Chapter 890 Broadcasting

Dayang Group, Zhang Hao announced the end of the meeting.

"Everyone, there is nothing to make a fuss about. The Xuanhuang World's attack is expected. It would be strange if they didn't respond.

The Ming Dynasty can almost let it go.

Next, we will develop according to the plan.

We must make full use of our technological advantages, win over one group and suppress another group, and seize the market tightly. "

For possible developments, Dayang Group has long planned. Dayang Group now has its own think tank, and Dayang Group itself is the source of all kinds of storms around the world. It is almost possible to predict how the world will react.

After leaving the conference room, Zhang Hao came to the research base. In the current research base, there are many important technologies that are on the verge of breakthrough.

The third generation of computer technology is being studied intensively. The third-generation technology is an integrated technology, and it is also a key stage for computers to enter maturity.

Computer technology at this stage began to advance by leaps and bounds. The highly integrated technology also puts forward higher requirements on the overall technical situation of Dayang Group. And the technology at this stage will completely widen the gap between the rest of the parties and Dayang Group.

In addition, research on various arrays, machine tools, war machines, cultivation, life and medicine, etc., needless to say.

Zhang Hao visited some research institutions, and finally went straight to the communication research base.

At present, Dayang Group has set up a special communication research base, and the current important public relations research is the realization of global communication.

It is still difficult to launch satellites temporarily, so we can only find other ways to solve it. And Zhang Hao's approach is to form a research group and brainstorm.

The leader of this research team is Li Yu. Li Yu used to be Zhang Hao's secretary, and later entered the scientific research department because of his solid professionalism. Later, because of his outstanding ability, he was finally entrusted with the important task of being in charge of the research of global communication networks.

This is a typical up and down, which laid the political foundation for Li Yu. But his solid scientific literacy cannot be ignored. Only with professional knowledge, a better understanding of politics, and the fundamental interests of the Dayang Group, has he gained his current status.

Zhang Hao came here today because Li Yu proposed a brand new solution.

Here at the research base, there is already a model, an extremely exaggerated model of a hot air balloon that Zhang Hao has never seen before—very slender.

Li Yu explained next to him: "Teacher, previous research has shown that the higher the signal source is from the ground, the farther it will propagate. In the final analysis, it is because the earth is spherical.

The best way, of course, is to launch satellites. But satellite technology is still under study. After thinking about it, we thought of a hydrogen balloon.

What if we could use a hydrogen balloon to hang a small signaling device thousands of miles into the sky?

According to the research of astronomers such as Zhao Dahe, the thickness of our atmosphere is about 1260 kilometers based on the density of one-thousandth of the ground.

The reason for taking one-thousandth is because we have calculated and tested that the hydrogen balloon can fly to this height. Of course, what we tested was no-load. It is no problem to actually fly to 1200 kilometers.

According to calculations, if the radio signal device can be transmitted to an altitude of 1,200 kilometers, then the signal can cover a range of about 24,000 kilometers in diameter.

From our place to Xuanhuang World, only ten hydrogen balloons can complete the link of the wireless communication network.

Before the satellite can be successfully launched, we can rely on this method to establish a global communication network. "

Zhang Hao thought: "Launch a hydrogen balloon to a high altitude. If I remember correctly, as the altitude increases and the air pressure decreases, the hydrogen balloon will continue to expand. In the end, the hydrogen balloon will burst itself.

Only a few materials such as silk can withstand such a force. But the cost is too high.

Moreover, the expansion of the hydrogen balloon will cause air leakage problems. Also, if you are suspended in the sky, you will be exposed to the scorching sun, and the time may not last long. "

"This is also one of the difficulties of previous research. Now this problem has been solved. We got a kind of chemical fiber at the chemical research base. With the hydrogen balloon made of this chemical fiber, we can control the cost of each hydrogen balloon at Within a top-grade spirit stone.

In addition, this chemical fiber has a lifespan of one year even if it is completely exposed to the sun. If hydrogen balloons are manufactured and coated, etc., the hydrogen balloons can have a service life of three to five years. "

Zhang Hao asked again: "If it is high altitude, the intensity of sunlight should be several times that of the ground?"

"Because of the thick atmosphere, the intensity of sunlight at high altitudes is almost 12 times that of the ground. But we have already calculated this factor."

"Then there is another problem. The hydrogen balloon is launched to such a high position, can't it be controlled from the ground?"

Li Yu was a little proud, "Teacher, there is no need to control it at all. Because the high-altitude air circulation is relatively weak and stable. We plan to launch 500 hydrogen balloons high into the sky.

According to spherical calculations, theoretically 145 hydrogen balloons are enough. But considering the actual situation, about five hundred.

These hydrogen balloons are thrown directly into the sky at an altitude of 1,200 kilometers, and they can just float casually. As long as we release it here at Dayang Group, the balloon can float all over the world. Of course, in order to arrange as soon as possible and evenly, we will use fighter jets or air and space aircraft carriers to release.

At such a high altitude, the hot air balloon is temporarily safe. At least three years should be enough.

There is also the cost. Based on comprehensive calculations, the annual cost of this communication method of launching hydrogen balloons can be controlled within 10,000 commodity spirit stones.

In the past, in the construction of ground base stations, the annual maintenance cost of a base station was at least ten high-grade spirit stones. Dayang Group's annual maintenance costs for the base station were as high as one million.

And I believe that within three years, we will be able to successfully launch satellites. "

Zhang Hao didn't nod immediately, but thought again for a while before saying: "Is it possible to recover this kind of hydrogen balloon? If it is really all floating at high altitude, it will definitely affect the launch of satellites in the future."

"Teacher, we all have designs. Hydrogen balloons have individual and unified passwords. We can detonate the balloons remotely, individually or collectively.

The signal transfer devices carried by the balloon are all universal, and there is no fear of the hydrogen balloon accidentally falling or being picked up by others. "

"The signal device needs energy. How to solve the energy?"

"Five low-grade spirit stones are enough for five years. This can also reduce the weight of the signal device to the limit."

Zhang Hao nodded in satisfaction after hearing this. "Very good, if you are sure there are no problems, let's start implementing. If 500 hydrogen balloons are not enough, then 1,000. But it is necessary to build a global communication network as soon as possible.

Next, we have big moves. "

"yes!"

In the next few days, the whole world became more and more lively. Under the instigation of Xuanhuang World and Lingbo Group, all parties began to consciously establish geographical barriers, trying to block Dayang Group and Dayang Group's allies in terms of information exchange and morality.

We used newspapers as a platform to wage an unprecedented war.

In particular, many forces make full use of the delay problem of information to get involved.

At this time, it was a typical case of "defending the people's mouth is better than Fangchuan", and Dayang Group seemed to have no power to parry for a while.

At the same time, the Ming Dynasty and the Xiaoyao faction, etc., have gradually stepped out of the influence and sanctions of the Dayang Group because of the support of Xuanhuang World.

The time quietly came to late May.

This morning, Wang Ruiyang was planning the next offensive to formally influence Dayang Group's "World Standard Seminar", but the secretary ran in with a newspaper:

"Mr. Wang, yesterday's newspaper has arrived. Dayang Group uses red headlines again."

Wang Ruiyang immediately sat up straight, took the newspaper and read it. But on the first edition, it was written in red title:

[Let the world have no borders, 'broadcasting' changes life]

Subtitle: Another breakthrough in radio technology, Dayang Group will establish a global communication network, Dayang Group will establish a radio station, and the first batch of radios will go offline.

"Broadcasting? Radio? Radio station? Global communications?" Wang Ruiyang frowned deeply as he looked at these unfamiliar words. Although I don't know much about it, I always feel that...it's not simple.

Looking at the content below, Wang Ruiyang couldn't sit still anymore.

According to the content published above, Dayang Group has completed the distribution of radios. Dayang Group will officially start selling radios tomorrow morning at 8 o'clock local time of Dayang Group; sales points around the world will sell at the same time—whether it is late at night or not.

The farthest point of sale of Dayang Group has appeared in Hetu World. Although there are only a few pitiful sales points. But in Xuanhuang World, there are already hundreds of sales points including large and small, direct sales and agents.

The newspaper also publishes the distribution volume of each point of sale. At least 30,000 radios were prepared at each point of sale.

There are three models of the radio, which are popular version, deluxe version and exclusive version. The prices are: 199 yuan, 1999 yuan and 19999 yuan. The deluxe version is 1% of the total amount, and the premium version is 10-30 units per sales point.

Among them, the exclusive version is not only a radio, but also has the function of a telegraph - it can send messages, and it is a voice call.

But if you want to buy it, you can only use Dayang Group banknotes, and traditional currency transactions such as spirit stones are not accepted on site. The denomination value of Dayang Group's banknotes is: a low-grade spirit stone = 100 yuan, which can be exchanged at the bank branches of Dayang Group.

Of course, you can also go to some commercial banks to wait for transactions-but the specific transaction price, Dayang Group doesn't care, because the only formal transaction recognized by Dayang Group is Green Boat Bank.

"Radio!" Wang Ruiyang pinched the newspaper, but he didn't realize that the newspaper had been twisted into a ball. The newspaper also gave the frequency of Dayang Group's radio station. Including News Channel, Academic Channel, Practice Channel, Commercial Channel, Mercenary Channel, a total of five major channels.

Wang Ruiyang took a deep breath and said to his secretary Wang Ye: "Go to the sales point of Dayang Group to buy a few radios. Also, pay attention to collecting the sales information on the spot. Also send people to the sales points of Xuanhuang World to observe."

"Yes." Wang Ye responded and left immediately.

When Wang Ye left, Wang Ruiyang looked down at the newspaper. For some reason, he trembled slightly.
