Chapter 312 This is the infrastructure maniac


Chapter 312 This is the infrastructure maniac!

“Hello leaders, seniors, and juniors, I am an information and communication engineer assigned by the government to the ITU International Telecommunications Union. My name is Shen Sen, and I am currently working at Longxing Technology. The company's information and communication laboratory work."

Longxing Base.

Conference room in an office building.

Facing the camera being broadcast live, Shen Sen seemed a little cautious, rubbing his hands back and forth under the table.

To be honest, this is his first time to live broadcast. The target of live broadcast service is not ordinary people, but a group of highly respected academicians, as well as university professors or doctors.

Because it was a live broadcast of the conference software, Shen Sen even saw a few familiar faces, teachers who had taught him before.

For the construction of satellite base stations, national think tanks also have corresponding plans.

First, they are divided into working groups, such as 10 engineers in the communications field and 10 engineers in the satellite field to form a group. Each group selects two team leaders. The team leader listens to the lecture and records the technical points. The other engineers are mainly responsible for the work. live.

To put it bluntly, it is the scientific research team model.

"Expert Shen is very polite. Because the pressure from above is tight, let's get to the point as soon as possible. How to manufacture satellite base stations."

An academician urged.

It may be that they are involved in a new field, and they are a little anxious.

Those who can become academicians must either have excellent talents or work ten times harder than others. None of them are simple.

"Okay, let me get straight to the point."

Shen Sen adjusted his posture, moved his chair, and then explained: "The satellite base station is divided into three parts, that is The main functions of the three satellites are roughly divided into receiving signals, processing signals and transmitting signals. "

"The No. 1 low-orbit satellite is responsible for capturing ground signals. We need to install signal capture on the ground. Capture equipment to ensure that ground signals can be received smoothly. ”

“Selection of signal capture equipment. The signal capture equipment we currently use is ZC-7 provided by Kunpeng Company, and it is also on the other end of the satellite. It is necessary to add a high-frequency antenna, also an HX-3 antenna provided by Kunpeng Company, to ensure that the signal can be successfully received by the No. 2 satellite, which is a medium-orbit satellite. "

"Wait for Expert Shen."

At this time someone interrupted Shen Sen’s lecture.

His name is Chen Jinhua, an academician of information and communications at the Imperial Academy of Sciences and a distinguished professor at Fuda University.

I saw him pushing up his black-rimmed glasses and asking in soul torture: "What you mean is that if we want to build a satellite base station, we need to first prepare the signal capture equipment and high-end equipment produced by Kunpeng Company. Frequency antenna?”

“Yes, not entirely right.” Shen Sen smiled and responded: “I don’t mean you have to use Kunpeng’s, as long as the power is about the same, but it’s better to use Kunpeng’s. It's better. A military plane arrived last night and shipped a batch. I believe you can see the assembled parts within today."

"That's it."

Chen Jinhua clicked. nod.

"I also have a question." Just after Chen Jinhua finished asking, another academician asked: "Why are the satellite base stations two low and one medium? As far as I know, the low orbit area is 200 kilometers to 2000 kilometers. Why not lower the medium-orbit satellite? For example, lower it to 500 kilometers. It feels like this can save the installation of high-frequency antennas.”

“Yes, I have this doubt too.”

Another academician echoed.

At this time, they felt like they were back in their student days, constantly asking questions to the teacher Shen Sen. However, this played into Shen Sen’s wish, because only by raising questions and solving problems can we create a more rigorous 5G network. Satellite base station.

"This is a good question, why is Satellite 2 in a medium orbit instead of a low orbit." Shen Sen repeated the question, and then continued to explain:

"That's because Satellite No. 2 builds a cellular network in the sky. When satellite No. 1 or No. 3 in low orbit enters the area of ​​other Satellite No. 2, it will automatically connect."

"For example, I am in Shenzhen City, I am Satellite No. 1, and you are Satellite No. 2. Because I am in Shenzhen City, I cannot help you share the work personally. But when I enter your R&D base, I will integrate with you and start research and development together. Satellite base station. ”

“Of course, the reason for this design is to avoid performance waste. The current algorithm of Satellite 2 still has a lot of room for improvement. In the future, we plan to have one Satellite 2 responsible for four. , or even the processing of 6 low-orbit satellites.”

“Understood”

The academician who asked the question nodded.

To put it bluntly, this medium-orbit satellite is a ground base station in the sky. Any satellites No. 1 and No. 3 entering the area can connect to it and then quickly perform signal processing.

If it is set in the low orbit area, it will affect the future satellite layout.

"If there are no questions, then we will continue." Shen Sen asked, but no academician responded to him.

Seeing this, he continued to explain: "When Satellite 1 will collect signals from the ground and transmit them using high-frequency antennas, please note that the medium-orbit satellites must also be equipped with signal capture equipment and high-frequency antennas, and It’s on the same side..."

...

Because it is a new field of integration, communications academicians and satellite academicians listened very carefully and did not dare to miss a single detail.

Not only Shen Sen lectures, Yu Bicheng and Qian Yu also teach in the conference room next door and provide remote guidance.

As for Deutschmann, he is responsible for answering difficult questions raised by academicians.

As long as Qian Yu, Shen Sen and Yu Bicheng can't explain it, Dao Yiqiman will personally give a standardized explanation.

Academicians from Long Guo were collectively taken into class. No one would believe this if told. This is simply unbelievable.

But there is nothing we can do about it. Those who understand information and communication do not understand satellites, and those who understand satellites do not understand information and communications. As for those who understand both, they do not understand millimeter wave communication technology.

Online classes are online classes, and the effect is still very significant. At the Imperial Satellite R&D Base, Information and Communications Academician Chen Qiang and United Satellite Academician Li Erwen took the lead in developing a satellite base station and entering the testing phase.

“First test.”

“5.7MB/s, is this a 5G network? It’s really awesome.”

“Continue testing.”


"It's still 5.7MB/s, very stable. It should be the same value for the third time. After all, we are so close to Satellite 2."

"It is indeed 5.7MB/s. The network speed test passed and interference can be detected. Tested, as long as it is not less than 3MB/s, it will pass. ”

“Turn on the interference device”

When Chen Qiang and Li Erwen’s team were busy testing. At that time, other academicians also entered the testing process one after another. As long as they understood the principles, their efficiency was still very high.

After all, none of the engineers who can come here are simple.

Even if you are a handyman, you will be treated as a guest when you go to work in a university.

“The connection test is stable and meets the minimum standards. I think it can be submitted for review.” An engineer from Chen Qiang’s team suggested.

However, for the sake of rigor, Chen Qiang conducted a second test. After confirming that there were no problems, he submitted the obtained scientific research data to Deutschman for review.

Afternoon time.

"Answer sheets" were handed in one by one.

Deutschman, Shen Sen, Yu Bicheng and Qian Yu transitioned from the role of teachers to the role of examiners, reviewing and approving "answer sheets". Because so many talents have been brought together, and the Longxing Technology Information and Communications Group has given their full support, the passing rate has reached 100%!

Being able to have a 100% pass rate is not only due to the extremely high standards of the academicians, but also the invisible BUFF blessing of "face".

With so many colleagues in the industry gathered here, it would be embarrassing if something went wrong or failed!

It is not terrible to lose face in front of outsiders, but the most terrible thing is to lose face in the industry.

This is like being caught soliciting prostitution. Not only must you be detained and fined, but your family must also be notified. Who can stand this?

It doesn’t matter if outsiders know that you are a prostitute. If you know, you will know. But if family members, such as parents, brothers and sisters know, it is different. It is a proper social death.

Because they are afraid of not being able to survive in the industry, academicians are extremely rigorous, fearing that something will happen and their reputation will be completely lost.

They can guarantee that this is the most serious and rigorous time they have ever taken.

In addition to the rigorous academicians, the Fat-20 transport aircraft are also not idle. The Southern Military Region directly dispatched ten Fat-20 transport aircraft to collect Kunpeng Company's base station parts and transport them to satellite research and development bases in various places.

In the evening, Pang-20 began to transport the satellite base station again to the nearest rocket launch center.

Beyond that.

It is also responsible for transporting rocket components.

Today is the busiest day for Fat-20, and it is also the most leisurely day at airports everywhere.

Due to line congestion and to ensure the speed of transportation, most civil aviation routes have been canceled to ensure the efficiency of military aircraft.

Some passengers originally complained about the sudden suspension of flights, but when they saw Fat-20 running back and forth, as well as the revelations and hot searches on the Internet, they suddenly lost their temper.

……

Weibo information platform.

"Fat-20 National Tour?" 》The entry occupies the top of the hot search list. When you click on the entry, you will see photos taken by netizens.

[Radiant]: "Picture.jpg, Fat-20 was photographed again at the Imperial Capital International Airport. This round belly, this iconic big face, isn't he really mobilizing his troops?"

[Mahua smiles]: "Picture.jpg, look at it, it was taken at Sichuan-Chongqing Airport. It's so handsome. It's a 200-ton transport aircraft. This is a transport aircraft that can carry tanks. If there was such a thing in World War II, tanks could be parachuted directly to the enemy." How do you fight in the rear? "

[righteous and awe-inspiring]: "Picture.jpg, located in the west of Guangxi. As a former armed police soldier, I really don't envy the Air Force and Navy at all. You guys have nothing to do with it. It is enough for us to have recruits for our aircraft and warships. Really, we are not envious at all.” "This made countless people excited.

However, there are also bloggers who pointed out the announcement issued by the Longguo Space Agency and refuted the rumors of "Knives Out of the Sheath".

But unfortunately, the popularity of the topic is too low, or the popularity of "Knives Out" is too high, so not many people saw it.

The netizens of the Dragon Kingdom are excited, and the Neon netizens who are living a good life next door are panicking. Who doesn’t know that the two families have an indelible hatred? Requires too much analysis.

Xiao Baga, who is somewhat afraid of death, has already bought a ticket to Brazil.

Perhaps many people don’t know that while the Neon Island Country is developing rapidly, it is also constantly purchasing land from other countries.

According to public information, the Neon Island Country has purchased more than 1.2 million square kilometers of permanent land in Brazil.

What is the concept of 1.2 million square kilometers?

This is equivalent to 3 times the current land area of ​​Neon Island Country!

Perhaps they also know that Mount Fuji will erupt one day, or that it is really difficult to sleep and eat next to the big eastern country, so it is better to stay away.

In addition to the Neon Island Country, netizens like the Yue Monkey Country, the Ancient Elephant Country, and the Peninsula are a little bit restless, for fear of being hit by lightning strikes.

When the whole world focused its attention on the Dragon Kingdom, late at night, the first Yuanzheng-3B carrier rocket also took off, followed by the second, and the third...

Changxi, Quanjiu, Shanyuan, and Changwen Rocket Launch Centers are all launching carrier rockets. The dazzling firelight illuminates the dark night sky. Longguo seems to be holding a large-scale, but non-explosive, fireworks extravaganza. The satellite base station is put into a predetermined orbit.

In just two hours, the total number of rockets launched has reached more than 30, almost without interruption.

This "rocket feast" has also made the whole world extremely nervous, especially the Neon Island Country and the United States. The latter has even entered a wartime state and mobilized aircraft carriers to assist in defense.

Because no one can predict whether one of these launch vehicles will carry an intercontinental missile carrying mushroom eggs.

If more than a dozen mushroom eggs were carried, considering the size of the island country, no one would be spared.

Therefore, as long as the launch of the Dragon Kingdom does not end for a moment, the top leaders of the Neon Island Kingdom will not dare to sleep for a moment, and the same is true for the American troops stationed on the island. Some of them have even prepared their last words in advance.

However.

They are obviously worried too much.

Dragon Kingdom has no time to pay attention to them, it just silently works on its own infrastructure.

Shencheng Longxing Base.

Inside the Information and Communications Laboratory.

Qian Yu was conducting a satellite docking test and asked about the situation: "The sixth group of satellite base stations have been successfully docked, covering the area of ​​Jiangsu and Zhejiang provinces. Please report the network connection status."

"This is Jiangsu and Zhejiang." The Ministry of Communications has detected 5G network signal coverage and is conducting the first network speed test. Please wait."

Five minutes have passed.

“Reported that the 5G network signal connection in Jiangsu and Zhejiang Province is stable, the network speed is 5MB/s, the weather is good, and there are no interference factors.”

"Received."

Qian Yu nodded, changed provinces, and asked again: "The seventh group of satellite base stations has been connected. The coverage area is Ganxi Province. Please report the network connection status."

"Reporting to the main station, the 5G network signal connection in Ganxi Province is stable, the network speed is 3.2MB/s, the weather is bad, there is heavy rainfall, there is a north wind of level 5, and the humidity is 68%..."< br>
"Received."

"The eighth group of satellite base stations has been docked and covers the area of ​​Hui'an Province. Please report the network connection status."

"Report to the main station , Hui'an Province's 5G network signal connection is stable..."

While Qian Yu asked about the situation, Shen Sen kept recording data beside him.

According to the 5G network coverage plan, first the south, then the east, then the center, then the north, and finally the west, which is determined based on population density.

On the other side of the ocean, in the United States, Speaker Renato Marotta fell silent as he looked at the reports and documents that were constantly being submitted.

“How long has it been since?”

"Less than two days have passed since Chen Xing was photographed heading to Changxi and the whole country was mobilized. Dragon State has actually started large-scale construction of satellite base stations. Is this the speed of an infrastructure construction maniac?"
