Xiaomi, OPPO, and vivo rush to "take the lead" and 5G chip maturity becomes a key factor
Now, it is at the final juncture before 5G commercialization, and the industry is accelerating its pace to promote the maturity of 5G as soon as possible.
Recently, Ericsson and Qualcomm have cooperated to complete a 5G data call in the 39GHz frequency band that complies with 3GPP standards, further proving that 5G technology is ready for commercial use. Almost at the same time, Huawei successfully opened up First Call (data service) based on the 3GPP R15 standard in Huairou, Beijing. There is no doubt that these events are of great significance in the 5G promotion process.
On the other end, mobile phone manufacturers are also "unwilling to be lonely." OPPO, vivo, Xiaomi and other manufacturers recently "coincidentally" disclosed the latest developments in 5G mobile phones, and said they are expected to be the first to launch commercial 5G mobile phones.
The industry chain is constantly advancing 5G towards maturity.
In December last year, the 5G standard for non-independent networking was frozen. Two months later, in February of this year, Huawei and Vodafone completed the world's first 5G call using non-independent networking standards and the Sub6 GHz frequency band. "In early February this year, Nokia, Qualcomm and Verizon also passed through the New Jersey laboratory, and KT and Verizon also made video calls with Minneapolis in the United States in Seoul, South Korea." Verizon academician Dr. Ye Ouyang said.
The downlink data call completed by Ericsson was made in the laboratory in Kista, Sweden, using 39GHz millimeter wave and 5G NR Air 5331 base station and a test equipment using Qualcomm Snapdragon X50 5G modem and wireless sub-module. Ericsson and Qualcomm believe that this cooperation will pave the way for the launch of infrastructure, smartphones and other mobile devices that meet the 5G NR standard. The First Call (data service) that Huawei has opened up means the official opening of the end-to-end 5G commercial system test site under the SA independent networking architecture in China's 5G technology research and development test.
Mobile phone manufacturers want to be the "number one player"Chip vendors and equipment vendors are racing against time for 5G commercial use, and mobile phone manufacturers are also vying for the first launch of 5G mobile phones.
Recently, OPPO, vivo and Xiaomi have announced new developments in their own 5G mobile phones. First, OPPO announced that it had completed the 5G signaling and data link connection based on commercially available mobile phones. Then vivo announced that it had initially completed the development of commercial 5G smart phone software and hardware, and will launch 5G pre-commercial mobile phones in 2019. After that, Xiaomi mobile phone also announced the opening of 5G signaling and data link connection, and it is expected to officially launch 5G mobile phones next year.
The connection of signaling and data links is the basis for ensuring reliable communication functions of 5G mobile phones, and it is also an important step for 5G smart phones to mature. "Simply understand that opening up 5G signaling and data links is for equipment vendors and operators to do a good job of the network and interfaces so that mobile phones can connect. 5G networks are not yet mature, and now 5G mobile phones can only run in backward compatible 4G mode. In the 5G pilot area, experience the speed of 5G.†Li Yangyuan, the founder of the chip company Mindray Micro Company in Suzhou, told the IT Times that the most powerful first and mass-produced 5G mobile phone should be Huawei. Huawei has its own 5G baseband and network solutions. Program. Huawei's rotating CEO Xu Zhijun has also made it clear that it will launch 5G-enabled smartphones before June 2019.
The chip battle behindWhether 5G mobile phones can be launched depends on the maturity and mass production of 5G chips.
In August of this year, Qualcomm announced that it would launch a flagship mobile platform on a system-on-chip (SoC) using a 7-nanometer process technology that can be paired with the Snapdragon X50 5G modem. Qualcomm's expectation for it is to become the first mobile platform that supports 5G functions. "Qualcomm's first batch of 5G chips is limited in number. If mobile phone manufacturers can only make first launches but not mass production, consumers can only watch and can't buy them, what's the point?" A person in the communications industry thinks.
The 5G baseband market is also undergoing tremendous changes, with the exception of Qualcomm, Huawei and Intel.
In September last year, Intel released the third-generation Intel 5G mobile test platform, which can help operators and equipment vendors conduct rapid field tests and interoperability tests on 5G networks and equipment. "In the fourth quarter of last year, it has invested and cooperated. During the joint test of partners." Intel related personnel told a reporter of "IT Times". In November last year, Intel launched a family of multi-mode commercial modems supporting 5G New Radio (5G NR)-Intel XMM 8000 series, which will be used in commercial terminal equipment in mid-2019. "Currently, cooperation with terminal manufacturers is progressing smoothly, but it is not convenient to disclose specific customer information." The above-mentioned person said.
Intel, which lacks sufficient courage in the 4G era, is now an active participant in the 5G field. If Intel can mass produce 5G chips faster, domestic mobile phone manufacturers may also switch to Intel's embrace.
High base station density and high cost are also challengesWhether 5G can be commercialized depends on whether the network side is mature enough in addition to the terminal side.
"5G uses high frequency and high density of sites. In the future, my country will need about 5 million base station sites to achieve good coverage of 5G. Now there are 2 million base station sites in stock, and 3 million new base station sites need to be added. An investment of 300 billion yuan.†Gao Buwen, deputy general manager of China Tower, said recently that 5G faces many challenges, such as difficulty in site selection of base stations, large investment, long construction period, and impact on urban landscape and landscape. "We have also come up with solutions. One is to use urban lighting poles and other facilities for 5G base station construction, which is expected to be about 10 to 12 million in the future; the other is to control the scale of new base stations to greatly reduce the difficulty of 5G deployment. "Gao Buwen said. Now the three operators have carried out 5G scale trials in full swing to expand the scope of 5G pilot cities.
According to the 5G commercial timetables of the three operators, 5G can be pre-commercialized in 2019, and will be officially commercialized in 2020. At present, China's 5G technology research and development test has entered the third stage, which is also a key step before 5G is commercialized, and it is planned to be completed within this year.
