China's communications technology, once in the 4G field, is striving for the upper reaches of 5G technology standards. On November 21, the official website of the Ministry of Industry and Information Technology announced that China has successfully completed the first phase of the 5G technology research and development test, and from September this year to September next year, the second phase of the 5G R&D technical test system verification test will be further carried out. The main work is based on unified equipment specifications and test specifications, and is tested against 5G typical scenarios. At the same time, the 5G network solution recommended by China's telecom companies has become an international standard for the first time. The industry generally believes that in the face of the upcoming 5G era, Chinese telecom companies that hold the right to standardize will gain more say, but also Can not relax the exploration of technology research and development and cost control.
5G technical standards break through European and American monopoly
Inspired by the broad prospects of 5G development, countries have recently increased their investment in scientific research. Wenku, Director of the Information and Communication Development Department of the Ministry of Industry and Information Technology, said that the second phase of China's 5G technology R&D trial will be based on a unified test platform, unified frequency, unified equipment and test specifications, targeting different applications for 5G mobile Internet and IoT. The technical solution is verified. At the same time, this stage will actively guide chip and instrument manufacturers to participate in the industrial chain docking test.
It is worth mentioning that not long ago, the research and development of China's 5G core technology has been recognized by the 3GPP of the International Mobile Telecommunications Standardization Organization. In particular, the Polar code promoted by China's telecom enterprise Huawei is adopted by 3GPP as 5GeMBB (Enhanced Mobile Broadband) control. Channel standard scheme. The person in charge of the Ministry of Industry and Information Technology said that this is an important progress in the research and standardization of 5G mobile communication technology in China. In this regard, telecom observer Fu Liang said that after long-term accumulation and investment in research and development, Chinese companies such as Huawei and ZTE have gradually increased their influence in the international market and have been recognized by various countries. This has invisibly enhanced China’s right to speak. "The 5G standard has the shadow of Chinese manufacturers. It is ridiculous to exclude Chinese telecommunications equipment in Europe and the United States in the future."
It is understood that China has adopted a different road from the international unified standards in 4G R&D and application, which has affected the development of the whole industry to a certain extent. Therefore, after the 4G is gradually popularized, all countries in the world including China have accelerated 5G. Research and development of technology. "A few years ago, China's telecom enterprises were relatively weak, and they could only produce some terminal communication equipment in the overall industrial chain, and they could not participate in the formulation of international rules." Senior industry analyst Liang Zhenpeng told the Beijing Business Daily that the Chinese telecom company For the first time, becoming a participant in standard setting not only means that the comprehensive strength of China's telecom industry is getting stronger and stronger, but also helps Chinese enterprises to have more intellectual property rights in the upcoming 5G era and no longer subject to people.
In fact, the industry generally believes that which country has more 5G advanced technologies, which country will have more international standard discourse rights, which will drive the development of a series of communications equipment industries. Specifically, due to the huge investment in the construction of a new generation of mobile communication networks, the performance of related devices, chips, antennas, software and other enterprises will increase, and stronger communication capabilities will break through the bottleneck, promoting the Internet, big data, the Internet of Things, etc. Enterprises are introducing new applications and solutions.
Enterprises scramble to snatch resources
As the development trend of future communication technologies, major enterprises are also rushing to research and develop 5G technology. At present, according to the deployment of the Ministry of Industry and Information Technology, the three major operators have actively carried out research and deployment of 5G.
This year, China Mobile announced that it will establish a 5G joint innovation center in Qingdao. In addition to developing and verifying 5G related technologies, it will conduct 5G application testing in various fields such as the Internet of Things and mobile medical. China Mobile has also recently cooperated with telecommunications equipment manufacturers such as Ericsson in a series of R&D and testing in the fields of network architecture and UAV applications. As early as 2012, China Telecom took the lead in launching 5G technology research and development, established a 5G evaluation system, supported cross-validation in the industry, and extensively carried out exchanges and cooperation with 5G research organizations, and cooperated with domestic and foreign equipment vendors to promote the 5G R&D process. According to the 5G standardization timetable proposed by the ITU, China Telecom has prepared for international standardization and has successfully obtained a number of 5G related 3GPP international standardization research projects represented by flexible duplex technology.
At the same time, China Telecom also took the lead in launching 5G technology research and development in 2012, has established a 5G evaluation system, supported cross-validation in the industry, and extensively carried out exchanges and cooperation with 5G research organizations, and cooperated with domestic and foreign equipment manufacturers to promote 5G research and development process. . According to the 5G standardization timetable proposed by the ITU, China Telecom has prepared for international standardization and has successfully obtained a number of 5G related 3GPP international standardization research projects represented by flexible duplex technology. In addition, China Telecom has also chosen to cooperate with companies such as Huawei and Beijing University of Posts and Telecommunications to conduct various tests on 5G networks, and has reached cooperation with various local governments such as Guangdong Province to conduct research and development and testing in related fields. The relevant person in charge of China Telecom said that after the 5G technical standard is determined, China Telecom will further deploy it as appropriate.
The relevant person in charge of China Unicom pointed out that China Unicom is actively following up the development of 5G and actively promoting it according to the unified deployment of relevant state departments. In terms of 5G future network, China Unicom is currently developing a 5G network architecture based on multi-level cloud collaboration to support end-to-end service solutions for mobile edge computing. China Unicom also announced that it will sign a 5G cooperation agreement with ZTE to jointly promote the 5G layout of China Unicom.
In addition to the three major operators, Huawei, ZTE, Nokia, Ericsson and other telecommunications equipment manufacturers are also accelerating the research and development of 5G key technologies. Among them, ZTE officially released the latest 5G high-frequency prototype at the Mobile World Congress in Barcelona held in February 2016, and jointly demonstrated key technologies such as 10Gbps+ high-flow and beam-tracking. Zhang Jianguo, senior vice president of ZTE and general manager of wireless product operation department, said that now in 2G, 3G and 4G, ZTE’s global stocks are gradually increasing, and 4G shipments have exceeded 20% globally. It should be said that ZTE is in 5G. The state of the aspect must be better than 4G.
Operating costs are still a problem
Despite the milestone, the opportunity to take the lead in standards must be maintained on the market side, and the relevant companies must not be taken lightly. In Liang Zhenpeng's view, participation in standard setting means that Huawei and other companies can share the same scores with other internationally renowned companies. Through patent cross-licensing, they will pay less part of the patent fee when developing communication equipment. "In addition, the promotion of the right to speak in the international market is also This means that in the future, the so-called standard level obstacles and bans encountered in the export of China's telecommunications products will be significantly reduced." However, he also reminded that China's telecommunications companies still have a lot of gaps from the operability of Qualcomm, and they still need to catch up.
For example, for enterprises, the new generation of mobile communication technology brings a lot of operating costs while bringing business opportunities. Some analysts pointed out that the investment return period of a telecommunications network is often around 7 to 8 years. The time for operators to build 4G is only about 5 years from the last 3G network, which means that they have not waited for 3G profit. The business began to build 4G, and the 4G investment return period is still not finished, and 5G has begun to rush. This huge “overdraft construction†will make operators feel heavy construction and operation pressure.
In addition, it is worthwhile to explore the problem of speeding up the cost reduction. In the 4G era, although the data transmission rate has been greatly improved, the complaints about high tariffs are very concentrated. Talking about the direction of speeding up and reducing fees in the 5G era, the relevant person in charge of China Telecom admits that since the current 5G standard has not yet been determined, the future business forms are still unclear, and it is still impossible to predict the 5G service tariff. However, Kang Hao, the editor-in-chief of the operator World Network, believes that after the opening of 5G, the operator's network speed will be greatly improved, and the tariff reduction will be inevitable, and will be greatly reduced, because operators will use the tariff reduction to encourage users to use more traffic, otherwise 5G network The idle rate will be high.
