The significance of 5G

5G is getting closer and closer to us. Although we often hear the significance of 5G, many people have a question: 4G network speed is enough, why do we need 5G?


5G is not simply a speed increase. In short, the advantages of 5G are threefold:


The first is high speed: in actual applications, the speed of 5G networks is more than 10 times that of 4G networks;


The second is low latency: the latency of 5G networks is about tens of milliseconds, which is faster than human response;


The third is the wide connection: With the emergence of 5G networks, in conjunction with other technologies, space will be severely compressed in the sense of data, and it is likely that a new set of interconnections will emerge.


5G rate

5G application scenarios In addition to 4G scenarios, under the blessing of high network speeds and low latency, 5G can also be widely used in AR / VR panoramic live broadcast, holographic projection, drone operations, telemedicine, driverless, In more scenarios such as the Industrial Internet. 5G uses massive MIMO (massive MIMO) technology to make the network speed a huge improvement over 4G, the rate has reached more than 10 times 4G. In the field of the Internet of Things, by reducing the signaling overhead to make the terminal more power-saving, non-orthogonal multiple-access technology is used to support more terminal access, thereby realizing the dream of Internet of Everything.


With the advancement of 5G, there may be breakthrough developments in the following areas:


AR / VR

Virtual reality and augmented reality technologies have existed and developed for decades, but they have been unable to give people a satisfactory experience due to network speed and latency. And 5G is likely to improve the immersion of virtual reality by increasing the network speed by more than 10 times compared to 4G. Once the network speed bottleneck is broken, VR games, VR live broadcast and other related fields of virtual reality can become reality. Under the blessing of VR, whether it is a game or a sports event live broadcast, compared with the traditional screen, it is a reduction of dimension.


Telemedicine

Because of geographical and resource allocation, high-quality medical resources are often limited to a few places, while other remote cities suffer from a lack of excellent attending physicians. Once surgery is required, they often need to travel long distances, which not only delays treatment but may also aggravate the condition. With the advent of the 5G era, telemedicine is becoming more widespread.


The problems are ever-changing during the operation. Only the high speed and low latency of 5G can ensure that the medical treatment can reasonably respond to emergencies. With 5G technology, doctors can operate the equipment more accurately and conveniently remotely, and obtain surgical information in real time in order to make more accurate judgments.


Internet of things

The number of 5G 1 million / square kilometers access has greatly improved the efficiency of the Internet of Things, which can meet the ubiquitous connection requirements of the Internet of Things, so that all Internet of Things devices can be connected to the network, thereby achieving the interconnection of all things. And ultra-reliable, low-latency connections. Provide users with end-to-end millisecond-level delay and nearly 100% service reliability guarantee, and then provide realistic guarantee for unmanned driving, industrial control and other operations that require high precision.


The changes brought by 5G are not just the obvious products of mobile phones. In other areas beyond the above, such as AI, big data, cloud computing, edge computing technology, etc., there is room for 5G development. Maybe in the near future, the scenes in the once science fiction will become reality one by one and come to us.
