What is 5G? How fast is 5G? Learn about 5G in one article

Recently, the world's first 5G railway station started construction at Shanghai Hongqiao Railway Station. According to the time plan of the three major operators, 5G equipment will begin trial commercial use this year, and mobile phone manufacturers are also accelerating the launch of 5G mobile phones. In short, 5G is getting closer and closer to us. So, what exactly is 5G? Will 5G networks be popular this year? How fast is the 5G network speed, and what black technology is behind it? Focusing on these issues that many friends are concerned about, the following article will explain them to you in a simple and easy-to-understand way.

5G

1. What does 5G mean?

The so-called "5G" refers to the fifth generation of mobile communication technology, which is the next generation upgrade of the current mainstream 4G network. In professional terms such as 3G, 4G and 5G networks, G is the abbreviation of the English word "generation". Therefore, 5G means the fifth generation of mobile communication technology.

5G

As the fifth generation of mobile communication network, 5G has a theoretical transmission speed of up to 10Gb/s or even higher. Compared with the transmission speed of 4G network, it is theoretically dozens of times faster. It is also possible to download an ultra-high-definition movie within 1 second.

2. Will 5G networks become popular in 2019?

Although 5G is getting closer and closer to us, it is still in its early stages and will take some time to become widely popularized. According to the plan, 5G equipment will begin trial commercial use in the second half of 2019, and most of the trial commercial equipment will be mobile phones.

5G will not be put into large-scale commercial use until 2020. The three major operators plan to fully launch 5G commercial use, and 5G Internet of Vehicles applications will be realized under some manufacturers.

Since the second half of 2019 is only the trial commercial stage, the price of 5G mobile phones is expected to be higher. In addition, the 5G network coverage area is limited, and the initial network fee may be high. Therefore, if you want to experience 5G affordably, it is recommended to wait until 2020.

3. How fast will 5G network speed be in actual use?

Ultimately, what everyone is most concerned about is how fast the 5G network speed is. In theory, the peak speed and speed of the 5G network are as follows:

• 5G network theoretical peak rate: 10Gb/s
• 5G network rate offline value: at least 100Mb/s

The peak and trough values ​​of 5G network speed differ by 100 times. What is going on?

In other words, although it is difficult for 5G to reach its theoretical peak speed, it is completely sufficient for daily life. For example, downloading a 1GB movie can be completed in less than 10 seconds.

4. 5G network speed is fast, what are the black technologies behind it?

1. Black technology 1: millimeter wave

2. Black technology 2: micro base station

3. Black Technology 3: Beamforming

4. Black Technology 4: D2D

The black technology behind 5G is quite complicated. The picture below can give you an easy-to-understand understanding.

5. In addition to fast Internet access, what else can 5G do?

1. Improve the safety of autonomous driving and build a "connected vehicle"

2. Home appliances and furniture realize intelligent interconnection

3. Virtual reality, augmented reality, etc. are widely used

4. Make AI smarter

What else can 5G do?

The above is the introduction to 5G. From the experience point of view, the highlight of 5G network is the significant increase in speed, which can effectively promote the development of the Internet of Things, Internet of Vehicles, artificial intelligence and other scenarios. For consumers, if they want to experience 5G, they first need to buy a mobile phone that supports 5G network. In addition, you need to have 5G network signal coverage in your location and operator. What other questions do you have about 5G or what else do you want to share with everyone?
