Technology company, I will become the light of China!

Chapter 299: Satellite base station module, the finance of major countries is in a hedging situation!
Daoyichman, Shen Sen, and Yu Bicheng suddenly rushed back, causing Chen Xing to pause and say, "It's not too late, we just arrived."

"That's good."

Shen Sen breathed a sigh of relief.

They were exhausted from the two days of overtime work. They originally planned to finish dinner and go back to the apartment to rest early. Unexpectedly, someone reported that Chen Xing led someone straight to the information and communication laboratory.

Shen Sen, an old man, knew very well that he could make up for it at any time, but the premise was that the leader Chen Xing must be satisfied.

While the two were talking, Ren Wanzhou looked carefully at Doichiman, Shen Sen and Yu Bicheng. These were important engineers of the International Telecommunications Union (ITU), and Kunpeng Company was looking for them.

At the same time, she also lamented that the United States took the lead in establishing the GCOT global telecommunications alliance and took away a large number of Western engineers from the ITU International Telecommunications Union. Now that Chen Xing is developing 5G networks and has taken away a group of engineers, the ITU International Telecommunications Union is still in name only. .

While Ren Wanzhou was stunned, Chen Xing asked Doichiman: "Professor Doichiman, Chief Qian said that the satellite base station technology has been conquered. Is it convenient for a demonstration?"

While speaking, Chen Xing glanced at Ren Wanzhou and Ren He beside him.

The meaning I want to express is very obvious, which is to show it to them.

The third satellite base station, in the low orbit area, is responsible for sending signals.

"What a genius idea." Ren Wanzhou couldn't help but admire in his heart. Deutschman is worthy of being the founder of the fourth generation of information and communications. His ideas and thinking are top-notch.

"Anyone who has studied geography knows that the thermal layer is above 85 kilometers. The air here is thin, the ultraviolet radiation is intensified, there will be no clouds and lightning, let alone rain, so there are no factors that interfere with the signal."

The construction of base stations does not just require access to the Internet, there are also cost issues to consider.

A second satellite base station, in the mid-orbit area, is responsible for signal processing.

Just like holding a magnifying glass in summer, you can focus the scattered sunlight into a point to achieve the effect of concentrated beam.

Technology is nonsense regardless of cost.

For a 4G network, two satellites are enough, but the millimeter waves of the 5G network are too delicate and require the cooperation of a third satellite base station.

"Please come this way."

Deutschman has entered his twilight years and is a well-informed authority in the field. He can naturally understand Chen Xing's subtext.

The moment he said these words, he suddenly changed the topic and said with a touch of pride: "But we still overcame this problem!"

The second medium-orbit satellite is an ordinary communication satellite, responsible for receiving signals, processing the signals and sending them back to the ground.

Deutschmann took two steps forward.

He paused for half a second, took a breath and continued: "Low-orbit satellites can range from 200 kilometers to 2000 kilometers. If they exceed that, they are medium-orbit satellites."

Ren He was no longer calm.

This means that nine satellites can allow the people of the entire eastern Guangdong Province to experience the 5G network. The coverage area is a bit too large!
While Chen Xing was surprised, he was already silently calculating the launch cost.

For example, the base station built by Kunpeng Company, the macro base station is priced at 1 million to 3 million, and the micro base station is also available in the hundreds of thousands. The coverage area of ​​the two in the city is only a few kilometers. You can see the base station at any intersection. Antenna box.

After Doichiman's explanation, Chen Xing has roughly understood the principle.

I saw him coming to a piece of equipment and patiently explaining: "5G networks are extremely vulnerable to external interference, such as reinforced concrete walls, clouds, fog, rain, thunder and lightning."

With the launch vehicle technology currently exposed by Longguo, it can send two satellites at a time, nine satellites, six low orbits, and three medium orbits. It needs to launch five launch vehicles. The single cost is 2.5 million, One billion can complete network coverage in eastern Guangdong Province.

"With the current ground base station construction technology, the maximum coverage range is only about 20 kilometers, and it needs to be built in an open area without obstacles. However, the signal transmission and reception distance of our satellite base station is ten times that of existing technology!"

"What does 200 kilometers mean?"

Even Ren Wanzhou flashed a hint of surprise.

There are 34 provincial-level administrative regions in Longguo. Based on an average of 2.5 million, it means that it will cost 5 billion to build comprehensive 85G network coverage in Longguo.

After Chen Xing and others reviewed the draft, Deutschman continued to explain: "As you can see, our satellite base station is composed of several parts."

The satellite base station is not just one, but three satellite base stations. Although the draft is only a rough drawing, everything that should be drawn is drawn.

The third low-orbit satellite is equivalent to a magnifying glass, receiving the data signal of the medium-orbit satellite, amplifying the intensity of the millimeter wave, and allowing it to return to the ground smoothly.

"I have a question, and I would like to ask Professor Deutschmann for advice." At this moment, Ren He, the general manager of Kunpeng Company's base station construction, came half a step forward and expressed his doubts:

"The low-orbit satellite base station is equipped with signal capture equipment toward the ground, which is also commonly known as the satellite pot. It is responsible for capturing ground signals in an ultra-low orbit of 200 kilometers, and then uses it as a relay station to send the signal to the center. Orbital satellite base station.”

"I don't know yet, but according to my estimation, three satellite base station modules can build a cellular network in eastern Guangdong Province."

"When the signal is captured by a medium-orbit satellite, it will analyze it using high-speed algorithms and send the signal to the third satellite. Since then, data upload, data processing and data download have been completed, forming a network."

Chen Xing was also curious.

Chen Xing took it and observed it carefully.

"What I want to ask is, when building such a satellite base station module, taking a group of three as an example, what is its actual coverage?"

If the construction coverage area is only a few kilometers, but it takes three satellites to build a network, it will be a fool's errand. Even if Longxing Technology is sold, it will not be able to build this network.

Because there were drawn arrow instructions, Chen Xing understood it easily, and Ren Wanzhou and Ren He also vaguely understood the principle.

"Look at this design drawing." Deutschman picked up a few rough drafts on the table and handed them to Chen Xing.

"Three?"

"Of course, these are not the most difficult to overcome. The technology that satellite base stations need to overcome most is distance."

The first satellite base station, in the low orbit area, is responsible for receiving signals.

The first low-orbit satellite was equivalent to the current base station on the ground. Its function is to receive signals and send them out.

It would cost 85 billion to cover the Dragon Kingdom, but what about covering the whole world?

"Astronomical figures."

Chen Xing sighed silently in his heart.

He didn't dwell too much on it, because this was just his rough estimate, and he hadn't asked about the cost of the launch vehicle. Maybe he didn't need so much money at all.

Faced with Ren He's surprise, Deutschmann smiled and said: "This is the best arrangement to ensure network speed. If only 4G network is used, a single group of satellites can cover it."

With a base station hanging 200 kilometers above your head, its reception range is like a person standing on the top of a mountain, and the field of vision will naturally be wider.

In order to let Chen Xing and others understand the satellite base station more intuitively, Deutschman also demonstrated it with laboratory instruments.

After figuring out the principle and witnessing the demonstration again, Ren Wanzhou nodded slightly and exclaimed: "This idea is so genius. Perhaps only Professor Deutschmann can come up with it. This is a masterpiece that changes the existing base station pattern. I found it I salute you from the bottom of my heart.”

"No no no."

Doichiman waved his hands repeatedly and looked at Yu Bicheng beside him and said: "This is not the credit of me alone, but the credit of the entire team. In fact, this idea was first thought of by Yu Xiaoyou. I just perfected it. .”

"It was all taught by Professor Deutschman."

Yu Bicheng also waved his hand.

Although he is usually carefree and has the energy of a young man, he still respects the seniors in his field very much.

In addition, he has not forgotten the first rule of scientific research, which is not to compete with his predecessors for credit.

No matter which field you are in, you can go a step further by being sociable. Talents with low EQ, if they don't meet Bole, will often lament in the corner that they are full of talents but have no place to use them. Chen Xing saw the "concession" of the two people, and he didn't have the money to bother him. He glanced at Shen Sen and Qian Yu and asked, "Are you sure there is no problem with this technology?"

In addition to further confirmation, his words were also meant for Ren Wanzhou, because currently only Kunpeng Company has the corresponding base station equipment, and they need to build the prototype of the satellite base station.

Qian Yu and Shen Sen looked at each other. After making eye contact, they both said in unison: "In terms of theory, the technology is mature."

"That's okay." Chen Xing looked at Ren Wanzhou again and said, "The communication technology conditions have matured. Wanzhou, when do you think the prototype of the satellite base station will be built first?"

According to Chen Xing's idea, Kunpeng Company is responsible for the base station signal part of the satellite base station. As for the satellite part, Chen Xing has already discussed it with Zhao Chenguang and can just take it directly to the Changxi Rocket Launch Center for assembly.

Don't think that the Chauncey Rocket Launch Center only launches rockets. It also has the Chauncey Satellite Research Base.

"The principle of this base station satellite is not complicated. The specific construction time of the prototype depends on the actual situation." Ren Wanzhou did not give an exact time because it was the first time to build a base station satellite and she wanted to leave room for herself.

"Just two days."

Ren He suddenly spoke.

"Two days?"

Chen Xing's pupils flashed with surprise.

Ren He nodded and responded: "Three days at the latest. The base station part is not very complicated. I think the difficulty should be the satellite part."

"We have a way to solve the satellite part. Let's do this. Chief Engineer Ren, please leave your contact information with Chief Qian. If you have any technical problems, keep in touch at any time."

Chen Xing introduced the two of them.

"I can't ask for it."

"I'll scan you."

Qian Yu and Ren He added WeChat.

After knowing the principle of the satellite base station and the specific manufacturing ideas, Ren Wanzhou and Ren He did not think about it too much and said one after another:

"In order to catch up with the progress, we will go back first and come back to visit Mr. Chen in two days."

"I'd like to say goodbye first, Mr. Chen."

Facing the two people's farewells, Chen Xing also nodded slightly and said: "Pay attention to safety on the road. If there is any progress, you can contact Chief Qian or me directly."

"Ok."

After a brief polite exchange, Ren Wanzhou and Ren He took the elevator, left the R&D building and headed to the parking lot.

Just after returning to the car, Ren Wanzhou looked at Ren He, the driver, and asked with some confusion: "The base station part can be completed in two days?"

"Maybe if you work overtime, you can." Ren He started the vehicle lane.

He was actually holding his breath in his heart. He had worked hard to build the Batie Base Station brick by brick. Those grandsons in the West blew it up when they asked, and even injured his own people. After he came back, the more he thought about it, the more he couldn't believe it. strength.

Now that he had the opportunity to retaliate indirectly, he would not let this opportunity pass him by.

"Buzz-"

His phone suddenly vibrated twice.

While driving with one hand, Ren He took out his mobile phone to check WeChat messages.

It was a technical document sent by Qian Yu. After briefly scanning it, he put down his phone and concentrated on driving back to Kunpeng Base.

……

And at the same time.

the other side.

Across the ocean, New York, USA.

Due to the time difference, when Dragon Kingdom was shrouded in darkness late at night, a new day had just begun here.

New York Stock Exchange.

Shareholders are already in place collectively.

Their enthusiasm is high and they are all full of confidence in the stock market.

Not long ago, the Federal Reserve of the United States once again announced an adjustment in deposit interest rates, from a maximum of 5% to 7%. This made the global capital flow back even more fiercely. In just one hour, trillions of dollars flowed into the United States.

Where will the money go?

stock market!

Will money be copied when placed in the bank?
The answer is no!
The interest that depositors receive is basically a fraction of what the bank earns from investing.

After being pointed out by financial bloggers, American stock investors not only did not withdraw their money, but also invested it in the stock market, because they knew very well that the influx of large amounts of money would inevitably cause the stock market to rise continuously.

as predicted.

As rice stocks open again.

Nvidia?
rise!
Apple?

rise!
Gaotong Company?
rise!
Unlike the stock markets of other countries, the stock market of rice stocks did not fall, but only surged. The two formed a sharp contrast.

The continuous surge in rice stocks has also made foreign investors unable to help but feel excited. They converted their investments into U.S. dollars, which intensified the return of U.S. dollars.

No one knows when this farce will end, but what is certain is that now even fools can make money in rice stocks.

……

Longguo Securities Regulatory Commission.

The village chief, Xiao Gang, had not slept for two days. After seeing rice stocks skyrocketing again, he finally recognized the reality.

The U.S. dollar's interest rate hike is not just about meat, it is about destabilizing global finance and making the world pay for the United States.

What exactly does it mean?
The Asian financial crisis in 1997 was caused by the inflation of the U.S. currency, which led to the collapse of the global financial system.

After the global stock market plummeted, Wall Street giants bought a large number of high-quality assets at low prices, such as Korean Star Group and TSMC...

Now that he has made a comeback, he has also raised the interest rate to 7%. The first day has been so difficult, and it will be the second day soon. Xiao Gang really doesn’t know how to save the city, unless there is a big release...

In addition to the frustration of the head of the China Securities Regulatory Commission, the president of Bank of China also has a headache.

The interest rate hike on the U.S. dollar led to the outflow of domestic funds. In less than two days, hundreds of thousands of people exchanged U.S. dollars for foreign exchange.

Although it is clearly stated that it cannot be used for investment, if someone entrusts the money when they go out, how do you supervise it?

The most important thing is that the US dollar interest rate hike has also led to the withdrawal of foreign funds from the stock market. Now if Longguo retail investors want to take out their money, the Bank of China can only lower the deposit interest.

One side is raising interest rates and the other is cutting interest rates, creating an arm-wrestling hedging situation. Now it really depends on who can't bear it first.
