Wang Xueba System

Beautiful country, inside the White House President's Office.

"Did Xia Guo agree?" Bai Deng looked at Frigg in front of him.

After letting Frieg communicate with Xia Guo about this matter, Bai Deng asked him to report this matter directly to himself to ensure that he could keep abreast of the situation.

"Not yet. Xia Guo is still sending emails to negotiate this matter. They want us to fulfill the agreement according to the previous quotation, and at least increase the price a little less." Frigg replied, "For letting us Regarding the matter of Luo Hao coming to the beautiful country to participate in the technical seminar, Xia Guo did not let go, and his current attitude is very firm."

"Since they won't let Luo Hao come over, let's send someone there." Bai Deng thought for a while and said, "At present, we will continue to follow the plan we made before, until Xia Guo made it clear that he would rather not use the 5G network and stick to it." If you don't accept the two conditions, you should communicate with them, saying that we will send some mathematicians to visit and exchange, and hope that Luo Hao will be there at that time. The price is calculated, but it can also reduce the price for them.”

Frigg was taken aback, obviously not understanding what Bai Deng wanted to do, but he quickly replied: "Okay, I understand!"

Therefore, in fact, in many cases, the leader does not want his subordinates to understand all his plans, as long as the subordinates can understand what they want him to do.

After Frigg walked out of the office, the secretary asked in a low voice: "Mr. President, in this case, isn't our risk too high?"

"It's okay. Our beautiful country is the most powerful country in the world. Xia Guo has always claimed to be a country that emphasizes the rule of law and reason. They will not do anything excessive without evidence." Bai Deng waved his hand, "But To be on the safe side, let Hades choose some people to go this time, explain the matter clearly to him, he decides who to let go."

"Okay." The secretary agreed and left the office.

For a while, the somewhat empty office suddenly fell silent.

............

The capital of Xia Kingdom.

Early the next morning, Zhai Weiguo came to the office as usual and checked his mailbox.

"It's really not talking about the price at all." Zhai Weiguo looked at the content of the email and sighed.

In desperation, Zhai Weiguo had no choice but to ask Mr. Zhou for confirmation.

"Mr. Zhou, then let's not do this project?"

In Mr. Zhou's office, Zhai Weiguo looked at Mr. Zhou with a troubled expression on his face. It is difficult to do this project now.

If you do it, you will spend too much money. If you don’t do it, it will affect the development. In addition, their science and technology department is still waiting for these devices to arrive to see if they can crack the technology of the beautiful country. This is hopeless.

"Then don't do it. I have discussed this matter with several other veterans before." Elder Zhou said, "If we don't use 5g technology, we may be affected in a short time, but if Luo Hao is really allowed to After leaving the beautiful country, if there is any accident, what we lose may not be the development of the past two years!"

"Then I'll go back and reject them?" Zhai Weiguo confirmed.

"Go ahead and inform the experts of the project team to study our own 5g communication technology as soon as possible." Zhou Lao nodded, but his face was obviously a little heavy. Obviously, this matter made Zhou Lao in a bad mood.

Zhai Weiguo returned to his office, wrote an email, clearly rejected Frigg's request, and made it clear that if the beautiful country did not change the conditions, Xia Guo would stop this negotiation, stop the transaction, and at the same time recall Experts who are still waiting for technical training in the beautiful country.

After sending the email, Zhai Weiguo leaned back on his office chair and sighed, a little bit downhearted.

Xia Guo currently uses a lot of foreign technology licenses, and the money spent on them every year is not a small amount, and it is not uncommon for the other party to increase the price before, but it is the first time that it has increased so much.

"As long as one day there is still a situation of using other countries' technology, this kind of thing that gets stuck in the neck may happen at any time." Zhai Weiguo feels a little uncomfortable. How good it would be if Xia Kingdom had not been in war decades ago !

Unfortunately not if!

"I can only hope that the country has not misjudged you!" Luo Hao's figure seemed to appear in front of Zhai Weiguo's eyes.

Fuxing College Library.

Huang Xi had class today, and Luo Hao was reading in the reading room by himself.

"Hey, this communication technology doesn't seem to be that difficult." Luo Hao looked at the book in front of him and thought to himself, "As long as the signal can be converted into electromagnetic waves or light waves and sent out, and converted back to the corresponding receiving equipment, it will be fine. It is somewhat similar to the combination of the signal simulator and the signal capturer that I made before."

"The only thing you need to pay attention to is how to increase your signal transmission speed. This is also the biggest feature of the 5G communication technology promoted by the beautiful country." Luo Hao thought, "And while achieving speed, we should also ensure the stability of the signal sex and confidentiality."

"Signals are transmitted by waves, so the rate of signal transmission depends on how many waves are transmitted per unit time. That is to say, if the wavelength is smaller, the number of complete waves that can be transmitted per unit time is more. It’s just delivering more content.”

"According to the relationship between wavelength and frequency, the two are inversely proportional, and the wave velocity is determined by the medium. Therefore, when the wave velocity remains constant, if you want to reduce the wavelength, you can only increase the frequency."

The more Luo Hao thought about it, the brighter his eyes became, as if he had thought of some good method, but soon, Luo Hao frowned. It is impossible for others to fail to figure out such a simple truth, so it can only explain one thing, The higher the frequency, the easier it is for information dissemination to go wrong.

Soon, Luo Hao remembered something.

In the process of wave transmission, attenuation will occur. Diffraction, occlusion, atmospheric absorption, etc. are related to frequency. The higher the frequency, the easier it is to be occluded and absorbed.Therefore, high-frequency signals are easily attenuated.

Electromagnetic waves suffer loss when penetrating any medium.Mobile phones, wireless remote controls, wireless routers, Bluetooth, Internet of Things and other wireless devices using spread spectrum and other broadband modulation techniques will generate out-of-band emissions and spurious emissions in a wide frequency range other than the carrier frequency. cause interference to other radio equipment.

Therefore, if you want to increase the signal transmission rate, you must solve this problem, and you cannot not guarantee the quality in order to increase the speed.

"The direction is confirmed!"
