5G has many advantages over 4G, just as 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 propaganda and the remarks of experts for most of the year have not been done in vain.

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

Although 4G+, compared with 3G, does not seem to play a very obvious role in promoting industrial upgrading and economic development.

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

I just don't know if the birth of 5G mobile communication technology can achieve something 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 latency of 5G!

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

However, the disadvantage is that there will be interference from external light sources in the outdoor environment, 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 of our mobile phones use wireless optical communication technology in conjunction with WIPI wireless LAN to form a complementary technology.

Therefore, when wireless optical communication technology can be used indoors or outdoors, wireless optical communication technology will be preferred, and when wireless optical communication technology is interrupted or wireless optical communication technology cannot be used, the weaker WIPI wireless area network 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 easy to interfere with and cannot do the near-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, and from then on, 4G + mobile communication technology can be swept into the pile of history. ”

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

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

At this time, the projection screen of a mobile phone appeared in the projection screen behind him, and 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 next, first of all, let's experience how strong the network speed of 5G plus mobile communication technology is."

As Lin Xuan's words were finished, 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 web browsing speed, game browsing speed, Internet speed, signal transmission connected to 5G base station, and latency speed test between mobile phone and 5G base station.

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

But it represents the upper limit of the speed of the Internet for personal use, and it means that it is possible to achieve such speeds with the right software sometimes.

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

The same is true for connecting 5G base stations, which are usually connected to 5G base stations and have a big difference between the speed of connecting to 5G base stations and the real Internet speed.

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

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

This is the case because the speed of the internet is determined by the Internet as a whole.

No matter how fast your local Internet speed is, but the other Internet speeds can't keep up with the overall speed, what is the use of your local Internet speed for communicating with each other?

In the past, the company's 5G network speed has not yet reached the upper limit, and its Internet 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.

In general, the peak theoretical transmission speed of 5G mobile communication can reach 20Gbp, which is 2.5 GB per second, which is only 10 GB per second compared to wireless optical communication technology.

But this is only a theory, and the real environment is definitely not able to achieve the theoretical speed because of the interference between the external 5G signal and the wireless high-frequency electrical signal that is born on the earth all the time.

Internet users also know that this is also the reason why 5G mobile communication technology will be focused on, 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 shortcomings of wireless optical communication technology, it can penetrate objects, is not afraid of the intervention of strong light from the outside world, and can use 5G mobile communication technology in the outside world without hindrance.

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

In this way, in the eyes of people's curiosity, the test software began to start, and people stared at the projection screen on it with bated breath.

"Oh my God, this delay is horrible."

"How the hell is this done, how can the internet be so fast?"

At the beginning, the first test was the web page connection speed, and there are many popular web pages in the web pages opened above, such as penguin portal, a certain wave portal, a certain easy game web page, and so on.

On these pages, their latency is incredibly low!

"The average latency of 3ms to 5ms is terrifying, is this sure that the world is my perception?"

Among the many guests, a young man with the online name Ceramic Pot had wide eyes, and it was full of disbelief and astonishment.

Because when the speed reaches more than ten tens of ms, every millisecond is a huge leap, and the speed of Hantang Technology's browsing of the web is only 3~5ms, which is really surprising.

It is important to know that the latency of wireless optical communication technology is very low, but even if it does, it generally fluctuates between 15~23.

The reason why there is such a big fluctuation is because there are birds passing through the ultra-long-distance wireless optical communication tower, which causes the signal to be interrupted, so it takes 1 mA to 2ms to switch to the signal.

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