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

It can be directly hidden inside the high pole and directly isolated from the outside air, so you don't have to worry about this thing being a potential safety hazard. ”

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

People had already recognized Lin Xuan's words, and at this time, they had already put aside their worries about the safety of the lightning strike, so their minds turned to wireless optical communication.

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

If Lin Xuan did it, then Lin Xuan might change the world.

That's right, not just to change the Great Xia, but to change the world, and people at this time believe that this technology can really reduce the need for infrastructure construction.

To reduce the cost of infrastructure construction, it may be that all enterprises around the world will need Hantang Technology's wireless optical communication technology.

"If this technology can really be applied, it may change the world."

At this time, in the audience in the front row, a woman who looked like a secretary looked at the 800-meter-high wireless optical communication facility that was being thundered but did not move at all on the stage, and he said with a frightened face.

In this regard, at this time, Chambers of Sike Company looked happy to catch Lin Xuan's flaws.

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

"It's just a gimmick, although the super tempered glass with super resistance is used to replace ordinary steel, to a certain extent, the cost is ultra-low, and various lightning protection means will no longer be afraid of lightning strikes in the future.

But it's not just that he's not afraid of lightning strikes, he's also afraid of the possibility of signal interruptions caused by cloudy weather and passing birds or bugs!

The name of this thing is town-level, and according to the definition of town-level in Great Xia, the distance between towns is at least ten kilometers.

In this case, ultra-long-distance wireless optical communication is too easy to be interfered with, not to mention the signal interference interruption caused by cloudy weather.

Let's just say what if a bird passes by during signal communication? Although the birds or bugs fly by is only a moment.

However, with the detection of a signal interruption and the corresponding re-emission reaction, it has reached a time of more than a second.

In this case, I am not optimistic about ultra-long-distance wireless optical communication technology, which is too susceptible to interference, although the prospects of ultra-long-range wireless optical communication technology look very good.

But because it is too easy to be disturbed by the environment or external factors, it must be a joke when it is actually used.

How can this thing be stable with our company's optical fiber communication technology, and our optical fiber communication technology will always be stable unless someone breaks the optical fiber or the equipment is damaged! ”

Speaking of this, Chambers, the president of Sike Company, showed a confident smile, as if grabbing Lin Xuan's pigtails.

At this time, under Lin Xuan's series of blows, he regained a little confidence when he watched Lin Xuan's exposed pigtails.

And the scene is not only Sike company thought of this, but actually thought of this many people.

Because many experts have been boasting about the many shortcomings of wireless optical communication technology, in this case, they will naturally instinctively think about what if this thing is blocked and the signal is interrupted?

This ultra-long-range wireless optical communication technology is different from the indoor short-range wireless optical communication technology just now.

This thing is directly exposed to the outside atmosphere, which is completely different from the wireless optical communication technology used in the previous indoor environment.

The clever use of reflection points, invisible light communication technology and intelligent adjustment mode in the wireless optical communication technology in the indoor environment greatly make up for the shortcomings of wireless optical communication technology.

And for this kind of ultra-long-distance wireless optical communication that is more than ten kilometers away, they have no way to reflect the point.

To be able to communicate with wireless optical communication more than ten kilometers away must be the use of lasers, with the small size of the laser.

At this time, a bug a few millimeters in size may be able to block the communication of the signal, and wireless optical communication was just a joke at that time!

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

Soon, like waking up a person in a dream, many people have also discovered that this ultra-long-distance wireless optical communication technology does have great flaws.

So they couldn't help but discuss with each other, and then there were many people discussing, and such a discussion would set off a chain reaction.

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

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

So Lin Xuan lightly clicked on the remote control in his hand, and the projection screen behind him instantly switched from a picture of the high-pole structure introducing the wireless optical communication to a measured video.

"Quiet! Be quiet! ”

"Be quiet, there's movement up there."

"Quiet, be quiet."

Some of the nearly 20,000 spectators noticed something unusual at the press conference, so they shouted one after another, stopping the people who were talking around them.

In less than a few seconds, the scene suddenly fell silent, and people watched the video curiously.

At this time, there is a dismantling video in this video, which is a dismantling demonstration diagram of a wireless optical communication high-pole structure.

At this time, through the demonstration diagram of the wireless optical communication high pole, people can clearly see that there are dense electronic components on it.

There is a wireless optical communication device between them about every half a meter, and the 800-meter-high pole at this time looks like a dense wireless optical communication device.

Looking at those surprised glances, Lin Xuan smiled and introduced:

"As you can see, why did I say that our wireless optical communication technology can surpass foreign countries and become the world's first?

The reason for this is simple, because we have a lot of internet bandwidth! ”

Speaking of this, Lin Xuan paused slightly, and then said the reason why he said this:

"As we all know, although my Great Xia is known for its vast land and abundant resources, its population is mainly concentrated in the eastern region, and the population is also very dense.

When there are more people, the average distribution of resources to a single bandwidth will naturally decrease.

In order to reduce the pressure on bandwidth, we have even limited the upload of bandwidth, which is the only case in the world.

There is no way, we have too many people, and we have too many Internet users, so we have no choice but to do this.

If you want to increase the bandwidth according to the previous method, you can only lay optical fiber honestly, and there is no shortcut.

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

The world's most advanced silicon photonic communication chip has been manufactured, so we can cram ultra-long-range wireless laser communication devices anywhere in the 800-meter-high pole.

You can imagine that in the form of arranging a wireless laser communication device every half meter in these 800 meters, how many wireless laser communication devices can be plugged into the 800-meter-high wireless optical communication high pole?

They are cheaper to build than if they had to hire a large number of workers to dig tunnels and then bury the fiber deeply. ”

Hearing Lin Xuan's words, many people at the scene were dazzled.

In this way, compared with the old method of excavating tunnels and burying optical fibers deep in a large amount of money and human and financial costs, the cost of directly through wireless optical communication technology is simply low.

After all, wireless laser communication only needs to replace a wireless laser communication facility, and the cost is simply terrifying.

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

"Mr. Lin Xuan, may I ask what is the transmission speed of this thing, and how much bandwidth can a wireless laser communication device transmit?"

Hearing this, Lin Xuan paused slightly, and then slowly spoke:

"In terms of long-distance ultra-wireless laser communication, the standards we adopt are completely different from those of civil wireless optical communication technology.

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

So at present, the processing power of a single wireless laser-grade silicon photonics chip is 100GB per second!

In order to enhance the utilization rate of space resources, our ultra-long-distance laser communication is not a single communication point, but a form of communication equipment for multiple communications at the same time.

That is, on the level of ultra-long-distance wireless laser communication facilities, we have not one but a total of 8 lasers for communication.

So at present, our single-layer ultra-long-distance wireless laser communication bandwidth is 800GB per second transmission speed! ”

Listening to Lin Xuan's words, nearly 20,000 spectators at the scene glanced at each other, I don't know whether this number is high or low? Most people are at a loss.

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

As the president of Cisco, Chambers is also very familiar with its own Internet communication products.

Although Hantang Technology's single-layer wireless facilities only have a combined bandwidth of 800GB per second, it is just a joke compared to the now mature optical fiber communication technology.

But the problem is that there is not only one such thing, and there can be many of the same communication poles.

Think about the 800-meter-high wireless optical communication card, how many can it be arranged every half meter, and then think about how much it costs to build a new high pole......

Thinking of this, Chambers couldn't help but shudder 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 hoped that Lin Xuan had not solved the fatal flaw of ultra-long-distance wireless laser communication, the fatal flaw of being afraid of being blocked and the signal would be interrupted!

If Lin Xuan really solved that fatal flaw, then this technique would no longer be a theory.

But it can really enter people's lives, and then I am afraid that the global communication market will usher in an earthquake!

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

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

In the future, this thing can not only be applied to the Internet field, but also directly applied to the mobile phone field and even the telephone field, it can be said that he is almost omnipotent!

"Mr. Lin Xuan. ”

The reporter who asked the question just now raised his hand again, seeing this, Lin Xuan groaned slightly and waved his hand, and then the on-site staff handed the microphone to the other party:

"Mr. Lin Xuan, the prospect of your wireless laser communication is very good, its construction cost is also very low, and the network speed is also very fast, which is even better than we expected.

But we are only human beings on the earth, and there are other harsh environments, such as dense fog weather, such as flying insects, birds, insects, and so on.

Although the altitude of 800 meters is a bit high, it is nothing for some insects and even birds, and when they pass by, it may cause the signal to be interrupted, so what should we do at that time? ”

Hearing this reporter's words, many people now recall their previous concerns.

Yes, this thing is wireless optical communication, and the most feared thing about this wireless optical communication technology is to be blocked.
