A true and false 5G whipped up during the MWC19 Shanghai exhibitionMobile phone"The wind just subsided, Samsung with its "real" 5G flagship Galaxy Note10 + 5G strong landing in China.
Before the launch of the flagship machine, Samsung also held a special media communication meeting, which refuted the “true and false 5G mobile phone” speech from the technical level, and emphasized that both NSA and SA are 5G. Currently, the SA mobile phone is SA0.1, which is not supported. Double connection is a premature baby. ”
"NSA is the starting point, SA is the future." Zhang Daijun believes that for operators, the 5G prospects are attractive and realistic, and the current NSA commercialization is better than SA. "NSA and SA are the same roots, and the reason why it is too urgent" is not desirable.
In terms of 5G, Samsung has always been serious. "If you let the wind come down, you can still smash it." Just this time, can Samsung use the wind of 5G to skyrocket? Can the Chinese market pay for it?
Samsung rises with 5G?
At the press conference, Quan Guixian, president of Samsung Electronics Greater China, reiterated many times that "Samsung will rise with 5G!"
What gave Samsung courage?
Zhang Daijun, dean of the Samsung China Research Institute, mentioned that as early as 2009, Samsung began research on 5G networks. After 10 years of painstaking research, now the depth of the entire industry chain, everything is in order. ”
In May 2013, Samsung developed the millimeter-wave Ka-band (26.5-40 GHz) adaptive array transceiver technology for cellular communication, which is the core of 5G mobile communication technology, and its data transmission speed is faster than that of 4G LTE network. hundred times.
In October 2014, Samsung announced that its 5G transmission speed reached 7.5Gbps in a fixed scenario, 30 times faster than 4G LTE. Meanwhile, in the mobile scene, the speed of the vehicle exceeds 100km/h, Samsung's 5G network has always been Stay connected and transfer speeds up to 1.2Gbps.
In August 2018, Samsung introduced the baseband chip for 5G mobile communications: Exynos Modem 5100. It uses a 10nm LPP process to achieve a download rate of up to 2Gbps in the Sub 6GHz band and 6Gbps in the millimeter wave band.
In April 2019, the world's first commercial 5G mobile phone, the Samsung Galaxy S10 5G, was officially launched in South Korea.
“Samsung started the 5G millimeter wave test in 2013 and is the first manufacturer to start the millimeter wave test in the world. In 2017, Samsung launched the commercialization test of millimeter wave fixed wireless access, and launched the world’s first 5G commercialization in 2018. Base station. In 2019, the world's first 5G commercial terminal S10+ 5G was officially launched.” Zhang Daijun pointed out, “We have a 5G millimeter wave measured download rate of 1.9Gbps with Verizon, and 5G millimeter wave commercial city will expand from 2 to this year. 20."
Zhang Daijun predicted that China's millimeter wave should start commercial use in 2021-2022, and Samsung has already made preparations.
Not only that, Samsung has more than 1,400 5G standard patents in the 5G patent reserve. According to Samsung's disclosure, Samsung plans to invest 22 billion US dollars in 5G and artificial intelligence and auto parts and other related fields, and expects to occupy 20% market share in 5G field by 2020.
Zhang Daijun said that Samsung is one of the few manufacturers in the world with 5G end-to-end solutions. "10 years of 5G research and development, dare to be the best in the world."
NSA or SA, Samsung is in the chest
The MWC19 Shanghai exhibition has a "true and false 5G mobile phone" style, which is misleading to consumers. From a technical point of view, NSA and SA are both true 5G, which is an indisputable fact.
"The current SA is immature. Currently, the SA mobile phone is SA0.1 and does not support dual connectivity." Zhang Daijun pointed out, "This is the reality. The mMTC and URLLC application scenarios are only supported in Rel-16; the new application scenario is special. Terminals, new application scenarios require new physical layer technologies."
"So, Rel-15's NSA mobile phone and SA0.1 mobile phone are not very good at supporting new application scenarios (mMTC, URLLC)." Zhang Daijun particularly stressed, "China MobileThe SA mobile phone mentioned by the director Yang Jie is the R16 version of the SA mobile phone. Currently, the R15 version of the SA mobile phone is useless for solving industrial applications. ”
"NSA is the starting point, SA is the future." Zhang Daijun believes that for operators, the 5G prospects are attractive and realistic. At present, NSA is better commercialized than SA. At present, the SA standard is not ready, and the industry is not ready. ”
The current NSA performance is not inferior to SA in terms of the connection requirements of ultra-high-speed people who meet the toC end. "China's ICT test results show that NSA downlink speed is stronger than SA; in addition, SK test results show that NSA dual connectivity can achieve twice the download speed of SA."
"At present, 42 operators that announce 5G commercial use are all NSAs, and SA commercials are still 0; and the 5G R16 version of the standard will be launched in the first half of next year at the earliest, and the industry application breakthrough will be as fast as 2024 or In 2025. In addition, operators must face the NSA's influx and problems, so the NSA is unable to circumvent the past."
"SA, Samsung is also in the chest!" Zhang Daijun revealed, "Samsung and SKT have successfully completed the 5G SA network test. Samsung Semiconductor will support SA at the end of this year, Samsung terminals will support SA early next year.
In addition, Zhang Daijun also focused on 5G mobile phone terminal users. "NSA now supports EMBB's ultra-high-speed dual connectivity. Now SA does not support it; in terms of standard maturity, NSA is now 1.0, SA is only 0.1; in terms of download speed, the current NSA is 1.7Gbps, and the current SA is 1.5Gbps."
