Since the birth of the mobile phone, it has experienced the evolution of four generations of communication technology. Currently, the most advanced network is 4G LTE network, and some countries will take the lead in commercial 5G network next year. Mobile phone manufacturers will also launch 5G mobile phones. Most people are still relatively unfamiliar with 5G networks. So, where is the 5G network upgraded? What is the use of it?
As the fifth-generation mobile communication network, the 5G network has a peak theoretical transmission speed of tens of Gigabits per second, which is hundreds of times faster than the transmission speed of 4G networks. The entire ultra-high-definition movie can be downloaded within 1 second. . In addition to high bandwidth, 5G networks have lower latency than 4G networks, and the Ping value of 5G networks can reach only a few milliseconds.
The current 4G network speed is already very fast, so is the speed of 5G network so necessary? At present, even if the network speed is fast, but the telecom operators still charge according to the flow rate, few people will use the mobile network to download movies. So what is the use of 5G?
In fact, 5G network has surpassed the scope of mobile phone network. 5G will never be the same as the 3G transition to 4G. The intuitive feeling for consumers is the improvement of network speed. 5G is revolutionary. It is revolutionary because it is because 5G includes the Internet of Things. Since human beings entered the information society, the changes brought by the Internet have become the engine of the world economic development in the 21st century, and the 5G Internet of Things will expand the application range of the network to an unprecedented breadth. There are two types of networks in 5G networks, one is the traditional mobile phone network, and the other is the network for the Internet connection, which is the Internet of Things. The devices to be connected to the 5G network are not only mobile phones, like self-driving cars, remote Medical and other companies will use 5G networks.
As far as drone driving is concerned, no driver will never mature without a 5G network. A high-bandwidth, low-latency 5G network is essential for driverless driving. Only the bandwidth is high enough to carry thousands of roads. Cars, only with a low enough delay to ensure a timely response in the event of a dangerous situation.
Google, Baidu, Tesla, etc. are all researching unmanned or autonomous driving technology. If you study the three carefully, you will find one thing in common: these unmanned drivers are playing "single game", that is, between cars and people. There is no connection between the cars, there is no network connection, but the focus is on the sensor's identification of complex roads, not on the Internet of Vehicles. Of course, there is nothing wrong with this direction, because of the limitations of the times, the network bandwidth and the sensors. Price size is the bottleneck today, "single-machine" driverless is currently the most feasible way. In the early days of driverless driving, you can't make all the cars connected, all have built-in sensors, only after the driverless is mature. It is possible to implement the Internet of Vehicles, but this requires a long process.
Unmanned driving must be used in conjunction with the Internet of Things, and only everyone in the car enters the Internet of Vehicles to ensure absolute security. The current unmanned driving is still in its infancy, and unmanned driving without the Internet of Vehicles cannot guarantee absolute safety. Given the current level of driverlessness and the probability of an accident, the widespread adoption of driverless technology will cause the car company to close down. Nothing is more important than life.
In addition to the 5G car network used by driverless cars, telemedicine is also a new industry that has been born with the development of 5G. Thanks to the low latency of 5G networks, doctors can give more precise accuracy during remote surgery. The patient is operating in a sensitive area such as a human blood vessel. If the telemedicine delay is too high, it may cause the doctor to be inaccurate.
In addition to the above-mentioned 5G practical use, 5G actually provides a platform that may lead to more new industries. The 5G Internet of Things may bring more powerful momentum to social development. 5G is the key to realizing the Internet of Everything. Ring, 5G commercial will cause profound changes in the social economy.
