Technology company, I will become the light of China!

"Mr. Chen, you are kidding me, right? Has Gaotong really signed a contract with us to share 4G network technology?"

Doichman's eyes flickered with surprise.

He is eighty-nine years old this year. Age, to a certain extent, represents experience, so he considers himself knowledgeable and 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 over Gaotong to get it to sign a technology sharing contract for the 4G network?
Although age represents experience, it also has its disadvantages, which is that it is difficult for him to accept new things. In addition, he was in a foreign country and had no idea about Gaotong's infringement.

"Professor Doichman, you don't know that some time ago we found that Gaotong Company infringed the "DSP Multi-core Architecture Technology". This is just the compensation obtained through legitimate rights protection negotiations." While Chen Xing explained, he looked at Qian Yu, Shen Sen and Yu Bicheng, as if wondering why they didn't tell Doichman.

Isolate yourself?
Probably not!
"During this period, Professor Doichman has been optimizing the algorithms for 5G networks day and night, and we are also working on the overall architecture of 6G networks. We don't have much time to interact with each other on weekdays."

Qian Yu began to explain.

His words were still quite implicit.

Although they all work on the same floor, there are dozens of independent laboratories on this floor.

to be honest.

It is a laboratory for specialized fields.

This is like classmates in college. Even if they are in the same class, it is impossible for everyone to know each other, because after entering college, everyone is busy with their own things.

"That's true." Shen Sen responded and continued, "I have been busy with tasks recently and have no time to share information. I will pay attention to this issue in the future."

"The main reason is that everyone is very busy, so it's normal that there is little communication. By the way, Mr. Chen, does that mean that we can now use Qualcomm's 4G network technology?" Doichman came out to smooth things over, not wanting the atmosphere in the lab to become dull.

“Yes, all are available.”

Chen Xing nodded in response.

It's not that he's making a fuss about the fact that Deutschman didn't know about Qualcomm's infringement. The main reason is that Deutschman is almost 90 years old, and it's obviously unrealistic for him to get information on the Internet by himself. Someone must share the information.

After all, they came all the way to Shenzhen to help Longxing Group develop 5G high-speed network, but in the end, they knew nothing about it except for scientific research. This is a bit too disheartening.

However, they didn't dwell on this topic. After Chen Xing reminded them, they changed the subject:

"Our contract clearly states that Gaotong must unconditionally and permanently authorize Party A, that is, our Longxing Group, to use technologies related to 4G communication networks, such as "CDMA digital technology branch spread spectrum communication technology", "OFDMA multiple access technology", "MIMO multiple input multiple output", and "OFDM orthogonal frequency division multiplexing".

"This is good!"

There was a flash of excitement in Doichman's eyes.

The main reason why they are unable to develop a true 5G high-speed network is that they cannot get around Qualcomm’s patents.

Anyone who has done scientific research knows that technology has the characteristic of being able to expand and develop.

For example, some technologies of 4G network can be applied to 5G network.

If you choose to bypass it and choose other methods instead, your Internet speed will most likely be greatly reduced.

Why did Deutschman say that Longxing Group was not developing 5G network, but 4.5G, 4.6G or 4.7G?

The problem is that some network technologies cannot be circumvented, or if circumvented, the 5G network speed will be greatly reduced and will not meet the ideal requirements.

To give another example, why have high-end automobile engines, such as eight-cylinder or sixteen-cylinder engines, not been domestically produced yet?

Four words: patented technology!
Patent certificates for internal combustion engines can be stacked up for hundreds of meters. When you are halfway through research and development, you will inevitably infringe on other companies. If they do not agree with your use of the technology, you can only circumvent it. If you can circumvent it, the performance will be greatly reduced. If you cannot circumvent it, then you will not be able to manufacture it, let alone put it on the market to make money.

Qualcomm's network technology may not have brought much improvement to 4G networks, but it is an indispensable piece of the puzzle for 5G networks.

"There is no need to bypass key technologies, and the real 5G network can be successfully launched." Yu Bicheng said with excitement.

"Then we can put aside the 6G network for now and improve the 5G network first."

Qian Yu suggested.

"That's exactly what I was planning." Shen Sen clenched his fists, ready to do something big.

According to their original prediction, the maximum speed of this "pseudo 5G network" independently developed by Longxing Group was 70MB/s. Now, everything is uncertain.

"You don't need to put down your work, just leave it to me and my team." Deutchman volunteered.

Upon hearing this, Qian Yu asked with concern, "Is it really possible? Will the workload be too large?"

"Yes, we can't rush the 6G network. If the workload is too large, we can work together to optimize the 5G network first."

Shen Sen echoed.

The 6G network requires a redesign of the system network structure. According to their idea, they want to create a "three-layer and four-side" 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, network, spectrum, and various special facilities.

The network function layer is the logical function layer of the 6G network core and is the main body for realizing 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 and application enablement frameworks, thereby achieving unified application enablement management.

As for the four sides, they are the control plane, user plane, data plane and intelligent plane.

It is conceivable how much manpower, material resources and time are required to develop the 6G network, and they are not in a hurry.

"I appreciate your kindness. In fact, I have already designed an internal test version of the 5G network model." Doichmann suddenly revealed his cards.

Chen Xing: "???"

"what?"

Yu Bicheng and others were stunned.

Now don’t say that Chen Xing was stunned, they didn’t know that Doichman had this trick, and there was even a beta version!
"For comparison and to more intuitively see the limits of 5G networks, I made two models, one that does not bypass technical barriers, and one that we have already applied."

While Doichman was explaining, Chen Xing suddenly had an idea and asked, "So, the 70MB/s you mentioned was calculated based on another 5G model?"

"Yes."

Doichman nodded and continued, "Because Gaotong has mastered so many mature information and communication technologies, it is definitely the best to use their technology, so I made a comparison model."

"According to my initial test, under the same optimization conditions, the 4G network model designed using Qualcomm's 5G extension technology can increase the network speed by 30% to 91MB/s!"

"I see."

Chen Xing suddenly realized what was going on. He looked at Doichman and said, "No wonder you often mentioned Gaotong's 4G network technology to me. It turns out that it has already been tested privately."

Since patent applications require the disclosure of principles, it is not difficult to replicate it privately.

As for patent rights, as long as you don't use them for public commercial purposes, no one will know if you use them privately.

This is also why only business talks about patents, but there are no so-called patents in the military field.

"That's right. We now only need one optimization update to replace the immature technology and make the 5G network more stable and faster." Doichman nodded and replied.

Qian Yu, Yu Bicheng and others were not surprised. It was no secret that the laboratory used registered patented technology privately, as long as it was not used publicly for commercial purposes.

"Thank you for your hard work in optimizing the 5G network, Professor Deutchman."

"no problem."

Doichman answered directly.

Due to his lack of talent, he is unable to participate in the research and development of 6G networks and can only focus on 4G and 5G networks.

"correct."

Chen Xing thought of something and looked at Qian Yu and Yu Bicheng and said, "I heard you talk about 6G network. What are the advantages of this generation of information and communication technology?"

"The coverage of 6G network is too wide." Shen Sen took a step forward and continued to explain: "To put it simply, it has a higher speed, lower latency, and greater connection density than 5G network. The most important thing is that it can fit your artificial intelligence, Mr. Chen."

"Big Data?"

Chen Xing was stunned.

"That's right!"

Shen Sen nodded and responded: "It is big data. Moreover, we have discovered two new spectrum communication technologies, namely Terahertz Communication and Visible Light Communication, which have great research value."

"Terahertz, visible light spectrum communication..." Chen Xing was confused. This was a new technology that he had never heard of.

As if seeing Chen Xing's confusion, Qian Yu explained, "You may be unfamiliar with terahertz, but if I say its name in the field of optics, far-infrared light, you will definitely be familiar with it."

"Far infrared light?"

Chen Xing was stunned again.

Of course he knew about far-infrared light, which was widely used in optical products.

Some criminals also use it in health care products and devices, claiming that it can cure all kinds of diseases, deceiving a large number of consumers.

"Well, it has multiple names. In the field of optics, it is called far infrared light. In the field of electronics, it is called submillimeter waves. In our field of information and communications, it is called terahertz."

Qian Yu took a breath and continued, "Terahertz refers to electromagnetic waves with a frequency range of 0.1-10 THz. It is between millimeter waves and infrared light, and is neither completely applicable to optical theory nor to microwave theory."

"According to our preliminary technical prediction, once terahertz communication technology is realized, the maximum wireless transmission speed can reach 9GB/s."

"9GB?"

Chen Xing was stunned again.

He originally thought that 6G network should still be measured in MB, but he didn't expect that GB would be used to express the network speed.

What does 9GB/s mean?
A two-hour Japanese movie with high-definition and lossless image quality is only about ten or twenty GB. Even if the file size is 30 GB, with the speed of 6G network, wouldn’t it be downloaded in the blink of an eye?

"Yes, that's 9GB/s!" Yu Bicheng also responded, and then continued: "As long as the terahertz communication technology is initially realized, we will become an unshakable giant in the field of information and communication, and truly crush the world!"

"This... this is more than just a world-beater. It feels like it can even realize real-time interstellar communication." Chen Xing thought to himself.

The advent of 6G network technology is not just a small technological shock, but a revolutionary shock like nuclear fusion and room-temperature superconductivity!
"What's the current progress?"

Chen Xing suppressed his excitement and asked.

"It is still in the early stages. The 6G network is not just a project of our information and communication laboratory. Other laboratories are also needed to participate." Yu Bicheng responded while mentioning other laboratories.

"Oh?"

"Need other laboratories?" Chen Xing continued to listen attentively.

"Yes, we need assistance from other laboratories." Yu Bicheng confirmed again and explained patiently:
"Because terahertz communication is a brand-new information and communication technology, more efficient signal transmission and reception technology is required, including frequency conversion circuits, mixers, frequency multipliers and amplifiers."

"At present, the output power and operating frequency of our equipment and devices cannot meet the commercial requirements of low power consumption, high efficiency and long life."

"It doesn't need to be used commercially. As long as we can use it for ourselves, it will be considered a success." Chen Xing said quickly.

6G network commercial use?

This is a commercial egg!
The maximum network speed is 9GB/s. Even if Chen Xing dares to put it for commercial use, will users dare to use it?
Don’t do as the joke goes, forgetting to turn off the internet before going to bed, and waking up with a phone bill that costs the entire capital.

6G network is not suitable for commercial use, but is suitable for internal research and development.

"If it is not commercially available, the standards can be lowered, but we still need to wait for a specific reply from the chief executive of the chip laboratory."

Qian Yu suddenly mentioned Gao Zhengqian.

"Chief Gao?"

Chen Xing looked puzzled.

Qian Yu: "RF devices that can meet the requirements of terahertz communication require new semiconductor materials. We have talked to Chief Gao, and he said that silicon germanium and indium phosphide may be used to manufacture new RF devices. Let us wait patiently for his reply."

"So that's it."

Chen Xing suddenly understood.

No wonder the West is racking its brains and trying so hard to restrict semiconductors. It turns out that this field has such extensive connections.

CMOS sensors in the optics field and RF devices in the information and communication field both require technical support from the semiconductor field.

"So what is this visible light communication?"

Chen Xing asked again.

He originally wanted to come here to report the good news to the Information and Communication Laboratory, but he didn't expect these top engineers to give him a big surprise.

"Visible light communication is a more advanced communication technology than terahertz. It can provide Internet access wherever there is light."

Yu Bicheng's words are shocking.

Doichman was also shocked.

Is the new generation of communication technology so abnormal?
Terahertz can achieve GB-level transmission speeds, and optical communications can achieve optical coverage. Are these technologies definitely in the communications field?
"How did you do it?"

Chen Xing showed some interest.

(I want to climb step by step)

(Waiting for the sun to look at its face quietly)
(Small sky has big dreams)
The ringing of the cell phone interrupted the communication in the laboratory.

Chen Xing took out his cell phone and found that it was a call from the security booth.

"Someone's visiting again?"

While he was mumbling in his heart, he answered the call and asked, "What's the matter?"

"I'm sorry, President. I may have disturbed you. The thing is, there is a man at the entrance of the base who claims to be the chairman of the FSA Financial Services Agency of the island country. His name is Saito Ii. He wants to talk to you about something. He also showed relevant documents."

"Island country's FSA?"

Six words flashed through Chen Xing’s mind: the island country’s Securities Regulatory Commission.

Each country has a different name for the Securities and Exchange Commission, which is caused by cultural differences, but the scope of authority and jurisdiction is similar.

"Yes."

Security reconfirmed.

"If the people from the island country's FSA Financial Services Agency come to my door, then it must be about Nikkei 225." Chen Xing thought to himself and responded directly: "Send them away."

"what?"

Security was confused.

He had been there for such a long time, but this was the first time he saw Chen Xing directly chase someone away, and the two of them had never even met each other.

However, Chen Xing also had his own reasons. That was that the chairman of the island country's FSA Financial Services Agency came to his house just to ask Longxing Group to let go of Nikkei 225 and stop shorting and engaging in commercial competition.

But is this realistic?
Obviously, unrealistic.

In the past, when Japanese companies occupied a dominant position, you could restrict the export of photoresists and semiconductor equipment, and even raise prices from time to time. Now that the offense and defense have changed and the polarities have reversed, can you let them go easily?
By shorting Nikkei 225, Chen Xing can get what he wants, and if all goes well, he can also control the company he wants.

Peace talks?

Go dream!

"Just say I'm going out and send him away." Chen Xing gave a random reason.

"Oh okay, I know."

After the call was hung up, the security guard looked at Saito Ii, who was dressed in a suit and tie, and said, "Our president is still out there doing business. You guys should go back first."

As soon as the words fell, the translator beside Saito Ii immediately translated them into Japanese.

After hearing this, Saito Jing's face instantly darkened. He returned to the car with a gloomy face, then looked at the driver and said, "Let's go back to the hotel."

"Back? He's obviously there."

The driver asked.

When the Gaotong Company negotiation team entered, they had actually already arrived and had been observing from a distance.

Gaotong stayed in there for such a long time, and Ren Guofei also drove away, which means that they have definitely finished their discussion. In other words, Chen Xing is definitely in the Longxing base.

Even if Chen Xing was not at the Longxing base, the security should not have had this attitude. At least there was a vice president who came out to greet him and show courtesy. They were from the island country's FSA Financial Department. The only one who could make the security order them to leave was Chen Xing.

"Chen Xing doesn't want to talk to us. Now we can only contact the relevant departments of Longguo and ask what's going on."

Saitoi's tone was threatening.

You should know that the island country's capital has invested a lot in Longguo. For example, many of its car companies are joint ventures with Japanese companies.

For example, Internet companies such as Penguin and Alibaba all have island capital shareholders, and they are major shareholders.

Saito Jing’s idea now is very simple. Since Chen Xing doesn’t want to see him, he will find a middleman to introduce him and eventually turn hostility into friendship.

"So that's it."

The driver suddenly realized what was going on and then backed out of the Longxing Group headquarters base.

……

Information and Communication Laboratory.

After Chen Xing hung up the phone, he looked at Yu Bicheng and said, "We just talked about optical communication. How is it achieved?"

"Visible light communication uses high-frequency visible light to express 0 and 1 to achieve 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 this, Chen Xing seemed to have vaguely heard it somewhere, but couldn't remember where.

He didn't hesitate and asked, "What are the advantages of it over WiFi?"

"It has the advantages of higher transmission speed, higher security, resistance to electromagnetic interference, rich spectrum resources and low cost."

Yu Bicheng had just finished speaking when he suddenly changed the subject and said, "But it also has disadvantages. That is, the transmission distance and penetration are limited. Because it is a direct line of sight connection, if it is completely blocked, the network will be disconnected directly, so it is highly dependent on light sources."

"but!"

He changed the subject and said in a deep voice: "It is undeniable that this technology is of great research significance because its transmission speed reaches an astonishing 24GB/s!"

"hiss!"

Chen Xing took a breath.

Sure enough, all technologies have advantages and disadvantages.

This "Visible Light Communication Technology" has extremely fast network speeds and its advantages are very obvious, but its disadvantages are also obvious, that is, it is afraid of being blocked by the light source.

Is there potential for development?

Without a doubt, there is.

Where there is light, there is a network. Just as Yu Bicheng said, it can be applied in special fields, not necessarily for commercial use.

Thinking of this, Chen Xing immediately made a decision: "We need to speed up the development of Terahertz Communication Technology and Visible Light Communication Technology, and we also need to speed up the development of the 6G network model. If you have any needs, please feel free to ask. As long as Longxing Group has them, we will do our best to meet your needs."

As a technology company, Longxing Group relies on technology as its foundation.

Since there are new research projects in the field of information and communication, it is impossible for him to say that he does not support it. Besides, artificial intelligence does require high Internet speed for feeding and training.

"understood."

"Okay CEO."

"receive."

Doichman, Yu Bicheng, Shen Sen and others nodded in response.

Chen Xing glanced at the time. It was already evening. He glanced at everyone and said, "Then I won't bother you. I'll go to the semiconductor chip floor to take a look."

The ternary chip is the artificial intelligence chip that he has been dreaming of.

Although he knew that Gao Zhengqian would not be able to succeed in the research and development so quickly, he also wanted to know the progress of the project.

You should know that Chen Xing had high expectations for the ternary chip and named it "Fuxi", just waiting for the day when it would become a hit.

Seeing that Chen Xing was going to the chip floor, Doichman nodded slightly and said, "Mr. Chen, take care. I will optimize the real 5G network as soon as possible and commercialize it worldwide."

"We will also devote all our efforts to the research and development of Terahertz Communication Technology, Visible Light Communication Technology, and 6G Network Model. Please rest assured, President."

"Yes, at our fastest speed."

Chen Xing watched Qian Yu, Shen Sen and others express their opinions one after another. He also smiled and responded, "Okay, I believe in your abilities, but I still want to remind you not to get too tired. Rest when you need to, because your health is the capital of the revolution. Let's work hard together."
