Daguo Technology started from the Shanzhai system

And this has also made CEOs of other communications industries around the world, such as Noah, Ericsson, Draftcom, Cisco...

The CEOs of companies including Corning, Prysmian, Furukawa, Sumitomo and other giants in the optical fiber and cable communication equipment industry all looked very ugly.

As for why the CEOs of the giants in the optical fiber and cable industry have ugly faces, the reason is that as professionals they naturally know that they want to rely on 4G mobile communication technology to achieve such high network speeds.

It is not enough to rely solely on 4G mobile communication technology. This 4G mobile communication technology only faces the terminal market of the market.

It is only equivalent to a person's hands and feet, and what determines whether a person's hands and feet are strong or not is a person's body.

Otherwise, no matter how strong your arms and legs are, but your body is skinny, your weak body will limit the strength of your arms.

Judging from the tests at this time, Sugon Technology actually mastered not only the hands and feet of 4G mobile communication technology terminals, but also simultaneously developed the body, that is, the Internet communication technology of ultra-high-speed optical fiber and optical cables.

And considering that this time it is not just the release of 4G mobile communication technology, but also the release of 5G mobile communication technology, in order to unleash the potential of 5G mobile communication technology.

Next, you can imagine how terrifying the Internet communication technology of Sugon Technology's fiber optic cable has reached!

Thinking of this, the CEOs of the global optical fiber and cable Internet communications industry felt chills running down their backs, feeling like the sky was about to fall!

In this regard, Lin Chen at this time did not care how sad the CEOs of other fiber optic cable Internet communications or mobile communications fields around the world felt.

After he introduced the functions and performance of 4G mobile communication technology, Lin Chen showed a mysterious smile and said:

“Well, the purpose of developing 4G mobile communication technology is, after all, just to supplement the shortcomings of 5G mobile communication technology.

In the future, if the construction cost of our 5G mobile communication technology can be significantly reduced, or if the next generation 6G mobile communication technology achieves great development, then 4G mobile communication technology will eventually be eliminated.

Next, let us enter the introduction of the main course. After all, compared to 5G mobile communication technology, 4G mobile communication technology is only an infant-level technology.

The birth of 4G mobile communication technology is not enough to change the world. Only 5G mobile communication technology can truly change the world! "

Hearing Lin Chen's words, people were stunned at first, subconsciously feeling that Lin Chen was exaggerating, and he actually praised 5G mobile communication technology so much.

Moreover, 5G mobile communication technology is called changing the world. Is this a bit exaggerated?

After all, no matter how powerful the 5G mobile communication technology is, isn't it just a mobile communication technology? No matter how high the network speed is, can it still fly into the sky?

Facing the disbelieving audience and reporters, Lin Chen just smiled and did not laugh at them for their short-sightedness.

After all, 5G mobile communication technology seems to have only been upgraded by one generation on the surface, so it should not be able to win such an honor.

But who could have imagined how huge and exaggerated the increase in network speed 5G would be, to the point where it would eventually be able to support the implementation of many fantasy-level black technologies?

So Lin Chen waved his hand gently, and the projection screen behind him suddenly changed. In an instant, the structure diagram of 5G mobile communication technology appeared on the projection screen.

This structural diagram is mainly a densely packed micro base station, and then these micro base stations are arranged in photos of train stations, parks, squares and street scenes.

At the same time, Lin Chen’s words also came out:

“I said before that the construction cost of 5G mobile communication technology is relatively high, and the reason is as everyone has seen. Its biggest feature is that it needs to be calculated based on the real environment, and then the staff will install the micro base station equipment.

Compared with 4G mobile communication technology, which only needs to build a large communication tower to cover a large area, how can the construction cost of 5G not be high? "

When Lin Chen finished speaking, the picture on the projection screen behind him also changed instantly, turning into a picture in the Sub-6GHz (centimeter wave) frequency band.

“As shown in the figure, our Dawn 5G mobile communication technology uses the Sub-6GHz frequency band in the centimeter wave range.

The radio waves in this frequency band have a wavelength range between 450MHz and 6GHz, which belongs to the low-to-medium frequency band and is also the golden frequency band for 5G networks. "

When Lin Chen said this, he paused slightly, and then continued to introduce:

“Seeing this, many people in the communications industry or those who understand cutting-edge technology will be curious about why we don’t use millimeter waves with higher frequency bands, but choose centimeter waves.

The reason is that millimeter waves are fast, but we have to consider whether it is really practical, whether the construction cost is acceptable, and many other real-world considerations.

And the biggest drawback of millimeter wave is that its communication distance is extremely short and the construction cost is extremely high. The number of micro base stations is more than five times that of centimeter wave, and the electricity bill is naturally higher.

And the most serious thing is that the penetration of millimeter waves is very poor. 5G mobile phones using millimeter wave technology can block the signal by almost anything, including phone booths, glass, trees and rain.

It can be said that as long as there is obstruction between the base station and the mobile phone, the 5G network may fall back to the 4G state!

And this shortcoming is naturally impossible to accept. You can imagine how bad your mood will be if you are playing a game with high bandwidth requirements and suddenly cannot play it, or a super-clear video suddenly stops and freezes...

In addition, the biggest thing about 5G mobile communication technology is that it can be applied to industry and automatic cars. If it rains and rain blocks the 5G network, what should the cars that are driving themselves do?

So we use the Sub-6GHz (centimeter wave) frequency band. There is a reason why this frequency band is called the golden frequency band of 5G.

First of all, it has strong penetration ability, longer transmission band, more stable connection, fewer micro base stations to be invested, and lower electricity maintenance costs.

It can be said that our choice of the Sub-6GHz (centimeter wave) frequency band is a choice of the times and an inevitable choice! "

Speaking of this, Lin Chen waved his hand gently when people seemed to understand, and then the projection screen behind him turned into an introduction screen of 5G mobile communication technology.

First of all, the first technology that appears in front of people is beamforming technology. Accompanying this is a picture of the principle of beamforming technology.

“The first technology we want to introduce first is beamforming technology. The highlight of this technology is that it can strengthen the signal in one direction.

Traditional signal base stations are like light bulbs, emitting their signals in all directions, which was nothing in the era before 4G or even 3G.

However, because 5G mobile communication technology uses the Sub-6GHz (centimeter wave) frequency band, the communication range is naturally not comparable to the communication range of 4G or even 3G mobile communication technology.

In order to solve the problem of short communication distance, we have developed beamforming technology, through which the chip can automatically control the signal in a certain direction to strengthen it.

Ultimately, the communication distance is enhanced and the signal stability is improved in disguise, allowing consumers to experience a stable and high-speed 5G mobile network. "(End of chapter)
