Chapter 233 Shocked TV viewers


    Because it can almost transmit directionally like aser whenmunicating, and transmit towards a point or even a surface, so security is one of the advantages in the field of visible lightmunication.


    Although there are many advantages, wireless opticalmunication technology also has a fatal shoring of being afraid of being blocked!


    It is also because of this shoring of being afraid of being blocked that wireless opticalmunication technology has not improved much until now.


    It is only used in some special asions, such as military support asions and some nichemunication asions, such as TV infrared remote control and so on. "


    Hearing the words of the Xiahua University professor, the audience nodded slightly.


    Facts seem to prove that the words of the Xiahua University professor are true this time, if this technology has no fatal ws.


    Such a good technology must have entered people''s lives a long time ago, and wireless opticalmunication technology will not be seen only in TV remote control as it is now.


    "Professor He, besides the fear of being obscured, is there any other reason to prevent this wireless opticalmunication technology from entering our lives?"


    The hostess asked the questions that came to people''s minds at the right time.


    “In addition to being afraid of being blocked and causing the signal to be interrupted, there are actually other restrictions, such as the miniaturization problem of wireless moduleponents!


    You may not know that, in fact, two years ago, in 2003, more than ten well-known internationalpanies in Han Country, Ind Country and Medi Country established the VLC Alliance.


    Members in this alliance include more than 10 internationalpanies such as Sanxing, Songxia, Sanleng, and Casio.


    The purpose of this VLC alliance is to develop visible lightmunication technology, and the purpose, like Lin Xuan, is to use this technology to rece microwavemunication technology.


    But you all know the result. Two years have passed, and many international giantpanies have jointly developed it for two years, but there is still no result!


    The biggest problem that troubles them is not the standard patent issue of visible lightmunication. After all, the standard is just a set of self-defined rules.


    With the strength of more than a dozen internationalpanies, they have alreadypleted the standard formtion of visible lightmunication.


    But there was one thing that blocked their way forward, and made the huge scientific research funds they invested go to waste!


    This problem is how to sessfully reduce the entire set of visible lightmunication systemponents into small parts for marketization.


    So two yearster, they haven''t released anything yet, and they have burned tens of millions of dors in research funds. "


    "Is there a problem with the miniaturization ofponents?!"


    The hostess in front of the TV, including the audience at the scene, nodded slightly.


    They seemed to understand something, but in fact they didn''t understand anything at all. They could only nod their heads blindly to show that they had finished listening.


    In fact, they don''t know how difficult this miniaturization problem is. Later generations of Chinese scientists have also conducted research in this area.


    It took 7 years to spend countless funds and manpower to solve this technical problem, and sessfully reached the world''s leading level in this field.


    As for the VLC alliance, which was the earliest research, they actually almost gave up when they faced this problem.


    So the great Xia of theter generations can sessfully solve the problem of miniaturization ofponents andrge-scale integrated mass production, and sessfully catch up with the pioneer of VLC Alliance.


    Achieved a transmission speed of 50GB per second forboratory devices and 10GB per second for civilian devices, achieving a world-leading level!


    "Professor He, if Lin Xuan can really ovee these defects, what can wireless opticalmunication bring us?"


    The hostess asked the second important question in this talk show.


    "If Lin Xuan can really ovee the various shorings of wireless opticalmunication technology, then visible lightmunication has great potential!


    It can even be said that it has excellentplementarity with wirelessmunication technology. After the two converge, wirelessmunication technology will be more powerful. "


    "Can you be more specific?"


    The hostess showed curiosity and asked Professor He.


    Nodding slightly, Professor He from Xiahua University slowly said:


    “For example, the biggest difference in signal diffusion between wirelessmunication and visible lightmunication is that a signal concentrates on one surface or point, and a signal spreads in all directions.


    If there are too many microwave radiomunication devices spreading in all directions.


    Then you can imagine the bad effect of countless identical signals in the surrounding environment.


    It''s like throwing a bunch of things together and cooking porridge, which obviously affects the use of wireless devices.


    In order to solve this problem, scientists can only solve it in a stupid way.


    If one transmission fails, do it twice, and it is necessary to repeatedly verify whether the signal packet is lost.


    The final performance result is that when there are few people, it is very smooth to use mobile phones to surf the Inte, but when there are many people or in the case of dense crowds, the wirelesswork speed is really bad.


    This is the natural defect of radio technology!


    After all, his signal spreads in all directions, and it will inevitably affect other devices and cause serious interference.


    Wirelessmunication technology has no such disadvantages, because the transmission direction of light is directional, so it can keep the device in a super high theoretical working condition.


    The result shown is that its stability is very strong, which means that itswork speed can always run to the full theoreticalwork speed state, which is its biggest advantage.


    I did a mathematical calction yesterday, if I use opticalmunication technology, because I am not afraid of the interference of wireless signals from other wireless devices.


    So under the same circumstances, the actualwork speed of wireless opticalmunication technology will generally exceed 4~5 times that of radio microwavemunication technology!


    Based on the current situation, once the wireless opticalmunication technology can really be implemented, there will be no problem with a stable transmission speed of 1G~2G per second! "


    "What? It''s okay to reach a speed of 1G~2G per second?!!"


    A young man at the scene eximed, thework speed of this wireless opticalmunication technology far exceeded his cognition.


    The previous WIPI wireless LAN’s speed of 600 megabytes per second has shocked the world. Now it is no problem to hear that thework speed of a wireless opticalmunication technology can reach 1G~2G per second.


    The young man just felt dizzy for a while. Thework speed of this visible lightmunication technology is too terrifying.


    Thinking of this, he couldn''t help thinking about what he could do with this terrifying inte speed once this technology was applied.


    First of all, the first thing that came to his mind was undoubtedly to use it to download movies and study the teacher''s lessons, but he shook his head again in a sh.


    How can such a terrifying Inte speed be used to download movies and learn knowledge? Shouldn’t this Inte speed be used to y games? This is the right way!


    On the other side, Professor He from Xiahua University shook his head slightly at this time and smiled:


    "It''s a pity, the future of wireless opticalmunication technology is very good, but it''s just a distant dream. We don''t have to think too much, just do what we should, and don''t have too much hope for Lin Xuan.


    After all, just the shoring of fear of being blocked can put this wireless opticalmunication technology on the shelf, so that this technology will never have the possibility ofnding, and it will always be just a distant dream!


    So I am not optimistic about Lin Xuan''s attempt to rece radiomunication technology with visible lightmunication technology. I have to say that Lin Xuan is really a bit ignorant this time.


    But there is no way around this, after all, he was sued by the WiFi Alliance for infringing on their WIFI patent.


    Facing the situation that WiFi-rted patents cannot be used in the future, Hantang Technology can only go to the doctor in a hurry.


    Taking advantage of the fact that there are no patents in the field of wireless opticalmunication, it is impossible to develop wireless opticalmunication technology.


    I believe that if Lin Xuan had a choice, he would never choose to develop wireless opticalmunication technology.


    But no matter what, Lin Xuan really made a stupid decision this time.


    Although this decision was not his subjective will, it was a panicked choice in the midst of rushing to the doctor.


    But until now I have not heard him announce that he has given up research on wireless opticalmunication technology. This proves that Lin Xuan is really desperate for face, and he refuses to admit that he did something wrong...


    I believe that the future Hantang Technology will definitely suffer from Lin Xuan''s behavior. "


    Speaking of this, Professor He shook his head slightly, as if feeling mncholy for Hantang Technology.


    It seems that he is an absolute supporter of Hantang Technology, and it is sad for Hantang Technology to have Lin Xuan, who has no ambition at the helm.


    But he obviously overlooked that if Lin Xuan was not at the helm, Hantang Technology would be just an ordinary mobile phone factory.


    The audience in the audience, including the audience in front of the TV, heard the words of this Professor He, and they couldn''t help feeling sorry for the huge amount of money Lin Xuan had invested.


    Based on Lin Xuan’s character, this fund will definitely be invested in this field with real money, and real money will be invested in research. In this case, the disadvantage of visible lightmunication is that it is afraid of being blocked.


    The final result may be there, but it is definitely not satisfactory, and it cannot rece the status of radiomunication, and the final harvest is very little.


    So this fund may really be wasted!


    Thinking of this, people feel sorry for the money Lin Xuan burned for nothing.


    It turned out that such a huge amount of funds was spent in vain and burned, and the results of the final research and development could not be used. This has to be said to be a tragedy.


    While sighing, they couldn''t help agreeing with Professor He''s words. Lin Xuan''s behavior was indeed a bit reckless.


    Perhaps Lin Xuan should give up the field of wireless opticalmunication and devote all the energy of thepany to the field of microwave radiomunication.


    Directly abandon the relevant technical standards of the WiFi Alliance, 2.4G, 5G, and directly develop 3.5G or 4G and 6Gmunication technologies.


    The only way to establish your ownmunication standards from scratch is the correct path.


    "Pity."


    In front of the Daxia TV, a young man shook his head, feeling sorry for the funds that Hantang Technology had burned.


    "Lin Xuan was really impulsive this time."


    In front of a TV in Daxia, a middle-aged man shook his head slightly, feeling sorry for the funds Lin Xuan had burned.
