A key step in the commercialization of 5G technology

Reporter Huang Xin

On January 17, Ericsson introduced a wireless small cell product, the 5G wireless point system. This product supports the new 5G mid-frequency band (3-5GHz) at speeds up to 2Gbps. Zhang Zhiwei, chief marketing officer of Ericsson Northeast Asia, frankly stated that the new product's preference to support the mid-frequency band is precisely because the main direction of China's 5G market is currently midrange, and Ericsson has assessed the global 5G market and believes that China will develop rapidly.

"China's 5G's first choice of frequency bands is intermediate frequency 3.5GHz and 4.9GHz, because its coverage and coverage of existing networks is very high. China's priority development of IF has led the global industrial chain to tilt in this area, especially 3.5GHz The global industrial chain has even been shaped,” said Peng Junjiang, general manager of Ericsson’s Northeast Asian Development Center.

On January 16, China's IMT-2020 (5G) Promotion Team formally issued the third phase of the 5G technology R&D experiment. Wen Ku, director of the Department of Information and Communications Development of the Ministry of Industry and Information Technology, announced that China's 5G technology test "Primary school graduated and officially entered secondary school!"

The third phase of the 5G technology R&D experiment will be a key step before 5G is commercialized. The formulation and release of the third phase of the 5G technology test is particularly important. Wenku emphasized that in the third phase, it is necessary to combine 5G frequency planning and synchronously advance development of 3.5GHz and 4.9GHz.

According to Xu Fei, head of the 5G test working group of the IMT-2020 (5G) promotion group, spectrum is an important basis for 5G development. Except for the 3.5GHz band that can already be used for trials, 4.9GHz will be equally important. The high frequency band meets the extremely high user experience rate and system capacity requirement in the hot spot area, and the low frequency band satisfies the requirements of large coverage and high mobility scenarios.

Xu Fei also said that the main objectives and tasks of the third phase of the trial include: based on 3GPP 5G standards, focusing on China's 5G requirements, requesting 5G products, road signs, etc., guiding 5G pre/commercial product R&D, and accelerating 5G work; Unified environment, testing of single-system, single-terminal, networking, and interoperability, to promote product maturity and industrial chain synergy, lay a common foundation for the full-scale development of 5G scale trials; carry out 5G typical application integration tests, and promote the development of 5G services and applications.

It is reported that through the third phase of the 5G technology R&D test, it is expected that by the end of 2018, the main links of the 5G industry chain can basically reach the level of pre-commercial use, promote the development of 5G better and faster, and lay the foundation for 5G scale testing and commercial use.

The latest release of the Ericsson Mobile Market Report shows that early deployment of 5G is expected to take place in several markets, including the United States, South Korea, Japan and China. The first batch of commercial networks based on the independent networking of 5G new air interface technology is expected to be put into use in 2019. Most network deployments will start from 2020. It is estimated that by the end of 2023, the number of enhanced mobile broadband 5G users will exceed 1 billion, and the number of smartphone subscription users is expected to reach 7.3 billion. It is expected that the number of contracted users will reach 5.5 billion by the end of 2023. By then, the proportion of LTE users to the total number of mobile users will exceed 60%.

Peng Junjiang stated that the 5G Phase 3 test is for commercial system verification. This means that multi-vendors must achieve end-to-end interconnection and interoperability. Through continuous testing and cooperation, a unified and commercially available best solution is finally formed. Program.
