Chapter 250 Cisco, about to faint from crying!
Moreover, the communication between them is still a small laser. With the small size of the laser, there are too many things that can block him.
Once sothing blocks the laser, the communication will definitely be interrupted, and the experience at that ti must be very bad.
It doesn’t matter if you can buffer ahead of ti when watching a movie. It doesn’t matter much for a second or two, but if you suddenly lose the Internet for a second or two when you are racing against ti, who can bear it?
Thinking about it this way, they feel that although the prospect of this technology is wonderful and the cost is low, they don't want to use such an unstable technology!
As the reporter's words ca out from the loud speaker at the scene, nearly 20,000 viewers focused their attention on Lin Xuan, waiting for Lin Xuan's answer.
If Lin Xuan can’t answer the perfect solution, just imagine that a bird flying over blocks the light while playing the ga, causing them to be disconnected while playing the ga.
Then they feel that such a network is unbearable. Although they haven't experienced it like that, it's okay for them to imagine the bad mood.
On the other side, Lin Xuan looked at the eyes of those who were anxious or questioning, he shook his head helplessly, and said with a look that you are really making a fuss:
"Can Hantang Technology not think of anything you can think of?
In this case, let show you how to solve the problem of signal interruption caused by the obstruction of wireless optical communication in the form of video. "
As he spoke, a video with special effects appeared behind Lin Xuan.
In this special effect video, there is a video of a flying bird causing Internet interruption.
What appeared at this ti was a picture of a chip sensing that the signal was interrupted in an instant, and then sending the signal from another wireless optical communication facility.
There is also a capitalized special effect in it, which is the total ti it takes for the chip to receive the signal from the montary interruption, and then send the signal from another wireless optical communication point and deliver it.
"2ms?!
Just two milliseconds? ! "
Among the nearly 20,000 spectators, many bigwigs in the front row let out exclamations.
Among them, Chambers, the president of Cisco, made the loudest exclamation. At this ti, his complexion was already livid.
From feeling the signal interruption to sending the signal from another wireless laser communication device in an instant, he actually thought of the point that wireless optical communication can continue.
But I didn't expect that the reaction speed was so fast, it was only 2ms!
A faint smile appeared on the corner of his mouth, Lin Xuan said with a smile:
“As you can see, when a bird flies by and our signal is suddenly interrupted, our intelligent system will instantly change the signal from one transmission point to another transmission point.
The whole process is only at a speed of 2ms or two milliseconds, which is equivalent to one 500th of a second, which is less than a second.
When we play gas, we don’t notice it at all, so you don’t have to worry about how to continue communicating when our signal is interrupted when a bird flies by.
And the most important thing is that compared with traditional optical fiber communication, one of our biggest advantages is that our networking cost is extrely low!
Signal networking tends to adopt the mode of redundant equipnt. You don’t have to worry about the problem of slowing down due to congestion due to bandwidth grabbing after the signal is blocked. "
"Papa papa papa papa papa papa..."
Hearing Lin Xuan's words, the scene burst into warm applause.
Through the video just now, I saw that it only took two seconds to switch to another signal point for transmission, which successfully solved the problem of the network speed disconnection caused by the flying bird blocking the laser.
The audience at the scene applauded excitedly, the applause was exceptionally warm, and people's eyes were full of eagerness to use wireless optical communication equipnt.
It can instantly switch to another signal transmission point and complete the transmission within two milliseconds. This ultra-fast response speed dispels people's worries.
A re two milliseconds doesn't affect anything at all, so they feel that this technology is no longer disgusting, but a technology that changes the world.
But at this ti, the reporter seed to think of sothing, and he couldn't help but said:
"Mr. Lin, although you have solved the problem of signal interruption caused by passing birds by switching to another signal transmission point in an instant.
But in the face of severe weather, what should we do with ultra-long-distance wireless optical communication?
For example, in dense fog and heavy rain, the fear of refraction of light, once there is dense fog and heavy rain, wouldn’t we be unable to access the Internet at that ti? "
Hearing the reporter's words from the loudspeaker, the applauding people at the scene stopped abruptly!
yes!
Although the form of intelligently switching signal transmission points solves the problem of being afraid of being blocked by birds passing by to block signal transmission.
But in the face of rainy and foggy weather, there is really no way for this ultra-long-distance wireless optical communication technology. Wouldn’t everyone be unable to access the Internet at that ti? !
So while people were a little depressed, they all turned their attention to Lin Xuan, hoping that Lin Xuan could co up with his solution.
“Don’t worry about the foggy weather. We have made targeted designs when developing products, as long as it’s not the kind of heavy fog that is so severe that you can’t see the car level 50 ters away.
Our lasers can penetrate ordinary clouds and fog, because we do not use ordinary lasers, and we have designed them accordingly when designing.
As for rain, our wireless laser communication system can still work in light rain or even moderate rain, but because raindrops will interfere with the laser.
If the signal transmission fails, we will need to send the signal a second ti or even a third ti...
So when it rains, our Internet bandwidth will inevitably drop. As for heavy rain or even heavy rain, there is no way. "
Speaking of this, Lin Xuan sighed. The cloudy weather is fine, and the laser has a good effect on penetrating the cloud.
However, in the face of heavy rain and even heavy rain from God, the wireless laser communication is sowhat weak, because when it rains heavily, the raindrops are too dense and the laser light will be seriously refracted.
This is an extrely bad situation for laser communication.
The distance between the lasers is more than ten kiloters or even tens of kiloters, and the deviation between them cannot be greater than ten milliters.
In this case, if you still force the raindrops not to deflect the laser to other places, it is really difficult.
"But everyone, don't worry, although our wireless optical communication is afraid that heavy rain or even heavy rain will cause the signal to be interrupted due to the refraction of too dense raindrops.
But isn’t there still fiber optic communication in this world? In such a situation, everyone will automatically switch to the wired optical fiber or wired telephone line Internet access mode in an instant.
Although the Internet bandwidth will beco a little congested, and everyone will experience a forced drop in network speed, this does not affect us to continue surfing the Internet! "
Hearing Lin Xuan's words, although people were a little disappointed, they nodded slightly to express their approval.
So although they felt a little disappointed, they still applauded enthusiastically.
"Papa papa papa papa papa..."
"Damn, **** wireless optical communication technology!"
Seeing this scene, Chambers clenched his fists angrily.
Although this wireless optical communication technology has the disadvantage of being afraid of heavy rain, heavy rain and even dense fog, its cost is very low. Once it is described as large-scale popularization, the Internet bandwidth will be unprecedentedly abundant!
This is a technology that changes the world!
Cisco President Chambers said bitterly at this ti:
"This ultra-long-distance wireless laser communication technology will complent optical fiber communication, and it is destined to tear a large piece of at in the optical fiber communication technology market in the future!"
Although this technology is afraid of dense raindrops at the heavy rain level and even ultra-high-density clouds and fog, it doesn’t rain all the ti.
And if people are at ho on rainy days, they must unplug electrical appliances to prevent lightning from burning them down.
The birth of this ultra-long-distance wireless laser communication technology may beco the mainstream communication technology in the world!
At that ti, Cisco's optical fiber communication technology will naturally beco the end of the market, as a supplent to wireless optical communication technology!
Thinking of this, Chambers, the president of Cisco, looked bitter.
Why did Cisco beco the number one company in the world before? Successfully surpassed Weisoft, surpassed Intel, surpassed IBM...
At the peak, the market value reached 540 billion US dollars, becoming the company with the highest market value in the world?
The reason is that Cisco has mastered the standards of the Internet, that is, it has mastered the relevant patents and standards of optical fiber technology and other Internet communication equipnt and facilities.
It can be said that the global Internet is in the palm of your hand. In this case, Weiruo, Intel and even IBM are simply little brothers.
At this ti, Lin Xuan developed wireless optical communication technology, which has the advantages of ultra-low networking cost and huge Internet bandwidth, and perfectly crushed optical fiber communication technology.
Although he is afraid of heavy rain, heavy rain, and even heavy fog, Chambers believes that broadband operators will not mind the advantages of ultra-low network construction costs and huge bandwidth!
How much does it cost to build a wireless laser communication tower? How much is it to lay fiber optic system...
Every ti Chambers thought about this question in his heart, he felt deep fear and trepidation.
This ultra-long-distance wireless optical communication technology will definitely change the world!
I am afraid that Cisco will plumt from the current top 5 companies in the world by market value, and it will be a reasonable ending for Cisco to fall to the top 50 in the world!
Thinking of this, Chambers felt infinite bitterness in his heart.
On the other side, Lin Xuan did not stop his words. After introducing the wireless optical communication technology at the town level, he introduced the wireless optical communication technology at the county level.
The principle is the sa, and the structure is still the sa, but this ti the height of the wireless optical communication pole is even higher, reaching a terrifying height of 2000 ters!
Chambers, who was in the VIP seat in the front row, listened to Lin Xuan's introduction of the communication between the county seat and the county seat, and the communication between the county seat and the city, and Chambers felt even more bitter.
He deeply felt that Cisco really hit the iron plate this ti.
Wireless optical communication may eventually replace optical fiber communication and beco the mainstream of the market. At that ti, wireless optical communication technology may tear off 80% of the market share of optical fiber communication technology, leaving the remaining 20% for optical fiber communication.
Thinking of this, Chambers' mood is getting more and more depressed. At this ti, he feels that Cisco's decision to provoke Lin Xuan is really a regrettable decision.
He shouldn't have listened to the bragging of Edward Motorola in the first place, he should have insisted on a neutral position.
Maybe if he didn't offend Lin Xuan at the beginning, then Lin Xuan might not develop wireless optical communication technology in the end.
Thinking of this, Chambers felt more and more regretful in his heart, and his mood beca more and more depressed. However, when Chambers thought that this press conference might end like this.
Lin Xuan suddenly changed the subject, and the projection screen behind him turned into a picture of the countryside in an instant.
Seeing this, people looked at the projection screen curiously, with puzzlent and curiosity in their eyes, wondering what Lin Xuan would announce.
Lin Xuan has just released the town-level wireless optical communication technology, and also released the county-level wireless optical communication technology. What else is he going to release at this ti?
