How good is 5G?

In the last era of communication, we often had some sayings, for example, "no signal." However, this word has been used less and less recently. At present, the achievements of the construction of the base stations of the three major operators in China have attracted worldwide attention. In China's vast land, almost all coverage can be achieved. Poor mountainous areas, border deserts, and even Everest's 6000. The headquarters of the company can see the coverage of the operator's signal. In this era, what do we often say? It’s “no traffic” and “the network is not very good”. Is there any connection between this traffic network and the signal? In fact, this is two different ways of signal transmission. The traffic and network we usually refer to are the signals and data traffic of cellular mobile communications. At present, we live in the era of a 4G network. The so-called 4G is not a technical term at the scientific and technical level. It is simple and simple. It means the fourth generation of cellular mobile communication. In the 4G era, we enjoy faster network services, greater data traffic, and lower network latency. In recent days, we can already see that the 5G era is coming to us. So what is the magical power of 5G, so that everyone is looking forward to it? Xiaobian, this article, tells everyone how good 5G is.

5G is actually a relatively abstract concept. It does not refer to any kind of data signal, nor is it any use scheme. This only abstractly represents the meaning of the fifth generation. Specifically, what are the 5G usage schemes? As can be seen from the authoritative documents of international injuries, the currently widely accepted use schemes refer to eMBB, URLLC, and mMTC, which refer to three different usage scenarios: First, faster and more for consumers. A reliable mobile network is intuitively faster. Second, a very low-latency, reliable network for industrial automation or remote precision operation. Intuitively, the network delay is lower. 3. When connecting a large number of devices, it is used for transmission. In terms of machine communication of data, it is intuitive to see that the devices connected to the network are more large.
Of course, there are very detailed terms and numerical rules for 5G, such as 5G peak data rate, mobility requirements, delay, link density, etc., here is not explained in detail, we only need to know, once 5G After the popularization, there will be many operations that cannot be completed in the 4G era. For example, 5G networks can support the transmission of high-definition video and even augmented reality content, because the network speed is faster and the bandwidth is wider, which can support real-time remote surgery because of delay. Lower, can support large-scale industrial automation, and even low-latency synchronization of long-distance machine communication. The three usage scenarios mentioned above seem to be a bit rough, and there is no way to actually imagine the use scenarios of the 5G era. Then Xiaobian will give two examples to illustrate the future use of 5G in life, I believe that you can imagine when you look at it.

The first thing to say is automatic driving. In the current automotive industry, new energy vehicles are one of the hot spots, and the other is automatic driving, but the automatic driving has not been realized in the 4G era. Despite the huge investment, the world's major manufacturers have only made small Part of the sample car, there is no way to carry out large-scale popularization, which has two obstacles. The first is that the road driving skills mastered by machine learning require large-scale data training, and the second is the difference between different self-driving cars. Intercommunication and sharing of road conditions. The 5G network speed and low delay characteristics are undoubtedly a very important breakthrough for automatic driving.

The second example to be mentioned is telemedicine. It is also mentioned above that the URLLC usage scheme is a very low latency reliable network for industrial automation or remote precision operation. This component will bring about a very significant change in the healthcare field. The low latency of a 5G network is equivalent to a The key, you can use this key to open a new world, you can see the unlimited possibilities of this industry. Medical resources that were once difficult to distribute evenly because of geography will be redistributed using 5G. The low-latency network of 5G means that telemedicine, remote physical rehabilitation, etc. are possible, and longer-term plans such as AR remote precision surgery, etc. It is a imaginable scene in the future.

In addition to the above two examples of daily routines, 5G has a lot of benefits waiting for us to explore, although it will take a year or two to fully come to each of us in the 5G era, but imaginable Yes, applied science is always for the benefit of mankind, and the 4G era has allowed us to achieve many things that we could not imagine in the past, even with surprising changes compared to five years ago, then the benefits of 5G are natural. Needless to say, we will change our lives in various fields, and there are countless exciting possibilities. Xiaobian believes that there will be many new technologies that are inter-generational and will be born out of the 5G era to improve our daily lives. The level of comfort. Let us wait for the arrival of the 5G era and embrace the new possibilities!
