China's first 5G phone dialed! ZTE Corporation stated on the official microblog that it recently opened a 5G first call based on the 3GPP R15 standard and officially opened an end-to-end 5G commercial system scale outfield site, which further accelerated the 5G commercial process. The 5G era really is coming?
ZTE and China Mobile opened the first 5G phone. Recently, ZTE and China Mobile Guangdong successfully opened a phone based on 3GPP R15 standard in Guangzhou and formally launched an end-to-end 5G commercial system scale outfield site.
ZTE said that this move further accelerated the 5G commercial process and opened a new chapter in the era of the Internet of Everything.
China Mobile plans to launch 5G scale tests in multiple cities this year, and Guangzhou is one of the 5G pilot cities. In June 2017, Joint ZTE Corporation opened the first domestic 5G pre-commercial base station. According to reports, the 5G phone was opened up on the basis of ZTE's global 5G end-to-end system for commercial use, and complied with the latest 3GPP R15 standard. 3GPP R15 is the first version of the 5G standard, and the complete standard 3GPP R16 will come out in June this year.
In addition to China Mobile, ZTE is also working with multiple operators worldwide to promote the verification and testing of 5G technologies and accelerate commercial deployment.
Up to now, ZTE has signed 5G strategic cooperation agreements with more than 20 operators including China Telecom, China Unicom, Telefonica, Italy Wind Tre, Belgium Telenet, Veon, Belarus velcom, Malaysia U Mobile, South Korea KT, and Ooredoo. Orientation of technical and industrial cooperation.
China’s communications technology has experienced the synchronization of the 2G era and the participation of the 3G era in the 4G era. In the 5G era, the industry generally believes that China has successfully entered the first echelon and has taken the lead in the formulation of 5G bearer standards and the 5G industry chain. .
According to the working arrangements of relevant international standards organizations, the first 5G international standard version will be officially released in June 2018. It is worth noting that the planned 5G standard will no longer have multiple technical versions, but will form the only standard for unified integration.
Wang Zhiqin, vice president of the China Academy of Information and Communication Technology, said that after the first version of the 5G international standard is released, it will be a good thing for the development of China's 5G industry and information industry.
According to a research report released by Essence Securities, China and the United States have seen a clear "negative growth" trend in the 4G era in terms of the industry chain's investment strength and discourse power. U.S. operators’ investment in the communications industry is gradually being overtaken by U.S. Internet ISPs (service providers), and the United States’ influence on the development of global telecommunications is becoming weaker. However, China has achieved "2G start, 3G catch-up, 4G synchronization" in terms of standard technology, commercial maturity and market application, and will achieve "5G surpassing."
Meng Pu, chairman of Qualcomm China, believes that in the 5G era, China will be a very important participant and promoter. China's 5G development will certainly affect the global 5G process. The Chinese government has placed 5G at the height of its national strategy, giving strong support to the development of 5G and fully deploying it. Facing the future, China and the world are on the same starting line.
Driving a number of trillion-level emerging industriesPeople in the industry generally believe that once the 5G network is officially commercialized, apart from making the communications industry enter a new phase of development, it will also bring in a number of trillion-level emerging industries.
The Qualcomm report predicts that by 2035, 5G will create 12.3 trillion US dollars of economic output globally. It is expected that 5G will contribute to global GDP growth from 2020 to 2035, equivalent to economies of the same size as India.
At present, many countries and regions attach great importance to the commercial use of 5G. The United States, the European Union, South Korea, Japan, and China all plan to start commercial deployment of 5G networks in the second half of 2019 and formally commercialize them in 2020. With the announcement of 5G international standards, global 5G industry competition will become increasingly fierce.
From the viewpoint of the 5G industry chain, the upstream of the industry includes communication equipment manufacturers such as base stations, antennas, optical cables, chips, and radio frequency devices, while the middle reaches are major telecommunications operators, while ordinary users directly experience various terminal equipment vendors such as mobile phones. In the face of the big cake of 5G, all parties are ready to go and the new applications to be detonated by 5G are also highly anticipated.
Several market organizations predict that the typical Internet of Things subdivided industries such as the Internet of Vehicles, big data, cloud computing, smart homes and drones are quite mature at the technology and application level, but the communication capabilities of the existing 4G networks are greatly limited. Industrial development. With the official commercial use of 5G, the network problem will be solved, the above services will be successfully applied, and related industries will usher in a period of rapid development.
Incremental Encoder is commonly used, and Absolute Encoder is used if there are strict requirements on position and zero position. Servo system should be analyzed in detail, depending on the application situation. Commonly used incremental encoder for speed measurement, which can be used for infinite accumulation measurement; Absolute encoder is used for position measurement, and the position is unique (single or multiple turns). Finally, it depends on the application situation and the purpose and requirements to be realized.
