At the press conference on terahertz communication equipment, the whole mountain city is discussing, they have enjoyed nearly half a year of free, high-speed wifi, and the highest tower in the world in the mountain city, has never explained this phenomenon, until the terahertz equipment appeared, they know their own wisdom, why the network speed is so fast!

When the terahertz equipment is about to hold a press conference, countless reporters flock to sign up, compared with the process of the traditional press conference, Zhu Cheng's press conference is undoubtedly simpler. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

He didn't need to organize the customer service department to bombard his targets, make phone calls, text messages, visit people, and so on, and likewise, his press conference was filled with people, and the selection list became the top priority of the customer service department, not the phone call.

The list is quickly confirmed, the standard invitation letter is issued, and Shancheng TV will also broadcast the scene live as soon as possible.

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

Holographic projectors, holographic cameras, large projection screens, smart lights, and a series of other items, of course, these products are dwarfed in front of the terahertz communication that Cree is about to release.

All the confirmed lists, waiting for today's protagonist to appear, Zhu Cheng has been out of their sight for 6 months, and during this time, although he has a wise eye to sweep the world, more and more warheads are being shipped, and personal jetpacks have become a new toy for high-end people. But everyone still thinks that Cree's immersion time is too long!

As soon as the lights dimmed, the lights of the conference platform hit the corner, Zhu Cheng slowly walked to the stage, at this time, he was not a little nervous in the face of only 800 people, indescribable freehand and relaxed.

"Hello everyone, I'm Zhu Cheng."

As soon as his words fell, the whole venue erupted in 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 terahertz large energy radiation source, I believe that you uncrowned king has already done countless materials before coming to this scene, and we will still take the trouble to tell his greatness again."

"What's our newsletter like? In ancient times, we beat drums to convey sound, beacon fire and wolf smoke to transmit military information, post station stagecoach to transmit documents, flying pigeons to transmit letters, relatives and friends to carry a series of methods, such as a series of methods, to convey information. ”

"Let's take a look at modern communications, and the earliest electromagnetic wave communication is called the telegraph, the sound of the telegraph is an important tool for film and television works to set off the atmosphere of the times, and human beings have finally mastered a means of transmitting and exchanging information over long distances. This originated with the invention of the cable telegraph by Samuel Morse in 1838. The second thing we're going to see is the corded phone, which comes from Bell Labs. ”

"Bell's telephone was improved in the hands of Edison in 1876, using the composite vibration of sound to air, through the charcoal transmitter, so that the degree of sealing of charcoal essence changes, that is, the size of the resistance changes with the change of sound, so that the entire telephone circuit produces a change of current, this current that changes with the change of sound through the telephone line, in the receiver electromagnetic induction is reduced to sound vibration. This principle continues to this day. ”

"We use microwaves, one of the electromagnetic wave families, to build a relay station over the mountains. Three more synchronous satellites were launched, allowing instant communication to any corner of the planet. ”

"Today, in the 21st century, more than one million kilometers of telephone communication cables have been laid around the world! This length is equivalent to three times the distance from the Earth to the Moon! If you calculate the length of the cable core, it will exceed the distance from the earth to the sun. ”

"And today, we bring the key that opens a new door to the world of communications, terahertz. With its unique frequency, this electromagnetic wave carries an impact beyond our imagination into our world. Let's enter the era of terahertz communication together! ”

After Zhu Cheng warmed up at the beginning, he began to prepare for his continued introduction, and the atmosphere of the press conference was quite strong, and the participants 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 microwave communication, it can provide a wireless transmission rate of 10Gb/s, which is hundreds or even thousands of times faster than the current ultrafast band technology, and the beam is narrower! Better directionality! It has a stronger ability to penetrate sand and smoke smoke! This is the unique charm of the teraherz band! ”

"Nowadays, people's demand for the network is getting higher and higher, today, our backbone network, through optical fiber, dense wavelength division multiplexing and other solutions in the rapid expansion, trying to break through the bandwidth barrier of the electric router point through all-optical routing, and access network expansion, a solution is naturally optical fiber, optical fiber access technology is not a problem, but received the limitation of installation and maintenance costs!"

"Today! Cree proposes a solution to achieve network expansion! Wireless access! Low cost, wide coverage, for some remote areas compared with optical fiber, has a unique advantage, after all, infrastructure personnel over the mountains and mountains to build optical cables and build a relay station, the latter is easier to achieve. ”

"The higher the bandwidth, the higher the carrier frequency required. According to the growth rate of Moore's Law, the carriers of our current radio communications have entered the THZ spectrum. And today, Cree has come up with a feasible terahertz communication equipment, this complete set of equipment! It will be an epoch-making key in the field of communications! ”

A huge holographic projection appeared behind him, even for reporters, this highly professional product, in their eyes, is like a book from heaven, and they can't understand his content at all.

Zhu Cheng is also not interested in explaining, this equipment includes a transmitter subsystem, a receiving subsystem, a duplexer and an antenna access port, a capture, tracking and targeting subsystem, an auxiliary function subsystem, a communication subsystem, a communication link, and a complete data transmission, while the auxiliary system establishes the instructions and related parameters of the communication system through the telemetry and remote control module, and controls the working mode of the THZ communication terminal.

If this set of theories is spoken, perhaps the reporters below will fall asleep, so he decided to remove the introduction of this structure, and he decided to say something of interest.

"Today, the market share of terahertz is as high as $5.21 trillion! This number is growing rapidly at a rate of 37% per year, and I believe that Cree will occupy a large market share in it, just as Zhiyan did in the market share of holographic glasses! ”

He had so much to say, but the reporters in the audience clearly didn't want to know about it. He thinks it's better to build a terahertz special website and leave the profession to the professionals.

After sorting out my thoughts a little and preparing for the next reporter's questions, the bulk of this press conference focused on Cree's reporters.

"Mr. Zhu Cheng, where did you go in the 6 months you disappeared? Cree's blowout of high-tech has stalled in the past six months. I'm a special correspondent from Dragon TV. “

"Do you think I'm exhausted? Not really, on the contrary, I have been working on terahertz communications for the past six months, and this means a lot for our future! ”

Zhu Cheng had already prepared this answer.

"Mr. Zhu Cheng, I am a reporter from Reuters, may I ask Mr., you have invested a lot of money in biology, and added a biological industry chain in the industrial circle of Cree, and then announced the joint establishment of a research institute with the AVIC Academy, and yesterday used a high-energy terahertz radiation source to reach a cooperation with hundreds of laboratories and research institutes for talent exchange and professional training.

A brown-haired reporter raised his hand to ask, this question had already been raised by Zhang Youlin, and was asked by Zhao Ling. Zhu Cheng didn't answer, and this question is also the wonder of countless people who pay attention to Cree, what does Cree want to do! Or what does Zhu Cheng want to do!

Zhu Cheng sorted out his thoughts and prepared to answer positively, he had already prepared the manuscript, even if the reporter didn't ask questions, he would ask it!

"If we walk around the 17th century, we will find that it was an era of theocracy, church rule, when the power of the church was still hindering the development of natural science, Kepler, the sky lawgiver, and Galileo, the founder of modern mechanics, were in that dark age. Wantonly exude their own light! As a result, Italy became the world's scientific center. ”

Behind Zhu Cheng also appeared a holographic projection of Galileo, the quill in his hand taking notes on the parchment roll, and the microscope in his hand that could "make a fly as big as a hen" rotate beside him.

In 1633, Galileo, who was nearly seventy years old and sickly, was forced to go to Rome in the cold winter season, where he was interrogated three times under the threat of torture. After several tortures, on June 22, 1633, in the halls of the Convent of Santa Maria, a joint co-sentence of 10 cardinals was pronounced for violating the 1616 prohibitions and doctrines. ”

This hall also appeared behind Zhu Cheng, highly restoring that trial.

The books held high, the holy water sprinkled, the pronounced sentences of arias, the robes of hunting, the pathos of Galileo's figure, kneeling on the cold stone slab with difficulty, signing the "letter of repentance" written by the Holy See, appeared vividly in front of everyone.

In 1637, he lost his sight. In 1639, he took in his last student, Viviani, and until his death in January 1942, he was still engaged in scientific research, discussing with several students and friends about the design of mechanical clocks, collision theory, the balance movement of the moon, the height of the water column in the mine at atmospheric pressure, etc., and finally closed his eyes on the 8th. Hurriedly buried. (To be continued.) )
