eMBB, literally translated as "enhanced mobile broadband", is a human-centered application scenario, which is concentrated in ultra-high transmission data rates, guaranteed mobility under wide coverage, etc.
In the future, my personal understanding will include making phone calls, sending text messages, listening to music, and watching competitive sports, plus background data and base station and switch-related processing.
In the 3G and 4G era, 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 in the following article.
Now let’s talk about embb.
Talking about that vote, it was actually two votes. What is certain is that the first time, Fantasy stood with American and Japanese manufacturers, and the second time, it voted for Huawei.
But if Fantasy is the culprit, that's a big deal. It's just because among all the American and Japanese manufacturers, Fantasy's name seems awkward.
In the two votes, Fantasy and the votes it represents for Motorola are insignificant. In other words, it is no different with or without it. An enterprise with no core technology is nothing in 3GPP! (Personal resentment)
Now back to the topic:
In the embb scenario, there are two channels, user identification code (long code) and base station identification code (short code).
There are two coding technologies, one is Qualcomm's LDPC, which we call infantry, and the other is Huawei's Polar, which we call cavalry.
Infantry is a technology from fifty years ago, 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 horse, is slower.
It's a bit off, but it also meets the requirements of 5G, reaching 21G.
So, they all meet the requirements.
Speaking of which, here comes the key point:
In this battle for standards.
If Huawei wins, then it and the related technology patents developed by countless Chinese manufacturers around the cavalry will become tools for controlling the right to speak in the future, and only then can they become the real benefits in the end.
If he loses, what if he has the largest number of patent applications in the world? Those patents... the consequences are self-evident.
So now that things are here, everything is clear.
Huawei, ZTE, and countless domestic communications manufacturers are working hard to help China compete for international communications standards.
Why should I use your encoding? There is one in Europe and one in Japan, so why not use theirs?
Because this is a battle of national power!
.....................
It has nothing to do with what kind of mobile phone, what kind of domestic operating system, what kind of semiconductor, what kind of patriotism!
Those are just the means used by the United States to suppress us.
In the past, they used soybeans to suppress us, oil to suppress us, and futures to suppress us. Now, they have switched to high technology!
So where does national power come from?
From the fact that most of the time we swallow our anger and use cheap labor in exchange for pitiful hard-earned money, we crazily destroy our own natural resources, just for that evil foreign exchange, think about it, how long has it been since I said, China
The land is vast and abundant!
Since joining the WTO, our country has lost face and acted like a hooligan everywhere in the world!
Over the past decade or so, we have fought countless state-owned enterprises in soybean, oil, and futures wars, losing first and then winning, but we have never publicized them.
More than ten years ago, the words of the Director of the Foreign Affairs Department are still vivid in my mind:
"It's just coward, totally coward!"
but........
In the past, we protested, but now we no longer protest, we are directly expelled.
In the past, when we voted in the United Nations, if we were unhappy, we would simply abstain from voting. Now, if we are unhappy, we would directly veto.
In the past, we smashed our teeth and swallowed the U.S. sanctions. Now, we directly oppose the sanctions.
This is a situation achieved through the joint efforts of more than one billion people across the country.
Buying Huawei is patriotic!
I agree with this sentence, but one has to decide priorities.
Otherwise, if the United States raises taxes by hundreds of billions, the conscientious people who have suffered countless losses will not agree.
China's development to this day has been achieved through the efforts of 1.4 billion people. How come some self-media public accounts only take the credit for one family?
............................
Sorry, I got off topic.
Talking back to 5G, the final result of the national strength competition is that long codes use Qualcomm’s infantry, and short codes use Huawei’s cavalry.
This is the result of a compromise between all parties. The fantasy factor is insignificant. The matter itself is just the trigger of the long-term accumulation of certain factors. Regardless of whether it is related or not, we just want to find an excuse to attack you! You can’t even tell the difference.
No need, because no one will listen!
........
In this round, Qualcomm won and Huawei did not lose!
In addition, 5G has been popularized with great fanfare, but its standards have not yet been formulated.
The following are the most critical, two additional scenarios of 5G:
The first one: uRLLC, which corresponds to the Internet of Vehicles, industrial control, and telemedicine. To give two simple examples, when overtaking with autonomous driving technology, you cannot see whether there is a car in front of the car in front, but 5G can see it, so
This avoids the possibility of accidents. Of course, using a computer to control an excavator at home is also an example.
The second one: mMTC, literally translated as "massive Internet of Things". In our country, it is also called the Internet of Everything! The powerful connection 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 to apply the Crestron smart home system. In the 5G era, he may be able to complete the network construction by himself.
According to my understanding, these two standards will be completed in 2020.
Therefore, the road ahead for Chinese manufacturers is a long one!
.............
The above are some simple views on 5G. Of course, there are countless concepts that cannot be explained in any amount of space.
Technology has no borders, and 3GPP has set crazy high standards for the purpose of setting aside family and country factors. After all, it 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 needed, and that is computing.
Some people say that quantum computers are a good opportunity for us to overtake in corners. However, I personally have no idea about this. In this regard, IBM in the United States has already produced a prototype internationally. I don’t know how it performs. It looks really beautiful.

Therefore, putting aside the fantasy of quantum computers and photon computers, we should return to cloud computing in a down-to-earth manner, and computing requires data, so big data emerged as the times require.
In this article, these two concepts have not been studied in depth. Many book friends who are confused can check it according to my instructions.
One kilometer corresponds to the scale of data generated by Amazon plus convenience stores, massive products, countless suppliers, and a huge customer base...
Therefore, Shenzhou Technology wants to produce commercial terminals. One of these devices is a 24/7 commercial terminal, and the other is a server.
You probably all know what three connections and one extension are, so I won’t explain it further.
Next, let’s talk about the reason for writing popular science today: standards.
Zhao Song wanted to get SDRAM. In fact, he wanted to participate in the memory standards organization.
The three letters DDR that everyone is familiar with are more of a standard than a technology.
Because it is indeed an interface standard, an interface standard that is only developing and has not changed so far.
The iron-clad memory means that its technological development is a semiconductor technology that is least restricted by the photolithography process (one-sided understanding).
Therefore, Zhao Song needed some kind of technology from the world's advanced integrated circuits. In 2001, during the unprecedented cold wave in the semiconductor industry, that 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 considered a semi-spoiler. If it is still unclear, I think many book lovers will be written off.
.............................
Conclusion:
Currently, the first biological drug developed using 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 return to reality, work hard to do my own thing, don’t ask for much contribution, and don’t get into trouble!
