Chapter 249 The terrifying ultra-long-distance wireless opticalmunication technology!


    In addition, because our wireless opticalmunication equipment is wireless opticalmunication, there is no need to erect a signal transmission device outside.


    It can be directly hidden inside the high pole and directly insted from the outside air, so you don’t have to worry about this thing causing lightning and potential safety hazards. "


    Hearing Lin Xuan''s words, the people at the scene nodded slightly again.


    People have epted Lin Xuan''s words, and they have let go of their worries about the safety of lightning strikes, so their minds turned to wireless opticalmunication.


    Lin Xuan once said that this thing can increase Daxia’swork speed to the fastest level in the world and reduce the cost of broadband infrastructure. I wonder how effective it is?


    If Lin Xuan does it, then Lin Xuan may change the world.


    That’s right, it’s not just changing Daxia, but changing the world. People at this time believe that if this technology can really reduce the demand for infrastructure construction.


    To reduce the cost of infrastructure construction, it may be that all enterprises in the world will need the wireless opticalmunication technology of Hantang Technology.


    “If this technology can really be applied and born, it may change the world.”


    At this time, in the auditorium in the front row, a woman who looked like a secretary looked at the 800-meter-high wireless opticalmunication facility on the stage that was being struck by lightning but remained motionless. He said something with a face full of panic.


    Regarding this, at this time, Chambers of Cisco Company was very happy to have caught Lin Xuan''s w.


    I saw him shaking his head with disdain, turned around and patted his secretary with a sneer and said:


    "It''s just a gimmick. Although super tempered ss with super resistance is used instead of ordinary steel, the cost is extremely low to a certain extent, and with various lightning protection methods, you will no longer be afraid of lightning strikes in the future.


    But this thing is not only afraid of lightning strikes, everything will be fine, he is also afraid of cloudy weather and the possibility of signal interruption caused by passing birds or insects!


    The name of this thing is the town level. ording to Daxia''s definition of the town level, the distance between towns is at least a dozen kilometers.


    In this case, the ultra-long-distance wireless opticalmunication is too easy to be interfered, let alone the interruption of signal interference caused by cloudy weather.


    That is, what will happen if there are birds passing by during the signalmunication? Although it is only a moment for a bird or an insect to fly by.


    But coupled with the detection of a signal interruption, followed by a corresponding retransmission response, it has reached more than a second.


    In this case, I am not optimistic about the ultra-long-distance wireless opticalmunication technology, which is too susceptible to interference. Although the ultra-long-distance wireless opticalmunication technology looks very promising.


    But because it is too easily disturbed by the environment or external factors, it must be a joke in actual use.


    This thing is not as stable as Cisco''s optical fibermunication technology. Unless someone breaks the optical fiber or the equipment is damaged, our optical fibermunication technology will always be stable! "


    Speaking of which, Chambers, the president of Cisco, showed a confident smile, as if he had caught Lin Xuan''s braid.


    At this time, under a series of blows from Lin Xuan, he regained a little confidence seeing Lin Xuan''s braid.


    And Cisco is not the onlypany that thought of this, there are many people who actually thought of this.


    Because many experts were bragging about the ws of wireless opticalmunication technology before, they would naturally instinctively think what to do if this thing is blocked and the signal is interrupted?


    This ultra-long-distance wireless opticalmunication technology can be different from the indoor short-distance wireless opticalmunication technology just now.


    This thing is directly exposed to the external atmospheric environment, which ispletely different from the wireless opticalmunication technology used indoors before.


    The wireless opticalmunication technology in the indoor environment cleverly uses reflection points, and the invisible lightmunication technology and intelligent adjustment mode greatly make up for the shorings of the wireless opticalmunication technology.


    As for this kind of ultra-long-distance wireless opticalmunication of more than ten kilometers, they have no way to reflect.


    Being able to carry out wireless opticalmunication with a distance of more than ten kilometers must usesers, due to the small size ofsers.


    At this time, a bug with a size of a few millimeters may be able to block the signalmunication. At that time, wireless opticalmunication is just a joke!


    So at this time, there were many personal opinions among the nearly 20,000 viewers, and these opinions were passed to the ears of others.


    Soon, as if one word awakened someone from a dream, many people also discovered that this ultra-long-distance wireless opticalmunication technology does have a huge w.


    So they couldn''t help discussing with each other, and then there were many people discussing, and such discussions would trigger a chain reaction.


    As a result, in just over 10 seconds, while Lin Xuan was still introducing, the scene of the press conference waspletely chaotic, and there were buzzing sounds everywhere...


    Looking at the situation where people were scrambling to discuss, Lin Xuan shrugged helplessly, and it seemed that he was going to directly enter the topic.


    So Lin Xuan lightly clicked the remote control in his hand, and the projection screen behind him switched from the picture introducing the high pole structure of the wireless opticalmunication to an actual measurement video in an instant.


    "Quiet! Quiet!"


    "Everyone be quiet, there is something moving up there."


    "Quiet, be quiet."


    Some of the nearly 20,000 viewers noticed something strange at the press conference, so they all shouted and stopped the people who were talking around them.


    Within a few seconds, the scene suddenly fell silent, and people watched the video curiously.


    At this time, this video happened toe to a dismantling video. This dismantling video is just a demo diagram of the dismantling of a high pole structure for wireless opticalmunication.


    At this time, through the demonstration picture of the wireless opticalmunication high pole, people can clearly see that there are densely packed electronicponents on it.


    There is a wireless opticalmunication device about every half meter between them. At this time, the 800-meter-high pole looks like dense wireless opticalmunication devices.


    Looking at those surprised eyes, Lin Xuan introduced with a smile:


    "As you can see, why did I say that our wireless opticalmunication technology can surpass foreign countries and be the world''s number one.


    The reason for this is very simple, because our Inte bandwidth is very abundant! "


    Speaking of this, Lin Xuan paused slightly, and then exined why he said that:


    "As we all know, although my Great Xia is known as a vastnd and abundant resources, the poption is mainly concentrated in the eastern region, and the poption is also very dense.


    When there are more people, the average allocation to a single bandwidth resource will naturally decrease.


    In order to reduce the bandwidth pressure, we have even restricted the uploading of broadband, which is the only case in the world.


    No way, our poption is toorge, and our Inte users are too many, so we have no choice but to do so.


    If you want to increase bandwidth ording to the previous method, you can onlyy optical fibers honestly, there is no shortcut.


    But now as you can see, because we have solved the miniaturization problem of wireless opticalmunication equipment.


    Manufactured the world''s most advanced silicon opticalmunication chip, so we can plug the ultra-long-distance wirelesssermunication device anywhere in the 800-meter high pole.


    You can imagine that a wirelesssermunication device is arranged every half meter in the 800 meters, so how many wirelesssermunication devices can be plugged into the 800-meter-high wireless opticalmunication pole?


    Compared with hiring arge number of workers to dig tunnels and then deeply bury optical fibers, which bandwidth construction cost is lower. "


    Hearing Lin Xuan''s words, many people''s eyes lit up.


    Calcted in this way,pared with therge amount of money and human and financial costs spent on excavating tunnels and deeply buried optical fibers in the old way, the cost of directly using wireless opticalmunication technology is simply terribly low.


    After all, wirelesssermunication only needs to rece a wirelesssermunication facility, and the cost is terribly low.


    At this time, when a reporter suddenly raised it, he asked curiously:


    "Mr. Lin Xuan, what is the transmission speed of this thing? How much bandwidth can a wirelesssermunication device transmit?"


    Hearing this, Lin Xuan paused for a moment, then slowly said:


    “In terms of long-distance ultra-wirelesssermunication, the standard we adopt ispletely different from that of civilian wireless opticalmunication technology.


    Because there is no need to worry about the problem that the heat cannot be dissipated, its power is greater and more aggressive.


    So the current processing capacity of a single wirelessser-grade silicon photonic chip is 100GB per second!


    In order to enhance the utilization of space resources, our ultra-long-distancesermunication does not use amunication point for a singlemunication, but amunication device for multiplemunications at the same time.


    That is to say, on the ultra-long-distance wirelesssermunication facility at one level, we have not one but a total of eightsers formunication.


    So at present, our singleyer ultra-long-distance wirelesssermunication bandwidth has a transmission speed of 800GB per second! "


    Listening to Lin Xuan''s words, nearly 20,000 spectators at the scene looked at each other, wondering if this number is high or low? Most people are nk.


    But at this time, Chambers, the president of Cisco, showed a shocked expression.


    As the president of Cisco, Chambers is also very familiar with his own Intemunication products.


    Although the singleyer wireless facilities of Hantang Technology have abined bandwidth of only 800GB per second, it is just a jokepared to the mature optical fibermunication technology.


    But the problem is that there is not only one such thing, and many can be arranged on the samemunication pole.


    Think about the 800-meter-high wireless opticalmunication card, how many it can arrange every half a meter, and then think about the cost of building a new high pole...


    Thinking of this, Chambers couldn''t help but feel chills in his heart. The construction cost of such a thing is too low, its expansion cost is too low, and its market potential is too terrifying.


    At this time, he only hopes that Lin Xuan has not solved the fatal w of ultra-long-distance wirelesssermunication, the fatal w of being afraid of being blocked and causing the signal to be interrupted!


    If Lin Xuan really solves that fatal w, then this technology will no longer be a theory.


    Instead, it can really enter people''s lives. At that time, I am afraid that the globalmunication market will usher in an earthquake!


    Now that we have entered the digital age, the signals transmitted by mobile phones and even many phones are no longer analog signals but digital signals.


    In this case, is it difficult to directly abandon the wired form and adopt the wirelessmunication mode?


    In the future, this thing can not only be applied in the field of Inte, but also directly in the field of mobile phones and even telephones. It can be said that it is almost omnipotent!


    "Mr. Lin Xuan."


    The reporter who asked the question just now raised his hand again. Seeing this, Lin Xuan pondered for a moment and waved his hand, and then the on-site staff handed the microphone to the other party:


    "Mr. Lin Xuan, your wirelesssermunication has a very good prospect, its construction cost is also very low, and thework speed is also very fast, even better than we expected.


    But our earth is just us humans, and there are other harsh environments, such as dense fog, flying insects, birds and so on.


    Although the altitude of 800 meters is a bit high, it is nothing to some insects or even birds. When they pass by, the signal may be interrupted. What should we do at that time? "


    Hearing this reporter''s words, many people now recall their earlier fears.


    Yes, this thing is wireless opticalmunication. The most feared thing about this wireless opticalmunication technology is being blocked.
