Technological Empire Starts From Shanzhai System Chapter 614

5G has many advantages over 4G, just like 4G+ has huge advantages over 3G and 2G!

The birth of 5G will also make a huge contribution to social industrial upgrading and economic development. "

Hearing Lin Xuan's words, people nodded slightly.

People have known this for a long time. After all, the publicity and experts' remarks for more than half a year are not for nothing.

So they also recognize that the birth of new technical standards will make great contributions to industrial upgrading and economic development.

Although the role of 4G+ in promoting industrial upgrading and economic development does not seem to be so obvious compared to 3G.

After all, with wireless optical communication technology to improve network speed, the effect of 4G+ mobile communication technology on industrial upgrading and economic development is not so obvious.

I just don't know whether the birth of this 5G mobile communication technology can achieve things that 4G+ mobile communication technology can't do.

"First of all, let me introduce the first product, which is the selling point of 5G.

This selling point is the super speed and delay of 5G!

The fastest network speed in the current mobile communication field is wireless optical communication technology, which can transmit 10GB of network speed in one second, relying on the almost lossless transmission of optical signals.

But the disadvantage is that in the outdoor environment, there will be interference from external light sources, so although the network speed of wireless optical communication technology is very strong, it is not suitable for all scenarios.

In order to solve this problem, all our mobile phones use wireless optical communication technology and WIPI wireless LAN to form a complementary technology.

So when the wireless optical communication technology can be used indoors or outdoors, the wireless optical communication technology will be used first. When the wireless optical signal is interrupted or the wireless optical communication technology cannot be used, the weaker WIPI wireless LAN will be used.

Although the 5G network speed we are going to launch now cannot achieve the terrifying network speed of 10GB per second of wireless optical communication technology, after all, radio signals are too susceptible to interference, and it cannot achieve the nearly lossless transmission of signals like wireless optical communication technology.

But it is a revolutionary innovation for 4G+ mobile communication technology and even 3G mobile communication technology. Since then, 4G+ mobile communication technology can be swept into the history heap immediately. "

Hearing Lin Xuan's long speech, people's eyes became more and more curious.

Although Lin Xuan has already said that the network speed of 5G cannot achieve the network speed of 10GB per second like that of wireless optical communication technology, it is definitely better than 4G+ mobile communication technology, but I don't know how strong it is.

At this time, a projection screen of a mobile phone appeared on the projection screen behind him. Seeing this, people immediately looked at the projection screen above with bated breath.

"The mobile phone in my hand is the Hantang S5 that will be released soon. First, let's experience how strong the network speed of 5G plus mobile communication technology is."

After Lin Xuan finished speaking, Lin Xuan also controlled the mobile phone in his hand, and clicked on a network speed test software developed by Hantang Technology.

This network speed test software mainly tests the web browsing speed, game browsing speed, Internet speed, signal transmission connected to the 5G base station, and the delay speed test between the mobile phone and the 5G base station.

Among them, the speed of Internet access is naturally the real speed of the Internet. For example, the real speed of 100M broadband is 12M per second, although most of the software in your actual use must not use such a fast speed.

But it represents the upper limit of the Internet speed for personal use, and it means that sometimes such a speed can indeed be achieved if there is suitable software.

For example, when you download something, as long as the downloading party gives you bandwidth resources, it must be able to achieve such a download speed.

The same is true for connecting to 5G base stations. Usually, the speed of connecting to 5G base stations is quite different from the real Internet speed.

For example, 5G in the future claims to support the use of 1Gbps network speed, that is, it can download 1024MB per second, but in reality it is only about 70M per second, and a few areas can use 120MB per second.

So there is a huge difference between the actual network speed that can be used and the network speed of the communication between the mobile phone and the base station, and the network speed of the two cannot be concluded.

The reason why this is the case is that the speed of the Internet is determined by the Internet as a whole.

No matter how fast your local internet speed is, but the overall speed of other networks can't keep up, what's the use of how fast your local mutual communication speed is?

In fact, the 5G network speed of the former Shiguowei company has not yet reached the upper limit, and its Internet access speed has been greatly improved, so the speed between the mobile phone and the 5G communication tower will be higher than the actual network bandwidth speed.

Usually, the peak theoretical transmission speed of 5G mobile communication can reach 20Gbp, or 2.5GB per second, which is only higher than the 10GB per second of wireless optical communication technology.

But this is just a theory. In the real environment, because the external 5G signal interferes with the wireless high-frequency electrical signal that is born every moment on the earth, it must not be able to achieve the theoretical speed.

Internet netizens also know this, which is why 5G mobile communication technology will be the focus of attention, although 5G mobile communication technology is not as fast as wireless optical communication technology.

But the problem is that 5G mobile communication technology does not have the disadvantages of wireless optical communication technology. It can penetrate objects, is not afraid of the interference of strong light from the outside, and can use 5G mobile communication technology in the outside world without hindrance.

So compared with wireless optical communication technology, 5G is more suitable for the present and the future. I just don't know what is the 5G speed of Hantang Technology at this time? Can it achieve the theoretical speed of 2.5GB per second?

In this way, in the sight of people's curiosity, the test software started to start, and people also stared at the projection screen above with bated breath.

"My God, this delay is horrible."

"How can the internet speed be so fast?"

At the beginning, the first thing to test is the connection speed of the webpage. There are many popular webpages in the opened webpages, such as Penguin Portal, Molang Portal, and Yiyi Game webpage and so on.

Among these pages, their latency is so low that it is beyond people's imagination!

"The average delay is 3ms to 5ms, which is horrible. Is this the world I know?"

Among the many guests, a young man with the online name Ceramic Pot opened his eyes wide, with disbelief and astonishment written all over it.

Because when the speed reaches tens of milliseconds, every reduction of one millisecond is a huge leap. At this time, Hantang Technology's web browsing speed is only 3~5ms, which is really surprising.

It is necessary to know that the delay of using wireless optical communication technology is very low, but even if it is such a delay, it generally fluctuates between 15 and 23.

The reason why there is such a large fluctuation is that there are flying birds passing through the ultrlong-distance wireless optical communication tower and the signal is interrupted, so it takes 1ma to 2ms to switch to the signal.

The distance is too far, there must be signal interruption between more than one communication tower, so the time will fluctuate between 15ms~23ms.

The new book "Great Country Science and Technology Begins with Copycat System" has 68,000 words, and it is ready to be killed.

Now the new book ranks 31st, please vote for the monthly ticket and reward, let's push the new book to the 20th, thank you.
