Shenzhen has taken the lead in realizing 5g independent network coverage in China and Shenzhen is the first to enter the 5g era, the mayor of Shenzhen announced at a press conference on the 17th. Huang Haifeng, a senior independent analyst in the communications industry, believes that it is not too much to call Shenzhen “the world’s first 5g city” from the aspects of technology application, network construction quantity and quality. Jiang junmu, the chief reporter and senior technology commentator, said that the external adverse factors such as “neck sticking” mainly affect Huawei in the terminal field, and the impact of 5g network construction and application is limited.
In the official announcement of Shenzhen, “independent networking” is the key word mentioned. According to public reports, 5g network architecture mainly includes two ways: independent Networking (SA) and non independent Networking (NSA). Non independent networking is to upgrade the existing 4G network, add 5g equipment and share the core network; independent networking is to build a complete set of 5g network, including base station and core network And the cost is higher. However, independent networking can provide better 5g services and achieve more functions, so independent networking has become the ultimate goal of domestic operators.
According to an official from the Shenzhen Municipal Bureau of industry and information technology, 45000 5g base stations have been built in Shenzhen by the end of July this year. At present, the density of 5g base stations in Shenzhen ranks first in China, the total number of necessary patents for 5g standards is the world’s leader, and the scale of 5g industry and the shipment of 5g base stations and terminals in Shenzhen ranks first in the world.
Shenzhen took the lead in completing the 5g independent network coverage, which also made it the “5g world’s first city”. Huang Haifeng told reporters that to become the “first city”, it needs to be in the lead in technology application, network construction quantity and quality, industrial ecology, user development, application exploration, etc. at present, Shenzhen has overcome many challenges and is in the forefront in all aspects, Therefore, this title is not excessive.
At present, when will Shenzhen announce its network coverage? Jiang junmu believes that this first represents China’s leading position in 5g: “in terms of the number of base stations, Shenzhen alone is more than any other country.” He also stressed that, on the other hand, it also reflects Huawei’s top support capability for 5g equipment deployment, which also shows that Huawei’s 5g equipment supply has not had any problems in the past period of time.
Up to now, 92 operators in the world have deployed 5g commercial networks, and the global 5g users have exceeded 100 million. In his keynote speech on the same day, Guo Ping, chairman of Huawei, once again mentioned that the current global 5g deployment will come to an end, and the next stage will focus on developing industry applications, releasing 5g dividends and achieving 5g commercial success; 3GPP R16 standard is officially frozen, which will further promote the development of 5g industry application.
Due to the restriction of the United States on Huawei’s supply chain, the impact of 5g deployment and application in the future has attracted much attention from all walks of life. Huang Haifeng told reporters that the U.S. has a certain impact on Huawei’s 5g deployment. However, Huawei is able to provide stable supplies and participate in supporting the construction of 46000 base stations in Shenzhen in just one year.
Jiang junmu believes that the main impact of external adverse factors on Huawei is in the terminal field, but the impact on 5g network construction and application is actually limited, because the demand for chips in this field is far less than that of the former. “Huawei’s 5g chip inventory does not support the global demand for 5g network construction. Moreover, even if chips with 7-nanometer technology can no longer be used in the short term, 14 nm or 28 nm can also be used After all, chips that don’t use state-of-the-art technology will mainly affect power consumption, but they can also be compensated in other ways. “
