Last month, the 3GPP International Standards Organization officially announced at the 5G International Standards Plenum held in Lisbon, Portugal, that the first version of the 5G New Radio (NR) international standard for non-independent networking was completed as planned. This means that for 5G networks, the global industry has the first official relevant standards, laying the foundation for large-scale trials and commercial deployment.
The launch of the first 5G NR international standard means that the global 5G industry has officially started. It also marks the 5G independent networking standard and industrialization process has entered a substantial acceleration stage, and 5G commercialization has officially entered the countdown.
According to the 3GPP plan, 5G standards are divided into NSA (non-independent networking) and SA (independent networking). This time the 5G NSA standard is released. NSA does not have an independent signaling plane and still needs to rely on 4G base stations and 4G cores. It is a transition plan for SA independent networking. The 5G NR standard for the true SA independent networking will not be completed until June 2018. At that time, the standard may be slightly adjusted, but it will not affect the product design direction of the manufacturer before this, because the core standard has been established, and there will be no major changes in the future.
The official version of the 5G standard will cover a wide range of frequency bands, from the 600 and 700 MHz frequency bands to the millimeter wave part of the 50 GHz frequency band. In China, the Ministry of Industry and Information Technology also recently announced a specification for the use of 5G in the 3000-5000MHz frequency band, which is also covered by this standard. With the completion of the first version of the 5G NSA standard, operators will conduct 5G field tests in multiple major cities in 2018 and prepare for the upcoming 5G commercial use.
What I want to point out here is that, unlike the previous formulation of communication standards, Chinese companies have a lot of say in the formulation of 5G standards. Huawei, ZTE and Chinese operators have made considerable contributions to the release of 5G standards. In particular, China Mobile, as the sole reporter and chief editor of the agreement, led the completion of 5G air interface scenarios and demand research projects, and output 5G air interface technology programmatic documents. All subsequent technology development and standardization will be based on this document. This is a big history Sexual leap.
Looking at the entire history of the development of China’s communications industry, from following the 1G and 2G era, to participating and controversial in the 3G era, to catching up and partaking in the 4G era, to the leading formulation of standards in the 5G era, it fully demonstrates China’s communications technology strength Has been recognized by the industry. As we all know, global communication technology standards have always been monopolized by foreign giants. This time China Mobile, ZTE, and Huawei have led the formulation of 5G standard wireless air interface technology standards, which is an important symbol of China's increasing right to speak in the formulation of international communication technology standards.
After the release of the 5G NSA standard, the next step is to see how operators and hardware manufacturers turn 5G networks from theory to reality. In 2017, the three major operators have launched 5G pilot work in Beijing, Shanghai, Chongqing, Guangzhou, Nanjing, Suzhou, Ningbo and other cities. It is foreseeable that 2018 will be the beginning of large-scale pilot work by operators. The editor believes that, in addition to end-to-end verification of 5G key technologies, network performance and commercial networking capabilities, the pilot will also rely on the ultra-high bandwidth, ultra-large connections, and ultra-low latency of 5G networks to provide new experiences and haptics in AR and VR. Research and experiment on vertical applications such as the Internet, the Internet of Vehicles, and real-time video return and control of UAVs.
The reporter learned that China Telecom plans to carry out 5G laboratory and field tests in 2017-2018, and launch trial commercial deployment in 2019, and achieve large-scale commercial use around 2020; China Unicom will conduct 5G trial commercial trials in 2018 and trial commercial use in 2019 , Will be officially commercialized in 2020; China Mobile will select more cities to participate in the pilot in 2018 based on the 5G pilot cities in 2017, and plans to launch 5G network deployment in due course after the first international 5G version is announced in 2018, and Strive for commercial 5G networks in 2020.
In the editor’s opinion, the choice of the 5G NSA standard to be released at the end of 2017 is not only the perfect termination of one process, but also the beginning of another process! Because the independent network 5G SA standard is the industry-recognized 5G target solution, it can be achieved All the new features of 5G and the full use of 5G capabilities, but this does not affect the process of 5G commercial use. Conversely, the release of the 5G NSA standard is a critical transition in the establishment of the 5G SA standard. NSA's transition standard has come, and the SA independent network standard will naturally not be far away!
