The next day, Ye Fei and others returned to Zhonghu University after spending a few days in Jakarta.

After returning to Zhonghu University, Ye Feizheng was preparing to continue research on Gaussian conjecture.

But that afternoon, Ye Fei was called to the office by the principal.

After entering the office, Ye Fei saw a middle-aged man sitting in the office.

The principal was chatting with a middle-aged man and didn't notice Ye Fei walking in.

Ye Feidao: "Principal!"

When the two heard the sound, they looked at Ye Fei at the same time. The principal smiled and said: "Ye Fei, here you go, sit down quickly."

After Ye Fei sat down, the principal personally poured tea for Ye Fei and said, "Ye Fei, let me introduce to you. This is Academician Ning from the Institute of Wireless Communication Technology of the University of Electronic Science and Technology of China."

"Academician Ning, this is Ye Fei."

Academician Ning smiled and stretched out his hand: "Professor Ye, hello, I am Ning Zhi."

"Hello!" Ye Fei stood up, stretched out his hands, and shook hands with Academician Ning.

"Professor Ye, your name has been famous to me for a long time. Others say you are a mathematical genius."

Ye Fei quickly waved his hand and said with a smile: "In front of you, Academician Ning, I don't dare to be a mathematical genius. The title of mathematical genius is also flattered by others. You can't believe it!"

Ye Fei didn't know about Academician Ning's deeds, but to become an academician, he must be a master in some fields.

In front of such an outstanding person, Ye Fei respected him in his heart.

Academician Ning nodded, he liked such low-key people.

There are too many great people and too many geniuses in the academic world.

In such a circle where great people gather, if you want to stay around for a long time, you must keep a low profile.

If you are too high-profile, others will dislike you and make you suffer. This is also a very common thing.

Therefore, in academic circles, the more capable you are, the more you should keep a low profile.

Academician Ning said: "Professor Ye, do you know about Li-Fi?"

"Li-Fi?" Ye Feidao: "Of course I know this. Li-Fi is visible light wireless communication, also known as optical fidelity technology. It is a new wireless transmission technology that uses the visible light spectrum for data transmission."

"Invented by German physicist Professor Harald Haas, chairman of the Department of Mobile Communications, School of Electronics and Communications, University of Edinburgh, England."

"I'm right!"

Academician Ning nodded and said: "That's right. It seems that you have some understanding of Li-Fi."

Ye Fei smiled and said: "That's not the case. When Li-Fi came out, I was still in high school. When I had nothing to do, I liked to use my mobile phone to surf the Internet and see a lot of news."

“I happened to see the news about Li-Fi at that time.”

Li-Fi was developed in 2015, when Ye Fei was a sophomore in high school.

Academician Ning shook his head amusedly: "This kid is so honest."

Academician Ning said: "Ye Fei, I am studying Li-Fi, and we are encountering technical difficulties now."

"Huh?" Ye Fei frowned and said doubtfully: "Academician Ning, doesn't Li-Fi have a fatal flaw? Why are we still conducting research on it?"

"Even if it is researched, it will not be popularized because of this fatal flaw!"

"Of course I know this." Academician Ning said: "The reason why I studied it is to know if I can use other methods to remove the fatal shortcomings of Li-Fi."

"After all, Li-Fi's network speed is a hundred times that of Wi-Fi."

“If we can remove the shortcomings of Li-Fi and retain its advantages, we can make Li-Fi popular.”

"Then our country can lead the world in wireless communications."

"The most important thing is that we can also develop new IEEE standards and no longer need to pay money to the Wi-Fi Alliance."

"You also know that our country is the largest Internet market in the world. There are many people using the Internet and many people using Wi-Fi."

Anyone who uses Wi-Fi must pay a certain fee every year.

If Wi-Fi is used 365 days a year, the handling fee paid by each person per year may only be about ten yuan.

But the Xia Kingdom has a large population, with Internet users reaching 1.1 billion.

800 million of them are using Wi-Fi.

There are 800 million people, and each person pays about ten yuan a year, which is 8 billion a year.

“Every year, our country alone pays nearly 10 billion to the Wi-Fi Alliance.”

"If the country uses this money for other things, the country can do a lot of things."

"Even if we don't use it for other purposes, if we reduce or waive Xia's handling fees, we can increase the people's savings!"

"Of course!" Academician Ning said with a smile: "In the eyes of many people, ten yuan may not be enough for a meal."

"But a dime is still money, Professor Ye, don't you think so?"

Ye Fei nodded.

"And!" Academician Ning said: "If we can really popularize Li-Fi, then we can also charge fees from other countries around the world."

"There are six billion Internet users in the world. Excluding Xia's 1.1 billion, there are still 4.9 billion Internet users, of which 3 billion are using Wi-Fi."

"Then we can charge at least 30 billion in handling fees every year."

"Moreover, with Li-Fi's network speed, we can also increase the handling fee appropriately."

"The network speed of Li-Fi is a hundred times that of Wi-Fi, so it is appropriate to charge a handling fee of 30 yuan."

"So, this is equivalent to collecting nearly 100 billion in handling fees every year."

"One hundred billion is a huge amount of money for any country, and it can do a lot of things."

"The most important point." Academician Ning suddenly said seriously: "You know that our country has 5G technology."

"At this point, Beili has always wanted to limit the development of 5G."

Ye Fei nodded.

"So, Beili is studying Wi-Fi7."

We are currently using Wi-Fi6. The network speed of Wi-Fi6 is 5GHz and the network speed of Wi-Fi7 is 30GHz.

"If Wi-Fi7 is developed, then 5G will be limited."

"Because of this, I studied Li-Fi to counter Wi-Fi7."

"As long as Li-Fi is successfully developed, it will be useless even if Beili Country develops Wi-Fi 7."

"Because, Wi-Fi has lost its function."

"So, Li-Fi is too important to Xia Guo."

Ye Fei understood. Since Xia State has the largest number of Internet users in the world, it also uses the most Wi-Fi.

But the money the country gives to the Wi-Fi Alliance every year reaches nearly 10 billion.

If Xia Guo creates Li-Fi, not only can he formulate IEEE standards, he can also save nearly 10 billion in handling fees and earn nearly 100 billion in handling fees from the world.

The most important thing is that it can counter Wi-Fi7 so that 5G can no longer be blocked.

Therefore, Li-Fi is very important to Xia Guo.

Ye Feidao: "Academician Ning, what do you want me to do? As long as I can do it, I will definitely promise you."

Academician Ning smiled and said, "Okay, I'm just waiting for your words."

"Then I'm not welcome."

"Academician Ning, please don't be polite." Ye Fei said seriously: "As long as I don't die, you can use me as hard as you can."

"Haha..." Academician Ning and the principal looked at each other, then laughed.

Academician Ning smiled and said: "Professor Ye, it's not that serious. I just need you to do research, and I don't want to kill you."

Academician Ning suddenly said seriously: "Professor Ye, I heard that you are very good at short pulse technology. Is that true?"

"Yeah!" Ye Fei nodded: "I once helped Kyoto University provide support for short pulse technology in lasers."

"I also participated in the research of ground-based anti-satellite laser weapons, in which short-pulse technology was used extensively. The short-pulse technology was mainly researched by my team."

This is a confidential project, and the identities of all researchers must be kept confidential.

But that was during research. Now that the research has been successful, the confidentiality level has been lowered a lot.

As academician Ning, he can know.

"So, I am very good at short pulse technology."

Academician Ning said in surprise: "This is really great. As you know, in terms of network communication, the main research is on short pulse technology to find suitable pulse channels so that network communication can transmit data on the pulse channels."

"Yes!" Ye Fei nodded: "When I was studying short pulse technology, I also conducted some research on network communications."

"If you want to speed up the Internet, you actually need to use an extremely wide spectrum in a shared way."

"That's right!" Academician Ning nodded: "The data appears on the spectrum. People who use the network can retrieve the shared data from the spectrum at any time."

The relationship between spectrum, data and pulses is equivalent to that the spectrum is the road, the data is the vehicle, and the pulse is the motor that drives the vehicle.

Afterwards, Ye Fei and Academician Ning had some exchanges on network communications.

In terms of network communication, Ye Feiran is far inferior to Academician Ning. He just talks about the knowledge he knows and adds some inspiration.

In the eyes of many people, Ye Fei is half a layman.
