The 4G network is not fully covered yet, and the 5G network is here! According to the daily economic news, recently, at the World Mobile Communications Conference, 5G technology has once again become the focus, and major operators and mobile phone manufacturers have begun to deploy 5G services.
From the application submitted by the operator to the Ministry of Industry and Information Technology, China's three major operators will carry out 5G pilot projects in 13 cities, including cities in the north, Guangzhou, Shenzhen, Wuhan, Chengdu, Tianjin, and Nanjing. Among them, Mobile will first launch 5G testing in five cities: Hangzhou, Shanghai, Guangzhou, Suzhou and Wuhan. In addition, it will conduct 5G services and application demonstrations in 12 cities including Beijing, Chengdu and Shenzhen, covering 4K HD. , augmented reality, virtual reality, drones, etc.
The pilot cities of Unicom are: Beijing, Tianjin, Shanghai, Shenzhen, Hangzhou, Nanjing, Xiong'an; pilot cities for telecommunications: Chengdu, Xiong'an, Shenzhen, Shanghai, Suzhou, and Lanzhou. It is worth noting that among many cities, Shanghai is the only city where the three major operators are piloting.
According to reports, Ma Hongbing, deputy general manager of China Unicom's network construction department, recently revealed that the field construction work has been completed in Shanghai and Shenzhen. Huawei, ZTE and Nokia's 5G prototype laboratory verification and partial field performance verification have also been completed.
The third phase of the 5G technology R&D test was officially released in Beijing. 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 will basically reach the pre-commercial level.
According to previous news, China is expected to achieve 5G commercial trials in 2019 and officially large-scale commercial use in 2020. So which 5g listed companies are better? The following are four listed companies that are recommended by Xiaobian.
1. ZTE Corporation (32.360, 0.12, 0.37%)
ZTE Corporation issued a document on its WeChat public account on the 22nd, saying that the company focuses on 5G core technology. After years of research and layout, it has become a major contributor to the global 5G standard research. The company has a full range of 5G end-to-end products, from wireless access, core network, transmission to network management and operation, covering different frequency bands, applicable to different scenarios, leading in product performance. Actively carry out 5G testing with operators and partners, achieve a number of test technology leadership, and vigorously promote the 5G commercial process.
Bo Yanmin, general manager of ZTE's TDD&5G products, said: "The 5G technology R&D test organized by IMT-2020 5G promotion group is a key link in the 5G development process. It promotes 5G key technology research and development, verifies 5G technology solutions, and supports global unified 5G standards. The development is of great significance. As a 5G pioneer, ZTE will fully invest in 5G, and will continue to invest sufficient resources in the third phase of 5G technology research and development, fully support the national 5G strategy, and strive to promote 5G technology research and development. With the development of the industry, it will lay a good foundation for China's 5G commercial use in 2020."
2. Fiberhome Communications (29.200, 0.78, 2.74%)
Recently, China Telecom successfully conducted the first 5G OTN preamble bearer test at the Beijing Research Institute. This is the eCPRI interface for the 5G preamble released by the CPRI (Common Public Radio Interface) Alliance of the Global Wireless Industry Standards Organization in August 2017. Since the standard, the world's first transmission bearer test for 25G rate eCPRI has far-reaching industrial guiding significance.
The test was launched in late January 2018. Major communications equipment vendors such as Huawei, ZTE, and Campfire responded positively and successfully completed the test. The test results show that the three mainstream manufacturers 5G OTN pre-transmission equipment can support the mainstream 25G eCPRI pre-transmission interface transmission, and it is excellent in key performance indicators such as delay and delay jitter. Even for the most demanding uRLLC (Ultra-Reliable & Low Latency) business scenario (for autopilot services) in 5G applications, the 5G OTN preamble device shows a single order of 1 microsecond (us) Excellent performance such as node transmission delay and nanosecond (ns)-level delay jitter can meet the load-bearing requirements.
5G commercial, bear first. China Telecom said that it will provide the most excellent transmission performance for 5G bearers through the cooperation of upstream and downstream of the solidarity industry, which will bring unlimited possibilities for the expansion of 5G innovative services.
3. Datang Telecom (8.390, -0.01, -0.12%)
Datang Mobile, which belongs to Datang Group and Datang Telecom, actively participated in the testing of the three stages of 5G R&D.
Cai Yuemin, deputy chief engineer of Datang Mobile, said that in the second phase of the 5G test, Datang maintained its leading position in technology and products. In each scenario, each key technology is tested in combination, and all key scene test rooms and field technical verifications on the wireless side have been completed, and a satisfactory answer sheet is handed over. On the network side, all key technology verifications have also been completed. It is the manufacturer that completed the second phase of the 5G technology R&D test on the network side, including all the use cases of performance testing.
He said, "According to the 3GPP roadmap, 5G is expected to be officially commercialized by 2020, so the time left for the industry chain is not sufficient."
Therefore, Datang has developed a strict time plan for the third phase of testing. From January to April 2018, eMBB NSA field construction will be completed; from April to July, eMBB NSA laboratory and field test will be completed; from July to October, eMBB SA laboratory and field test will be completed, and eMBB indoor coverage will be completed at the same time. The test; uRLLC will complete the field test in Q4; the millimeter wave laboratory and field test will be scheduled in the second half. On the network side, Datang plans to complete the 5G NSA test from April to July 2018; the 5G SA test is completed from July to October of the same year; and the 5G interoperability test is completed from October to December.
4. Sanan Optoelectronics (25.820, 0.18, 0.70% )
As the earliest and largest-scale full-color ultra-high brightness LED epitaxial and chip industrial production base in China, Sanan Optoelectronics plays an important role in the 5G phase III test.
In December last year, Sanan Optoelectronics announced that it had officially approved the wholly-owned subsidiary Sanan Integration to take charge of the project according to the central government financial budget of the core electronic components, high-end general-purpose chips and basic software products issued by the Ministry of Finance in 2017. The central government's financial budget is used for the related work of the implementation of major nuclear high-level projects.
The project name undertaken by Sanan Integration is 5G mobile communication power amplifier chip industry technology research and development and platform construction. The project cycle is 4 years, and the central government budgetary total subsidy is 863.126 million yuan, which is paid in installments. Sanan Integration has received the first phase of financial subsidies of 32,804,800 yuan.
Changjiang Securities (7.470, 0.00, 0.00%) believes that the nuclear high-base project of 5G power amplifier chips is of far-reaching significance for Sanan. This indicates that Sanan Integration will become the platform for domestic R&D 5G power amplifier chips, and it is the national recognition of Sanan integration, and also gives Sanan integrated leading position in the power amplifier industry.
There are also some companies that are not listed on the A-share market, and they are also involved in the research and development of China's 5G Phase III.
