Chapter 283 “Four” Difficulties of Satellite Base Stations

Deep City Dragon Kingdom.

Longxing Bantian Base Headquarters.

Perhaps because of the construction of the "satellite base station", Ren Guofei did not bring a driver, but asked Ren Wanzhou to drive.

Thanks to the greetings and the popularity of Ren Guofei's face, the vehicle did not need to go through the cumbersome security inspection process and drove directly to the R&D building.

Ren Wanzhou glanced at the road sign, then turned his attention to the surrounding environment of the Longxing base and sighed: "I didn't expect that Longxing Technology built the base in just over a year. It is really too fast."

"Yes."

Ren Guofei also sighed with emotion, looked out the window, and continued: "It took us more than ten years to complete the journey, but Chen Xing only took one year. It is indeed amazing."

Kunpeng Company was established in 1987, and Kunpeng Bantian Base was built in 1998. There is a difference of 11 years.

Although Longxing Technology was not established in 2014, it was the year Chen Xing took over, which can be calculated using the first year.

Ren Wanzhou smiled calmly and responded: "Just call me Wanzhou. I'm just here to drive the car."

Just as his right foot touched the ground, Chen Xing's highly recognizable voice came from not far away.

He took the lead and led the way.

As the vehicle drove through the base for about five minutes, Ren Wanzhou also saw the blue and white sign of the parking lot.

Because Chen Xing invited Ren Guofei, and now Ren Guofei's "biological daughter" is also here. If she is really only responsible for driving and looking after the car, she will be treated as an outsider.

What would Ren Guofei think if he treated Ren Wanzhou as an outsider?
Chen Xing, who had been working hard for many years, naturally understood that there was something behind Ren Wanzhou's words, and responded with a smile: "Well Wanzhou, Brother Ren, let's stop standing around and go to the R&D building together. This satellite base station cannot be delayed."

"This design is indeed good. It is not a single skyscraper structure, but a three-in-one structure, which can reduce the depression of internal scientific research. After all, no one likes birdcages." Ren Wanzhou also agreed.

After the two met, Ren Wanzhou also walked quickly from one side of the car door to the side of Chen Xing and others and said hello: "Mr. Chen."

The three of them continued to move forward.

The three of them stood in front of each other, with Ren Wanzhou keeping a slight distance.

Ren Guofei smiled.

"Please, both of you."

Chen Xing made an invitation gesture and said: "You two, please come with me."

Ren Guofei: "..."

The ground base stations have been bombed, and they are also thinking about building satellite base stations with global coverage. This is an opportunity for win-win cooperation.

"Let's go up."

The words fell.

But is it really just driving?
Obviously impossible.

"Then excuse me."

Ren Guofei and Ren Wanzhou responded one after another.

When they arrived at the three-story staircase of the U-shaped R&D building, Ren Guofei and Ren Wanzhou looked up to observe the core area.

"it is good."

"Haha, long wait, long wait."

"Elder Princess Kunpeng is here too?"

Chen Xing was slightly surprised.

"The three buildings are connected, and they look really grand. There is also a garden fountain, which is very pleasing to the eye."

Ren Guofei opened the car door and responded.

"I've been waiting for you for a long time, Brother Ren."

"Ren Guofei, CEO Ren, I have heard the name of Kunpeng Company for a long time. Let me introduce myself. My name is Daoyichman. I am an information and communication engineer at the United Nations, and I am also the interim chief of Longxing Technology."

I saw Chen Xing taking steps to the right and continuing to lead the way: "Because the building is a connected structure, just find an entrance and go up. You two, continue to follow me."

She skillfully drove the car into the parking lot, found the spot, stopped and turned off the engine. She looked at Ren Guofei and said, "Should I wait here?"

Ren Guofei couldn't help but admire.

After chasing ten years in one year, Ren Guofei admires him from the bottom of his heart.

Listening to the two people's praise, Chen Xing also said extremely modestly: "If I can get recognition from two people, then I know that the money is well spent."

"Let's go together."

The moment Ren Guofei walked out of the elevator, Deutschmann and the information and communication team had been waiting in the corridor for a long time.

The three of them entered the security check area, and because of Chen Xing's "face recognition", they reached the elevator area easily.

After pressing the button on the top floor, there was a sense of weightless lifting, and the elevator gradually came to a stop, and a "ding" door opening prompt sounded.

"Please lead the way."

Walking up three flights of stairs, you arrive at the entrance area of ​​the U-shaped R&D building, where you can more intuitively see the garden fountain in the middle used to divert water.

Chen Xing gave way politely.

Ren Wanzhou: "..."

Silence is Cambridge tonight, and it is also the best interpretation at this moment.

They don't know Deutschman?
This is impossible.

The construction of 4G signal base stations has become the main business of Kunpeng Company. How could they not know Deutschmann?

This old man is the founder of the fourth generation of information and communication technology. The United Nations ITU Alliance can collect a large amount of patent fees entirely because of this "top master".

The top United Nations engineer appeared here, and Ren Guofei and Ren Wanzhou looked at Chen Xing a little strangely.

They might actually be right.

Chen Xing is no ordinary person!

Can ordinary people call this old man over from the United Nations?

impossible!

Not to mention ordinary people, even the top second generation may not be able to shout because Deutschman is a bear nationality.

Being able to bring him over to help out, Chen Xing's energy was beyond the imagination of Ren Guofei and the other two, and they even began to recall how many generals there were with the surname Chen.

"Ahem." Seeing that Ren Guofei and the two were shocked, Chen Xing coughed twice and introduced them to each other: "Brother Ren, this is Professor Deutschman, this is Chief Qian Yu, these two are from the United Nations Engineers Shen Sen and Yu Bicheng…”

"I have long admired Professor Deutschmann."

"Hello, Chief Qian."

"Engineer Shen and Engineer Yu, I have heard about your deeds a long time ago. I didn't expect to see you here."

Under Chen Xing's introduction one by one, Ren Guofei, a business veteran, quickly became familiar with the engineers.

Because Ren Wanzhou was "younger", she couldn't say a word at all, so she could only nod slightly while Ren Guofei was talking.

Due to the urgent situation of the "satellite base station", Chen Xing did not want to continue to be polite and went straight to the point: "Let's move to the seminar room to discuss the feasibility of the satellite base station first."

"Row."

"No problem." "Let's go then."

Ren Guofei and others responded one after another.

The group of people walked out of the elevator corridor and arrived at the corridor of the R&D building. Chen Xing skillfully led the people to the left and opened the door labeled the seminar room above.

"Sit wherever you like."

Chen Xing greeted.

Regarding the seat selection, if you usually have to study it for a while, because it involves seniority and position.

For example, if the left is bigger than the right, the number one on the left must be the number two. If the team is at this moment, the number two can only be Deutschman, and the number three is Ren Guofei.

But no one cared about it this time. After finding a seat and sitting down, Ren Guofei took the lead and got straight to the point: "I thought about it on the way here. Satellite base stations are not impossible, but there are several difficulties that need to be solved together."

"What's the difficulty?"

Chen Xing asked.

The other engineers braced themselves.

Ren Guofei didn't sell it out and told the whole story: "The first difficulty is the cost issue. Launching a satellite requires a launch vehicle. According to the cost I know, a rocket launch costs tens of millions or even over 100 million."

"Not to mention global network coverage, in the Dragon Kingdom region alone, at least 500 satellites are needed to build a cellular network to achieve satellite network access."

"The second difficulty is technical issues. We have tested millimeter wave signals. They are easily interfered by clouds, rain, thunder and other environments. This is what we need to overcome."

"The third difficulty is the equipment problem. Satellites are ultra-precision equipment. Our Kunpeng Company has not laid out the space field, so we know nothing about it. If Brother Chen and Longxing Technology don't have the layout, I'm afraid there will be a long way to realize the satellite network." There is still a long way to go.”

"The fourth difficulty is to agree on a communication agreement. China Mobile, China Unicom and China Telecom cannot be replaced. If you want to build satellite base stations, you must reach an agreement with them."

When the four difficult points were thrown out, not only Chen Xing fell into silence, but even Deutschman couldn't help but frown and think secretly.

As Ren Guofei said, the first difficult funding issue is that even if one rocket launches two satellites, it will cost a total of 250 billion, and there is no guarantee that a single launch vehicle will be this price.

The most important thing is that 500 satellite base stations are only a rough estimate. It is not impossible to actually have 600, 700, or even 1000 satellite base stations.

If 1000 are launched, this is simply not a liquidity expenditure that Longxing Technology and Kunpeng Company can afford.

Secondly, there are technical and equipment issues. Even if there is money to launch satellites, it will be useless if these problems are not solved.

Why do we need to negotiate with the three major operators to finalize the communication agreement?

Very simple.

They are directly controlled state-owned enterprises.

The total number of employees from the three companies is in the millions.

What if Longxing Technology and Kunpeng Company privately draw up an agreement, launch new numbers, develop new operating networks to compete with them, resulting in a large number of people losing their jobs?

If this is done, the Ministry of Communications will probably stop the "satellite" project immediately.

Chen Xing and Ren Guofei just want to make money and get rid of the threat from the West, not to cause social chaos.

Of course, the most critical thing is that neither Longxing Technology nor Kunpeng Company has the grassroots background of the three major operators.

For example, grassroots customer service, grassroots engineers, grassroots service stores, etc. all need time to accumulate. It cannot be said that they are all recruited at the same time. That will only cause confusion in business operations, because the mixture of good and good will inevitably lead to cliques.

The correct approach is to recruit a few people for each position, wait for the old people to get familiar with it, and then recruit new people. The old people will train the new people, and kick out the new people who can't integrate until the new people are suitable. This is basically what companies do.

……

After listening to the difficulties raised by Ren Guofei, Chen Xing also responded patiently: "I have some connections regarding the launch vehicle issue. Now I still have to focus on solving the technology, equipment and protocol issues."

"He really has connections."

Ren Guofei was surprised.

He knew that when Chen Xing went to launch the Beidou satellite, someone must have recommended it, otherwise why would he be allowed to launch it.

That day, he not only broadcast live on the national channel, but also pressed the launch button, and even went up to speak at the end. This is impossible to do without connections.

You even have connections in the launch vehicle, but you still call yourself an ordinary entrepreneur?

Ren Wanzhou has determined that Chen Xing is the legendary top second generation.

"Mr. Chen does have this ability." Doichiman agreed. He roughly knew Chen Xing's network of contacts. After saying this, he changed the subject and said: "We will focus on solving the last three problems. alright."

After a pause, he continued: "My team and I have come up with preliminary solutions to the problem that clouds, rain, and lightning may interfere with millimeter wave signals."

"That is to integrate and alternate centimeter waves, decimeter waves and millimeter waves to switch to 4G bands on rainy days to avoid network interference. No matter how refined our network underlying algorithm is, we can achieve low latency as long as the network speed is maintained at 10MB/s daily. Everything is connected.”

“What is the initial test speed of 5G now?”

Ren Guofei asked a sensitive question.

Qian Yu glanced at Chen Xing. After the latter nodded slightly, the former immediately responded: "The initial test speed is 4MB/s."

"Almost three times faster." Ren Guofei murmured in his heart. According to development, it is only a matter of time before the 5G network breaks through 10MB/s, and the 4G network algorithm is still being updated, and the network speed is getting faster and faster, Deutschman said is entirely possible.

At this moment, Chen Xing spoke again: "As for the satellite equipment problem, I may have a solution."

Qu Cheng, Wang Qi, and Liu Dongsheng are all academicians of the Beidou project. They must know the academicians who manufacture or design satellites.

If Chen Xing asks for help, based on their past efficiency, there is a high probability that they will choose to help connect people.

"There are still people."

Ren Wanzhou wriggled her lower lip.

Her eyes looked back and forth at Chen Xing. This man was really unfathomable and he had maximized his network of connections.

Ren Guofei's pupils flashed with surprise, and he said a little uneasily: "In other words, there are solutions for the launch vehicle and technical equipment, but what is missing now is a communication protocol?"

"No!"

Chen Xing shook his head and asked: "Our biggest problem is whether the satellite base station can be realized, because the distance from the ground to low orbit is 500 kilometers."

"500 kilometers is indeed an unreachable distance on the ground." Ren Guofei responded calmly. Suddenly, he changed the topic and said: "But in the sky without any building obstruction, I think it is achievable."

Why does the signal base station have such a small coverage area?

Very simple.

There are buildings blocking the signal.

Whether it is millimeter waves, centimeter waves or decimeter waves, some of their signals will be weakened by steel and concrete.

This is why signal base station boxes can be seen everywhere in the city.

In open areas, such as grasslands or mountain villages, only one super macro base station is needed to cover a range of more than ten kilometers.

Of course, the speed of the ultra-large coverage area of ​​more than ten kilometers may not be very good because it is a super base station that pursues coverage, but basic calls are still no problem.

"can be realised?"

Hearing this, Chen Xing felt happy.

We must know that low-orbit near-Earth satellites can only accommodate up to 60,000 satellites, which are non-renewable location resources.

If the satellite base station is feasible, then it must obtain the best low-orbit position before Marsik launches the Starlink satellite.

"Theoretically, it's possible." Ren Guofei nodded and continued with a faint smile: "But whether it will work specifically, we still need to complete a comprehensive test as soon as possible."
