Editor’s Note: This article comes from the WeChat public account “Luo Chao Channel” (ID: luochaotmt), the author Luo Chao channel, 36 氪 authorized to release.These days, with the launch of the Huawei Mate 30 series and the iPhone 11 launch, Huawei and Apple occupied the home of the technology circle, and all discussions about the two mobile phone companies circumvented one topic: 5G.5G is already on the string, there are many 5G mobile phones on the market. With the release of Huawei’s first 5G SoC Kirin 990 5G, Huawei’s 5G flagship and glory 5G flagship are all coming out.In the same period, Samsung released the Exynos 980 5G SoC.Kirin 990 5G and Exynos 980 both integrate 5G communication baseband with CPU, GPU, NPU and other processors, and perform better in efficiency, performance and heat dissipation. The biggest problem of 5G mobile phone is chip, now 5G mobile phone isThe hardware level is already ready.However, regarding the purchase of 5G mobile phones, the user’s judgment has diverged, and the biggest difference is the judgment of the network infrastructure.Some believe that the 5G network construction is not perfect, it is too early to buy 5G mobile phones.iPhone 11 does not have 5G version, Apple CEO Cook explained to Tencent Technology: “At present (5G) is still a little ahead, we have studied the market and found that the entire market, whether it is infrastructure or chip, is not mature enough.It is not enough to launch a high-quality product.” My opinion is that Apple is lacking in core, and it is difficult to make a 5G mobile phone.In December 2013, 4G was issued in China, but Apple’s iPhone 5 released in 2012 already supported 4G early (National Bank version does not support). In 2013, iPhone 5s started to support 4G.Was the 4G network ready at the time?Is the 4G industry mature?No.The other part believes that the popularity of 5G networks is faster than we expected.Now you don’t need to change your 4G mobile phone to a 5G mobile phone, but if you are going to change the machine, you must consider 5G.As an optimist, I hold this view.China Mobile has built more than 20,000 5G base stations in 52 key cities across the country. At the same time, in order to allow more customers to perceive 5G networks through 5G experience halls, 5G networks have been built in more than 300 cities across the country, and it is expected to exceed 2019.50 cities achieve 5G commercial services.In 2020, the network coverage will be further expanded to provide 5G commercial services in all cities above the prefecture level. 5G will be available in core cities next year.We should not only consider the situation today when buying a mobile phone. The life cycle of a mobile phone is about 2 years. This means that today, if you change your machine, you can consider a 5G mobile phone. Otherwise, you will either use 5G or change it after one year.machine.There are indeed many users who can accept the pain for a while, but there are many reasons for not buying 5G now: unwilling to be a mouse, no need for faster internet speed, etc. This kind of consideration is equally understandable.The user base is different. Yahoo’s former president Jeff Bonfort divided consumers into technical innovators, irrational consumers, rational consumers, super-rational consumers and waiters according to different emotional characteristics.It’s easy to understand why everyone’s attitude towards 5G is so different: 1. Technology innovators: buying products is simply because the products use new technology, they are obsessed with the technology itself; 2. irrational consumers (ie early adopters)()): In order to satisfy emotional needs, irrational consumers will pay far more than the energy and cost of solving the problem itself.3, rational consumers (ie early consumer): only buy products that they think are practical and mature.They are more pragmatic and will only buy products that are cost effective.4, super-rational consumers: emotional needs are weaker, even if the products are not satisfactory, they will not save money.5. Watchers (ie followers): About 15% of the total number of people, they also have demand, but only buy products that are well-recognized.You can try to categorize and comment on 5G users in different communities, Weibo and WeChat. Basically, you can summarize them into the above five categories.Consumers who buy 5G mobile phones in 2019 should be 1 and 2 mainly plus a small part. 3. 5G mobile phones are sold well?Compared with the fact that many people like to judge with their own or the judgments of others around them, I think the data of professional organizations is more convincing.The Strategy Analytics report predicts that global 5G smartphone shipments will reach 5 million units by 2019. By 2025, global 5G smartphone shipments are expected to reach 1 billion units per year.South Korea began commercial 5G in April. As of August 5, the number of 5G users of the three operators in South Korea reached 2.01 million, the population of South Korea was 51.64 million, the penetration rate of 5G was close to 4%, and the penetration rate was faster than 4G.Therefore, I think it is meaningless to argue whether 5G mobile phones are worth buying. Different types of consumers will use money to vote in combination with their own needs and consumption habits.The key to the question is: If you buy a 5G phone, what should we pay attention to?I think the most important point is that dual-mode full Netcom should be preferred.If you don’t buy a 5G mobile phone, it’s just a sight, and you can buy it for a while, but if you don’t buy a full 5G mobile phone, it may be very troublesome.What does that mean?As a new thing, 5G consumers do not know that there are many pits inside.A few days ago, I saw a Weibo, glory president Zhao Ming forwarded an article about 5G science in Pacific Internet. “Mobile phone manufacturers have the responsibility and obligation to tell consumers that their recently purchased 5G mobile phones are now and in the future.Can local and domestic roaming use 5G? Is it local or national? This question should not be avoided, and it should not be deliberately confused. The right to know should be returned to users. Many people have spent thousands of dollars to buy 5G mobile phones.In the end, only 4G services can be used, which is suspected of deceiving consumers. Why does 5G have a full Netcom and local communication?Because 5G network is different from 4G, 5G should consider 4G backward compatibility. Now part adopts NSA non-independent networking, adopts dual connection mode, 5G NR control plane is anchored to 4G LTE, and uses 4G network EPC (packet core network)), the essence is that 5G can reuse 4G resources; SA is an independent network, everything must be rebuilt, both models have their own advantages and disadvantages, but the three major operators have stated: NSA is only a 5G commercial transitional solution,The independent networking of SA is the ultimate direction.Yang Jie, chairman of China Mobile, said at the 2019 GIT International Industry Summit that starting from January next year, there will be no new NSA mobile phones in the country. SA will be the development direction of China’s 5G, and China will transition to SA as soon as possible.Mobile customer service clearly indicates 5G users in the SMS: Under the NSA/SA hybrid network, only single-mode mobile phones supporting NSA will not be able to connect to 5G networks in only SA network locations.However, many consumers are confused about the difference between NSA/SA, too technical.The full Netcom in the 4G era refers to the network that is compatible with the different systems of the three operators. The 5G does not have this problem. The three major operators have the same standard, but the frequency bands are different, but the network has become more complicated: 2G is not yet comprehensive.Retired, 3G, 4G different standards should be compatible, 5G network has a non-independent networking solution based on 5G upgrade NSA and independent networking SA, although the three domestic operators have stated that SA is the core goal of 5G, butThe NSA will exist during the transition period. How long does this take?No one can give an answer now.Therefore, if consumers buy 5G mobile phones, they must put network compatibility first. If the mobile phone does not support SA, it is not a true full Netcom 5G mobile phone. It will appear in some cities with 5G and 5G.In other cases, this is why the Huawei Kirin 990 5G emphasizes that it is a full-range, dual-mode, full Netcom 5G chip. Based on the Huawei Mate 30 series and the Glory V30 of the Kirin 990 5G, it can connect 5G networks anywhere in the country.The competitiveness on the network will be very obvious.Of course, if you don’t mind such troubles, you can also buy a 5G mobile phone that is not really full Netcom.Just like the idea that I have been advocating: the most important thing to buy electronic products is to figure out your needs, prioritize the core, prioritize the core needs, and make budget decisions easily.For mobile phone manufacturers, there is no problem in producing 5G mobile phones that only support NSA networks. The relevant departments give network access licenses to show that such products have certain value, and there must be some users willing to accept, but must tell consumersBe clear, let me know and remind you that the users who buy 5G mobile phones are real technology innovators and early adopters. It is a KOC (key opinion users) that can affect the users around them. Their value to the brand is already very important..
