"From the information I can find, the Bauhinia Mountain Laboratory has indeed created the world's highest real-time transmission record for terahertz wireless communications in an ideal real-world environment.
Terahertz wireless communication is recognized as a core component of the 6G mobile communication system, and the Bauhinia Mountain Laboratory has created a real-time transmission architecture that integrates photonic terahertz optical fiber, achieving a single-wavelength net rate of 103.125Gbps and a dual-wavelength net rate of 103.125Gbps. 206.25Gbps terahertz real-time wireless transmission, the communication rate is 10 to 20 times higher than 5G.
What is the current status of our laboratory? I think we need to know the data in this area. After all, the explanation on the device is not that intuitive. "
The old man who resigned from Xia Ke Academy is obviously a person who pays attention to practical work and foundation.
Although in the scientific research environment of Jiuzhou Science and Technology, the phenomenon of seniority based on seniority has long been smashed to pieces by Gu Qing, no matter how many people here break the rules, they cannot change the fact that they were once students of this old man.
So there was a noticeable pause in the brainstorming session at this point.
Everyone invariably turned their attention to Ying Shu, Li Cun and others, the heads of the 6G communications g engineering department.
After Ying Shu and others received these looks, their shoulders felt heavy.
Although they were all following Gu Qing, as soon as they entered the professional field, the light that burst out from their eyes was extremely dazzling.
The large screen in the conference room also intelligently introduced the relevant knowledge of terahertz and terahertz wireless communications, providing a knowledge base for some participants who did not understand the details.
Terahertz (THz) is one of the frequency units, indicating the oscillation frequency of electromagnetic waves. T is the unit of quantity. 1THz = 1012Hz. Therefore, terahertz generally refers to electromagnetic waves with frequencies in the range of 0.1~10 THz (wavelength is 30μm-3mm). The long-wavelength band overlaps with millimeter waves, and the short-wavelength band overlaps with infrared light. It is not only the transition zone from macroscopic classical theory to microscopic quantum theory, but also the transition zone from electronics to photonics.
Miraculously, the band of terahertz waves can cover the characteristic spectra of semiconductors, plasmas, organisms and biological macromolecules. Therefore, modern science can not only use terahertz (waves) as a diagnostic medium to diagnose many physical and chemical reaction processes, but also It can also be used as an information wave to achieve certain communication needs.
Yingshu took three deep breaths before speaking: "1G communication is a technology that transmits information of several Kbps. After forty-one years of development, the current maximum download rate of 5G can reach 1Gbps. 1G is 1048576KB. This speed of progress It can be said to be rapid, and correspondingly, the frequency of the radio electromagnetic waves we use is also constantly increasing.
Because theoretically, the higher the frequency, the greater 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 that of currently used microwaves. It can provide wireless transmission rates of more than 10Gbit/s, which is a height that microwaves cannot reach.
Six years ago, Neon NTT Group announced that it had developed a radio frequency chip in the terahertz 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, the American Bell Labs, the University of Toronto in Canada, the French IEMN, and the American Asyrmatos Communication Systems Company have also invested huge efforts in terahertz technology research.
Although our department had relevant research four years ago, it was limited by resource investment and semiconductor technology constraints, so it did not make much achievements in the terahertz project. "
Dull.
When Yingshu said this, he clearly felt 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 to hold meetings, but they started "dreaming" without even having a foundation?
“But these dilemmas, with the overwhelming charge of the semiconductor department, with the encouragement of Teacher Gu and the help of the company’s think tank team, we finally had some solutions last year.
The wavelength of terahertz is approximately in the range of 30μm-3mm, which is much smaller than the wavelength of microwaves and millimeter waves used in 5G, so it can achieve higher accuracy, and also has high resolution, strong penetration and strong anti-interference ability, etc. Features.
Currently, the world is developing radio frequency chips in the terahertz frequency band. Although the results claimed by Neon NTT Group are very strong, so far, we have not seen a physical device appear. The academic community believes that this is another exaggerated speech by Neon. ', in order to attract investment and attention, and strive for the right to speak.
Everyone should know that the most important thing about a radio frequency chip is not the software program, but the chip performance.
Our Jiuzhou Technology Semiconductor Department now has the world's top carbon-based chip technology, while Guojia, such as Neon, Germany, America, and France, still use silicon-based chip technology to develop radio frequency chips. Basically, they are one version behind us. . "
Having said this, Wanshu adjusted his black-rimmed glasses naturally.
Then he continued: "Terahertz processors including terahertz radio frequency chips can not only be used in the field of communication engineering, but can also be used in full-scene imaging systems. It can allow equipment to see through smoke and ordinary substances. , for true perspective shooting.
Judging from the process performance of carbon-based radio frequency chips that we can currently achieve, carbon-based integrated circuits can be capable of signal amplification within a frequency of 1500 GHz, frequency multiplication, frequency mixing, frequency locking and phase locking and detection within a frequency of 600 GHz.
These parameters are one level or more superior to the performance that international silicon-based chips can achieve, and they are all basic functional modules for realizing terahertz signal transmission and reception. ,
But the problem is that the terahertz radio frequency chips we use now are very powerful and safe, but we still have not designed and developed a matching system framework. The 6G communication project has encountered major difficulties here.
Our satellites are now ready for the next test, as if a war is about to break out. Our aircraft are ready to take off, and the cannons are arranged on the designed units, but we have no ammunition! I don’t know how to fire weapons safely and accurately.
Personally, I am just an ordinary young man studying mathematics. In terms of the overall strength of the entire academic world, I am just a primary school student who has just started. However, Mr. Gu trusted me and gave me the core and most important mathematical tasks of the 6G project. , but in such a big project, I feel the insignificance of individuals.
The formulas and derivation you see on the blackboard today are the fruits of our department’s achievements over the years.
