Chapter 1060 Difficulties
"From the information I can find, Zijingshan Laboratory has indeed created the world's highest real-time transmission record of terahertz wireless communication in an ideal real-world environment.
Terahertz wireless communication is recognized as the core component of the 6G mobile communication system, and Zijingshan Laboratory has created a real-time transmission architecture that integrates photon, terahertz and optical fiber, achieving a single-wavelength net rate of 103.125Gbps and a dual-wavelength net rate of 206.25Gbps. The communication rate is 10 to 20 times higher than that of 5G.
What is the current level of our laboratory? I think we need to know the data in this regard. After all, it is not so intuitive to read the explanation on the equipment."
The old man who resigned from Xia Keyuan is obviously a person who pays attention to practical work and basics.
Although in the scientific research environment of Jiuzhou Technology, the phenomenon of seniority has long been smashed by Gu Qing, no matter how some people present break the secular world, they cannot change the fact that they were once students of this old man.
So this brainstorming meeting had an obvious pause at this time.
Everyone turned their eyes to Ying Shu, Li Cun and others, the heads of the 6G communication engineering department.
After receiving these gazes, Ying Shu and others felt their shoulders sink.
Although they were all people following Gu Qing, the light in their eyes was extremely dazzling when they entered the professional field.
On the big screen at the conference room, the relevant knowledge of terahertz and terahertz wireless communication was also introduced very intelligently, providing a knowledge base for some participants who did not know the details.
Terahertz (THz) is one of the frequency units, which represents the oscillation frequency of electromagnetic waves. T is a unit of quantity, 1THz= 1012Hz, so terahertz generally refers to electromagnetic waves with a frequency range of 0.1~10 THz (wavelength of 30μm-3mm), which overlaps with millimeter waves in the long wave band and infrared light in the short wave band. It is not only a transition zone from macroscopic classical theory to microscopic quantum theory, but also a transition zone from electronics to photonics.
The amazing thing is that the band of terahertz waves can cover the characteristic spectra of semiconductors, plasmas, organisms and biomacromolecules. Therefore, modern science can not only use terahertz (waves) as a diagnostic medium to diagnose many physical and chemical reaction processes, but also use it as an information wave to achieve certain communication needs.
Yingshu took three deep breaths before speaking: "1G communication is a technology that transmits a few Kbps of information. After 41 years of development, the current 5G maximum download rate can reach 1Gbps. 1G is 1048576KB. This speed of progress can be said to be rapid, and the corresponding frequency of the radio electromagnetic waves we use is also constantly increasing.
Because in theory, the higher the frequency, the larger the bandwidth range allowed to be allocated, and the greater the amount of data that can be transmitted per unit time. The frequency of terahertz waves is 1 to 4 orders of magnitude higher than the microwaves currently used. It can provide a wireless transmission rate of more than 10Gbit/s, which is a height that microwaves cannot reach.
Six years ago, the Neon NTT Group announced the development of a radio frequency chip in the terahertz frequency band and conducted high-speed data transmission experiments. They claimed that the radio frequency chip allowed the experimental peak rate to reach 100 Gbit/s.
In addition to Neon, the German Federal Institute of Physics and Technology, Bell Labs, University of Toronto, IEMN, and Asyrmatos Communications Systems have also invested a lot of energy in terahertz technology research.
Although our department had related research four years ago, it was limited by resource investment and semiconductor technology, so we did not make much progress in the terahertz project. "
Dull.
When Yingshu said this, it was obvious that the atmosphere in the conference room was a little stagnant.
So many elite senior executives put down their complicated scientific research tasks and came here for a meeting, but they didn't even have a foundation and started to "dream"?
"However, these predicaments finally had some solutions last year, under the unstoppable charge of the semiconductor department, with the encouragement of Mr. Gu and the help of the company's think tank team.
The wavelength of terahertz is about 30μm-3mm, which is much smaller than the wavelength of microwaves and millimeter waves used by 5G, so it can achieve higher precision and also has the characteristics of high resolution, strong penetration and strong anti-interference ability.
At present, the world is developing terahertz frequency band radio frequency chips. Although the achievements claimed by the Japanese NTT Group are very strong, we have not seen a physical device so far. The academic community believes that this is another "exaggerated speech" by Japan, in order to attract investment and attract attention, and to gain the right to speak.
Everyone should know that the most important thing about radio frequency chips is not software programs, but chip performance.
Our Jiuzhou Technology Semiconductor Department now has the world's top carbon-based chip technology, while Japan, Germany, the United States, and France are still using silicon-based chip technology to develop radio frequency chips, which is only one version away from us from the basics."
Speaking of this, Yingshu naturally adjusted his black-framed glasses.
Then he went on to say: "Terahertz processors, including terahertz RF chips, can not only be used in the field of communication engineering, but also in full-scene imaging systems. It allows the device to see through smoke and ordinary materials for true perspective shooting.
From the current carbon-based RF chip process performance that we can achieve, the development of carbon-based integrated circuits can be competent for signal amplification within 1500GHz, frequency multiplication, mixing, frequency locking, phase locking and detection within 600GHz.
These parameters are more than one level higher than the performance that can be achieved by international silicon-based chips, and they are all basic functional modules for realizing terahertz signal transmission and reception.
But the problem is that the terahertz RF chips we use now are very powerful and safe, but we still haven't designed and developed them. The matching system framework, 6G communication engineering has encountered a big difficulty here.
Our satellite is now ready for the next test, just like a war is about to break out, our planes are ready to take off, and the cannons are arranged on the designed units, but we have no ammunition! We don’t know how to launch weapons safely and accurately
I am just an ordinary young man studying mathematics. From the overall strength of the entire academic community, I am just a primary school student who has just started, but Mr. Gu trusts me and gives me the most core and important mathematical tasks of the 6G project, but in such a big project, I feel the insignificance of the individual.
The formulas and derivations you see on the blackboard today are the crystallization of the achievements of our department over the years.
