Since the Spring Festival of 2019, the concept of 5G (Fifth Generation Mobile Communication Network) has once again aroused market focus. So, what step has 5G taken in China?

According to Pengchao journalists, at the technical test level, according to the information released by 5G propulsion group, the third phase of 5G testing was basically completed by January 23, and the base station and core network equipment met the pre-commercial requirements. In 2019, 5G enhancement and millimeter wave technology R&D test will be launched.

According to the release rhythm officially disclosed, China will issue 5G temporary licenses in several cities this year, enabling large-scale networking to take the lead in some cities and hot spots, while speeding up the industrialization process and network construction of terminals. In the second half of the year, commercial products such as 5G mobile phones and 5G iPad will be used.

According to an insider of an operator, a 5G temporary license may be issued during World Telecom Day on May 17 this year, and a 5G official license is expected to be issued by 2020.

It can be seen that the 5G related bidding work of the three major operators has started. On January 31, China Mobile announced the results of purchasing wireless main equipment leased from a single source for the demonstration project of 5G scale networking construction and application in 2019. Five major equipment vendors, Huawei and ZTE, won the bid.

It should be pointed out that at the 5G global standard level, due to the delay of the R15 standard, the industry believes that the introduction of all 5G standards will be postponed until June 2020.

5G Standard: All standards will be released or postponed until June 2020

The 5G standard of the International Organization for Standardization of Communications (ISO) 3GPP is a big family concept. It is divided into two 5G schemes: non-independent networking (NSA) and independent networking (SA). The version of the standard evolves from R14, R15 to R16 and R17. The final version of the R17 will include all the standards involved in the three major scenarios of 5G.

In December 2017, the non-independent networking NSA standard of R15 was frozen. Non-independent networking is a transitional scheme, which mainly aims at improving bandwidth of hot spots. There is no independent signaling surface, relying on the work of 4G base station and core network, so the standard is relatively simple. In June 2018, the standard of SA's independent networking scheme was frozen. SA can realize all the new features of 5G, network slicing, edge computing and so on, which is conducive to exerting all the capabilities of 5G. After the freezing of the two standards, it also means that 5G industrialization has entered a full sprint stage.

However, the industry also believes that with the delay of 5G R15 completion time, the completion time of 5G R16 should be postponed accordingly. The completion time of the R16 standard will also be delayed from December 2019 to March 2020, which means that all 5G standards will be delayed to June 2020.

5G Technology Testing: The Third Phase Testing is basically completed

IMT-2020 (5G) Propulsion Group has organized three stages of planning, including telecom equipment manufacturers, chip manufacturers and operators. According to the information of IMT-2020 (5G), as of January 23, the third phase test of 5G was basically completed, and the base station and core network equipment met the pre-commercial requirements.

On January 23, the IMT-2020 (5G) Propulsion Group held the third phase summary meeting of 5G technology R&D test in Beijing.

Chen Lidong, deputy director of the Information and Communication Development Department of the Ministry of Industry and Information Technology, attended the conference and delivered a speech. Chen Lidong pointed out that China actively launched 5G technology R&D experiments, which played an important role in accelerating the maturity of 5G technology and industry. At present, the third phase of testing work is basically completed, 5G base station and core network equipment have reached the pre-commercial requirements. In view of the follow-up development of 5G, Chen Lidong said that we should accelerate the process of 5G network construction, actively explore 5G convergence applications, strengthen international cooperation and exchanges, and create an open and win-win industrial ecosystem.

At this conference, the IMT-2020 (5G) propulsion group released the third phase test results of 5G technology R&D test. The test results show that both 5G base station and core network equipment can support non-independent networking and independent networking modes. The main functions meet expectations and reach the pre-commercial level. Certificates have been issued to Huawei, ZTE, Datang, Ericsson, Nokia Bell, Qualcomm, Intel, Ziguang Zhanrui, Heise and other chip companies, as well as to Deutsche, Rhode and Schwartz. The Propulsion Group said that in 2019, it will start the 5G enhancement and millimeter wave technology research and development test.

Progress of 5G Branch Networks of Three Operators

China Mobile: On December 8, 2018, China Mobile officially launched 5G scale test and application demonstration, fully launched 5G test for commercial use, and promoted 2.6GHz and 4.9GHz synchronous test. The test was conducted in 17 cities, including Hangzhou, Shanghai, Guangzhou, Suzhou and Wuhan, and 12 cities such as Beijing, Chengdu and Shenzhen.

On January 24, 2019, China Mobile held the launch ceremony of 5G scale test independent networking (SA) centralized core network outfield test in Beijing, successfully completing the first multi-vendor, multi-provincial and multi-city 5G SA outfield end-to-end service verification and bandwidth test in the industry. The milestone achievements of 5GSA in outfield environment, such as over 1Gbps travel speed and 8K panoramic HD live broadcasting, mark that China Mobile 5GSA technology maturity and test progress have reached a new stage.

On February 12, 2019, China Mobile announced that China's first 5G Intelligent Highway project had landed in Hubei Province. At present, it is planning to select the high-speed section in the province for site selection of 5G base stations in the early stage, and simultaneously carry out intelligent toll testing. At the same time, 5G intelligent high-speed unmanned driving has entered the application test stage.

China Telecom: China Telecom has built 5G demonstration projects in 17 cities and carried out scale experiments. The goal is to achieve 5G commercial scale by 2020.

On February 13, 2019, Zhang Jianping, assistant chief engineer of Shanghai Telecom Company of China (Shanghai Telecom), told Peng Mei news reporter that Shanghai Telecom has begun to build 5G network in Hongqiao Business District of Shanghai, and is expected to provide the first batch of 5G capacity in the first half of this year.

Shanghai is the 5G pilot city of China Telecom. In addition, the 5G pilot cities of China Telecom include Xiongan, Shenzhen, Suzhou, Chengdu and Lanzhou.

On February 2, 2019, China Telecom announced that it had taken the lead in realizing 5G core network interoperability among different manufacturers, becoming the first operator in the world to achieve SA (independent networking) interoperability in accordance with international 3GPP standards. This will strongly promote 5G SA equipment to accelerate the formation of large-scale networking capabilities, making 5G R&D a key step towards large-scale commercial.

On January 20, 2019, at the Shenzhen Branch of CCTV Spring Festival Gala in 2019, China Telecom realized real-time 4K HD live broadcasting and video content return through 5G network. Through field test, the video picture from video source of camera to the broadcasting vehicle is stable through 5G network. The end-to-end delay is less than 40 milliseconds on average, and the whole process is smooth, without carton and interruption.

China Unicom: In June 2018, China Unicom released its 5G and network transformation plan. In 2019, it will carry out demonstration application and trial commercial use of 5G business scale. It is planned to be officially commercialized in 2020. China Unicom's deputy general manager, Maiyanzhou, said that China Unicom launched 5G pilot projects in 16 cities, pre-commercial in 2019 and commercial in 2020.

It is worth noting that each pilot city of China Unicom undertakes different tasks: Shenyang (industrial control), Tianjin (intelligent transportation), Qingdao (intelligent port), Nanjing (intelligent education), Shanghai (marginal computing), Hangzhou (e-commerce), Fuzhou (intelligent security), Shenzhen (intelligent finance), Beijing (intelligent Olympics), Xiongan (intelligent city). Zhengzhou (Intelligence Park), Chengdu (Intelligent Medicine), Chongqing (Vehicle Networking), Wuhan (Intelligent Water Conservancy), Guiyang (Intelligent Footprint), Guangzhou (Intelligent Logistics).

In the Spring Festival Gala of 2019, China Unicom and CCTV cooperated to use 5G network transmission. China Unicom has placed 5G indoor digital equipment in the main venue of Beijing, that is, CCTV, to achieve full coverage of 5G network in CCTV No. 1 studio. On-site audiences can experience 5G service by choosing 5G hot spots of China Unicom.

5G licence: Temporary licence will be issued this year

On January 10, Miao Wei, Minister of Industry and Information Technology, said in an interview with CCTV that this year, the state will issue 5G temporary licenses in several cities, enabling large-scale networking to take the lead in some cities and hot spots, speeding up the industrialization process and network construction of terminals, and using commercial products such as 5G mobile phones and 5G iPad in the second half of the year.

Miaoxu also stressed that in the future, about 20% of 5G facilities will be used for communication between people, and 80% will be used for things and things, things and people, that is, the Internet of Things, like future driverless cars.

One operator insider believes that 5G temporary licence may be issued during World Telecom Day on May 17 this year, and 5G formal licence is expected to be issued by 2020.

However, this idea has not yet been officially confirmed.
