Free Single Chapter (3)

  eMBB, literally translated as "enhanced mobile broadband", is a human-centered application scenario, which is concentrated in the ultra-high transmission data rate and mobility guarantee under wide coverage.

  In the future, personal understanding, making calls, sending text messages, listening to music, watching sports, plus background data and processing related to base stations and switches.

   In the era of 3G and 4G, this is what communication standards are all about!

   But in the 5G era, we have two more application scenarios. I will give a brief introduction later.

   Now talk about embb.

   Let me talk about that vote, it was actually two votes. What is certain is that Fantasy stood with American and Japanese manufacturers the first time, and voted for Huawei for the second time.

   But if fantasy is the culprit, then it is really high, just because the name of fantasy seems abrupt among many American and Japanese manufacturers.

   In the two votes, the fantasies and the Motorola votes it represents are of little importance. In other words, it is no different without it. An enterprise without core technology is not a **** in 3GPP! (personal resentment)

   Now back to the topic:

  In the embb scenario, there are two channels, the user identification code (long code) and the base station identification code (short code).

  Two encoding technologies, one is Qualcomm's LDPC, we call it Infantry, and the other is Polar, we call it Cavalry.

   Infantry is fifty years old technology, mature and stable.

  The cavalry is a student of the inventor of the infantry, a polar code technology invented by the Turks.

You must know that some speed requirements of 5G are more than ten times that of 4G. In a certain test, although the cavalry is a student, its speed is closer to the polarization value, reaching 27G, while the infantry, although it has no horses, is slow A bit, but it also reached the requirements of 5G, reaching 21G.

   So, they all fit the bill.

   Having said that, here comes the point:

   in this battle of standards.

  To win, patents are useful, and to lose, those patents that are painstakingly researched.

   So things got here and everything was clear.

  Huawei, ZTE, and countless domestic communication manufacturers are working hard for China to compete for international communication standards.

  Why use your code? Europe also has it, Japan also has it, why not use theirs?

  Because, this is a national power struggle!

   It doesn't matter what flowers are used for mobile phones, what domestic operating systems, what semiconductors, what patriotism!

  Those are just the means by which the United States suppresses us.

  Before, they used soybeans to suppress us, they used oil to suppress us, and they used futures to suppress us. Now, it has been replaced by high-tech!

   So where did the national strength come from?

Most of the time, we swallowed our breath, took cheap labor, and exchanged some pitiful hard-earned money. We frantically destroyed our natural resources, just for the evil foreign exchange. Think about it, I haven’t said that for a long time, China The land is vast!

   Since joining the WTO, our country has lost its face, and the world is playing hooligans everywhere!

   For more than ten years, we have fought countless state-owned enterprises in the soybean, oil, and futures wars, losing first and then winning, but never hyping it up.

   More than ten years ago, the words of the Director of the Department of Foreign Affairs are still vivid in my mind:

   "It's just a fool, a fool!"

but

   In the past, we protested, but now we don’t protest, and we expel them directly.

   In the past, when we voted at the United Nations, we were unhappy and abstained. Now, we are unhappy and directly veto.

  In the past, the United States sanctioned us, and we smashed our broken teeth into our stomachs. Now, we directly counter the sanctions.

   This is a situation that more than one billion people across the country have worked together to achieve.

   Buying Huawei is patriotic!

   I agree with this sentence, but the score is clear.

  Otherwise, the United States will increase taxes by hundreds of billions, and the hard-working ordinary people who have suffered countless victims will not agree.

  The development of China to this day has been achieved by the efforts of 1.4 billion people. How can it be credited to the family when it comes to the mouth of some We-media public accounts?

  Sorry for digressing.

  Speaking back to 5G, the final result of the national competition is that the long yards use Qualcomm's infantry, and the short yards use Huawei's cavalry.

   This is the result of compromise by all parties. The fantasy factor is insignificant. This incident itself is just the fuse of the long-term accumulation of certain factors. Whether it is related or not, we just want to find an excuse to slap you! You don't even have to tell the difference, because no one will listen!

   In this round, Qualcomm won, and Hua Wei did not lose!

   In addition, 5G is popularizing vigorously, but its standards have not yet been formulated.

   The following are the most critical, two extra scenarios from 5G:

The first one: uRLLC, which corresponds to the Internet of Vehicles, industrial control, and telemedicine. To give two simple examples, when the autonomous driving technology overtakes, it is impossible to see whether there is a car before the car, but 5G can see it, so It avoids the possibility of accidents. Of course, controlling the excavator in the home computer is also an example.

   The second one: mMTC, literally translated as "mass Internet of things". In our country, it is also called the Internet of Everything! The powerful connectivity capabilities of 5G can quickly promote the deep integration of various vertical industries (smart cities, smart homes, environmental monitoring, etc.).

   In the article, Zhao Song spent millions of applications on the Crestron smart home system, and in the 5G era, he may be able to complete the network construction himself.

   These two standards, according to my understanding, will be formulated in 2020.

   Therefore, the road of Chinese manufacturers has a long way to go!

   The above are some simple views of 5G. Of course, there are countless concepts, which can’t be described in many pages.

  Science and technology know no borders. 3GPP designates the purpose of high standards of madness, regardless of family and country factors, and ultimately is for the rapid development of mankind.

   However, in addition to 5G, to achieve the goals of 3GPP, of course, the most critical one is computing.

Some people say that quantum computer is a good opportunity for us to overtake in a corner. However, I personally have no idea about it. In this regard, IBM in the United States has already produced a prototype internationally. I don’t know how it performs. ~

   Therefore, aside from the illusion of quantum computers and photonic computers, we still return to cloud computing in a down-to-earth way, and computing requires data, so big data came into being.

   In this article, these two concepts have not been studied in depth. Many book lovers who have read it in the fog can check it out according to my instructions.

  One kilometer corresponds to Amazon plus convenience stores, massive commodities, countless suppliers, huge customer groups, and the scale of data generated.

   Therefore, Shenzhou Technology wants to produce commercial terminals, one of which is a 7*24-hour commercial machine, and the other is a server.

You probably all know what    three links and one reach are, so I won’t explain more.

   Next, let’s talk about the reason for writing popular science today: standards.

   Zhao Song wants to get SDRAM, in fact, he wants to participate in the memory standard organization.

  The familiar three letters of DDR are not so much a technology as a standard.

  Because, it is indeed an interface standard, an interface standard that is only developing and has not changed

  Iron memory means that its technological development is a semiconductor technology that is least restricted by the lithography process (one-sided understanding).

   Therefore, Zhao Song needs some kind of advanced integrated technology in the world. In 2001, the unprecedented cold current of the semiconductor industry was the best opportunity.

   In addition, the cycle of the chip is very long. This article is shortened because of Zhao Song's golden finger. Please don't worry too much about it.

   This is a half-spoiler, I guess many book friends can be written and run away.

  Conclusion:

   At present, the first biological agent developed with machine intelligence has entered the testing stage. In the future, with the help of 5G, we can imagine that countless terminal diseases will eventually be conquered by machine intelligence.

  Some people say that the ultimate development of mankind has only two results, either self-destruction or world harmony.

  Who knows, I just want to come back to reality, do my own thing, don’t ask for much contribution, and don’t get into trouble!

above.

   PS: In terms of patents, no matter which code is involved, various international companies are involved, but the main direction is different.

   In addition to the national competition, please pay attention to a quail company - Samsung.

   In some patents, it is the world's first, no matter which standard is used, it is not afraid!

   I wrote 8000 words today.

   My child starts school tomorrow, I will accompany me in the evening. I can't guarantee that the text will be corrected later.
