The unparalleled talent of the country started from Harbin Institute of Technology

Chapter 207, The Last Stand, -meter Signal (asking for monthly tickets)
May 11, 1982, was a Tuesday, the 18th day of the fourth lunar month, an auspicious day for getting married, traveling, cleaning, and getting engaged.

But Wang Duoyu is very busy and has no time to go out.

Charles Fefman and his team found Wang Duoyu in the morning and exchanged information about their respective derivation progress in recent times. In the afternoon, Ou Wenhui, head of Huaxing Chip, came to him to apply for funding.

Ou Wenhui did not come alone, but brought with him Han Jue, the executive vice president, and a leader from the Foreign Exchange Department.

Huaxing Chip Company needs to apply to purchase a batch of equipment. Ou Wenhui looks down on the backward equipment in China and wants to purchase it from abroad.

The purpose of establishing the chip factory is not only to produce chips, but also to produce the most advanced chips and various types of chips for Harbin Institute of Technology's cutting-edge technology products.

For example, the project department of Dolphin Corporation's handheld game console business needs to produce various types of chips.

For example, the computer in Wang Duoyu’s own office is also used every once in a while as long as Harbin Institute of Technology has more advanced technological products, such as the GT316 solid-state drive developed last month.

虽然GT316固态硬盘的容量仅仅只是20MB，但是其顺序读取速度高达5MB/s，且顺序写入的速度却达到了惊人的5MB/s，这一点可是比HS213的3MB/s强大得多了。

So Wang Duoyu also ordered fifty such solid-state drives.

The function of the GT316 solid-state drive is actually to be used as a cache disk or pre-processor disk for the mechanical hard drive. In short, such products have been developed, and there is no reason for Wang Duoyu not to use them.

So, to be honest, the tasks undertaken by chip factories are still very heavy.

However, the procurement plan proposed by Ou Wenhui involved a total of 18 million US dollars.

Such a funding amount is naturally not low, and Han Jue and the leaders of the Foreign Exchange Department are certainly unwilling to agree to it. So, Ou Wenhui came to Wang Duoyu to complain.

"Principal Han, Director Deng, I signed this document. It has my signature and seal. There can be no mistake."

Wang Duoyu said to Han Jue and Deng Zhangde in front of him with a smile.

The latter is a director of the Bingcheng Office of the Foreign Exchange Department, representing the opinions of the Foreign Exchange Department.

"Professor Wang, 18 million US dollars is too much, right? How about 5 million US dollars? You know, we..."

When Deng Zhangde heard this, he immediately groaned and started bargaining.

Even Han Jue followed suit and said:
"Yes, Duoyu, our school needs a lot of money, especially the three units of the Materials Science Research Institute that we just established a while ago. They've all submitted equipment purchase orders worth over 20 million US dollars. Secretary Liu and I are very worried."

It is undeniable that Wang Duoyu is very good at making money, but the five words "spending money like water" also truly describe him.

Just one chip factory will cost 18 million US dollars, and this is the third time to apply for funds. The previous applications were for 3 million and 5 million US dollars respectively.

It gives people the feeling that this is not 18 million US dollars, but 1,800 RMB.

The money was being spent too quickly, and Han Jue and the others couldn't keep up.

"Principal Han, I remember Secretary Liu told me before that no matter how much funding my project has, the higher-ups will directly approve it. And don't Secretary Liu and I already have our signatures on this document? Even Principal Lu has signed it. Is there anything else wrong?"

Wang Duoyu said softly, and seeing Han Jue wanted to speak, he raised his hand and said:
"I repeat, don't come to me with this kind of thing again. I know exactly how much $18 million is. The handheld game console we launched this year already generated $1.6 billion in revenue before March, and now it's over $2 billion. Don't we have $18 million left?"

"Principal Han, Director Deng, I have work to do. Please help yourself."

What a waste of his time!
Is it necessary to contact him many times for things like this?
Although there is nothing wrong with being cautious, Wang Duoyu has already signed, and Liu Deben and Lu Gongliang have also signed, so this document should be approved.

I didn't expect that the Foreign Exchange Department would get stuck. Tsk, why didn't their Foreign Exchange Department say anything when we were making money?
It is really better to use people who are forward-looking than to use people who are backward-looking!

Therefore, Wang Duoyu did not give Han Jue and Deng Zhangde a good look and directly ordered them to leave.

Not polite at all.

To be honest, Wang Duoyu didn't scold them, which was a sign of his good temper.

After Ou Wenhui, Han Jue and Deng Zhangde left, Wang Duoyu did not raise his head, but continued to busy himself with his own things.

The next day, Wang Duoyu came to a tiered classroom in the mathematics department's teaching building.

There are still many people here today because today is the monthly mathematics exchange hosted by Wang Duoyu.

The communication method is mainly for students to ask questions and Wang Duoyu to answer them.

Both Lu Ruoxi and Yuan Xueyi arrived at the classroom early and grabbed a relatively front seat.

It is obvious that they are not students of the mathematics department, and they don’t even understand mathematics very well, but they still want to grab such a good position.

But these have nothing to do with Wang Duoyu. He came here today to discuss mathematics with everyone, that's all.

However, at the beginning, it was John Milnor who asked the question, and his question confused most of the people in the classroom.

Because he asked a small question about the geometric Langlands conjecture.

Logically speaking, he is a Fields Medal winner and a researcher at the Ice City Institute for Advanced Study. He just communicated with Wang Duoyu the day before yesterday. Why is he here today and taking up everyone's time?

Moreover, the questions asked were so profound and too unfriendly to others.

One thing that is very clear to the global mathematical community is that Wang Duoyu successfully proved the Fermat conjecture using the Langlands proof of number theory using a relatively small set of functions.

As a result, there is a consensus in the mathematical community: the Langlands Program has an important position in three different mathematical fields: number theory, geometry, and so-called function fields! These three fields are connected by an analogical network, which André Weil called the Rosetta Stone of mathematics.

The third column of André Weil's Rosetta Stone concerns compact Riemann surfaces, including spheres, donut-shaped surfaces, and porous donut-shaped surfaces.

For a given Riemann surface, there is a corresponding object, called a fundamental group, which keeps track of the different forms of loops that can go around the surface.

At this time, John Milnor proposed the conjecture that the spectral side corresponding to the geometric Langlands should be composed of specific distillations of the fundamental group, which are also called representations of the fundamental group.

If the Langlands correspondence is to be represented in the geometric fields of the Rosetta Stone, then each representation of the fundamental group of the Riemann surface should be a frequency label.

John Milnor, Charles Fefman, and David Bryant Mumford have all failed to find any set of frequencies that appear to mark the characteristic functions of the fundamental group representation.

Two years ago, in 1980, Vladimir Drinfeld, a mathematics doctoral student in the Polar Bear Empire, proposed in his paper that it is possible to create a geometric Langlands correspondence by replacing the characteristic function with a more complex object called a characteristic layer.

However, at that time, Drinfeld only knew how to construct a few feature stacks.

“Maybe we can do this.”

Wang Duoyu, who was at the podium, began to write on the blackboard in response to the questions raised by John Milnor.

Various mathematical symbols began to appear, and except for Robert Langlands, Charles Feefman and others, most mathematics students, masters, doctoral students, etc., all looked confused.

Only a small number of people, such as Yang Nianzhen, Yorkz and others, can understand it, but they also have great difficulty understanding a very small part of the content.

As for Lu Ruoxi, Yuan Xueyi and other students or teachers who are purely from other departments, it is even more impossible for them to understand.

It’s just that these people are focused on participation and feel that Wang Duoyu is very awesome.

"In geometric Langlands, the frequencies of the characteristic layers are controlled by points on a Riemann surface, a sphere or donut where every point looks very similar at close range"

"But in number theory Langlands, the frequencies are controlled by prime numbers, and each prime number has its own unique properties, so how do we get from one prime to another in a nice way?"

Wang Duoyu spoke passionately on the podium, and John Milnor and others in the audience listened with great interest, nodding from time to time.

Finally, I finished speaking and it was finally other people's turn to ask questions.

The next questions were much simpler. Wang Duoyu only spent an average of five minutes to solve each question.

Because some issues need to be explained in detail, otherwise the audience will have confused expressions.

Today's exchange lasted two and a half hours, and the questions raised by John Milnor and others took up more than half of the time.

After the exchange, Charles Fefferman and the others took Wang Duoyu to the cafeteria to eat and chat.

Not long after arriving at the cafeteria, Wang Duoyu saw Qiu Chengtong with a smile on his face.

"Professor Wang, I'm back. Do you welcome me?"

Hearing what Qiu Chengtong said, Wang Duoyu stood up suddenly and asked in surprise:
"Professor Qiu, are you really willing to come to our Harbin Institute of Technology?"

This time, I am not coming to Harbin Institute of Technology as a guest like before, but I am joining Harbin Institute of Technology and becoming a professor hired by Harbin Institute of Technology.

Yes, Shing-Tung Yau is also willing to join Harbin Institute of Technology and will also serve as a researcher at the Ice City Institute for Advanced Study.

However, Shing-Tung Yau will not join the seven-member team to study the geometric Langlands conjecture.

Speaking of this matter, we have to start from the time when the sixth issue of "HIT Mathematical Journal" was published. Shing-Tung Yau and others came to HIT to communicate with Wang Duoyu.

At that time, Wang Duoyu persuaded John Milnor and his group for a long time, and finally a group of seven people were willing to stay in Ice City.

Yau also agreed at that time, but he needed to explain the reasons to his teacher Shiing-Shen Chern. On the other hand, he needed to return to the University of California, Berkeley to deal with his affairs and explain the matter to his wife.

Then why was Shing-Tung Yau willing to teach at Harbin Institute of Technology?

One is the general trend, and the other is the temptation of fame and fortune.

In fact, the second reason is the key point.

First of all, why is it the general trend?

In fact, after John Milnor and others agreed to join the Ice City Institute for Advanced Study, Qiu Chengtong's heart had already reassured him.

Here in Ice City, there is not only Wang Duoyu, a genius with excellent mathematical talent, but also top mathematicians such as Andrew Wiles, William Thurston, and Gerd Faltings.

Moreover, Wang Duoyu has verified that his teaching ability is indeed extraordinary. The six students including Yang Nianzhen have already made their mark. Perhaps within a year or two, these six people will be able to leave their own brilliant achievements in the global mathematics community.

On the other hand, the favorites for the 1982 Fields Medal were Wang Duoyu, Alain Connes, Shing-Tung Yau, William Thurston, Gerd Faltings, and Charles Fefman.

Although Shing-Tung Yau is quite confident that he will win the Fields Medal, the International Congress of Mathematicians has been postponed.

It won't be held until the middle of next year.

From April or May now to the middle of next year, there is probably more than a year left. Who knows what sudden changes will happen in the meantime?

Judging from the current situation, Wang Duoyu will definitely win a Fields Medal, and Alain Conne is also very confident.

But it is hard to say whether William Thurston and Gerd Faltings will come from behind and push Qiu Chengtong's third ranking down to fifth or even sixth.

Because both of them are in Harbin Institute of Technology and have been here for a long time, who knows if they will make any big moves in the future?

If William Thurston and Gerd Faltings suddenly get inspiration during their communication with Wang Duoyu and create a large satellite, then Shing-Tung Yau will really cry to death.

He, Shing-Tung Yau, was born in 1949 and is already 33 years old this year.

If he could not win the Fields Medal next year, then four years later in 1986 would be his time to make a final push.

However, it is conceivable that the competition for the Fields Medal in 1986 will be much more intense than next year.

why?
Because Wang Duoyu was born in 1956, he would most likely continue to verify those mathematical conjectures, and he might even win a Fields Medal in 1986.

Then there are three Fields Medal spots left, and Borchers, who is trying to prove the Magic Group Moonshine Conjecture, is very likely to reserve one.

There are also others such as Yorkz, Rong Guangxia, Yang Nianzhen, etc.

Therefore, for Shing-Tung Yau, the year in which he will be most likely to win the Fields Medal is next year.

As for 1990, he was already 41 years old at that time, and it was impossible for him to continue to win the Fields Medal. After all, this award is only for mathematicians under the age of 40 who have made significant contributions to mathematics.

Profit is not what Shing-Tung Yau pursues, but fame.

So in this era, does Shing-Tung Yau have any choice?
No!

His teacher, Shiing-Shen Chern, also disagreed with letting him go to Nankai University because Nankai University could not help Shing-Tung Yau.

Therefore, joining Harbin Institute of Technology is the best choice.

"Of course!" Qiu Chengtong said with a smile, and Wang Duoyu nodded immediately:

"Welcome, welcome. We warmly welcome you to join us. Have you eaten? If not, would you like to sit down and have a meal with us?"

"No, I came to look for you right after I got off the plane. They said you were in the cafeteria. Look, you just arrived."

"Haha, that's no problem. Sit down first. These are all your old acquaintances anyway. Let's sit down and have dinner together."

In this way, Shing-Tung Yau officially joined Harbin Institute of Technology.

By this time, although Harbin Institute of Technology's mathematical foundation had not yet been fully formed, it had already become the world's center of mathematics.

After all, the current Ice City not only has Wang Duoyu, a super mathematical genius whose talent far exceeds that of top mathematicians, but also eight mathematical researchers from the Ice City Institute for Advanced Study, including John Milnor, as well as Wiles, Thurston, Faltings and others.

It can be said that the mathematics in Ice City is now extremely strong.

In the entire Ice City, the most well-known university is Harbin Institute of Technology. Other schools in the Ice City seem even more dim under the brilliant light of Harbin Institute of Technology.

Of course, universities such as Bingcheng Shipbuilding Engineering College, Heilongjiang University, Northeast Agricultural College, and Northeast Forestry College also benefited from this. After all, after graduation, their students were directly arranged to work in units affiliated with Harbin Institute of Technology based on the principle of proximity.

Although college students of this era, especially those who have graduated or are about to graduate in 1977 and 1978, are very popular, who doesn’t know that Harbin Institute of Technology and its affiliated enterprises are the best institutions?
In the context of reform and opening up, a good unit is one that can make a lot of money.

Two days passed in a blink of an eye. On the morning of the 14th, there was only one day left before we set off for the trip tomorrow.

Wang Duoyu is obviously busier.

Yu Zhengze, director of the Department of Information and Communication Engineering, and Ao Xuanling, director of the Department of Electronic Science and Technology, came to Wang Duoyu, hoping that he could help solve the technical problems.

The Xiaolingtong project is located in the No. 2 Laboratory Building of Harbin Institute of Technology. Because it is a strictly confidential project, entry and exit are extremely strict.

Even Yu Zhengze and the others could not bring the technical information out.

Since it was a technical mathematical problem, Wang Duoyu asked Rong Guangxia and Yang Nianzhen to help after briefly listening to the problem.

Seeing this, Yu Zhengze and the others were still a little hesitant.

However, Wang Duoyu said that the two of them were enough.

You should know that the most important core technologies of Xiaolingtong are actually micro-cellular technology and dynamic channel allocation technology.

In communications engineering, it's all mathematics, especially signal processing.

It mainly involves mathematical tools, including Fourier transform, probability theory, random processes, coding, etc. For example, probability theory is used in the design and optimization of communication systems to provide a theoretical basis for analyzing and modeling noise, channels, and modulation schemes.

Linear algebra is used to solve the relationship between multiple variables.

Among Wang Duoyu's six students, Rong Guangxia and Yang Nianzhen are more inclined to the application of mathematics, and they usually participate in some scientific research projects of Harbin Institute of Technology.

Therefore, there is absolutely no problem for Wang Duoyu to let Rong Guangxia and Yang Nianzhen handle this matter at this time.

This is the advantage of Harbin Institute of Technology having a large mathematics team. As long as we encounter any mathematical problems, we can get support at any time, and it is very strong technical support.

Because mathematics is the foundation of all subjects and the basis of a building.

As long as mathematics is strong enough, other disciplines will surely develop rapidly.

After watching Yu Zhengze and the others leave, Wang Duoyu returned to his desk, looked down at his manuscript paper, and suddenly smiled.

On May 2nd, after returning from Beijing, he had been busy with the Mach 5 fighter project and had dealt with many things during this period.

However, this project has been implemented and most of the sub-projects have been built, but there is still no progress in the strong solution of the Navier-Stokes equations.

Theoretical derivation takes time, not to mention that this equation also needs to be combined with computational fluid dynamics simulation software, various experimental data, etc., so that it can be built up step by step like building blocks.

Now it seems that he can only wait slowly.

In other words, the two math problems he had chosen before, the strong solution of the Navier-Stokes equations and the geometric Langlands conjecture, which were of the eighteenth level of hell difficulty, had to be put aside for the time being.

The latter is to wait as long as possible to fully prove it, because Wang Duoyu wants to retain people like John Milnor and let them stay in Ice City for another one or two years, even for just a month, he hopes so.

Once people like Li Jun, Li Jianshu, and Rong Guangxia grow up, perhaps things will be much better.

Among Wang Duoyu's alternatives, there are people like Maxim Kontsevich, Vaughan Jones, Jean Burgain, and Zelmanov, who should also come to Harbin Institute of Technology to study and grow.

But now only Maxim, Vaughan Jones and Jean Bourgain are in Harbin Institute of Technology, and the others have not come yet.

This matter cannot be rushed, Wang Duoyu can only wait patiently.

As for the former, which is the strong solution of the Navier-Stokes equation, although Wang Duoyu is very anxious, he cannot be impatient.

Near lunch time, good news came from the cordless telephone project: the product of the project was finally successfully developed.

In August last year, the cordless telephone project was approved, and some professors and students from the two major departments of Information and Communication Engineering and Electronic Science and Technology were responsible for research and development.

Subsequently, these two departments recruited a number of teachers, including several professors from Xi'an Jiaotong University, Shanghai Fudan University and Guangzhou Sun Yat-sen University, all of whom are experts in radio technology.

Because cordless phones use radio technology, they convert voice signals into electrical signals, which are then transmitted using radio waves, and finally converted back into voice signals, ultimately enabling mobile communications.

This is the core technology of cordless phones. In addition, it also utilizes digital signal processing technology.

After all, cordless phones require the application of digital signal processing technology to achieve better communication quality and more communication functions.

Of course, current cordless phones have not yet implemented advanced communication functions such as text messaging and voice mail.

"Duoyu, you're here. Come on, come on. The cordless phone you were talking about is finally here. I really have to thank you so much."

Liu Deben, Lu Gongliang, Han Jue, Jin Lirong and others were already in the laboratory. This was the first time that Wang Duoyu met such a group of school leaders in a place like a laboratory.

The top, second and third in command are all here.

It's very rare.

"Secretary, Principal, you're here so quickly? Weren't you all out for the past few days? You're finally back today?"

Wang Duoyu greeted them with a smile and chatted with them politely.

The status of Harbin Institute of Technology has gradually changed, and the ambitions of Liu Deben and others have begun to expand.

Especially after the Ice City Institute for Advanced Study was successfully established, and John Milnor and his team of seven, plus the eighth top mathematician, Shing-Tung Yau, became researchers, Liu Deben and his team's ambitions grew even more.

As a science and engineering university, HIT offers a wide range of disciplines, including instruments, thermal energy, computer control, radio, electrical materials, chemical engineering, electromechanics, semiconductors, and business management.

However, this kind of professional setting is actually not comprehensive enough.

You should know that among the colleges and universities across the country, there are as many as 204 engineering majors, 70 science majors, 55 agricultural majors, 57 medical majors, 20 forestry majors, and 48 finance and economics majors.

Let’s forget about liberal arts, sports, art, and teacher training, because Harbin Institute of Technology is a science and engineering university, and the humanities and social sciences fields only have a few majors such as business management, not many.

Liu Deben and his colleagues’ idea is that Harbin Institute of Technology should cover all majors in engineering and science, and also set up majors related to medicine and finance, so as to truly cover all important areas of science and engineering.

The categories of engineering are very broad. For example, mechanics majors include theoretical and applied mechanics and engineering mechanics.

However, Harbin Institute of Technology currently does not have some related majors in materials, such as powder materials science and engineering, materials design science and engineering, composite materials molding engineering, etc.

In other words, Liu Deben and his colleagues hope to set up these comprehensive majors, but their superiors may not agree.

The reason is quite simple. Society may not necessarily need so many talents in unpopular professions. On the contrary, in the context of reform and opening up, there is an even more urgent need for talents with professional skills.

Take Huashun Company as an example. Its factory produces optical disc storage, HS213, GT216 and other products. All of these products require a certain technical foundation and at least a high school degree, preferably a bachelor's degree.

After all, products like optical disc storage are new technologies, and ordinary high school graduates really cannot understand them.

In the history of the original time and space, our country implemented the technical secondary school policy in 1984. The background was due to the needs of economic construction and social development. Students were recruited from junior high school students, with a school system of three years, and some for four years, mainly to cultivate intermediate technical talents.

If Harbin Institute of Technology wants to set up more majors and cultivate more high-end talents that are relatively unpopular but needed by society, it must obtain approval from above.

But how can it be so simple?
Therefore, Liu Deben had to go to the capital in person, and Lu Gongliang was also forced to get busy.

After exchanging a few words with Liu Deben and the others, Wang Duoyu finally saw the cordless telephone.

"Professor Chen, can this phone provide normal voice communication within a range of 300 meters?"

After fiddling with the cordless phone for a while, Wang Duoyu looked at Chen Baoxi, the project leader.

Upon hearing this, the latter immediately responded:

"Yes, Professor Wang, there's absolutely no problem. We've completed numerous tests. Even if there's a wall between the cordless phone and the landline, as long as the wall is no thicker than 15 centimeters, the communication signal won't be affected."

"We've also tested the communication quality of this cordless phone, and it all meets the technical requirements you set forth."

"Because you mentioned the multi-carrier format earlier, there are a total of twelve carriers, each with a bandwidth of 1.728MHz. Each carrier is divided into time slots in the time domain, and a duplex connection can be established using two of these time slots."

"Once a call is established, the cordless phone uses one-eighteenth of its time to transmit and receive, leaving the rest of the time free for other tasks, such as monitoring other frequencies and carriers for a better voice channel."

"Also, the Department of Information Science and Engineering helped develop a hybrid integrated circuit that handles source coding, channel coding, encryption, and channel modulation. The power management module dynamically adjusts the power consumption of each component of the entire system, minimizing overall power consumption."

These are all technical optimizations, and are also the optimal solution products after cooperation with various project departments.

Chen Baoxi's explanation also revealed the reason why the cordless telephone was successfully developed in less than nine months.

Harbin Institute of Technology is no longer the Harbin Institute of Technology it was in 1978 when Wang Duoyu first joined the university.

"So the software for this phone was also developed with the help of the Department of Information Science and Engineering?"

Lu Gongliang followed up with a question, with a hint of surprise in his expression, especially after seeing Chen Baoxi nod.

In late February last year, the Department of Computational Mathematics of Harbin Institute of Technology applied for a split, but the split has not yet been completed.

In early March, Lu Gongliang arrived at Harbin Institute of Technology and began to take over the position of president of Harbin Institute of Technology. At that time, he happened to catch up with the work of splitting up colleges and departments.

As the president, although Lu Gongliang was not very familiar with the Department of Computational Mathematics of Harbin Institute of Technology before, he knew that Wang Duoyu, a world-renowned mathematician, was in this department.

After the split, Wang Duoyu stayed more in the Department of Mathematics. Although the Department of Information Science and Engineering has six major majors, in Lu Gongliang's opinion, it is definitely not as important as the Department of Mathematics.

But no one would have expected that Wang Duoyu attached no less importance to the Department of Information Science and Engineering than to the Department of Mathematics.

This made Lu Gongliang even more confused. It was obvious that the Department of Mathematics was more important, and Lu Gongliang used to be a professor in the Department of Mathematics and Mechanics at Peking University. Of course, he was more aware of the importance of mathematics.

But today it seems that he may not understand the Department of Information Science and Engineering very well.

This department is not as simple as it seems.

"The software includes the application layer, data link control layer, and media access control layer," Chen Baoxi continued.

Wang Duoyu waved his hand and said:
"Okay, no need to introduce all this, let's start the test now. I want to experience it myself."

This is a new product, so Wang Duoyu naturally wants to experience it himself. If there are no major problems, he can immediately use such a product in his office and home.

Although this product is more targeted at the overseas market, it is not sold much in China.

But even so, issues such as quality safety and call quality need to be resolved.

If you don’t even trust the products you develop, how can you expect consumers to buy them?
So, in the following time, Wang Duoyu tested this cordless phone.

The test results were indeed as Chen Baoxi said. In open areas, the call quality within 300 meters was very clear.

In a place like home, there is no problem standing on the balcony, but if you stand in the room, the signal will drop sharply.

Because the wall obstruction is still very serious. After all, the wall thickness of the houses near Harbin Institute of Technology is generally more than 24 centimeters, so the call quality is not very good.

If it is in the southern region, the thickness of the walls there is less than 15 centimeters. In this case, if the host is in the living room and the cordless phone is taken into the room to answer the call, the signal should not be too bad.

In this case, this product can also be sold.

why?

Because in Europe and America, especially in the United States, most of their houses are simple wooden houses, not to mention the thickness of the walls, which are less than 15 centimeters.

There may be some houses with walls that are thicker than 15 centimeters, but not many.

And this is not a big problem. I can upgrade the signal quality of the cordless phone later.

As for technology, it can definitely be improved and updated.

"Duoyu, what's a reasonable price for this phone?" Liu Deben asked immediately.

When Wang Duoyu mentioned this project last year, he knew that cordless phones were used to earn foreign exchange, so he was very concerned about the pricing of this product.

Lu Gongliang, Han Jue, Chen Baoxi and others all looked at Wang Duoyu, who pondered and did not respond immediately.

In the history of the original time and space, Motorola will launch the world's first commercial mobile phone 8000X in April next year, with a price of up to US$3995.

But this is a mobile phone, which is completely different from a cordless phone.

As for the commercial cordless telephones of the original time and space, they only appeared in the 1990s and are not of reference value.

Even so, after thinking about it, Wang Duoyu gave this reply:

"The price of this cordless phone is set at $1982. We'll see how the market reacts. If sales are average, we'll proactively lower the price. We won't be cutting the price directly, but we'll offer a buy-one-get-one-free deal or a free phone with a top-up."

Directly lowering the price is definitely a very low-end method. On the contrary, recharging the phone bill, for example, directly recharging 3,000 US dollars, will give you a cordless phone.

In this way, it would be perfect to directly cooperate with those American telecom operators.

Because after April next year, Motorola's commercial mobile phones will definitely be on the market, and once they are on the market, they will inevitably have an impact on the sales of cordless phones.

After all, in 1973, Motorola laboratory engineer Martin Cooper successfully made the world's first mobile phone call.

After so many years of development, Motorola has set up many base stations across the United States, so commercial mobile phones are ready to be put on the market.

Even though it is priced at $3995, which is very expensive and it is a big square box, for many consumers, a mobile communication device is still very necessary.

They are both mobile communications. Although cordless phones are pseudo-mobile communication devices, they are still mobile communications and can be considered the same market. Of course, they will be impacted by Motorola mobile phones.

After hearing Wang Duoyu's suggestion, Liu Deben and others remained silent and carefully thought about the pricing.

Chen Baoxi also said at the right time:
"Secretary, President, Professor Wang, the current cost of our product is 500 RMB, but this is the laboratory cost, not including other investments. If it were a factory, we are confident that the cost can be reduced to less than 300 RMB."

The cost is still too high.

But many devices of this era, especially imported equipment, are very expensive as long as they have something to do with high technology.

Cordless phones involve many technologies such as digital signal processing, so their cost is naturally not cheap.

In such an era, Chen Baoxi can still be so confident that he says he can reduce the cost to less than 300 yuan, which shows that he is still very confident.

Wang Duoyu nodded and said:

"Okay, no problem. Next, you guys should prepare for mass production as soon as possible. Motorola's cell phones are basically confirmed to be released next year. If we launch a cordless phone this year and it sells well, they might even release it earlier. So we have to be fully prepared."

Chen Baoxi nodded repeatedly to show that he understood.

After walking out of the laboratory, Liu Deben called Wang Duoyu and returned to the latter's office, obviously to continue chatting.

"Duoyu, how many cordless phones do you think we can sell?"

"Secretary, I can't say anything about this kind of speculation about sales volume," Wang Duoyu shook his head.
"We priced it at $1982 per unit, which is actually quite expensive. But for many Americans, they are very willing to try new things, and this is indeed a very advanced high-tech product. For them, that's enough."

"I can't guess the exact sales volume, but almost every household in the United States has a telephone installed. If only one percent of them are willing to replace their cordless phones, the sales volume will not be low."

"In my opinion, scientific research institutions, universities, government offices, etc., they will definitely be very happy to replace such technological products, because Americans are lazy."

After hearing what Wang Duoyu said, Liu Deben immediately understood.

After all, this cordless phone is very different from previous products and the cost is a bit high. If the sales volume fails, he will still be very worried.

Now that Wang Duoyu analyzed it this way, it was indeed the case. If that was the case, he was not so worried anymore.

Immediately, Liu Deben mentioned another matter.

PS: Please vote for me!
