5G brings more than just internet speed. What does 5G really mean?

What does 5G mean? It means faster upload and download speeds, cool VR entertainment experience, urban IoT, driverless cars, telemedicine... 5G is not just about internet speed, it can revolutionize the times!

Faster upload and download speeds

The most obvious and direct impact of the advent of the 5G era is the increase in network data upload and download speeds. The peak rate of 5G networks can reach 20Gbps, which means that the next 8GB movie only needs 6 seconds, while on a 4G network, it takes seven to eight minutes.

Cool VR entertainment experience

VR is actually a concept that has been around for a long time. Through VR, we can get a 360-degree virtual reality experience, as if we are in the real world. It is very suitable for the movie and game industries. The reason why it was not popular before was that the network bandwidth was insufficient and the network latency was high, resulting in video freezes and poor picture quality. The arrival of 5G solves these problems. High bandwidth allows and low latency, ensuring the transmission of large amounts of data.

Urban IoT

The interconnection of all things is one of the ultimate goals of the Internet of Things in the context of the artificial intelligence era. However, the current Internet of Things has not been fully developed, and the Internet of Things currently implemented is still relatively low-end. One of the cruxes is that the wireless network bandwidth and latency do not meet the standards. The 5G era makes massive Internet of Things possible.

For example, infrastructure IoT: Infrastructure will be connected by mobile broadband, such as street lights, water meters, and trash cans. City managers can accurately know the status of each infrastructure, such as which street light is broken, which section of the water pipe is leaking, and which trash can is full. This is of great significance for improving the operating efficiency of the city and facilitating people's lives.

unmanned

To realize autonomous driving, vehicles need to have the three functions of "environmental perception, analysis and decision-making, and action control" like humans. And each function needs to be broken down into every tiny link to achieve the ultimate safety and reliability.

For example: ① The detection accuracy, distance, and supplementary functions of the sensor in the face of severe weather; ② Comprehensive input and timely update of road conditions by high-precision maps; ③ The upgrade and accuracy of machine vision (the ability to recognize pictures, numbers, traffic lights and even blurred road signs, and empirical judgment in the absence of certain information); ④ The timeliness and always-online processing of big data; ⑤ Reduction of secondary destructiveness of car windows and seats in the car when an accident occurs, etc.

The upgrade of communication technology and the implementation of 5G networks are necessary means for autonomous driving to achieve ultimate safety and 99.999% reliability.

The 5G era defines three major scenarios

In summary, the 5G era defines the following three application scenarios:

1. eMBB: Enhanced Mobile Broadband, as the name suggests, is aimed at high-traffic mobile broadband services;
2. URLLC: ultra-high reliability and ultra-low latency communication, such as autonomous driving (3G response is 500ms, 4G is 50ms, and 5G requires 0.5ms);
3. mMTC: Massively Machine Type Communications (MMTC), targeting large-scale IoT services;

5G brings faster speed, lower power consumption, shorter latency, stronger stability, and can support more users. 5G data is shown in the following figure:

Seeing this, I believe everyone has understood that the reason why 5G is so popular and has caused all major camps to fight each other is that 5G network brings not only changes in network speed, but more importantly, subversion of lifestyle. It is no exaggeration to say that whoever masters 5G will master the next era.
