"Send another file."

Lin Xuan turned his head and said to the technician.

Soon, the technician sent a 10GB movie file again in front of everyone.

"Ding!"

Looking at the projection screen showing the image of "Successfully sent", people showed stunned expressions.

What the heck?

Didn't Lin Xuan use a fan to cover the communication between the mobile phone and the light just now? How can you still send the file successfully?!

Although the speed of this transmission is slightly delayed, reaching nearly a second, it does show that the delivery has been successful!

At this time, in order to prove that "the document has been sent successfully".

A person carrying a camera came to Lin Xuan's side and pointed the lens of the camera at the screen of his mobile phone.

At this time, there is an extra movie on the super large straight phone, and two movies are appearing there on it!

In this regard, tens of thousands of spectators and nearly 2,000 reporters at the scene all showed disbelief!

Among them are the presidents of Moto Gongla, Nokia, Sanxing, Sike and other companies!

"It's not scientific!"

Seeing that he had already blocked the light with a fan, he had put the phone in the shadows, but the phone could still communicate?!

The CEOs of these large international enterprises have issued words of disbelief, with puzzlement and shock in their eyes!

"Could it be that when it was covered, Lin Xuan used wireless LAN communication technology to replace the transmission of data?"

Chambers, the president of Cisco, muttered, but soon shook his head.

Because the time for the file transfer just now is only one second, how can it be possible to transfer a 10GB file in one second?!

It can transfer 10GB of files in one second, and only wireless optical communication technology can deliver files so quickly!

"How the hell is this done?"

Chambers, the president of Siko, had a deep puzzle in his eyes.

At this time, he seemed to see an alien black technology, but he couldn't understand how the alien black technology did it and what kind of principle it was!

Onigiri Exploration Book

At this time, he could only keep shouting in his heart: "This is not scientific!" This doesn't make sense! But he didn't have anything to do.

"The secret is actually very simple, and the cost of setting it up is very low."

Lin Xuan smiled and took out a somewhat dull round thing from the wooden wall on the side.

"I see!"

After seeing Lin Xuan take out a stuffy, but not very dazzling thing from a wooden wall.

Chambers, the president of Sike Corporation, had a look of sudden realization in his eyes.

"I really didn't expect to be able to use this to break the game, and the cost is so low!"

Chambers was very annoyed as he spoke.

He didn't even think of such a simple way to crack it, which really violated his identity as the president of Sike Company.

The solution is actually very simple, that is, the principle of using mirrors to reflect light!

The fan did block the direct communication between the mobile phone and the light bulb, and it really couldn't communicate directly according to common sense.

But at this time, if there is a strong reflective light material as a relay that directly reflects the light signal of the bulb, then it is indeed able to allow the mobile phone to continue to communicate!

"It's a genius idea, and it's a great way to compensate for the shortcomings of wireless optical communication technology.

If such reflection points are arranged too much, it can completely allow the mobile phone to obtain the same communication ability as microwave communication, so that the mobile phone is always in the most perfect state. ”

Chambers sighed, but in an instant he furrowed his eyebrows again, and then there was a slight disappointment in his eyes.

"If that's all there is to it, then that's all there is to the technology."

It's a genius idea to place a reflection point, but if the environment is not well arranged, it will make the room look very ugly.

Imagine if you had a lot of obtrusive little highlights hanging on the walls of your home, wouldn't that look sloppy?

They don't look good when they're stuck to the wall.

Although this is a reflective material, it looks obviously treated and will not be as dazzling as some materials with strong light reflective materials, but if it doesn't look good, it doesn't look good!

So although the technology is good, it's just that, and it's ......

The corners of Chambers' mouth curled into a mocking smile, and then he slowly spoke:

"Although the design is very ingenious, the fear of obscuration of wireless light has not been solved, so this wireless optical communication technology still has a fatal flaw."

The other side.

Lin Xuan looked at those curious eyes, he took out an aluminum and iron bucket, directly threw the mobile phone into the iron bucket, and asked everyone with a smile:

"Do you think you can still communicate?"

In an instant, Chambers, who was still mocking Lin Xuan just now, was like a duck pinched by the neck, and his face instantly froze.

"It's impossible, it's impossible to communicate!"

Chambers, who was stunned, slowly spoke his words.

The phone has been dropped at the bottom of that plastic bucket, and although the plastic bucket may also reflect light, the plastic bucket is not very reflective, and they can't still communicate in this case!

At the same time, it is not only Chambers, the president of Sike Company, who holds such a view, but also the boss Li of Sanxing Electronics who gives the same view.

"Go ahead."

Lin Xuan turned his head and said to the staff.

"Roger."

The staff replied with a smile, and then manipulated the mouse to send a file to Lin Xuan's mobile phone again.

"Didi!"

As soon as I dragged the mouse to send, a "Failed to send" prompt appeared on the screen of the computer.

"Sure enough!"

While the tens of thousands of spectators at the scene were stunned, Chambers, the president of Siko, breathed a sigh of relief.

After seeing the "failed to send" prompt box, he breathed a deep sigh of relief in his heart.

It seems that Hantang Technology's technology is not as terrifying as he imagined, which is really good!

The audience at the scene showed disappointed expressions, it seems that this mobile phone is really as experts say, wireless optical communication technology is indeed afraid of being blocked.

At this time, I looked at the phone at the bottom of the plastic bucket, but I saw a "sent failed" prompt box.

The tens of thousands of spectators at the scene all showed disappointed expressions and felt a little lost.

At this time, Lin Xuan picked up his mobile phone on the stage, shrugged his shoulders, and said helplessly:

"Sorry, the storage memory of the phone has been filled up just now, wait until I delete the two movie files I just transferred before testing."

"Huh?!

”

Hearing Lin Xuan's words, the tens of thousands of viewers at the scene blinked with the reporters.

What?

Didn't you just fail?

How did you listen to Lin Xuan's words, it turned out that it didn't fail because of the signal interruption just now, but the memory of the mobile phone was full and couldn't fit it, so it failed to be sent?!

At this time, tens of thousands of spectators and nearly 2,000 reporters all showed stunned expressions.

In this way, in their stunned expressions, Lin Xuan deleted the two movies on his phone in front of the camera.

After putting the phone back in the plastic bucket, Lin Xuan turned his head and smiled:

"Let's move on."

"Okay."

The staff nodded slightly, and then repeated the action just now.

But this time it's completely different from the previous one, this time it shows "Sent successfully", and the whole process only took two seconds!

"Wow!"

There was an uproar at the scene, and the mobile phone could still communicate and transmit files by throwing it into that plastic bucket?!

Tens of thousands of spectators and nearly 2,000 reporters at the scene showed shocked eyes.

At the same time, on the Internet, those netizens who were watching the live broadcast of pictures and texts in real time in the penguin colony or forum also showed stunned expressions!

"It's not scientific!"

Even though he already had a premonition in his heart, when this scene really appeared in front of his eyes, Chambers couldn't help but shout "unscientific" sound.

Retracting his gaze at Chambers, a competitor, Lin Xuan turned his head to look at the lens of the camera and said:

"Our wireless optical communication technology is not as weak as everyone thinks.

Our wireless optical communication technology introduces an intelligent adjustment mode that can adapt to bright and dark light environments and maintain communication.

These smart adjustment modes don't require you to do anything, they do it automatically!

The specific manifestation is our wireless optical communication technology, which has a strong signal transmission ability.

It can almost be said that as long as there is a little dim light, then our mobile phones can intelligently recognize the signal!

To what extent does this intelligent recognition capability reach? Let's speak with facts. ”

As he spoke, Lin Xuan took out a cloth for making clothes and covered the phone, making it airtight.

In response, the staff member nodded slightly, and sent another document in the stunned sight of the people.

"Ding!"

Less than two seconds later, the crisp voice sounded again.

Looking at the prompt box of "Successfully sent", the scene was instantly shocked and in an uproar!

Can you even send documents wrapped in a piece of cloth like this?

This wireless optical communication technology is too terrifying!

"As you can see, our new technology is not as weak as everyone thinks.

Because our wireless optical communication technology is not a simple visible light communication technology, it also includes invisible light communication technology, that is, far-infrared optical communication technology!

In the mobile phone, a device that everyone touches and uses daily, in order to prevent the communication light emitted by the mobile phone communication module from being too dazzling and affecting the perception of use, we prefer to use invisible light communication technology in the mobile phone.

When our mobile phone is in a special environment as just now, that is, when the signal is severely blocked.

Although our mobile phones can't see anything abnormal, in fact, our "communication module" is actually in the brightest far-infrared light communication state!

This "brightest" state can naturally easily penetrate our clothes, after all, our clothes and fabrics look impermeable.

But in fact, they can still have a large gap to penetrate the light, and in this case, there is no problem for the two sides to communicate.

One of the most special is that because we can't recognize such invisible light with the naked eye, this "brightest" invisible far-infrared light is not dazzling, and even our naked eyes can't even detect it! ”

When people heard Lin Xuan's words, they finally understood why they were able to transmit signals when they blocked the light with a cloth.

It turns out that the invisible far-infrared light that is brightened is used to transmit the signal, so they can continue to communicate.

After realizing this, they all showed admiration.
