It is understood that the advantages of 5G compared to 4G are the following:
1, ueMBB enhanced mobile bandwidth
For example, a 1GB video download is completed in more than a dozen seconds, for example, the 5G cell phone in a flash to download dozens of apps and software, and for the high-density Crowd places such as concerts, gymnasiums, shopping malls, etc. 5G is also better able to provide broadband for everyone.
2. umMTC is highly reliable and low-latency
Especially in the field of autonomous driving (road detection) and intelligent healthcare (telemedicine), low-latency is just what is needed, and 5G will be able to improve the overall security (millisecond response).
3, umMTC large-scale machine communication
In the 4G era, the core of the network is to connect people to people, the number of connections carried globally is the level of hundreds of millions of people, each person may need to connect to the network of cell phones, computers, tablets, but this number is controllable.
But the development trend of the Internet of Things, 5G network needs to connect different things and things, things and people, then the connection may be trillion level, which requires the network to have high capacity characteristics.
For example, the possibility of intelligent hardware networking, today, although we have a WIFI network in every home, but the bandwidth limitations, playing games, watching videos, and then open a network TV, a family of each person with a service bandwidth is not enough, the 5G network under the bandwidth service increases, a cell phone number corresponds to a user, multiple intelligent hardware binding A cell phone number, all devices can be realized networking. Well, Xiaomi's current Mijia ecosystem can also be done. But the 5G environment is an advanced version of the application, that is, the information can be synchronized with each other in real time, the tablet open video can be switched to the TV or cell phone in real time, the cell phone desktop can be controlled directly on the computer in real time, so that data synchronization can only be achieved in the 5G environment.
For example, the realization of the Internet of cars and cloud applications, the future of the car is a major direction of the new energy industry, in another 10 years, electric cars will fully replace the fuel car . In-vehicle devices and in-vehicle systems are the next important entrance to mobile, for example, driving commuters, every day on the highway blocked for 1 hour, can not do anything, can only rely on the in-vehicle system, you say this market has a high potential for users ...... There is also the issue of cloud applications, are saying that the tablet can not replace the laptop, mainly because the computing power can not reach the desktop level, but if the 5G speed is fast enough, the application is running on a cloud server, the tablet PC receives data in real time, is not it possible to use more professional applications? The office scene is also naturally subverted.
Transmission speed is a bottom thing, the core of the main or grow out of the service, like 10 years ago, you can foresee that today you can take the phone to do live broadcast?
