5G in today’s society is no longer the future tense but the ongoing tense.
## Three major characteristics of 5G network: (Recommended learning: PHP video tutorial)
Ultra-high speed, it is not just as simple as downloading 30 movies in one second, VR and AR cloud technology will be seamlessly connected with life;
Ultra-reliable and low latency , making unmanned driving and remote surgery no longer far away;
A large number of terminal networks will form a broader and open Internet of Things, making smart homes and smart cities possible.
In terms of ultra-high speed, the peak downlink rate under the 5G network can reach 20Gbit/s, and the uplink rate can reach 10Gbit/s. What is the concept? Just compare it directly with the 4G network and you will know. At the peak rate of the 4G network, the downlink is 1Gbit/s. In other words, the speed of 5G is 20 times that of 4G, and the change in user experience it brings is not simply a slightly faster speed.
In terms of ultra-reliable reliability, in fact, we often hear about the application scenario of 5G - automatic driverless driving. Why is it automatic driverless driving? On the one hand, autonomous driving requires extremely low latency requirements. Just like when we find a situation while driving and have to step on the brakes, the reaction speed of ordinary people is 0.4 seconds, which is between 400 milliseconds, while in 5G, it only takes 1 millisecond. reacted. Therefore, the ultra-low latency feature of 5G can be used in many scenarios.
Continuing to use autonomous driving, they can pass through intersections automatically, quickly, and alternately. Why? To put it simply, it is the networking between cars. In addition to the ultra-high speed and ultra-low latency attribute requirements mentioned above, there is also an extremely large number of terminal networks. Under the 5G network, its standard is that 1 million devices can be linked per square kilometer. Thinking about this digital density, all cars on the same network can naturally make autonomous driving a more unique experience. At the same time, this is also an application scenario of the Internet of Things.
