Gathering micro-network news, local time: June 18, 2018, 20:18 (Beijing time: June 14, 2018, 11:18), 3GPP Plenary (TSG#80) approved the 5th generation mobile communication technology standard (5G NR) Independent networking function freezes.
In addition to the non-independent networking NR standard completed in December last year, 5G has completed the first phase of full-featured standardization work and entered a new phase of full-scale industrial sprint.
This freezing of SA functions not only enables 5G NR to have the capability of independent deployment, but also brings a new end-to-end new architecture, enabling the intelligent development of enterprise-level customers and the vertical industry, bringing benefits to operators and industry partners. The new business model opens a new era of full connectivity.
More than 600 representatives from the world's major telecom operators, network equipment vendors, terminal and chip manufacturers, instrumentation vendors, Internet companies and other vertical industry companies have witnessed this historic moment.
It is reported that, unlike the previous non-independent networking 5G Release15 NSA version, the complete 5G Release15 version SA (Standalone independent networking) determined this time adopts a new architecture. In addition to adopting new network elements and interfaces, it is also large-scale. Supports software-defined networking, network virtualization and other technologies. 5G will be separated from 4G independently. This facilitates operators to develop a variety of services. Reliance on 4G is also reduced to 5G to improve bandwidth and low latency. .
According to the Ministry of Industry and Information Technology, China's 5G carrier frequency band is midrange, and Sub6GHz is also within this published standard. According to an announcement from the Ministry of Industry and Information Technology, the 3300-3600MHz and 4800-5000MHz bands are planned to be used as working frequency bands for 5G systems, and 3300-3400MHz band is also available. In principle only for indoor use.
It is reported that Release 16 will be the next 5G standard, and standard setting work will be completed in December 2019. At that time, the 5G plan will be completely determined.
Balázs Bertényi, chairman of the 3GPP TSG RAN, stated: 'The freezing of the 5G NR radio protocol is an important milestone for the wireless industry to explore the 5G vision. The 5G NR SA system not only significantly increases the network speed and capacity, but also opens up new industries. The 5G system is the gateway to industrial ecosystem changes.
The key changes brought by 5G
The key changes brought about by 5G are three things: faster speeds, the ability to accommodate more users at the same time, and lower network time delays. It can provide faster network speed for each device while satisfying The load of high-density device networking can also reduce the network latency of data.
These 'advanced' features will greatly expand the application of wireless communication technologies: From your home's IoT devices to autonomous driving, urban dynamic wireless mesh networks, etc., these new wireless communication products will continue to enhance us. If you have no idea about these things, you can actually summarize them in one sentence. In the era of 5G, not only wireless communication technologies will be unified, but even some wired network transmissions will be replaced by wireless communication.
According to the information released by the Ministry of Industry and Information Technology at the Digital China Construction Summit in April, China's first batch of 5G chips will be taped out before New Year's Day in 2019, and will be completed before and after the Spring Festival. According to the plan, 5G will start pre-commercial use in 2019, and commercial use will be carried out in the first half of the year. Base station construction, the first batch of 5G handsets was produced in the second half of the year and was officially commercialized in 2020.
Counterpoint Research and Ernst & Young, market research companies, also issued reports that the commercial use of 5G smart phones will start in 2019 and begin explosive growth in 2021.
In its report, Ernst & Young predicts that China will invest approximately 1.5 trillion RMB in 5G construction between 2019 and 2025, and achieve 5,776 million 5G subscribers in 2025. This number will be 40% of the global 5G subscribers at the time. Counterpoint Research believes that by 2021, 5G smart phone shipments will exceed 110 million units.
