Recently, CCTV Financial Channel "Transaction Time" column reported that 5G commercialization will be gradually promoted this year. In 2018, 5G will be commercialized in several cities in China. Many overseas operators are also preparing for the pre-commercial pilot. In June this year, 5G The international standard was introduced, and the 5G prologue was about to be opened.
ZTE’s chief scientist told Interview that “ZTE and China Mobile have cooperated to complete the air interface docking test of the 5G version of the 3GPP R15, and the trials have been opened with Telecom and China Unicom. The third phase of the Ministry of Industry and Information Technology also Passed quickly, the pass rate is 100%."
At present, the three major communication operators have entered the 5G time. In 2020, 5G will be commercialized, which means that there are various terminal products entering the market, and the research and development, testing and production currently left to the industrial chain are only one and a half years. So what are the difficulties and bottlenecks in the current 5G technology in the pilot process?
Located in Shenzhen Xili Zhongxing Park, technicians are conducting tests on the 5G pilot rate. Relevant personnel said that the higher the frequency band and the lower the penetration, the higher the frequency characteristics of 5G, requiring operators to pay attention to the indoor penetration problem, the next step of the operator's networking solution, and how the 4G network and 5G network can smoothly interact with each other. Operation, technical convergence is in urgent need of breakthrough.
It is reported that a number of operators have announced that they will deploy a 5G test network supporting 5G commercial scenarios on the field test and conduct network testing. The test content includes the coverage capability, strength of the 5G signal, handover between base stations, and interoperability between the 4G and 5G core networks. Different test services are provided for the development plans of different cities.
According to the "China 5G Industry Development Prospects and Industry Chain Investment Opportunity Analysis Report", in the early stage of 5G commercialization, the equipment manufacturer's revenue brought by network equipment investment will become the main source of 5G direct economic output. It is estimated that the total revenue of network equipment and terminal equipment will reach about 450 billion yuan in 2020, accounting for 94% of the total direct economic output. How will network equipment manufacturers seize these opportunities?
In June of this year, the introduction of the 5G international standard was regarded as the 5G “broken shell”, marking the official launch of the first truly complete international 5G standard. The freezing of the SA independent networking solution means that the mobile terminal equipment based on the 5G network can start the R&D production test under the unified standard. It is reported that commercial terminals based on 5G chips will be available in 2019, and 5G mobile phone applications require basic technical support. In the second half of 2019, ZTE Mobile will release 5G commercial mobile terminals. ZTE's 5G terminal solution will be matched in commercial R&D. The specific time of listing of ABCO will match the 5G network commercialization of the world's top operators.
The three scenarios of 5G services correspond to three core performance indicators: bandwidth, delay, and number of connections. These three requirements have a large level of improvement compared to 4G. In order to meet these requirements, the team developed and adopted a large number of new ones. technology. In the first half of this year, ZTE developed a variety of 5G devices for different needs of operators. For example, a 3.5G 64-antenna 5G Massive MIMO device, as well as a 16-channel base station device, will be developed for new models for the recent spectrum re-division. In addition to low-frequency equipment, microwave high-frequency equipment such as 28G and 39G have also been developed. Prepare for the upcoming 5G business.
