Fast speed, no delay, no explosion. What is 5G?

One of the hot spots in these two years is 5G. Every time the news about 5G comes out, it will attract everyone's attention, but there should still be many people who understand 5G only fast, ultra-fast and extremely fast, which is a single aspect. It can also be said that it is a general understanding, and I don't know what 5G is. In fact, 5G is the abbreviation of the fifth generation mobile communication technology. Speaking of the fifth-generation mobile communication technology, was there a fourth-generation mobile communication technology before that? Let me give you a general explanation. 1G technology was born in 1980s, and it is the original calling technology to simulate wired telephone. Simply put, just make a phone call. In the era of 2G technology, voice calls are still the mainstay, and the network speed is only 10 KPS to 100 KPS. Even sending emails directly is not realistic, so I can only help to send text messages.

In fact, 5G, like other cellular data, is a system that combines cellular networks into a large area. It sends all kinds of coded data by radio waves, and then transmits them to all areas covered. Then the base station is connected to the main backbone network, which can be wired or wireless. Each generation network has different coding methods. The coding method adopted by 5G is OFDM, that is, orthogonal frequency division multiplexing technology, which realizes parallel transmission of high-speed serial data, thus shortening network delay and improving efficiency.

Since 3G technology, it has supported high-speed network transmission. At that time, the emergence of 3G was a great improvement in speed. The downlink speed can reach up to 7.2mbps, and the uplink speed can reach 5.6mbps. Later, it was even faster when it came to 4G technology, so when 5G appeared, it gave everyone the feeling of being fast. This is the traditional inherent concept of other network technologies. So it's not surprising.

At present, 5G technology is becoming popular, and the number of users in China is less than 1 100 million. However, the popularity of 5G is also the general trend. 5G technology is not only fast, but also the key aspect of speed, but it is definitely not the only advantage.

High bandwidth alone can solve many problems in present life without delay. In the medical field, senior surgeons can perform operations remotely without visiting the site. We use all kinds of electronic equipment and don't need storage tools. Ultra-high-speed, delay-free network can realize the cloud operation of various large-scale games and applications anytime and anywhere. 5G technology is still developing and improving, and there will be more possibilities in the future.
