Chapter 312 This Is the Infrastructure Maniac

Chapter 312 This is the infrastructure maniac!

"Hello, leaders, seniors, and juniors, I am an information and communications engineer assigned by the government to the ITU International Telecommunications Union. My name is Shen Sen, and I currently work in the information and communications laboratory of Longxing Technology Company."

Longxing base.

Conference room in 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 live broadcast. The target audience of the live broadcast service is not ordinary people, but a group of highly respected academicians, 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. For example, 10 engineers in the communications field are paired with 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.

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

"Expert Shen, you're welcome. Since we're under heavy pressure from above, let's get to the point as soon as possible. How to build satellite base stations."

An academician urged me.

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, three satellites. Their main functions 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 capturing equipment on the ground to ensure that ground signals can be received smoothly."

"Selection of signal capture equipment. The signal capture equipment we currently use is the ZC-7 provided by Kunpeng Company. At the same time, a high-frequency antenna must be added at the other end of the satellite, which is also an HX-3 model antenna provided by Kunpeng Company. , to ensure that the signal can be successfully received by Satellite 2, which is the 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.

He pushed up his black-rimmed glasses and asked with soul torture: "What do you mean, if we want to build a satellite base station, we need to prepare the signal capture equipment and high-frequency antenna produced by Kunpeng Company first?"

"Yes, not entirely right." Shen Sen smiled and responded: "I don't mean you have to use Kunpeng Company, as long as the power is about the same, but it is better to use Kunpeng. Military planes arrived last night. A batch has been shipped and I believe you can see the assembled parts within today."

"I see."

Chen Jinhua nodded.

"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 2,000 kilometers. Why not put the medium orbit satellites Lower it? For example, lower it to 500 kilometers. I feel like this can save the need to install high-frequency antennas."

"Yes, I have this doubt too."

Another academician echoed.

At this time, they were like returning to their student days, constantly asking questions to the teacher Shen Sen, but this also played into Shen Sen's wish, because by asking questions and solving them, they could build a satellite base station for the 5G network more rigorously.

"This is a good question. Why does Satellite 2 use 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 into it. You guys, start developing satellite base stations together."

"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 the processing of four or even six low-orbit satellites. "

"Understood."

The academician who asked the question nodded.

To put it bluntly, this mid-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 No. 1 will use high-frequency antennas to transmit the signals collected from the ground, please note that the medium-orbit satellites must also be equipped with signal capture equipment and high-frequency antennas, and they are on the same surface... "

…

Because it is a new field of integration, the 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 couldn't explain it, Dao Yiqiman would personally go out and give a standardized explanation.

Academicians from the Long Kingdom were collectively taken into classes. 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 communications do not understand satellites, and those who understand satellites do not understand information and communications. As for those who understand them, they do not understand millimeter wave communication technology.

Online classes have become 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 amazing."

"Continue testing."

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

"Sure enough, it is 5.7MB/s. The network speed test passed. You can take the interference test. As long as it is not less than 3MB/s, it will pass."

"Turn on jamming equipment."

"Opened."

While the teams of Chen Qiang and Li Erwen were intensively testing, 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.

In the afternoon.

"Answer sheets" were handed in one by one.

Dautschman, 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 to pass!

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

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

If outsiders know that he is a prostitute, it doesn't matter. If they know, they 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, the Pang-20 began to transport the satellite base station again to the nearest rocket launch center.

besides.

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 lines have been canceled to ensure the efficiency of military aircraft.

Some passengers originally complained about the sudden suspension of the plane, but when they saw Pang-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's rear." How do you fight this?"

[Upright 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 have their aircraft and warships, and we have recruits. It's enough. Really, we’re not envious at all.”

"If there is a war, we will be recalled" was released in the early morning, and the Fat-20 "national tour" was filmed during the day, which made countless people excited.

However, some bloggers pointed out the announcement issued by the Longguo Space Agency and refuted the "Knives Out" rumors.

Unfortunately, the popularity of the topic was too low, or the popularity of "Knives Out" was too high, so not many people saw it.

Netizens from the Dragon Kingdom were excited, and Neon netizens who were living a good life next door were panicked. Who didn't know that the two families had an indelible hatred. If the "knife came out of the sheath", there was no need to analyze too much about who would be the first to kill.

Xiao Baga, who is somewhat afraid of death, has already bought a flight 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, Neon Island 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!

Maybe they also know that Mount Fuji will erupt one day, or that it's really hard to sleep and eat next to the big Eastern country, so it's better to stay away.

In addition to the Neon Island Country, netizens in countries such as the Yue Monkey Country, the Ancient Elephant Country, and the Peninsula are a little bit restless, for fear of being hit by flash attacks.

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. Dragon Kingdom seems to be holding a large-scale, but non-explosive, fireworks show. Satellites are being launched one after another. The base station is sent to the 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 place 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 overthinking.

Long Guo had no time to pay attention to them and just quietly worked 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 Jiangsu and Zhejiang provinces. Please report the network connection status."

"This is the Ministry of Communications of Jiangsu and Zhejiang. It has been detected that there is 5G network signal coverage. The first network speed test is in progress. Please wait."

Five minutes passed.

"The report shows 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."

"receive."

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%..."

"receive."

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

"Reporting to the main station, the 5G network signal connection in Hui'an Province 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 going to Changxi and the whole country was mobilized. Dragon Kingdom has actually started large-scale construction of satellite base stations. Is this the speed of an infrastructure maniac?"
