A week ago, with the freezing of the independent networking function of the 5G mobile communication technology standard (5G NR) and the non-independent networking NR standard completed in December last year, 5G can be said to have completed the first phase of full-featured standardization work. Entered a new stage in the industry's full sprint.

At the 2018 IMT-2020 (5G) summit held on June 21, Wang Zhiqin, head of the IMT-2020 (5G) promotion team, also announced the latest developments in domestic 5G technology. She said that in the second half of the year, the working group will focus on the development of equipment for independent networking, while vigorously promoting the application of vertical industries.

“The work of the first phase of the 5G phase has ended, and everyone has started preparations in the second phase. Basically it is to realize the application of 5G to various industries, especially the specific applications that can support Industry 4.0 and involve every aspect of everyone’s life. "In an exclusive interview with the First Financial Reporter, Wu Geng, chief technical expert of Intel's wireless technology and standards, said that the evolution of 5G is not only a challenge for the global industry, but also a huge business opportunity. It involves our lives. All aspects, from self-driving cars to smart homes, from manufacturing to virtual reality, from medical to mobile office.

5G walks out of the lab

The release of the first 5G independent networking (SA) standard means that Release 3 of the 3GPP's first complete 5G standard is formally launched, and the 5G industry chain has entered the commercial phase.

Previously, in order to support countries and operators that have achieved 5G precommercial use in 2019, 3GPP completed the 5G Non-Independent Networking (NSA) standard in advance in December 2017 to support operators to develop on the basis of the existing 4G core network. 5G mobile broadband services. The landing of the standard is half a year earlier than the original planned time. Thanks to this, the 5G network equipment and terminal productsDevelopmentThe rhythm has been advanced six months ahead of schedule and it is expected to reach commercial use by the end of 2019.

Asha Keddy, vice president of Intel's Technology and System Architecture and Client Division, said: "The industry is taking more steps to push forward 5G, and the pace of commercialization has changed from walking to jogging and running. It has now begun full-scale sprint."

The First Financial reporter noted that many manufacturers have started more 5G field tests, and the technology is no longer confined to the laboratory.

With the landing of the SA standard, China Telecom stated that it plans to expand the existing urban outfield test to lead the 5G performance verification and network function optimization. China Mobile announced that it will build two new 5G base stations in Shanghai, and it is expected that more than one hundred 5G base stations will be built during the year. This target surpassed that of Guangdong Province this year. China Unicom is also announcing the opening of 5G base stations in many places, of which Guizhou Unicom has achieved a test rate of 1.8 Gbps.

In addition, Huawei, Intel and Ericsson all show 5G "muscle." Huawei stated that it will take the lead in completing all the use case tests for the third stage NSA (non-independent networking) of China's 5G technology R&D trials organized by the IMT-20205G promotion group. Last week, at the Ericsson Beijing Laboratory, Ericsson, Intel, and China Mobile Research Institute and Jiangsu Corporation launched 3G new air interface interoperability tests conforming to the 3GPP SA standards, and achieved heterogeneous vendor data transmission at 100 MHz bandwidth in the 3.5 GHz band. Real-time rate up to 1.3Gbps.

Finding applications

From the technical perspective, 5G is not only the next-generation mobile technology, it is a brand-new network that connects all things in an optimal way. This unified connection architecture will extend the advantages of mobile technology to new industries. , and create a new business model.

From a development perspective, the previous 5G standard defines three major scenarios, eMBB, mMTC, and URRLLC. Among them, eMBB corresponds to 3D/Ultra HDvideoSuch as a large number of mobile broadband services, mMTC corresponds to a large-scale Internet of things, and URLLC corresponds to such services as unmanned driving and industrial automation that require low latency and high reliability.

However, from an application perspective, in addition to the very clear market of mobile broadband, the two major technology directions of eMTC (massive internet of things) and URLLC (ultra low latency) have been different from the original ideas.

"If you look at the results, you never guessed." Wu Geng told reporters that there is a business model problem that needs to be solved between industries, and there is a problem of running-in between industries. The technical requirements are still relatively easy to solve. The laws of physics, but what kind of new partnerships will arise between different equipment vendors, operators, etc. in the industrial value chain, needs to continue to be explored.

Wu Geng believes that 5G is by no means a simple air interface innovation and transmission speed improvement, but will be out of the scope of communication links, through the deep integration of communications, computing and vertical industries, bringing a far-reaching intelligent digital economic revolution.

"5G is a true success only if it succeeds in the vertical industry. From the standpoint of standards, it is necessary to establish a cross-industry, global, and ultra-large-scale mechanism for the development of new technology platforms." Wu Geng said that apart from Actively participating in other standards organizations such as 3GPP, Intel is also actively participating in some cross-industry standard projects and has played a very important role in guiding and enabling.
