Chapter 236: Shocked the audience!

Chapter 236 shocked the audience!

At the same time, Cisco is not the only company that has serious expressions on their faces. The presidents of other giant companies such as Intel, Soni, Motorola, Sanxing...

Watching the assembly of the staff on the stage was completed, Lin Xuan turned to look at the tens of thousands of spectators and nearly 2,000 reporters who had cast their curious eyes and said:

"I said last time that I want to replace microwave technology with wireless optical communication technology. I want to make those guys in the WiFi Alliance regret it. Now I finally handed in a preliminary answer sheet."

After a pause, Lin Xuan continued:

"This time I will show what are the characteristics of our wireless optical communication technology, and why it can claim to replace microwave radio communication technology.

Why can you claim to make those guys from the WiFi Alliance regret it! "

Hearing Lin Xuan's words, people nodded slightly, and the curiosity in their eyes grew.

At this time, Lin Xuan also slowly took out a super-large straight mobile phone with glass edges on all sides from the table on the side, then looked at the audience and said:

"Because it is the first generation of verification technology products, the structure and shape are still in the stage of exploration, so the appearance is a bit ugly, and the volume is a bit too large."

Listening to Lin Xuan's words, people nodded slightly again, and then looked curiously at Lin Xuan's phone.

This mobile phone is not a little big, but a little too big.

At this time, Lin Xuan held him like a big brick in his hand, and its size was comparable to the big brother mobile phone released by Motorola back then.

At this time, people looked at the shiny glass pieces on the four corners of the mobile phone, and people speculated: "Could this thing be a signal collector for wireless optical communication technology?"

It's a little different from what they imagined as a big light bulb on the phone display.

"As you can see, this mobile phone is currently a first-generation test machine, so it adopts the mode of collecting and sending signal points by 4 mobile phones..."

"Oh, that's all!"

At first, he was a little nervous, but after seeing the oversized mobile phone, Chambers, who instantly relaxed, said sarcastically.

At the same time, Liang He, the president of Motorola Asia, also breathed a sigh of relief.

This wireless optical communication technology is not to be feared!

"This phone is a joke, it seems that I don't have to worry about my Motorola."

Among the crowd, Liang He murmured with mocking eyes.

At the beginning, he was worried about some black technology that Lin Xuan would reveal, but after seeing the super-large brick phone, he was no longer worried.

Because no matter what, just because of its huge size, the application scenarios of this wireless optical communication technology have nothing to do with Motorola.

So he showed a sarcasm in his eyes, and he was deeply relieved.

At this time, the staff finally completed the relevant tests of wireless optical communication, and the results were revealed to everyone.

"Wow!"

Seeing the test results on the projection screen, the scene was in an uproar!

People looked at each other with deep disbelief in their eyes!

What did they see?

They saw a terrifying Internet speed!

In their line of sight, they clearly saw the worker operating a laptop.

Drag a 10GB MP4 file in front of everyone, and then drop it into a box labeled "Mobile File Sharing".

Then, in less than a second, the 10GB MP4 movie was transferred and shared? !

People see all this and feel like they are in a dream. Is this internet speed scientific? !

Transfer a 10GB movie in less than 1 second? ! !

Is this internet speed unscientific?

Looking at those stunned expressions, Lin Xuan shook his head slightly, as if you guys really made a fuss too much.

In fact, the transmission speed of that video is really less than one second.

Because the theoretical network speed of the current first-generation Hantang wireless optical communication standard is 10.6Gbps, that is, the transmission speed of 10.6GB per second!

In 2015, my future generation, Daxia, successfully realized the 50Gbps network speed of visible light communication technology in the laboratory environment, that is, the transmission speed of 50GB per second!

And now the network speed of only 10.6Gbps is really nothing, it can only be regarded as mediocre.

Compared with the 50Gbps network speed of later visible light communication equipment in 2015, there is still a gap of about 5 times in network speed.

So now this network speed is naturally nothing.

"How is this possible?"

Cisco CEO Chambers looked at the phone blankly, with disbelief written in his eyes.

"This unscientific!"

Motorola President Liang He in the front row expressed his opinion with a dull expression.

The internet speed is too terrifying, beyond his imagination, it is so terrifying that it makes him shudder!

It wasn't just the president of Cisco and the president of Motorola who were in a state of shock at the same time.

Other presidents of Suoni, Sanxing, and Intel also showed shocked expressions.

In this regard, Lin Xuan's mouth evoked a faint smile.

Slowly took a few steps forward, facing those shocked gazes, Lin Xuan said with a smile:

"As we all know, microwave radio communication has a characteristic, which is that its signal will center on itself and emit their radio signals in all directions.

This creates a problem, which is that it works well with a single device.

But if there are more communication devices, the network speed of a single communication device must be very embarrassing in the end.

This is why in the laboratory environment, the network speed measured by scientists is very impressive.

But when we actually experience the product after purchasing, we will unfortunately find that we can’t run at the same speed as others!

Because the test environment is very pure, and there are various wireless signal devices in the streets and alleys of our daily life, and even in the factory environment.

These wireless signal devices emit their wireless signals all the time, forming a huge interference with each other.

Even if we can’t touch this interference at all, it does exist from time to time, and in the end, the network speed we experience is not as good as we imagined.

This situation exists no matter which radio device it is, even our WIPI wireless LAN standard Octopus and Cube routers also exist!

Our Octopus and Cube routers are in a place where the radio is relatively quiet. For example, the last time we tested, the network speed was 600M per second.

But in fact, in the living environment of your daily home or company factory, the speed you can actually experience is between 450 and 550M.

The disappearing network speed of 50M to 150M network speed is due to the mutual interference of wireless signals! "

After a slight pause, Lin Xuan continued to speak after seeing thoughtful looks in people's eyes:

"While wireless optical communication technology also has the characteristics of emitting to all directions similar to microwave communication.

But the biggest feature of its communication with wireless microwave is its stable transmission, and it is very low affected by other optical signals! "

After a pause, Lin Xuan tried to express his meaning in more concise words as he looked at the people who showed puzzled eyes:

"Let's put it this way, in radio equipment, in addition to interference from similar wireless equipment, in the environment we live in, there are actually many things that produce wireless interference.

And because our wireless optical communication technology is a signal of light, light is more stable and free from interference than radio.

So under the same circumstances, as long as it is not blocked, there will be almost no signal loss in the wireless optical signal.

What does this mean?

means that we send a signal, and the other end can receive the signal accurately, and there will be no signal loss in the middle.

In the end, the result we experienced is that because there is no signal loss, we can almost run at full theoretical network speed! "

Looking at the people who finally showed enlightened eyes, Lin Xuan smiled and said:

“So the advantage of our wireless optical communication technology is that it is not afraid of interference and there will be no loss of signal packets.

So our equipment can run at full theoretical speed, which is the strongest advantage of wireless optical communication technology! "

"Mr. Lin Xuan, can we ask you a question?"

At this time, a reporter in the front row slowly raised his hand.

Looking at the reporter who raised his hand, Lin Xuan frowned slightly but after thinking for a while, he said slowly:

"Speak."

Nodding slightly, the reporter asked slowly under the curious eyes of people:

“The wireless optical communication equipment you developed has a terrifying network speed, breaking the fastest wireless communication network speed ever.

But according to our understanding, wireless optical communication technology is very afraid of being blocked, although the device you develop has a fast network speed.

But in our daily life, we can't always keep the phone facing the big light bulb.

Although we can experience the speed of the Internet like flying, it is really inconvenient. "

Hearing the reporter's words, many people at the scene nodded, feeling a little disappointed.

The facts are indeed as the reporter said, the Internet speed is fast, but they only need to imagine that they are holding a mobile phone.

Then the phone must be exposed to the light and cannot be blocked. Just thinking about it like this makes me feel tired holding the phone like this.

As far as this point is concerned, mobile phones with wireless optical communication technology are completely inferior to mobile phones that support WIPI wireless LAN!

If they use WIPI wireless LAN mobile phones, they can do whatever they want, even if their backs are facing the light, it will not affect their use of mobile phones to surf the Internet.

So at this time, as the reporter pointed out the shortcoming of wireless optical communication technology that is afraid of being obscured, they felt that although this technology has a faster network speed, it is not very useful!

At this time, Liang He, Chambers, Boss Li, and Chuxiang Shinzhi, who were in the front row of the audience, also reacted instantly when they heard the reporter's words.

It is true that although the network speed is fast, wireless optical communication technology has the disadvantage of being afraid of being blocked.

Although the network speed of this wireless optical communication technology is very terrifying, such a weakness alone can directly kill this wireless optical communication technology, making it unable to lift its head forever!

"I have already thought of what you think of."

Looking at those lost sights, Lin Xuan said with a smile, then he slowly turned and walked aside, picking up the mobile phone that was about the size of a big brother.

In people's curious eyes, Lin Xuan held the mobile phone empty in one hand, and picked up a fan with the other hand to cover the oversized mobile phone, so that the mobile phone was under the shadow of the light bulb.

"Do you think you can still communicate now?"

Lin Xuan smiled and asked the tens of thousands of spectators, who shook their heads.

The light of the mobile phone was blocked by the fan. At this time, if the mobile phone can still communicate with the big light bulb, it will be abnormal.
