Chapter 140 World Science Center
Regarding the press conference of terahertz communication equipment, the whole mountain city is discussing that they have enjoyed free, high-speed WIFI for nearly half a year, and the tallest tower in the world in the mountain city has never explained this phenomenon until the terahertz When the device appeared, they realized their own wisdom eyes, why the Internet speed is so fast!

When the terahertz equipment was about to hold a press conference, countless reporters flocked to sign up. Compared with the traditional press conference process, Zhu Cheng's press conference was undoubtedly simpler.

He doesn't need to organize the customer service department to bombard his targets indiscriminately, and invite them by phone calls, text messages, door visits, etc. Similarly, there are an endless stream of people signing up for his press conference, and the screening list has become an important part of the customer service department. Medium-heavy work, not phone calls.

The list was quickly confirmed, the standard invitation letter was sent out, and Shancheng TV Station will also broadcast the scene live at the first time.

The venue for the press conference is the conference room on the first floor of the Gemini Tower, a large conference room with a floor height of 4 meters and 800 seats.And this meeting room is a collection of all the high-tech products of Cree.

A series of items such as holographic projectors, holographic cameras, large projection screens, smart lights, etc. Of course, these products pale in comparison to Cree's upcoming terahertz communication.

All the confirmed lists are waiting for today's protagonist to appear. Zhu Cheng has been out of their sight for 6 months. Many, personal jet backpacks have become a new toy for high-end people.But everyone still thinks that Kerui has been immersed in it for too long!
When the lights dimmed, the lights of the conference table shone in the corner, and Zhu Cheng walked slowly onto the stage. At this time, facing only 800 people, he was not a little nervous, and he was indescribably freehand and relaxed.

"Hi everyone, I'm Zhu Cheng."

As soon as his words fell, the whole venue burst into warm applause!This is to celebrate the return of their former king of black technology!
"The product we are going to release today is called a terahertz high-energy radiation source. I believe that the uncrowned kings have already done countless materials before they came to this scene. At that time, we will still take the trouble to tell his greatness again."

"What is our communication like? In ancient times, we used a series of methods to convey information, such as beating drums to transmit sound, beacon fire and beacon to convey military information, post station and posthorse to convey documents, flying pigeons to convey messages, and relatives and friends to convey information."

"Let's take a look at modern communication. The earliest electromagnetic wave communication was called the telegraph. The beeping of the telegraph is an important tool for film and television works to set off the atmosphere of the times. Humans have finally mastered a means of long-distance transmission and exchange of information. This has its origins in the wired telegraph invented by Samuel Morse in 1838. The second we're going to look at is the wired telephone, which originated at Bell Laboratories."

"Bell's telephone was improved in Edison's hands in 1876, using the compound vibration of sound to the air, through the carbon microphone, to change the degree of closeness of the carbon, that is, the size of the resistance changes with the change of the sound, so that A changing current is generated in the entire telephone circuit, and this current that changes with the sound passes through the telephone line, and generates electromagnetic induction in the receiver to restore the sound vibration. This principle continues to this day."

"We use microwaves, one of the electromagnetic wave families, to build relay stations across mountains and mountains. We have launched three more synchronous satellites, enabling instant communication in any corner of the earth."

"Today in the 21st century, more than one million kilometers of telephone and communication cables have been laid all over the world! This length is equivalent to three times the distance from the earth to the moon! If the length of the cable core is calculated, it will exceed the distance from the earth to the sun."

"Today, we bring the key to open a new door to the world of communication, terahertz. With its unique frequency, this electromagnetic wave enters our world with a shock beyond our imagination. Let us enter terahertz together Communication age!"

After Zhu Cheng warmed up the opening, he began to prepare for his continued introduction, and the atmosphere of the press conference was quite strong, and the participants all knew a little bit about the basic information of terahertz.

"Because the unique frequency band of terahertz is 1 to 4 orders of magnitude higher than that of microwave communication, it can provide a wireless transmission rate of 10GB/s, which is hundreds or even thousands of times faster than the current ultra-fast band technology, and the beam is narrower! Direction Better performance! It has a stronger ability to penetrate sand, dust and smoke! This is the unique charm of the terahertz frequency band!"

"Nowadays, people's demand for the network is getting higher and higher. Today, our backbone network is rapidly expanding through optical fiber, dense wavelength division multiplexing and other solutions, trying to break through the bandwidth barrier of the electrical router through all-optical routing. For access network expansion, one solution is naturally fiber optics, the technology of fiber optic access is not a problem, but it is limited by the cost of installation and maintenance!"

"Today! Cree proposed a new solution to achieve network expansion! Wireless access! Low cost and wide coverage. Compared with optical fiber in some remote areas, it has unique advantages. After all, infrastructure personnel have traveled across mountains and mountains to build optical cables and The latter is easier to achieve than building a relay station."

"The larger the bandwidth, the higher the required carrier frequency. According to the growth rate of Moore's Law, the carrier wave of our current radio communication has entered the range of THz spectrum. Today, Cree has come up with practical terahertz communication equipment , This complete set of equipment! It will be an epoch-making key in the field of communication!"

A huge holographic projection appeared behind him. Even reporters, this highly professional product, in their eyes, are like a bible, and they can't understand his content at all.

Zhu Cheng is also not interested in explaining that this equipment includes a transmitting subsystem, a receiving subsystem, a duplexer and an antenna access port, an acquisition, tracking and targeting subsystem, and an auxiliary function subsystem. It starts the communication subsystem and establishes a communication subsystem. The link completes the data transmission, and the auxiliary system establishes the commands and related parameters of the communication system through the telemetry and remote control module to control the working mode of the THZ communication terminal.

If this set of theories is explained, the reporters below may fall asleep, so he still decided to remove the introduction of this structure, and he decided to say something interesting.

"Today's terahertz market share is as high as 5.21 trillion US dollars! This number is growing rapidly at a rate of 37% per year. I believe that Cree will occupy a large market share in it, just like the wisdom eye in the holographic glasses market. The share is the same!"

He had too many things he wanted to tell, but the reporters in the audience obviously didn't want to know about them.He thinks it is better to build a terahertz special website and leave the professionalism to professionals.

After sorting out my thoughts a little bit, I was ready to answer the next reporter's questions. The big head of this kind of press conference was concentrated on Kerui's reporters.

"Mr. Zhu Cheng, where did you go during the six months you disappeared? Cree's blowout high-tech has stagnated during these six months. I am a special reporter from Dragon TV."

"Do you think I'm exhausted? That's not the case. On the contrary, I have been researching terahertz communication for the past six months, which is of great significance to our future!"

Zhu Cheng had already prepared this answer.

"Mr. Zhu Cheng, I am a reporter from Reuters. Excuse me, sir, you have invested a large amount of money in biology, and added the industry chain of biology to Cree's industry circle. The joint establishment of a research institute, and the use of high-energy terahertz radiation sources yesterday reached a cooperation in talent exchange and professional training with hundreds of laboratories and research institutes. May I ask you, sir, what are you doing for so many steps?"

A brown-haired reporter raised his hand to ask a question. This question had already been asked by Zhang Youlin, and then asked by Zhao Ling.Zhu Cheng did not answer, and this question is also the doubt of countless people who follow Career, what is Career trying to do!Or what exactly Zhu Cheng wants to do!
Zhu Cheng sorted out his thoughts and prepared to answer directly. He had already prepared the draft. Even if the reporter didn't ask any questions, he would raise them!
"If we walk before the 17th century, we will find that it was an era of theocracy and church rule. At that time, the power of the church still hindered the development of natural science. Kepler, the legislator of the sky, and Galileo, the founder of modern mechanics It was in that dark age. It radiated its own light wantonly! Therefore, Italy has become the center of science in the world."

A holographic projection of Galileo also appeared behind Zhu Cheng. The quill pen in his hand was taking notes on the parchment, and the microscope in his hand that could "make a fly as big as a hen" was spinning around him.

"In 1633, Galileo, who was nearly seventy years old and frail and sickly, was forced to go to Rome in the cold winter. In the hall of the nunnery, ten cardinals jointly pronounced the sentence, the main charge was violation of the prohibition and teachings of 1633."

This hall also appeared behind Zhu Cheng, restoring the trial to a high degree.

The books held high, the holy water swayed, the sound of the aria's sentence, the hunting robes, the sadness of Galileo's figure, kneeling on the cold slate with difficulty, and signing the "Repentance Letter" written by the Holy See, appeared vividly in the in front of everyone.

"In 1637, he was blind. In 1639, the last student, Viviani, was accepted. Until his death in January 1942, he was still engaged in scientific research, discussing the design of mechanical clocks with several students and friends. , collision theory, the libration of the moon, the height of the mine water column under atmospheric pressure, etc., finally closed my eyes on the 1th. Buried hastily.”

　A research paper and plan on terahertz has been uploaded to the group file, and those who are interested can take a look.I want to say too much.It doesn't appear in the chapter.Group number: Readers in the library 133708894. Group V needs to be verified.
