"Mr. Chen, are you kidding me? Gaotong Company really signed a 4G network technology sharing contract agreement with us?"
Deutschman's eyes flashed with surprise.
He is eighty-nine years old this year. Age represents experience to a certain extent, so he also thinks that he is well-informed. There are not many things in this world that can surprise him.
But this time.
He was still shocked.
How much leverage did Chen Xing have to get Gaotong Company to sign a technology sharing contract for the 4G network?
Although age can represent experience, it also has a disadvantage, that is, it is difficult to accept new things. In addition, being in a foreign country, he has no idea about the infringement of Gaotong Company.
"Professor Deutschman, you don't know something. Some time ago, we found that Gaotong Company infringed the "DSP Multi-Core Architecture Technology". This is just compensation obtained through legitimate rights protection negotiations." Chen Xing explained At the same time, he looked at Qian Yu, Shen Sen and Yu Bicheng, as if wondering why they didn't tell Deutschmann.
Isolation?
Probably not!
"During this period, Professor Deutschman has been optimizing the algorithm of the 5G network day and night. We are also working on the overall architecture of the 6G network, and we don't have much time to interact with it."
Qian Yu explained.
His words were rather reserved.
Although they all work on the same floor, there are dozens of independent laboratories in this space.
To put it bluntly.
It is a niche laboratory.
This is like classmates in college. Even if they are in the same class, it is impossible to say that everyone knows each other, because after going to college, everyone is busy with their own things.
"That's true." Shen Sen responded and continued: "Recently, the tasks at hand are quite heavy and I don't have time to share information. I will pay attention to this issue in the future."
"The main reason is that everyone is very busy, and it is normal to have less communication. By the way, Mr. Chen, that means we can now use Qualcomm's 4G network technology?" Deutschman came out to smooth things over, not wanting to let the atmosphere in the laboratory become cold.
“Well, all available.”
Chen Xing nodded in response.
The fact that Deutschmann didn’t know about Qualcomm’s infringement was not something he was making a fuss about. The main reason was that Deutschmann was almost ninety. It was obviously unrealistic for him to go to the Internet to get the information by himself. Have someone to share the information with.
After all, they traveled thousands of miles to Shenzhen to help Longxing Group develop a 5G high-speed network. However, apart from scientific research, they knew nothing about it. This was a bit too chilling.
However, they did not dwell on this topic. After Chen Xing reminded him, he also changed the topic and said:
"Our contract has clearly written, "Spread Spectrum Communication Technology, a Branch of CDMA Digital Technology", "OFDMA Multiple Access Technology", "MIMO Multiple Input Multiple Output", "OFDM Orthogonal Frequency Division Multiplexing" and other technologies related to 4G communication networks, Gaotong Company must unconditionally, royalty-free, and permanently authorize Fang, which is used by our Longxing Group.”
“This is great!”
Daoyichman’s eyes flashed with excitement.
The main reason why they are unable to develop a true 5G high-speed network is that they cannot bypass Gaotong's patents.
Everyone who has engaged in scientific research knows that technology has the characteristics of extended development.
For example, some technologies of the 4G network can be applied to the 5G network.
If you choose to bypass it and choose other methods instead, it is likely to greatly reduce the speed of the Internet.
Why did Deutschmann initially say that Longxing Group was not developing a 5G network, but 4.5G, 4.6G or 4.7G?
The problem is that some network technologies cannot be circumvented, or if they are circumvented, the 5G network speed will be greatly reduced and cannot meet the ideal requirements.
For another example, why have high-end automobile engines, such as eight-cylinder or sixteen-cylinder engines, been unable to be domestically produced?
Four words, patented technology!
The patented technology certificate of the internal combustion engine can be stacked hundreds of meters long. When you are halfway through research and development, you will definitely infringe other companies. If they don’t agree with your use of technology, they can only bypass it. The performance will be greatly reduced. If it cannot be circumvented, there will be no way to manufacture it, let alone make money on the market.
Gaotong's network technology may not have significantly improved the 4G network, but it is an indispensable puzzle piece for the 5G network.
“There is no need to bypass key technologies, then the real 5G network can be launched smoothly.” Yu Bicheng said with excitement in his tone.
“Then we can temporarily put aside the 6G network and improve the 5G network first.”
Qian Yu suggested.
"I have this plan." Shen Sen clenched his fists and planned to fight.
Originally, according to their predictions, the maximum speed of the "pseudo 5G network" independently developed by Longxing Group was 70MB/s. Now, everything is uncertain.
“You don’t need to put down the work at hand, just leave it to me and my team.” Deutschman volunteered.
Hearing this, Qian Yu asked in a concerned tone: "Is it really possible? Will the workload of the project be too large?"
"Yes, the 6G network cannot be rushed. If the workload of the project is too large, It’s too big, we can work together to optimize the 5G network first.”
Shen Sen agreed.
The 6G network needs to redesign the system network structure. According to their vision, they want to have a "three-layer, four-sided" network structure.
What is a three-layer, four-sided network structure?
The three layers refer to the cloud network resource layer, network function layer and application enablement layer.
The cloud network resource layer is responsible for carrying the infrastructure and resources of the 6G network. Resource types include various computing, storage, networks, spectrum and various dedicated facilities.
The network functional layer is the logical functional layer at the core of the 6G network and the main body that implements the core functions of the 6G network.
Based on the enhanced control plane and user plane of 5G network, it will also introduce data plane and intelligent plane to meet the richer functional requirements of 6G.
The last layer is the application enablement layer, which aggregates network service capabilities and common application service components, and provides services for applications or surrounding ecosystems through capability exposure, application enablement frameworks, etc., to achieve unified application usage. Can manage.
As for the four sides, they are the control side, the user side, the data side and the intelligence side.
You can imagine how much manpower, material resources and time it takes to develop 6G networks, and they are not in a hurry.
"I appreciate your kindness. In fact, I have already designed a 5G network model for internal testing." Deutschmann suddenly showed off.
Chen Xing: "???"
"What?"
Yu Bicheng and others were confused.
Don't say that Chen Xing is stunned now, they don't know that Doichiman has this skill and actually has a closed beta version!
"In order to compare and more intuitively see the limits of 5G networks, I made two models, one without circumventing technical barriers, and one that we have applied now."
Deutschman explained When, Chen Xing suddenly had a flash of inspiration and asked: "In other words, the 70MB/s you mentioned at the beginning was calculated based on another large 5G model?"
"That's right."
Deutschmann nodded and continued: "Because Gaotong Company has mastered too many mature information and communication technologies, and if you can use their technology, it is definitely best to use their technology, so I made it. Comparison model. ”
“According to my original test, under the same optimization conditions, the network speed of the 5G network model designed using Gaotong’s 4G extension technology can be increased by 30%, reaching 91MB/s”< br>
“That’s it.”
Chen Xing suddenly realized, looked at Deutschmann and said: “No wonder you often mention Gaotong’s 4G network technology to me. It turns out that it has been discussed in private for a long time. Tested.”
Since applying for a patent requires disclosure of the principle, it is not difficult to reproduce it privately.
Patent rights, as long as they are not publicly used for commercial purposes, no one will know if you use them privately.
This is why only business talks about patents, but there is no such thing as patents in the military industry.
"That's right, we only need an optimization update now to replace immature technology and make the 5G network more stable and faster." Deutschman nodded in reply.
Qian Yu, Yu Bicheng and others were not surprised. It is no secret that the laboratory uses registered patented technology privately, as long as it is not open for commercial use.
"Thank you for your hard work on optimizing the 5G network, Professor Deutschmann."
"No problem."
Deutschmann answered directly .
Because he is not talented enough, he cannot participate in the research and development of 6G network at all, and can only take root in 4G network and 5G network.
"That's right."
What did Chen Xing think of? He looked at Qian Yu and Yu Bicheng and said, "I heard you talk about the 6G network. What are the advantages of this generation of information and communication technology?"< br>
“The coverage of the 6G network is too wide.” Shen Sen took a step forward and continued to explain: “If I want to put it simply, it has higher speed, lower delay, Greater connection density, the most important thing is that it can fit your artificial intelligence"
"Big data?"
Chen Xing was stunned.
“That’s right!”
Shen Sen nodded and responded: “It’s big data. Moreover, we have also discovered two new spectrum communication technologies, namely "terahertz" "Communication" and "Visible Light Communication" are of great research value. "
"Terahertz, visible light spectrum communication..." Chen Xing was confused. This was a new technology that he had never heard of.
Seemingly seeing Chen Xing’s confusion, Qian Yu explained: “Terahertz may be unfamiliar to you, CEO, but if you name it in the optical field, far-infrared light, you will definitely not. It will be strange.”
“Far infrared light?”
Chen Xing was stunned again.
Of course he knows far-infrared light, which is widely used in products in the optical field.
There are also criminals who use it in health care products and devices, claiming that it can cure all diseases and deceiving a large number of consumers.
“Well, it has many names. In the optical field, it is called far-infrared light, in the electronic field, it is called submillimeter wave, and in our information and communication field, it is called terahertz.”
< br>
Qian Yu took a breath and continued: "Terahertz refers to electromagnetic waves with a frequency in the range of 0.1-10THz. It is between millimeter waves and infrared light. It is neither fully applicable to optical theory nor fully applicable to microwave theory. . ”
“According to our preliminary technical predictions, once terahertz communication technology is implemented, the maximum wireless transmission speed can reach 9GB/s”
Chen. Xing was stunned again.
He originally thought that the 6G network should still be measured in MB, but he did not expect that GB would be used to express the network speed.
What is the concept of 9GB/s?
A two-hour island country movie with high-definition and lossless quality only weighs ten or twenty gigabytes. Even if the file size is 30 gigabytes, at the speed of the 6G network, wouldn’t it be downloaded in the blink of an eye?
“Yes, it’s 9GB/s!” Yu Bicheng also responded, and then continued: “As long as terahertz communication technology is initially realized, we will become an unshakable giant in the field of information and communication. It's crushing the whole world!"
"This... This is not only crushing the whole world, it feels like real-time communication between stars is possible," Chen Xing thought to himself.
The advent of 6G network technology is not a small technological shock, but a revolutionary shock like nuclear fusion and room temperature superconductivity!
"What's the current progress?"
Chen Xing asked, holding back his excitement.
“It is still in its early stages. The 6G network is not only a project of our information and communication laboratory, but also requires the participation of other laboratories.” While responding, Yu Bicheng did not forget to mention other laboratories.
"Oh?"
"Need another laboratory?" Chen Xing continued to listen attentively.
“Yes, assistance from other laboratories is needed.” Yu Bicheng confirmed again and patiently explained:
“Because terahertz communication is a brand-new information and communication technology. , therefore, more efficient signal transceiver technology is needed, including frequency conversion circuits, mixers, frequency multipliers and amplifiers, etc. "
"At present, the output power and operating frequency of our equipment devices cannot meet the requirements of low power consumption and low power consumption. High efficiency and long life are required for commercial use.”
“It doesn’t need to be used for commercial use, as long as it can be used for personal use,” Chen Xing said quickly.
Is 6G network commercially available?
This is an egg for commercial use!
With the highest network speed of 9GB/s, even if Chen Xing dares to use it commercially, will users dare to use it?
Don't forget to turn off the Internet before going to bed, as the joke makes you, and you will owe the phone bill for an apartment in the Imperial Capital when you wake up.
The 6G network is not suitable for commercial use, but is suitable for internal research and development.
"If it is not for commercial use, the standards can be lowered, but we still need to wait for a specific reply from Chief Gao of the chip laboratory."
Qian Yu suddenly mentioned Gao Zhengqian.
"Chief Gao?"
Chen Xing looked confused.
Qian Yu: “RF devices that can meet the needs of terahertz communications require new semiconductor materials. We talked with Chief Gao, and he said that silicon germanium and indium phosphide may be able to manufacture new RF devices, allowing We patiently await his reply.”
"So that's it."
Chen Xing suddenly realized.
No wonder the West has racked its brains and tried its best to restrict semiconductors. It turns out that this field is so widely related.
CMOS sensors in the optical field and radio frequency devices in the information and communication field both require technical support from the semiconductor field.
"Then what is this visible light communication?"
Chen Xing asked again.
I originally wanted to come over to report the good news to the Information and Communications Laboratory, but unexpectedly these top engineers gave him a big surprise.
“Visible light communication, which is a more advanced communication technology than terahertz, can make it possible to have a network wherever there is light.”
Yu Bi’s idiom is amazing.
Deutschmann was also shocked.
Is the new generation of communication technology so abnormal?
Terahertz can reach GB-level transmission speeds, and optical communication can achieve optical coverage. Is this definitely a technology in the communications field?
“How to do it?”
Chen Xing showed interest.
(I want to climb up step by step)
(Waiting for the sun to look at its face quietly)
(Small sky has big dreams)
The ringing of the mobile phone interrupted the communication in the laboratory.
Chen Xing took out his cell phone to check and found that the call was from the security booth.
“Is someone coming to visit again?”
While muttering in his heart, he pressed answer and asked: "What's the matter?"
"Sorry, President, I may have disturbed you. It's like this. Now there is a meeting at the gate of the base who claims to be the FSA Financial Department of the island country. Commander, the gentleman named Saitoi said he wanted to talk to you about something, and he also showed the relevant documents. "
"Island FSA Financial Department?"
Six thoughts flashed through Chen Xing's mind. One word, the Securities Regulatory Commission of the island country.
Each country has a different name for the Securities Regulatory Commission, which is caused by cultural differences, but the scope of power and jurisdiction is similar.
“Yes.”
Security confirmed again.
"If people from the FSA Financial Department of the island country come to visit, it must be a matter of Nikkei 225." Chen Xing thought to himself and responded directly: "Send them away."
“Huh?”
The security guard was confused.
After staying here for so long, this was the first time he saw Chen Xing chasing someone away directly. The two of them had never even met.
However, Chen Xing also has his own reasons, that is, the president of the FSA Financial Services Agency of the island country came to the door just because he wanted Longxing Group to let Nikkei 225 go and stop short selling and engage in commercial competition.
But is this realistic?
Obviously, unrealistic.
In the past, when Japanese companies held a dominant position, they could restrict the export of photoresist and semiconductor equipment, and raise prices from time to time. Now that the offense and defense are easy to change, and the polarity is reversed, can you easily let them go?
Short Nikkei 225, Chen Xing can get what he wants, and if everything goes well, he can also control the company he wants.
Peace talks?
Go and dream!
"Just say I'm out and send him away." Chen Xing gave a random reason.
“Oh, I got it.”
After hanging up the phone, the security guard looked at Saitoi, who looked like a dog in front of him, wearing a suit and tie, and said: "Our president is still working outside, you should go back first."
As soon as he finished speaking, Saitoi said The translator on the side immediately translated it into Japanese.
After hearing this, Saitoi's face instantly darkened, he returned to the car with a slumped face, then looked at the driver and said: "Go back to the hotel."
"Go back? He was obviously there. "
The driver asked.
When the Gaotong Company negotiation team entered, they were actually already there and were observing from a distance.
Gaotong Company stayed inside for so long, and Ren Guofei also drove away, which shows that they are definitely done talking. In other words, Chen Xing is definitely at Longxing Base.
Taking a step back, even if Chen Xing is not at the Longxing base, security should not have this attitude. After all, there should be a vice president coming out to greet you. They are people from the FSA Financial Department of the island country. They can The only one who asked the security to expel them was Chen Xing.
"Chen Xing doesn't want to talk to us. Now we can only contact the relevant departments of Halong Country to ask what's going on."
Sai Toui's tone was threatening.
You must know that island country capital invests very heavily in Longguo, for example, car companies, many of which are joint ventures with Japanese companies.
For example, Internet companies such as Penguin and Alibaba have island capital shareholders, and they are major shareholders.
Saitoi's idea now is very simple. Since Chen Xing doesn't want to see him, he will find an intermediary to introduce him, and finally turn the hostility into friendship.
“So that’s it.”
The driver suddenly realized it and then reversed and left the Longxing Group headquarters base.
……
Information and Communication Laboratory.
After Chen Xing hung up the phone, he looked at Yu Bicheng and said: "I just mentioned optical communication, how is it realized?"
"Visible light communication uses high-frequency visible light to express 0 and 1 realize information transmission. This technology is called LiFi wireless network internationally. We plan to use it to replace WiFi and perform tasks in special environments."
Yu Bicheng explained simply.
"LiFi, WiFi..." After Yu Bicheng mentioned it, Chen Xing seemed to have vaguely heard it somewhere, but couldn't remember it.
He did not hesitate and asked: "Then what advantages does it have over WiFi?"
"It has higher transmission speed, higher security, and can resist electromagnetic interference. , abundant spectrum resources and low cost.”
Yu Bicheng just finished speaking and suddenly changed the topic: “But it also has disadvantages, that is, it has limited transmission distance and penetration because it is a direct line of sight. If it is completely blocked, the network will be disconnected, so it is highly dependent on the light source."
"But!"
He changed the topic again and said in a deep voice: "It is undeniable. This technology is of great research significance because its transmission speed reaches an astonishing 24GB/s!”
“His!”
Chen Xing took a breath.
As expected, technology has its advantages and disadvantages.
This "Visible Light Communication Technology" has extremely fast network speed and obvious advantages. However, the disadvantage is also obvious, that is, it is afraid of light source obstruction.
Is there development potential?
There is no doubt that there is.
Where there is light, there is a network. As Yu Bicheng said, it can be applied in special fields and may not be used commercially.
Thinking of this, Chen Xing immediately made the decision: "The "Terahertz Communication Technology" and "Visible Light Communication Technology" must be accelerated. In addition, the 6G network model must be accelerated. If you have any needs, please feel free to ask. As long as Longxing Group has it, we will do our best to satisfy you.”
As a technology company, Longxing Group is based on technology.
Since there is a new research project in the field of information and communication, it is impossible for him to say that he does not support it. Moreover, artificial intelligence does require high network speed for feeding and training.
“Understood.”
“Okay CEO.”
“Received.”
Deutschman, Yu Bicheng, Shen Sen, etc. People nodded in response.
Chen Xing looked at the time. It was already evening. He glanced at everyone and then said: "Then I won't disturb you. I'll go to the semiconductor chip floor to have a look."
Ternary chips, that's The artificial intelligence chip that he has been thinking about for a long time.
Although he knew that Gao Zhengqian could not successfully develop it so quickly, he also wanted to know where the project was at.
You must know Chen Xing's expectations for the ternary chip, but he gave it the name "Fuxi" and was waiting for the day it would become a blockbuster.
Seeing that Chen Xing was going to the chip floor, Doichiman also nodded slightly and said: "Mr. Chen, go slowly, I will successfully optimize the real 5G network as soon as possible and commercialize it around the world."
"We are the same, and we will do our best to develop "terahertz communication technology", "visible light communication technology", and "6G network large model". Please rest assured, CEO."
"Yes, use us The fastest speed."
Chen Xing watched Qian Yu, Shen Sen and others express their opinions one after another. He also raised a smile and responded: "Okay, I believe in your ability, but I still have to remind you. In a word, don’t be too tired, rest when you need to, because the body is the capital of revolution, let’s work together.”
