At the same time, it is not only the Sike company that has a solemn face, but also other Intel, Suo Ni, Motorcycle Gongla, and Sanxing...... The presidents of giant companies and other giant companies all had solemn expressions

Seeing that the staff on the stage had finished assembling, Lin Xuan turned his head to look at the tens of thousands of spectators and nearly 2,000 reporters who had come over to look curiously and said:

"I said last time that I was going to replace microwave technology with wireless optical communication technology, and I wanted to make the WiFi Alliance guys regret it, and now I finally handed in a preliminary answer."

"The Evil God"

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 it be claimed to make those WiFi Alliance guys regret it! ”

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

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

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

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

The volume of this phone is not a little big, but a little too large.

At this time, Lin Xuan held him in his hand like holding a big brick, and its volume was the same as the big brother's mobile phone released by the motorcycle.

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

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

"As you can see, this mobile phone is currently the first generation of test machine, so it adopts the mode of 4 mobile phone collection and transmission signal points......"

"Oh, that's it!"

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

At the same time, Liang He, president of Moto Gongla Asia on the other side, 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 the motorcycle."

In the crowd, Liang He showed a sneering look and muttered.

At the beginning, he was worried that Lin Xuan would break out some black technology, but after seeing the super-large brick mobile phone, he was not worried.

Because no matter what, just this huge volume, the application scenario of wireless optical communication technology has nothing to do with motorcycle gong.

So he showed a sneering look, and he was deeply relieved in his heart.

At this time, the staff finally completed the relevant tests of wireless optical communication, and then the results were revealed in front of 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 do they see?

They saw a terrifying internet speed!

In their line of sight, they clearly saw that the staff member was operating a laptop.

Dragged a 10GB MP4 file in front of everyone and threw it into a box labeled "Mobile File Sharing".

Then, in less than 1 second, the 10GB MP4 movie was actually transferred and shared?!

People see all this and only feel like they are in a dream, is this internet speed science?!

A 10GB movie was delivered in less than 1 second?!

！

Isn't this network speed a little unscientific?

Looking at those stunned expressions, Lin Xuan shook his head slightly, looking like you were really making too much fuss.

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

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

In 2015, I Daxia has successfully achieved a 50Gbps network speed of visible light communication technology in a laboratory environment, that is, a transmission speed of 50GB per second!

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

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

So now this little bit of internet speed is naturally nothing.

"How is this done?"

Chambers, the president of Siko, looked at the phone with a blank look of disbelief in his eyes.

"It's not scientific!"

Liang He, the president of the motorcycle gong in the front row, said his opinion with a sluggish face.

This network speed is too terrifying, terrifying beyond his imagination, so terrifying that it makes him tremble!

At the same time, it was not only the president of Sike and the president of Moto Gongla who were in a state of shock.

The presidents of other Suo Ni and Sanxing companies, as well as the presidents of Intel, also showed shocked expressions.

In this regard, the corners of Lin Xuan's mouth hooked up a surging smile.

Slowly taking a few steps forward, facing those shocked glances, Lin Xuan said with a smile:

"As we all know, microwave radio communication has a characteristic that its signals are self-centered and emit their radio signals in all directions.

This creates a problem that works well with a single device.

However, if there are more communication devices, the network speed of a single communication device will definitely be very embarrassing.

That's why in a laboratory setting, scientists have measured a very impressive internet speed.

But when we actually experience the product after purchasing, we will regret to find that it can't run the Internet speed that others run out of!

Because people's test environment is very pure, and there are all kinds of 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 this distraction is not something we can touch at all, it does exist all the time, and in the end, our experience is not as good as we imagined.

This situation exists no matter which radio equipment, even our Octopus and Cube routers with WIPI wireless LAN standards!

Our Octopus and Cube routers are in relatively quiet radio areas, such as the last time we tested, the internet speed was 600M per second.

But in fact, in the living environment of daily homes or company factories, the speed that you can actually experience is between 450~550M.

Among them, the network speed of 50M to 150M that disappeared was due to the interference of wireless signals! ”

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

"Wireless optical communication technology also has the characteristics of emitting from all directions like microwave communication.

But the biggest feature of his wireless microwave cable is that its transmission is stable, and he is very less affected by other optical signals! ”

After a pause, looking at the people who showed puzzled eyes, Lin Xuan tried to convey his meaning in more concise words:

"Let's put it this way, in radio equipment, in addition to the interference of similar wireless devices, we live in an environment in fact, many things will also give birth to wireless interference.

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

Therefore, 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?

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

In the end, we experienced that because there was no signal loss, we were able to run almost the full theoretical speed! ”

Looking at the people who finally showed their suddenly realized eyes, Lin Xuan said with a smile:

"Therefore, the advantage of our wireless optical communication technology is that we are not afraid of interference and there will be no loss of signal packets.

Therefore, 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:

"Say it."

Nodding slightly, the reporter slowly opened his mouth and asked, under the curious gaze of the people:

"The speed of the wireless optical communication device you have developed is terrifying, and it is simply breaking the fastest wireless communication network speed in history.

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

But in our daily life, wireless can never always let this mobile phone point at that big light bulb.

Although we can experience the speed of flying, it is really inconvenient. ”

Hearing the reporter's words, many people at the scene nodded their heads and felt a little disappointed.

The truth is that as the reporter said, the Internet is fast, but they just need to imagine that they are holding a mobile phone.

And then the phone must also be exposed to the light and not be blocked, just thinking about it makes me feel so tired holding the phone like this.

In this regard, mobile phones with wireless optical communication technology are not as good as mobile phones that support WIPI wireless LAN!

If they use a WIPI phone, they can do whatever they want, even if they have their back to the light, it doesn't affect them from using the phone to surf the Internet.

So at this time, as this reporter pointed out the shortcomings of wireless optical communication technology that they are afraid of being obscured, they feel that although this technology is fast, it is not very useful!

At this time, Liang He, Chambers, Boss Li, and Nobuyuki Izumoto, who were in the front row of the audience, also reacted instantly after hearing 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 obscured.

Although the network speed of this wireless optical communication technology is very terrifying, just such a weakness can directly kill this wireless optical communication technology, so that it will never be able to raise its head!

"I've thought of what you guys thought of a long time ago."

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

In the eyes of people's curiosity, Lin Xuan held the mobile phone in one hand empty, and picked up a fan in the other hand to cover the oversized mobile phone, leaving the mobile phone in the shadow of the light bulb.

"Do you think you can still communicate now?"

Lin Xuan asked the tens of thousands of viewers with a smile, and those viewers shook their heads one after another.

The mobile phone was blocked by the fan, and it would be abnormal if the mobile phone could still communicate with the big light bulb.
