This article mainly introduces "what are the three advantages of 5g". In daily operation, I believe many people have doubts about which three advantages of 5g. The editor consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the question of "what are the three advantages of 5g?" Next, please follow the editor to study!

The three advantages are: 1, high speed; 5G speed can reach 100 times that of 4G, achieving the peak speed of 10Gb/ seconds. 2. Low delay; the empty port delay of 5G can be as low as 1 millisecond, which is only 1/10 of that of 4G. 3. Large connections; 5G can have 1 million connections per square kilometer, and the user capacity can be greatly increased compared with 4G.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

4G changes life, 5G changes society. 5G, a society of the Internet of everything is about to shine into reality. What is 5G?

It is the next generation (fifth generation) mobile communication, which can provide faster upload and download speed, wider coverage, and more and more stable connections.

5G is the main direction of the development of the new generation mobile communication technology and an important part of the new generation information infrastructure in the future. Compared with 4G, 5G has the technical characteristics of "ultra-high speed, ultra-low latency and super connection", which will not only further enhance the network experience of users and bring faster transmission speed for mobile terminals, but also meet the application needs of the Internet of everything in the future. give the ability to connect everything online.

At the end of 2018, the 5G frequency distribution of the three major domestic operators finally settled. China Telecom and China Unicom each received 100m (megabit) frequencies in the 3.5GHz (gigahertz) band, while China Mobile received a total of 260m frequencies in the 2.6GHz and 4.9GHz bands. According to the frequency license, the three major operators can carry out 5G tests nationwide. It is almost certain that 2019 will be China's "5G first year".

Why do we need 5G?

The world is becoming mobile, and we are consuming more data every year, especially the increasing popularity and increase of video and music streaming. The frequency band is becoming more and more crowded, leading to service disruptions, especially when many people in the same area try to access online mobile services at the same time. From mobile phones to device sensors, from cameras to smart streetlights, 5G is better at handling a large number of devices.

What are the advantages of 5G?

Compared with 4G, 5G has the characteristics of "higher network speed, low delay, high reliability and low power mass connection".

In terms of ultra-high speed, the 5G speed can be up to 100 times that of 4G, achieving the peak speed of 10Gb/ seconds, being able to watch 4K and 8K HD videos fluently on your mobile phone, rapidly playing 360-degree panoramic VR games, and so on.

In terms of ultra-low delay, the empty port delay of 5G can be as low as 1 millisecond, which is only 1/10 of that of 4G, which is much higher than the stress response of human body, and can be widely used in the field of automatic control.

In terms of super-large connections, 5G can have 1 million connections per square kilometer, and the user capacity can be greatly increased compared with 4G. In addition to the connection of mobile terminals, it can also be widely used in the Internet of things.

Application scenarios of 5G

In the impression of the average user, 5G may just mean "higher Internet speed". But in fact, in addition to "mobile broadband enhancement" (ultra-high speed), 5G application scenarios also include "low-power massive connections" and "low latency and high reliability".

"Mobile Broadband Enhancement" can be further subdivided into two scenarios: "wide area continuous coverage" and "high capacity hotspots". The characteristics of the former are reflected in the breadth of coverage, with the goal of ensuring user mobility and business continuity, and providing users with high-speed business experience anytime, anywhere. The latter reflects the "quality". In large-scale assembly scenarios such as sports venues or concerts, users are provided with extremely high data transmission rates to meet the extremely high traffic density requirements. Popularly speaking, you can surf the Internet anywhere. At the same time, not only can surf the Internet, but also very fast, and high fidelity.

"low-power mass connection" is mainly aimed at smart cities, environmental monitoring and other application scenarios aimed at sensing and data acquisition. It has the characteristics of small data packet, low power consumption, massive connection and so on. It not only has the ability to support hundreds of billions of connections and meets the connection density index of 1 million / square kilometers, but also ensures the ultra-low power consumption and ultra-low cost of the terminal. It is precisely because of the existence of this scene that the process of the Internet of things will once again accelerate, and the so-called "Internet of everything" will eventually be reflected into reality. And the phrase that is often mentioned recently, "4G changes life, 5G changes society".

"low delay and high reliability" is mainly oriented to the special application needs of vertical industries such as vehicle networking and industrial control. Such applications have extremely high requirements for latency and reliability, and need to provide users with millisecond end-to-end delay and nearly 100% business reliability. Specifically, in this scenario, 5G can achieve a delay of less than 10 milliseconds, which means that automatic brake control is almost the same as human braking response time. In addition, 5G can be calculated at the edge of the base station, which means that autopilot data can be processed on the network closest to the car without having to upload it to a relatively distant block computer room. This will also shorten the response time of autopilot.

In the above three application scenarios, the corresponding 5G network design is different. Through the BBU end function split, the core network part sinking and other means, through the "slicing" means to split and refine the network resources, so as to achieve a flexible response to the needs of the scene. In other words, there is no omnipotent network, and the same structure can meet the demands of three different scenarios at the same time. In implementation, 5G divides the physical network into N logical networks according to logic, while different logical networks serve different scenarios, which is like achieving the effect of "Swiss Army knife" multi-function network.

At this point, the study of "what are the three advantages of 5g" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
