About 5G, the ten questions that the people care most about

After reading ten answers, make sure you will be the group of people who know 5 gigabytes best in the world.

Q: Can I use 5G at any time this year?

A: I'm sure it won't work this year. It's going to take a long time.

Indeed, domestic 5G progress is very fast, operators are actively conducting pilot experiments in many cities in China, and the 5G applications displayed are even more prosperous. However, ordinary users want to use 5G services anytime and anywhere, this year is definitely not a problem, waiting for a long time.

From the point of view of the difficulty of building the network, 5G is a lot more difficult, so operators can not complete the continuous coverage of 5G in the whole country in a short period of time, but will adopt the strategy of gradual coverage, starting with the first-tier cities with dense traffic. And then radiate it, which takes time. So, you may use 5G services in some and hot cities this year, but it's impossible to use 5G anytime, anywhere.

At a deeper level, there is an essential difference between 5G and 2G/3G/4G. It not only provides human-to-person communication, brings faster network speed, but also provides person-to-object, object-to-thing communication, ultra-low delay communication and mass connection. If you define "using 5G at any time" as being able to access the Internet faster at any time, it will take some time, and if you define 5G as the Internet of everything, you will have to wait longer and wait for the development and release of the new version of the 5G standard. Need to wait for the maturity of the industrial chain.

5G door opened, operators ushered in a new era, from the previous technology drive to the application drive, need to explore, need time to wait.

Q: when can I buy a 5G phone?

A: listed in the second half of 2019, it is recommended to buy in 2021

In practical applications, the speed of 5G is more than 10 times that of 4G network. A 1G movie is "seconds". You don't have to wait for buffer when watching videos online. When you play a large mobile game, you won't get stuck. The ultimate speed of 5G network is let. People yearn for. As a result, more and more users ask: When can I use a 5G mobile phone? Is the 5G mobile phone expensive?

At present, many mobile phone manufacturers have announced the launch of their 5G mobile phones. Huawei's 5G folding screen phone Mate X, Xiaomi Mix3, ZTE Axon 10 Pro 5G, oppo Reno 5G version, vivo NEX 5G version, Samsung S105G version and Samsung 5G folding screen phone Galaxy Fold, etc. Although some of the existing 5G phones will be available in the second half of this year, considering the progress of 5G network deployment, the large-scale shipment of 5G handsets will wait until 2020.

On the network, there are digital bloggers exploding the price of the 5G mobile phone of the Bank of China, the price of the OPPOReno 5G version is 11,800 yuan, the price of the ZTE AXON 10 Pro5G version is 10,800 yuan, and the price of the Huawei Mate 20 X 5G version is 12,800 yuan. Vivo NEX 5G version is priced at 11,800 yuan, millet MIX 3 5G version is priced at 11,800 yuan. Even if you can afford a mobile phone, ordinary users should consider the problem that they can't afford. Considering the price and traffic charges of 5G mobile phones, if you want to get 5G mobile phones with high price, you should wait until 2021.

Why not recommend users to start 5G mobile phones in the second half of 2019? To discard the price and tariff factors, users also need to consider the experience. First of all, 5G mobile phones must have supporting 5G base stations. At present, the construction of 5G base stations by domestic operators is still far from enough. In addition, the release of the first batch of 5G mobile phones is mostly due to the propaganda needs of mobile phone manufacturers. Even if users start 5G mobile phones, Most of the time, 5G networks cannot be used.

Secondly, there is no rigid application of 5G mobile phones at present, and the mainstream application in the user's mobile phone, 4G can meet the network speed needs. Finally, the industrial chain of 5G mobile phones is still immature, and the technology is greatly replaced. The first batch of 5G users are likely to become "experimental mice", which will encounter problems such as large heat generation and fast battery consumption.

Q: is the 5G fee expensive?

A: 5G tariffs will not be more expensive than 4G.

At first glance, the foreign 5G package fee is prohibitive, the total price of the package is higher than 4G, but from the flow unit price, 5G fee does not rise but drop. It is expected that China's 5G tariff will not be more expensive than 4G.

The United States and South Korea are the earliest commercial 5 gigabytes in the world, and have now launched 5G tariff packages. The US operator Verizon starts at 570 yuan a month, and the three South Korean operators start at 325 yuan a month. At first glance, the foreign 5G package fee is prohibitive, and the total price of the package is higher than 4G, but compared with the unit price of traffic. The 5G tariff is reduced instead of rising.

Us operators AT&T and Verizon have announced 5G package fees, the Verizon starting file is $85 a month, unlimited traffic, but speed mandatory control, can only watch 480p video, almost useless; The highest file is the real 5G network, $105 a month, unlimited traffic, the fastest network speed up to the 625MB/s.AT&T fee level is not significantly different from Verizon, the starting price is $70. Compared with 4G charges, the total price of the package is not much higher, more than 300 yuan can enjoy the 4G traffic of 40GB.

The discount on LGU+ is a 25 per cent discount on the monthly rental fee, calculated on the basis of a file of 75000 won in the main push package. The monthly discount is only 41000 won (about 2.44 yuan). You can enjoy 150GB traffic, equivalent to 2.2 yuan / GB.. For Korean users, this is simply the price of cabbage. Because as far as the 4G package of LGU is concerned, it is basically at the level of 34 yuan / GB. Moreover, the starting price of Korean tariff package is not low, the first two years are basically about two or three hundred yuan.

As for China's 5G tariff, it will not be more expensive than 4G. After several years of speed-up and fee reduction, China's 4G tariff is already at a global low level, with 5G charges expected to be at 1 yuan / GB, according to senior Chinese operator officials.


Q: Which 5G chip is strong?

A: Qualcomm, Huawei stands in the middle of the stage

Chip-the core technology of 5G mobile phone, and the chip responsible for communication is baseband, which also means that 5G mobile phone can not be separated from 5G baseband. With huge investment in chip research and development, even Apple was stuck in the neck because of a "lack of core." Apple's 5G phone was delayed. In April, Apple reached a settlement with Qualcomm, while Intel announced its withdrawal from the mobile 5G baseband market.

In addition to Intel, there are five companies that publish 5G chips worldwide, namely Qualcomm, Huawei, Samsung, Ziguang Zhanrui and MediaTek. Among them, Ziguang Zhanrui and MediaTek are weaker. Samsung's 5G mobile phone Galaxy S10, which has been sold in South Korea, uses its own chip ExynosModem 5100, but the results are unsatisfactory, not only in the coverage and speed, but also in 4G and 5G switching. It is not smooth.

Standing in the middle of the stage are Qualcomm and Huawei. As early as 2016, Qualcomm launched its first 5G network X50 modem, and then released the second generation X50 function in 2018. Qualcomm released Snapdragon X55 in 2019, in 5G mode. Snapdragon X55 can achieve up to 7Gbps download speed and up to 3Gbps upload speed.

At present, most of the 5G mobile phones announced by domestic manufacturers use Qualcomm's chipset. The mainstream mobile phone manufacturers such as Xiaomi, OPPO, LG, ZTE, and Lenovo all open 5G mobile phones equipped with X50 baseband at MWC. It is worth noting that the X50 baseband is introduced too early, not only behind the 28nm process, but also supports NSA, does not support SA, only supports NR-TDD, does not support NR-FDD. Although the Xiaolong X55 is a true 5G chip, the chip will not be put into commercial use until the end of 2019.

Huawei's Barong 5000 time is earlier than the Xiaolong X55. The Barong 5000 was the first single-chip multimode 5G chip at that time. It can support 2G, 3G, 4G and 5G, and is compatible with both NSA and SA dual architectures. The world's first commercial 5G chipset to support the 3GPP standard. At present, it is the Xiaolong X55 that can compete with the Barong 5000. However, from the application of these two chips on the mobile phone, Huawei is one step ahead and released the 5G mobile phone Mate X with the Barong 5000.

In the initial stage of 5G, manufacturers hope to occupy the high ground with mobile phones, and the competition between chips is becoming more and more fierce. In the mobile phone baseband chip market, whether Qualcomm can continue to stand firm and dominate, it will wait and see.


Q: After 5G matures, will there be 3G and 4G?

A: You need to coexist with 4G to better serve users.

There is no doubt that the answer is yes, whether in the early stages of 5G or after the maturity of 5G, 3G/4G networks, especially 4G networks, will still exist for a long time and continue to serve users.

From the historical experience, after each new communication technology appears, it has to be compatible with the previous generation network. Since 2014, 4G has been fully used in China, 3G network still exists, even the older 2G is still in service. There are many reasons. It will take a long time for users using the previous generation network to withdraw from the network, and at the same time, at the technical level, it also needs the previous generation network, such as voice, before VoLTE is truly reliable and fully popularized. Mobile voice service still needs 2G/3G to carry, but also can not be separated from it.

This is still the case in the 5G era, and it takes a long time to coexist with 4G to better serve users.

From the point of view of investment and network coverage, 5G and 2G/3G/4G are completely different states, the investment scale is much higher, operators can not completely 5G continuous coverage in a short period of time, let alone deep coverage. In this case, 4G network can not give up, but to do better.

From a technical point of view, 4G is still indispensable. At present, 5G has two routes: NSA (non-independent networking) and SA (independent networking), especially NSA, needs to rely on 4G core network. It can be seen how closely the relationship between NSA 5G and 4G is. Although NSA will eventually evolve to SA, it is difficult to determine how long it will take.

Even with SA 5G, the relationship with 4G is inseparable. Obviously, for a long time, the voice call of 5G network is still dependent on VoLTE in the 4G era, which is inseparable.

Therefore, operators have clearly stated that 5G and 4G will coexist for a long time. For example, China Telecom, in its "5G White Paper" white paper, clearly stated that "an important prerequisite for the evolution of 5G networks is that 4G and 5G networks will coexist for a long time." China Mobile also clearly stated that "5G and 4G will enter the 5G era." Long-term coexistence."

All in all, 5G and 4G will develop together. There is no you without me, but you have me.


Q: when 5G comes, will VR have a chance?

A: of course, it is a necessity for the future world

The greatest impetus for science in history is to break the inherent understanding of time and space. In a sense, your relationship with the surrounding space is the basis and origin of your relationship with society as a whole, and VR/AR, It is this sense of space that is broken. In any picture of the future imagination, human beings wearing VR/AR equipment are indispensable.

Undoubtedly, VR/AR will be one of the most important production tools for the fourth scientific and technological revolution. From the stand up to the heavy dust, VR/AR has only been used for just one year, and has been moving forward since then, screen resolution. , video stream, network speed... The virtual world is not so easy to integrate with the real.

Now, the VR/AR takes off again and the east wind is ready.

On March 1, the Ministry of Industry and Information Technology, the State Administration of Radio and Television, and the Central Radio and Television General Station jointly issued the Action Plan for the Development of Ultra High definition Video Industry (2019-2022), which clearly defined the industrial route of "4K taking into account 8K first," which is expected to be 2022. The 4K industrial ecosystem is basically perfect, and the research and development and industrialization of 8K key technology products have made a breakthrough. However, using 4K or 8K resolution screen, VR screen will no longer have the grid feeling that puzzles users.

AI technology, such as image recognition and deep learning, can improve the picture quality to 8K in less content through algorithm, or in the case of unsatisfactory network, by predicting that users are used to making good cache in advance and transmitting code stream in a more economical way. Reduce the occupation of bandwidth.

With the maturity of 5G and edge computing, end-to-end time will be shortened to less than 40 milliseconds or less, and VR's biggest roadblocker - the dizziness caused by "cognition-organ" will no longer plague users. With the introduction of VR cloud by telecom operators, the cloud becomes the most important bearer platform for content. VR devices have the potential to lose weight, and the power consumption and cost are reduced. Not only does VR helmets become possible, but the appearance of devices will also occur. It’s completely changeable and it’s possible to carry it with you. "5G is not a icing on the cake for VR, but a gift in the snow." Xiong Wen, the intelligent CEO of iQiyi, who just released the third-generation VR helmet at the iQiyi World Congress on May 9th, expressed the VR industry's desire for 5G.

The importance of VR/AR for the future is not that it is just a tool for entertainment and life. It is a necessity in the future world: medical, industrial, entertainment, social, gaming... Like 5G, VR/AR will become the foundation of society. facility.


Q: can 5G break down the information barriers in remote mountain areas?

A: it has nothing to do with 5G. What is missing there is not 5G, but the network.

Frankly speaking, whether it is possible to break the information barrier has nothing to do with 5G. The number of base stations in the 5G era will be more than twice that of 4G, and the distance between base stations is between 100 and 200 meters. For the "Wangshan Run Dead Horse" In the vast mountainous area, it is obviously impossible to achieve.

At present, there are still more than 30,000 administrative villages, islands and scenic spots in the country that have no signal or mobile broadband. It is difficult to obtain sites in these areas, or the construction of optical fiber networks is difficult. For 5G network which relies on optical fiber network to transmit base station signal, it is difficult to solve the coverage problem fundamentally.

Of course, there is nothing that can be done. The microwave base station is the most feasible solution. At present, Huawei's 5G+ microwave combination solution can complete the connection between 5G base stations by microwave, and form a seamless coverage of the mobile network through the “air relay” method. This method solves the problem of laying the base station optical cable.

However, the problem of microwave base station also originates from frequency. At present, the frequency used in mainstream microwave communication is between 3GHz-40Ghz. Like millimeter wave, there are many problems, such as high frequency, length of wave, poor penetration, large attenuation, short transmission distance and so on. Its transmission distance must be within the visual range. Therefore, if rural and mountainous areas are to be covered, the number of base stations and the cost of building stations will rise significantly, which may not be a valuable way from a commercial point of view.

Judging from the current construction plans issued by the three major operators, they are basically giving priority to the development of 5G in first-tier cities. Mountain areas want to use 5G, and it is estimated that it will take a few years to wait.

While people in first-tier cities are wondering whether 5G can reduce the speed of movie downloads from 10 minutes to 1 minute, many elderly and children in mountainous and rural areas in China just want the phone to stop off and on. For them, what is missing is not 5 G, but the network.

Perhaps another microwave base station is worth looking forward to - satellite. The higher the satellite base station is from the ground, the wider the coverage. Therefore, many private satellite companies in China are working on the near-orbit satellites with a distance of 1,000 kilometers. It is hoped that the "constellation" composed of artificial satellites will cover the whole world and become the air. Basic communication operator". Obviously, the satellite approach is more suitable for solving the Internet problem in remote mountainous areas, but its shortcomings are low bandwidth, unstable signals, and the risk of continuous investment by private enterprises.

In fact, the fundamental reason to solve the problem of Internet access in mountain areas lies in the cost. The network coverage problem in poor mountain areas should be a special "poverty alleviation plan", so that the "information superhighway", like roads, can become the only way for villagers to become rich.


Q: what is the relationship between 5G and AI?

A: the index of AI productivity is 5G

In order to purchase the bank for loan, the previous loan approval takes a month, now it may only take a day or two to go through the process, because the terminal machine scan the data, the machine can show the couple's assets, consumption capacity, loan repayment ability. In the field of financial credit, the efficiency of AI has increased by more than N times.

Tuberculosis patients walked into the hospital to film, facing a large number of tuberculosis patients, doctors read a large amount, difficult, and may have a wrong judgment. With the help of AI, the previous chest radiography takes 3 minutes, and now it can be judged in 2 seconds.

The rapid development of artificial intelligence has brought huge imagination space in all kinds of industries. However, at present, AI is still facing difficulties and become shackles, such as relying too much on the cloud, because Wi-Fi, broadband and other data transmission bandwidth is limited, resulting in delay affecting decision-making; The situation information in the training sample is limited, and the information source in the actual environment is insufficient, which makes some judgments out of practice and so on.

The three characteristics of 5G are high rate, low delay (0.5ms), wide connection, and the requirement of 5G core network distributed architecture to extend to the edge, which solves the bottleneck of the interconnection of everything-the computing power of edge computing has been liberated. The core elements of artificial intelligence are data, computing power, algorithm, 5G, while providing support for computing power, it also solves the data problem. 90% of AI data sources come from the Internet of things, because 5G can connect to more devices. The rapid development of the Internet of things will produce a lot of data, the potential of AI will be further released, more data will make AI more accurate and intelligent. Ai technology will also be applied to the 5G core network to help the core network in the deployment planning. Operation and maintenance and other aspects to achieve a high degree of automation and intelligence.

5G is the foundation of high speed network, AI is a general technology, which can empower all kinds of industries. The relationship between 5G and AI is not simply superimposed and promoted, but mutual index, in intelligent city, intelligent manufacturing, intelligent driving. Intelligent health care and other fields liberate each other's productive forces. Although the industrial chain is still in the exploratory stage, the deep combination of 5G and AI will become an infrastructure capability over the next five years, 10 years or more. Like the Internet, once again innovate the daily production and life of human beings.

Q: Can 5G stocks be bought?

A: There are more good news, but still need to be cautious.

Since the beginning of this year, the concept stocks such as 5G and edge computing have continued to strengthen, and the public's enthusiasm for 5G has been rising. According to previous Wind terminal data, the 5G index has risen more than 44% since 2019.

From a policy perspective, since the first 5G standard (R15) was launched in June 2018, the information leaked from the policy is constantly advancing 5G. In December 2018, the Central Economic Work Conference proposed to accelerate the pace of 5G commercialization; during the 2019 National Conference, 5G was first written into the government work report, and the initial investment in the industrial chain was clearly affirmed. At the same time, Miao Wei, Minister of the Ministry of Industry and Information Technology, said that unlike the previous commercial use nationwide, the state will issue 5G temporary licenses in several urban lines in 2019, enabling large-scale networking to take the lead in some cities and hotspots. At the Boao Forum for Asia, Miao Wei once again revealed that the 5G license will be issued in a timely manner according to the maturity of the terminal. It is estimated that it is possible to issue a 5G license at some point this year. Some insiders believe that the important probability of this important time node will be 5.17 World Telecommunication Day. By then, 5G will regain strength.

Although the policy is improving all the way, 5G commercial enterprises need to jointly promote equipment manufacturers, operators and mobile terminal manufacturers. Buying stocks still requires rational thinking. While calling for the arrival of 5G commercials, investors need to think about which companies will have more room for development in the next decade, whether the company has a good management team, whether the current stock price of each company is reasonable, etc., and then decide not to follow suit blindly.


Q: what is 6G?

A: Not only download speed, but also human service

The evolution routes from 2G, 3G, 4G to 5G and 6G do not conquer the peaks of 2000 meters, 3000 meters or 4,000 meters in succession. There are many factors that determine the technical characteristics of 6G, such as the degree of global wireless technology development, the world economic situation, and the global environment. Change, space technology maturity, etc. It is no exaggeration to say that a global economic crisis may change the technical form of 6G.

The lonely whale uses the 52Hz (Hz) frequency to exchange the companions. The newborn baby reminds her mother of the existence with the scream of 1000Hz frequency. The roaring train stops the attention of everyone with the roar of 3000Hz frequency... ...the story of all wireless communications, in the final analysis, is the story of frequency.

6G is no exception. In the 5G era, the frequency bands that people can use are still mainly concentrated below 100 GHz. When people are more eager to pursue the speed and capability of wireless communication, scientists and engineers will always look to the higher and not be used by humans on a large scale. The frequency of development, because here is the virgin land of wireless communication. Scientists in China, the United States, Japan and other countries have begun to study wireless communication above 1000 GHz. The industry calls it terahertz, and the theoretical download speed can reach 1 TB per second.

However, it is undoubtedly narrow to use download speed to evaluate 6G. At present, scientists' ideas for 6G also include satellite-based high-altitude wireless platform, nano-scale antennas all over every corner, decellular structure, used in energy-level production, movable and even flying sensors, and so on. For some time to come, scientists at home and abroad will argue about these concepts until a consensus is reached.

Once again, all the discussion about 6G is just prediction, and no one can predict the wheel of history. The technical characteristics of 6G in the future will start with the needs of human development, if the most intractable problem for mankind in a few years is the economic recession. Then 6G will move towards the goal of commercialization; If humans face a shortage of labor, then 6G will have more technical characteristics to replace human labor.

Science and technology are people-oriented, and 6G is also for human development. Don't look forward to looking forward to 6G, one day 5G SA independent networking has achieved wide area coverage, a variety of 5G network slicing, rich and colorful industry applications, people often hundreds of megabytes per second download speed is not surprising. By that time, he might have stood at the gate of 6 gigabytes.
