"Space-based transmission is a complementary ...... as land-based"

Vice President Han Jun introduced the strategic layout planning of the State Grid in detail for Ye Hua, the layout of unlimited transmission technology is related to the national economy and people's livelihood, and it is a hidden trump card in the international competition, and Ye Hua and the coastline group are indispensable, to a certain extent, more important than the State Grid.

The space-based system fully demonstrates the essential difference between Huaxia and the West, especially in remote areas, especially in the sparsely populated places in the northwest, and the wireless transmission base station is not in the strategic layout of the light of life.

This is not to say that Ye Hua is a black-hearted capitalist who is profit-seeking by nature, but he can't afford to lose.

In more than 700 cities across the country, Life Light's strategic plan is to build about 1,000 wireless transmission base stations to meet the needs of all cities, and the investment here alone will cost 6.75 trillion RMB.

This project is jointly promoted by Life Ray and the State Grid, and Life Ray will bear 35% of the investment, that is to say, in the 30-year plan, the Coastline Group will smash 2,362.5 billion yuan into this project, and the rest of the State Grid will pay for it, and the State Grid will not have so much money to sell itself, and it will have to rely on the national financial allocation, and the Life Light will also need a 5% subsidy.

Even so, remote areas still can't be covered, and if the whole country is covered according to the ideal, it means that 25,000 base stations will have to be built, and even if a radio tower gives it an average of 6 billion, it will need 15 trillion yuan.

This, this, this......

Not to mention the two super enterprises, even if the country's annual GDP is smashed into it, it can't fill this hole, and last year's annual GDP of China was only 128.8 trillion.

However, the state also has a hard target, even if it is wireless transmission, it must meet the requirements of electrification in every village, just like the network in every village, the road in every village, and the postal service in every village.

Like a postal service.

Private enterprise SF Express will not send some places, the reason is very simple, send an express mail to lose one, as a private enterprise must not come like this, otherwise sooner or later it will go bankrupt, not to mention that SF Express is now a listed company.

However, the national postal service must go to the countryside, and there are delivery points no matter how far away, but it takes a long time.

Similarly, as long as there is a village, it is necessary to have infrastructure such as electricity, information, roads, and networks, regardless of whether it is good or not.

Sometimes the signal in the countryside is faster than in the city, because the city uses a large network, and the opposite is true in the countryside, but the base station is erected there, and the number of people who use the network is less, it must be a loss of money, and this kind of loss-making business can only be carried out by state-owned enterprises.

The sky-high price of a tower is billions, like the remote northwest region, it is impossible to build a power tower in the past, even if it is only 35% of the investment ratio, including 5% of the subsidy, it is also ten coastline groups can not afford to lose.

However, it is also a hard indicator of the state that villages can use radio, even if a household in the countryside still uses power cords, but the electricity sent to this village must be sent in the form of wireless transmission, through a village or a township shared small and micro substation, so that the electric energy can be transmitted to thousands of households through the existing cables in the village.

After all, wireless power transmission is the trend.

The biggest difference between China and the West is that there is no signal in many remote towns and villages in the United States so far.

But on the Huaxia side, this kind of thing will not happen.

It is impossible to build land-based radio towers in both remote areas and sparsely populated areas, so the only way to get rid of the effects of the earth's curvature is to build space-based systems in outer space.

Although the transmission of terahertz coupled resonance technology is similar to the quantum tunneling effect, the thickness of several kilometers or even a few kilometers can be ignored, but the radius of the earth alone is thousands of kilometers, and the east-west-north-south span of China's territory is very large, and the tunneling effect is equal to nothing, which will be reflected in the terahertz wave received by the terminal and its weakness, or it will not be received at all.

With space-based systems in outer space, it's different, and the constraints of the Earth's curvature disappear.

Establish an access agreement with the satellite in space through the radio tower on the ground, convert the electrical energy into terahertz waves through the ground tower, and after the satellite above receives it, it establishes another access agreement towards a terminal on the ground, and then hits, the terminal receives the terahertz wave and converts it into electric energy.

The working principle of space-based satellite system and radio tower is actually the same, or the same as communication satellite, the difference is that the tower is on the ground, the satellite is in space, the tower has a high energy level, large volume and large load, and the space-based energy transmission system in space has a low energy level, small volume and small load.

The reason for the power tower is to transmit electricity to those megacities and industrial cluster centers with a population of millions or even tens of millions at every turn, and it is natural that there is a high demand.

But satellites are used to supply wireless power to sparsely populated areas in remote areas, and they certainly can't be compared to big cities.

It can be seen that under the organic combination of space-based and land-based wireless transmission systems, it can cover the whole country, including remote mountainous areas.

Han Jun introduced the specific matters of the project to Ye Hua in detail, and more than 20 minutes had passed unconsciously.

After taking a sip of water, Han Jun continued: "For the construction of the space-based transmission system, we invited the original team of the Beidou engineering team to escort us, and building this transmission system is actually the same as building a global satellite positioning system, and this task is no more suitable than the original team of the Beidou project." ”

Ye Hua thought for a moment and said, "Leave the space-based project to the life ray to operate, I mean all." ”

Han Jun nodded slowly: "It's more appropriate for you to do this than the country, you know what I mean." ”

Ye Hua smiled: "Of course." ”

Obviously, the people of the Beidou engineering team are invited to do it, this space-based system is to be networked on a global scale, and when it comes to opening up the international market in this regard, it is relatively easier for the coastline group, and the national team will make the West sensitive and make excuses.

Although even the coastline operation will still be targeted, it is relatively more suitable for the coastline.

The investment in space-based systems, even if it covers the whole world, only needs an investment scale of 100 billion RMB, of course, this is also a sky-high investment, but for the coastline group, this money can be obtained.

Ye Hua thought for a moment and couldn't help but say: "The networking of space-based systems must be as soon as possible, the sooner the better, now there are not many good orbit resources, we have to seize all his orbital resources before the European Galileo satellite positioning system, but can our domestic launch resources meet the needs of completing the global network before 2025?" ”

"In 2025? So fast? Han Jun was stunned.

"Quick? I'm still slow, but you can't expect the Europeans to stop, especially after the announcement of this project, they are in a hurry, and they have to get the satellite up before they do, and the orbit resources are on a first-come, first-served basis. Ye Hua said.

Han Jun shook his head and denied: "2025 is definitely impossible, even if it kills two satellites with one stone, it will have to be launched more than a dozen times, and 30 satellites will be launched within three years, and the launch resources will not be enough at all." But aren't you on good terms with Elon Musk? Then ask his SpaceX company for help, give him a list, insert a queue, he won't give you a limit and won't cooperate with his Tesla, haha. ”

Everyone couldn't help but laugh when they heard it.

At present, there are mainly communication satellite systems and positioning satellite systems in space, and there are four major global positioning satellite systems, such as the GPS of the United States, the Beidou of China, the GLONASSS of Russia that cannot survive and merge into Beidou, and the Galileo system, which is currently only launched by ESA.

In the near future, there will be another unique satellite system, that is, the wireless power satellite transmission system, the global network also needs 30 non-geostationary orbit satellites, the same point is the global networking, the difference is that some satellites are communication functions, positioning functions, and this set of space-based system satellite functions are wireless transmission functions.

"Okay, this favor Musk won't help me, then I won't play with him in the future, but he shouldn't have a reason to refuse, Bezos's Blue Origin company has formed more and more competitive pressure on SpaceX's launch business in recent years, and he doesn't accept this big order with a profit of at least $1 billion, Blue Origin can't wait. It's just that I'm wondering if ESA will be angry and scold my mother if it gets the news. Ye Hua said this very unkindly, causing the audience to laugh.

"Orbital resources are on a first-come, first-served basis, this is the rule set by the West, no wonder anyone, haha."

If ESA knew, it would be more than angry scolding......

It's crazy.

The satellite orbit resources planned more than ten years ago are now all occupied by the Beidou system, the European debt crisis has broken out, and European technology is available, but there is really no money to engage in these super expensive "big toys".

Speaking of which, if it weren't for the Europeans who wanted to trap people back then, it would be impossible for Huaxia to make up their minds to engage in Beidou by themselves, time has passed, it is simply the standard template for the protagonist's face-slapping plot, first looked down on it, and then decided to do it himself, and finally succeeded in slapping his face, papapa!

And the helpless ESA can only accept this fact, and has to reformulate new orbital resources for the Galileo system, but it is certainly not as good as the previous one.

This time, the Europeans felt that they could do it slowly, and the Chinese had already succeeded in their own positioning system, and he was not worried about the remaining India and Ben.

Okay, halfway through the way, a wireless transmission space-based system was launched, and the Chinese were targeting, and 30 satellites were needed, and the orbital resources that had just been planned were going to be robbed?

Ye Hua was unkindly worried that the ESA would explode if he knew about it, and was ready to break the jar, and this Galileo system of Rausch would simply be killed.

If the Galileo system wants to be built according to ESA's expectations, it will take 13.5 billion euros, or 100 billion soft girls.

Now the Europeans want to spend an additional 100 billion yuan to build a positioning system within three years, and even if they sell the EU headquarters building, it will never be possible to make up this money.

Europeans are still making yellow vests.

No money!

It's such a realistic and heart-wrenching question.

So it's so important to have money.
