During this period of time, news of 5G mobile phones followed one after another. Xiaomi, OPPO, and vivo all showed relevant results. The test models they showed were different, and the ways to achieve 5G communication were also different. But judging from the pictures released by everyone, these mobile phones capable of 5G communication already have the same slim appearance as commercial models, and are infinitely close to commercial standards.
Let's take a look at what stage these brands have progressed. First of all, vivo has built a 5G mobile phone based on the latest flagship vivo NEX. With this mobile phone, vivo has basically completed the software and hardware development of 5G mobile phones.
OPPO officially announced that it has successfully completed the 5G signaling and data link connection based on commercially available mobile phones. This connection is realized using a 5G mobile phone developed based on OPPO R15.
Xiaomi said that Xiaomi mobile phones have successfully opened up 5G signaling and data link connections, laying a solid foundation for the official launch of 5G mobile phones next year. Although Xiaomi has not announced the specific news of this phone, it can be speculated that this is based on the upcoming Xiaomi MIX 3.
Mature commercial design Snapdragon X50 is the hero behind
These three publicly displayed 5G mobile phones are all from the most popular domestic brands. They have a common design feature, that is, the appearance design is almost the same as the current mainstream solution, at least on the screen. All three mobile phones use today's mature full-screen design, with very good visual effects, and are fully capable of entering the market.
These phones have one thing in common, that is, they use the same Qualcomm Snapdragon X50 modem. Speaking of this 5G modem, we are no stranger. Qualcomm took out the Snapdragon X50 modem product as early as October 2017, and then in many 5G interconnection tests conducted by operators and equipment, it also used a large number of test models equipped with Snapdragon X50. After all-round tests at the 5G level, it is now the most mature 5G chip product.
Qualcomm Snapdragon X50 is specially designed for 5G mobile phones. The Snapdragon X50 modem can provide multi-mode 4G/5G connection function through dual connections. It supports Sub-6GHz and 28GHz millimeter wave frequency bands. The downlink speed can reach 5Gbps, and the actual connection speed can be Reach more than ten times that of 4G network. At the same time, the Snapdragon X50 modem has comprehensive support for the two networking modes of 5G SA and 5G NSA, and conforms to the 3GPP standard.
The Snapdragon X50 can support 2G/3G/4G/5G multi-mode functions through a single chip, and it also integrates support for the Gigabit LTE function that Qualcomm is leading. Gigabit LTE network is an important part of the transition to 5G. It can take on the shortcomings of insufficient coverage in the initial stage of 5G. In the LTE network environment, providing a network environment that is not far behind the 5G experience is an important pillar of the initial 5G experience.
The design of 5G mobile phones is very different from 4G. 5G, which uses high-frequency bands for communication, is very different from 4G communication in antenna design. In addition, the design of signal amplifiers and radio frequency components to be used in 5G communications is also much more complicated than that of 4G. It is very difficult to design a 5G mobile phone that can be sold to users.
Although mobile phone manufacturers have already started the research and development of 5G mobile phones, the difficulty of designing 5G mobile phones is beyond imagination. If mobile phone manufacturers alone develop themselves, they may not be able to keep up with the time node of 2019. After all, 19 years are likely to become 5G mobile phones. The first year of commercial use.
5G mobile phone technology is the key Qualcomm accelerates the landing of 5G mobile phones
Several mobile phone brands such as Xiaomi, OPPO, and vivo have made it clear that they will launch 5G mobile phone products in 2019. They can build 5G mobile phones so quickly, and they cannot do without the support of many technology suppliers. Qualcomm is the most important one. Part of it.
In the design of 5G mobile phones, Qualcomm's biggest help for mobile phone manufacturers is the support of 5G communication modules. Qualcomm has integrated a series of necessary communication components such as antenna, signal amplification, signal transmission and reception required for 5G communication into a very sophisticated module. Mobile phone manufacturers only need to use this module and the corresponding modem chip. It will be able to complete the deployment of communications. In other words, Qualcomm has transferred the communication technology and internal deployment design difficulties of mobile phone manufacturers that need to be developed by mobile phone manufacturers, and transferred to itself, using its strong technical strength, so that mobile phone manufacturers can skip this step and devote more energy to The optimization of the functions and experience of the phone itself saves a lot of development time.
If you think about it, this approach of Qualcomm is the most efficient approach. Both technology suppliers and mobile phone manufacturers are doing what they do best, and the cooperation between the two parties is bound to be twice the result with half the effort. 5G mobile phones can be launched as scheduled in 2019, and the cooperation between Qualcomm and mobile phone brands is crucial.
5G pilot program helps domestic brands to improve their competitiveness
Qualcomm actually established this kind of 5G mobile phone research and development as early as January 2018. The 5G pilot program has joined hands with the most well-known mobile phone brands in China, such as Xiaomi, OPPO, vivo, Lenovo, and ZTE, to help them quickly launch 5G mobile phones. Products, improve product quality, and enable it to be sufficiently competitive in the international market.
The 5G mobile phone market will inevitably break the current pattern of 4G mobile phones. Faced with such a broad emerging mobile phone market, if we can take the lead in launching mature 5G mobile phone products, we will be the first to gain users.
During the transition from 3G to 4G, the mobile phone market experienced a large-scale growth. In 2015, after the Ministry of Industry and Information Technology fully issued 4G licenses, 4G mobile phones experienced a spurt of growth. 4G mobile phones accounted for 21.4% of the previous year, and took 77.9% of the entire domestic market. Technological progress has resulted in enhanced experience, which is the most important driving force for users to upgrade. 5G will also show such a situation.
Different from the 4G era, in the upcoming 5G era, Chinese mobile phone brands have more say in the global mobile phone market and are gradually threatening Apple and Samsung. Even in the 5G era, Chinese mobile phone brands are expected to lead the 5G market. Many of the 5G mobile phones currently exposed are from Chinese mobile phone brands. Chinese brands are full of interest in the creation of 5G mobile phones, and they are also an important opportunity for Chinese mobile phones to expand into the global market.
Looking forward to the 5G mobile phone market in 2019, you can try
In addition, in the recent 5G mobile phones on display, we seem to have found some clues about 5G mobile phones in 2019. It is especially worthy of the attention of users who wish to try 5G in 2019.
From the pictures released by Xiaomi and OPPO, we can clearly see that the 5G NSA non-independent networking method is used. The communication uses the 5G NR n78 frequency range with a bandwidth of 20MHz. The use is called 5G Best Frequency band 3.5GHz communication frequency. This frequency band is considered by the industry to be the highest quality frequency band that was first deployed in 5G. It belongs to the lower frequency Sub-6GHz frequency band in 5G communications and has good signal coverage and transmission speed. The 5G mobile phone test shown by vivo also uses the same frequency band settings.
As for the high-frequency millimeter wave frequency band in 5G communication, the mobile phone manufacturers did not demonstrate this aspect this time. It seems that everyone is focusing on the debugging of the Sub-6GHz frequency band. However, we must explain that the delay of the millimeter wave frequency band is not due to technical limitations, but that domestic operators will definitely take the lead in deploying the Sub-6GHz frequency band in 2019. Mobile phone manufacturers must first estimate the experience in this area. Millimeter wave technology is no longer a problem. The QTM052 millimeter wave antenna module launched by Qualcomm some time ago has perfectly solved the problem of using millimeter wave technology in mobile phones. It can deploy up to four modules in the mobile phone. It is flexibly deployed on the four sides of the mobile phone to fully ensure that the signal transmission and reception is not affected by millimeter wave susceptible interference.
A complete 5G mobile phone must fully support 5G communication technology. In the 5G mobile phones launched in 2019, they may not be able to provide complete functional support. After all, the operator's network deployment has not yet been completed at this time. 5G mobile phones in 2019 Perhaps more is to allow a small number of users to try something new. However, mobile phone manufacturers backed by the giant Qualcomm will certainly be able to launch mature and excellent 5G mobile phones in the future.
Nowadays, the function and appearance of mobile phones are similar, but the charging interface is not unified. The Android camp has Micro USB and Type-C ports, while the iPhone camp has Lightning. Different charging ports use different charging cables, which is very unfriendly for users who often need to use multiple phones. To solve this awkward situation, the three-in-one data cable was born. What is the three-in-one data cable? Three-in-one data cable means that one data cable includes Micro Usb Cable, USB Cable For Iphone and Usb Cable Type C. So one data cable can be used by all mobile phones.
Three-in-one data line is also known as multifunctional data cable. In the original data cable, the combination scheme is added, and the combination PCB is configured, which can support a variety of equipment and avoid the trouble of frequently looking for data line. It combines Lightning, a 30-pin port, and a Micro USB port, and is compatible with multiple devices. It can connect to any smartphone or tablet, including iPhone, iPad, Samsung, etc.
From the technical point of view, the three-in-one data cable does have a strong advantage. With continuous development and improvement, three in one data cable products in the original data cable appearance with woven cloth, will also add a light color on the three in one data cable, so that the data cable function is stronger and more exquisite, more and more people accept and buy. In the era of big data,the 3 In 1 Usb Cable can be said to have deeply affected our work and life. We believe that with the technical development of 3-in-1 mobile phone data cable, it will bring us more convenient transmission experience.
