion of the 6G standard and the earliest commercialization may be in 2028, while large-scale commercialization may be around 2030.

The white paper points out that the requirements of 5G are mainly focused on performance, and Samsung defines three types of requirements that must be met to achieve 6G services:performance, architecture, and credibility.

Among them, the requirements for 6G performance include a peak data rate of 1000Gbps and an air delay of less than 100μs, which is 50 times the peak data rate of 5G, and the delay is one tenth of 5G.

In addition, the white paper also introduces the candidate technologies necessary to meet the requirements of 6G, including the use of the terahertz (THz) frequency band and new antenna technology to improve the coverage of high-band signals , Advanced duplex technology, evolution of network topology, spectrum sharing to improve frequency utilization, and the use of wireless communication AI technology.

At present, many countries in the world have started 6G research, such as China, the United States, Finland, and South Korea.

Among them, the Ministry of Industry and Information Technology of China began to study the development of 6G as early as the end of 2017. In October 2018, the Ministry of Science and Technology released the”Broadband Communication and New Network” key special 2018 project, which involved B5G/6G wireless mobile There are 5 projects in communication technology and standard R&D.

In November last year, the Ministry of Science and Technology, together with the National Development and Reform Commission, the Ministry of Education, the Ministry of Industry and Information Technology, the Chinese Academy of Sciences, and the Natural Science Foundation of China organized a 6G technology R&D work start-up meeting in Beijing and established a national 6G technology R&D promotion working group And the overall expert group, China 6G R&D officially started.

On November 3, 2019, the Ministry of Science and Technology, together with the Development and Reform Commission, the Ministry of Education, the Ministry of Industry and Information Technology, the Chinese Academy of Sciences, and the Natural Science Foundation of China, organized a kick-off meeting for 6G technology research and development in Beijing.

Compared with the Ministry of Industry and Information Technology, the National Development and Reform Commission, and the Ministry of Science and Technology participating in the organization of 5G research promotion group in 2013, the 6G research started to join the Ministry of Education, the Chinese Academy of Sciences and the Natural Science Foundation of China, reflecting a greater Organizational strength and importance also tend to increase support for basic research.

The industry generally believes that the 6G frequency band will be expanded from the 5G millimeter wave band to the terahertz (THz) band. The data transmission rate is expected to be 100 times faster than 5G, and the delay will reach the level of sub-millisecond level. It is used in the fields of Internet of Things, industrial Internet, unmanned driving, etc.

However, Observer Network columnist Bao Dao pointed out that whether terahertz can be used for wireless communication is still being demonstrated. It is characterized by high frequency and high communication rate. In theory, it can reach terabytes per second (1TB per second), but the disadvantages of higher frequencies are also obvious. The transmission distance is short and it is susceptible to interference from obstacles. Higher communication frequency also puts forward higher requirements on the performance and processing technology of hardware equipment.

He pointed out in the article that the basic principle of the millimeter wave technology used in 5G was completed as early as 2000, and it took more than ten years for the industry to develop maturely. As antennas become smaller and electronic components become more sophisticated, terahertz communication will only become more difficult.

It is worth mentioning that Huawei President Ren Zhengfei mentioned in an interview in May this year that Huawei has been doing 6G and is synchronized with 5G, but 6G has not yet broken through in theory, so it should be used by humans. After ten years. Last September, he revealed that Huawei is leading the world in 6G research.

Samsung or”Take advantage of it”

It happened that Samsung’s 6G white paper was released on the same day as Huawei was”blocked” by the United Kingdom.

On July 14, local time, the British government announced that it would ban British mobile operators from purchasing Huawei 5G equipment from 2021, and dismantle used Huawei equipment by 2027.

Donden, the British Minister of Culture, admitted that excluding Huawei would delay the country’s 5G construction by one year.

Just a few days before the decision was made in the UK, Reuters reported on July 9 that Samsung’s executive vice president (Woojune Kim) said that Samsung is currently capable enough to provide the UK with a new 5G network. The company Negotiations with European operators on the supply of network equipment.

The report believes that based on the recent British attitude, Samsung may “replace” Huawei to provide relevant technologies for the country’s 5G construction.

However, in terms of 5G equipment market share, the gap between Samsung and Huawei is still very obvious.

Dell’Oro survey report shows that in the first quarter of 2020, Huawei ranked first with a market share of 35.7%in the global market share of 5G telecommunications equipment, leading the second place Ericsson by a large margin, the latter The share is 24.6%. The third to fifth place are Nokia 15.8%, ZTE 13.2%, Samsung 9.3%. It can be seen that two Chinese companies, Huawei and ZTE, occupy nearly half of the global market share.

It’s amazing that Samsung has achieved certain first-mover advantage in the 5G telecommunications equipment market, and it was the first to launch in the third quarter of 2018. 5G base station chip, and successfully measured production in four seasons, coupled with South Korea’s 5G network construction took the lead at the time, Samsung also benefited.

In addition, due to the exclusion of Huawei’s telecommunications equipment by the United States and its allies, telecom operators in the United States and its allies have also signed some 5G equipment purchase agreements with Ericsson and Nokia. 5G orders are distributed to Samsung.

For example, in September 2018, AT&T, the second largest operator in the United States, selected Nokia, Ericsson, and Samsung as the main suppliers of its 5G deployment projects.

Under the influence of these factors, Samsung successfully climbed to the top of the global market share of 5G telecommunications equipment in the fourth quarter of 2018 and won a market share of up to 37.8%in the first quarter of last year.

However, with the large-scale shipment of 5G base stations from Chinese telecommunications equipment manufacturers Huawei and ZTE, Samsung’s market share has begun to decline rapidly, changing from market share first to fifth within a year.

In response to the UK’s decision to block Huawei, the country’s operators Vodafone and BT had previously warned British lawmakers that they would need at least 5 years, or even 7 years, to recover the impact of giving up Huawei on the UK’s network construction, but the UK The government is still determined to implement the ban.

Regarding this, a spokesperson for Huawei UK said that this decision was a disappointment. Unfortunately, Huawei’s future development in the UK was politicized. This move stems from US trade policy, not security issues. The company urged the government to reconsider this decision.

China’s ambassador to the UK Liu Xiaoming also said on social media that the UK has made a disappointing wrong decision on the issue of Huawei. Can the UK provide an open, fair and non-discriminatory approach to companies in other countries? Business environment has become a problem.
