Is 5G coming too fast? No, it’s just the communication technology that is being upgraded.

In this era, people’s understanding of happiness is actually very simple: the mobile phone is fully charged and the signal is full.

For modern people, mobile phones are life.

In the past, you had to carry money when you went out, but now I guess you can’t find any cash even if you search your body.

Buying things can be easily done with just a simple sentence like "scan where" or "you scan me or I scan you".

But do you know that today's convenient life did not come out of thin air?

In 1876, an American entrepreneur named Alexander Graham Bell invented the telephone.

From then on, people could contact anyone at any time, no matter how far away they were. People said goodbye to the era when communication was basically based on shouting.

However, not everyone is sitting in front of the phone all the time, so mobile phones came into being, which are the handheld phones we are familiar with.

From the big brother to today's touch screen, mobile phones have more and more functions and are becoming thinner and lighter. All of this is inseparable from the development of communication technology.

Simply put, communication technology is the transmission of information from one place to another through electromagnetic waves.

5G, which is very popular now, stands for the fifth generation mobile communication technology.

You may be curious, how come we have reached the fifth generation so quickly? What happened to the previous generations?

The first generation of mobile communication technology, or 1G, was only capable of making phone calls, and the call quality was very poor.

The second generation of mobile communication technology (2G) had improved transmission speed and call quality, but its Internet speed was very slow, so it was quickly replaced by the powerful 3G.

The third generation of mobile communication technology (3G) can transmit general video images and data. It can be said that without the foundation laid by 3G technology, there would be no 4G today.

The fourth generation of mobile communication technology (4G) is even more powerful. It can transmit high-quality videos and pictures. Compared with 3G, 4G is faster and clearer. Do you still remember that when you used 3G to upload pictures, the speed was slow and the pictures were blurry; when you watched a video, the buffering circle would take a long time to play. All of this has become history in the 4G era.

4G has solved most of the network and communication needs in our lives, so what new features does the fifth-generation mobile communication technology (5G) have?

Of course the answer is yes.

The first feature of 5G is that the signal transmission speed is very fast.

Let's use eating as an example. 3G is eating rice one grain at a time, 4G is eating it one spoonful at a time, and 5G is eating it one bowl at a time. In the 5G era, it is estimated that the download progress bar will become history.

The second feature of 5G is low latency.

A latency of about one millisecond can meet many scenarios with strict requirements on response time, such as telemedicine, autonomous driving, and virtual reality technology.
