4G is already fast enough, why do we need 5G?

Whether it is the development of the Internet or the power of smartphones, it is certain that they both require the Internet. Although the emergence of WiFi has solved the problem of indoor networks, fundamentally speaking, the truth is to be able to access the Internet anytime and anywhere. The emergence of 4G networks has largely met daily needs, but 5G has gone a step further.

What is 5G Technology

In the field of mobile communications, the first generation is analog technology, the second generation realized digital voice communication, the third generation is the well-known 3G technology, characterized by multimedia communication, the fourth generation is the 4G technology that is being rolled out, and its communication speed has greatly improved, marking the entry into the wireless broadband era, and 5G technology is the fifth generation of mobile communications.

Two different views on 5G

***The first view is that 5G will be a brand new technology. 5G is not just a technological update, but a huge leap forward and a revolution, which means that the network architecture must be upgraded. 5G's network requirements will be completely different from 4G. Although the 4G technology currently used will continue to evolve, no matter how 4G evolves, it will not become 5G. 5G will be a brand new technology.

The second view is that 5G is the inevitable evolution of 4G technology. Although any generation of technological development cannot be a repetition of the previous generation of technology, if the new generation of technology is the same as the previous generation, then what is the new generation? Therefore, 3G technology is different from 2G, and 4G is different from 3G. Its technical principles, problem-solving methods, deployment methods, and capabilities are all different. However, without the foundation of the previous generation of technology, or the next generation does not inherit the technology of the previous generation, it is impossible to achieve a revolutionary upgrade.

What are the advantages of 5G

Simply put, 5G will be faster, with high performance, low latency and high capacity. For many consumers, the value of 5G lies in its faster speed than 4G (peak speed can reach tens of Gbps). For example, you can download a high-definition movie in one second, while 4G may take 10 minutes. It is precisely because of this unique advantage that the industry generally believes that 5G will play an important role in fields such as driverless cars, VR and the Internet of Things.

Why do we need 5G technology?

I believe many people will ask if we need 5G now? Indeed, when 4G can meet so many demands nowadays, 5G does seem redundant, but if you think about it carefully, it is not the case. ***, with the development of technology, there will naturally be a kind of accumulation and evolution of technology, and the birth of 5G is inevitable. In addition, in the future, we may face a 1,000-fold increase in data capacity, 10 to 100 times the number of wireless device connections, 10 to 100 times the user rate requirements, 10 times longer battery life requirements, etc. In other words, the future 4G network may not be able to meet these demands, so 5G has become an inevitable product.

Is there any connection between 5G WiFi and 5G technology?

The answer is no. The so-called 5G WiFi (802.11ac) refers to the fifth generation of WiFi transmission technology, and it runs on the 5Ghz radio wave frequency band. It is not the 3G, 4G or 5G network on the wide area network we are talking about.
