5G chip’s “Spring and Autumn Five”


Editor’s Note: This article comes from the “Finance” magazine APP, Wen | Wu Junning, editor 丨 Mark, 36 氪 authorized to release.In the spring and autumn period of Chinese history, with the weakness of the Zhou royal family, some powerful vassal states formed a long-term and horizontal relationship, forming a specific historical product of the Spring and Autumn Period – the Spring and Autumn Five.In today’s wireless communication baseband chip field, because 5G is different from the previous 3G and 4G standards, it is not only to pursue higher data throughput, but also to have greater network capacity and better service quality.Therefore, the R&D and design of the baseband chip will be more complicated. Only the manufacturers with strong R&D strength and strong technical accumulation can stand the test of the market.The 5G chip is complicated because it needs to be compatible with all previous frequency bands and formats.In the 4G era, what everyone often hears is “five-mode seventeen-frequency”. If you want to support China Telecom’s 3G network, it is “six-mode full Netcom.”In the 5G era, it is necessary to increase to “seven-mode full Netcom”, and the complexity of the 5G chip can be seen.Therefore, in the 5G era, there are only a handful of manufacturers that can launch 5G mobile phone baseband chips. Only Huawei/MediaTek/Qualcomm/Exhibition/Samsung five are the “Spring and Autumn Five” of a 5G chip.In the history of Qi Gonggong, he adopted Guan Zhong’s opinion, played the banner of “respecting the king and blasphemy”, united other princes, attacked the mountains in the north, and chu in the south, established prestige among the princes, and called the princes to meet even the Zhou royal family.People participated in the first hegemony officially recognized by the Zhou royal family during the Spring and Autumn Period.This is not Qualcomm.Starting from the release of the first Qualcomm processor-based smartphone in 2011, coupled with the rapid development of China Mobile Internet, Qualcomm has become increasingly popular in China’s mobile terminal processor field. Almost all domestic mobile phone manufacturers have adoptedThe first mobile phone based on Qualcomm’s flagship processor was proud of it. It is the well-known “overlord” in the field of mobile phone processors, and even the models equipped with Qualcomm’s low-end and mid-range processors are more accessible to consumers than other manufacturers.Recognition.In the 5G era, Qualcomm is also in a leading position. The Qualcomm X55 baseband processor is one of the most advanced 5G solutions to date. Multimode supports 2G to 5G, covering all major frequency bands in all regions of the world, and achieving a maximum 5G rate of 7Gbps.The Xiaolong X55 baseband is manufactured using the most advanced 7nm process. It can fully support 2G, 3G, 4G and 5G in a single chip. The 5G part fully supports the millimeter wave and below 6GHz frequency band, TDD time division duplex and FDD frequency division duplex mode., as well as SA independent networking and NSA non-independent networking mode.After finishing the recognized “hegemony” Qi Gonggong Qualcomm, the next step is to talk about Jin Wengong, who is good at making friends and will be in the world. Jin is located in the land of Qi, Chu and Qin. If you can’t handle the relationship with AIA.It is extremely difficult to preserve its own safety. In the history, Jin Wengong once invited Zhou Yuwang, and summoned Qi, Song and other countries to practice the soil and princes. The history said: “Practice the League,” and then become another in the Spring and Autumn Period.A hegemon.Backed by Ziguang Group’s Spreadtrum, the mobile phone processor market has long been tempered by Qualcomm, MediaTek and other manufacturers. In the domestic market, it has been relatively embarrassing. It is not as good as Qualcomm. It is not as good as MediaTek, but Spreadtrum can make it to Samsung, Xiaomi and other manufacturers.Launched models equipped with their own processors for specific markets, and exported to markets such as India.Thanks to the long-term accumulation of Spreadtrum and RADICO in the RF field, Spreadtrum launched the 12G baseband chip Violet Ivyium 510 based on TSMC’s 12nm in the first 5G years. Although the performance cannot be compared with Qualcomm and Huawei, it also supports many.Key technology of 5G, single chip supports 2G/3G/4G/5G multiple communication modes, conforms to the latest 3GPP R15 standard specification, supports Sub-6GHz frequency band, 100MHz bandwidth, is a high integration, high performance, low power consumption5G baseband chip.Both the 5G SA independent networking and the NSA non-independent networking are supported.If you have a little understanding of the history of China, you know that the Qin State has defeated other vassal states after the Spring and Autumn Period and the other vassal states, and created the Qin Empire of the Great Unification. Qin Mugong in the Spring and Autumn Period is also a Spring and Autumn Five tyrant highly recognized by historians.One, because it is located in the west of the letter valley, the terrain is steep, easy to defend and difficult to attack, Qin Mugong, who dominated Xiqiao, has opened up more than a thousand years of land, laying the foundation for the future Qin unified China.However, this time the metaphor of Huawei became Qin Mugong, not implying that its follow-up will unify the 5G chip market, but because of the self-produced and self-selling model of Huawei’s baseband chips, it is very similar to Qin.Moreover, Qin Guo later adopted the strategy of far-reaching near-attack, and also sold Renowned 5G technology to European and American countries instead of domestic mobile phone manufacturers.Huawei’s Balong 5000 is a single-chip multi-mode 5G module that can implement 2G, 3G, 4G and 5G network standards in a single chip, effectively reducing the delay and power consumption caused by data exchange between multiple modes.And it is the first to support the joint network mode of NSA and SA in the world, and support FDD and TDD to achieve full-band use.At the same time, it achieves the industry’s benchmark 5G peak download rate, achieving 4.6Gbps in the Sub-6GHz (low frequency band, 5G main frequency band) band, and 6.5Gbps in the millimeter wave band, which is 10 times the 4G LTE experience rate.Like Qin Mugong, who is in charge of the letter valley, another spring and autumn five-master Chu Zhuang Wang also occupied a geographical advantage.The king of Chuzhuang in history was once subject to the suppression of Qi Yugong and stopped to enter the Central Plains, but it annexed some small countries, and the national strength could not be underestimated.This is very similar to Samsung’s market and status in China. As the first foreign company to enter the Chinese market, Samsung not only sells complete products, but also has mobile phone baseband processors, but is subject to Qualcomm’s strong domestic market and is equipped with Samsung.The mobile phone, in addition to Samsung itself, is Meizu.In terms of 5G chips, Samsung Exynos Modem 5100 chip is built with 10nm LPP technology, supports Sub 6GHz mid-low frequency and mmWave high frequency, and is backward compatible with 2G/3G/4G, including but not limited to GSM, CDMA, WCDMA, TD-SCDMA, HSPA., 4G LTE, etc.The Exynos Modem 5100 can achieve a download rate of up to 2 Gbps at Sub 6 GHz, a 6 Gbps download rate in the millimeter wave band, and a 4 Gbps speed to 1.6 Gbps.Coupled with the newly released integrated 5G baseband processor Exynos 980, its ambition to seize the 5G chip market is not to be underestimated.In fact, when it comes to here, there is only one Song Gonggong left in the Spring and Autumn Five, and only the MediaTek is able to launch the 5G chip.Song Songgong in history is the spokesperson of the Spring and Autumn Annals. This is because after Qi Qigong’s death, Qi’s domestic chaos led Song Yigong to lead the four countries of Weiguo, Cao Guo and Shuguo.Therefore, the fame is set off.In the field of mobile phone baseband processors, MediaTek has always been a unique presence.Because the turnkey project is doing a good job, the former cottage machines all use MediaTek’s processor. Any mobile phone can be imitated, and Nokia is the manufacturer that suffers from it. Huaqiang North has benefited a lot.Later, when the domestic Android mobile phone boomed and the cottage machine disappeared, MediaTek tried to get rid of the reputation of the low-end processor, but because the marriage of Xiaomi was only used on the low-end model red rice mobile phone, it still could not be connected with Qualcomm and Samsung.Confronting, even when Huawei is about to stabilize the high-end processor field, MediaTek is still in the low-end market.This time, MediaTek launched the Helio M70 5G, which uses 7nm technology and is fully compatible with 4/3/2G. The maximum download speed is 4.7Gbps and the upload speed is 2.5Gbps. It supports SA and NSA dual modes.Full support for millimeter wave and below 6GHz frequency band, TDD time division duplex and FDD frequency division duplex mode.Its largest market is still in the domestic low-end products.As the most popular chip market, there is a big gap between 5G chips and artificial intelligence processors.In the field of artificial intelligence chips, although the AI ​​chips in the world show the two oligarchs of NVIDIA and Intel, but because of the main battlefield of China’s artificial intelligence application and the rapid development of Internet companies, the overall AI chip presents a “hundred flowers and hundreds of schools of contention”The pattern.However, in the field of 5G chips, this will no longer exist. On the one hand, the technical barriers of 5G chips are high, and there is a need for years of technical accumulation. At the same time, the AI ​​chips are close to the downstream and are oriented by application scenarios. 5GThe chip is more to provide support for Internet applications, and it is more inclined to the upstream. This has formed the era of the big princes of the Spring and Autumn Period. Each family has its own market and strategy. Who can win the Central Plains?It is hard to say in the 5G era that we can only wait until 6G to make another technological innovation to see which one is left behind and which is new.The header image is from pexels.
