What is 5G Network?

Unlike 3G and 4G networks, 5G has one and only one global communication standard, which is defined by many countries and companies around the world. In addition, 5G defines three features with the ability to support different application scenarios in the future, namely, high reliability and low latency of uRLLC, eMBB enhanced mobile bandwidth, and mMTC large-scale machine communication.

EMBB enhanced mobile bandwidth

This feature is the most easy for people to realize. Many traditional media and we-media bloggers are making relevant video explanations. For example, 1GB video can be downloaded in a few seconds, while 5G mobile phone can download dozens of apps in a single second. For the high-density crowd areas mentioned above, 5G can also better provide bandwidth for everyone.

Of course, there are many more application scenarios, such as the VR projects we saw in the store. Most of them are carried out by sitting still or moving slowly, and it is troublesome to put the transmission line on the eyes. Because 5G network has the characteristics of large bandwidth, it can realize the wireless of VR eyes, and deliver the whole image rendering ability and computing power to the remote processing, further reduce the computing power and cost of VR eyes, so as to better popularize.

MMTC high reliability low latency

Low latency is necessary for many application scenarios, especially for autonomous driving and intelligent healthcare. We all know that safety is the core of automatic driving. Although 95% safety can be achieved at the present stage, it is still far from the commercial requirements. At least 99.999% safety factor and even higher should be achieved. For example, when a driverless car is on the road, the system will monitor the road conditions in real time, and when it goes to an anomaly, it needs to make an emergency response in time. The delay is also required to be a few millimeters. If the delay is in seconds, it may cause an accident before it can respond.

Another industry that has attracted more attention is intelligent medical industry. In the future, people need to control the movement of scalpel with very low delay when conducting telemedicine. For example, the thickness of blood vessels is 0.2ms, and the scalpel will move around 0.5cm due to the delay in 4G network, which is very dangerous. The delay of 5G network is about 5ms, and the distance of the scalpel caused by the delay is about 0.025mm, which will greatly improve the safety of surgery.

MMTC large-scale machine communication

I believe many friends have already experienced this feature. Young people who like to walk in the forefront of The Times and technology and digital enthusiasts have tried a variety of smart devices, such as smart home, smart wear, etc., which requires 5G network with high capacity. The core of 4G network is to connect people to each other. The number of connections in the world is 100 million. Each person may need a phone, computer or tablet to connect to the network.

However, with the development of the Internet of things (IoT), the future 5G network needs to connect different things and things, things and people. The world needs to carry up to a quadrillion connections.
