It is said that WiFi will disappear after 5G becomes popular. Is this really the case?

5G is good, 5G is wonderful, and 5G will be great after commercial use. The media and manufacturers are constantly hyping up the benefits of 5G networks, including super fast speeds, large network capacity, low latency, and a variety of applications. For a time, the view that 5G will kill WiFi quickly gained popularity. What kind of grudge does 5G have against WiFi? Even well-known domestic and foreign media (such as Bloomberg) agree with this view. Since everyone thinks so, let me sing a different tune. Although 5G has many advantages, WiFi will definitely not disappear from people's lives.

How come everyone agrees, but you are the only one who disagrees? In fact, we can see some clues from this year's CES. Remember the 5G router released by Samsung? It receives 5G network signals and converts them into WiFi signals for smart devices at home. If 5G really wants to make WiFi dead, all devices in the home should be equipped with 5G network modules. Who would still use WiFi to surf the Internet? Wait, is it realistic to install 5G modules for so many devices in the home and let them access the mobile network at the same time?

The advantage of 5G lies first in its frequency band. Through low frequency band and carrier aggregation technology, the network capacity is greatly improved. Now we can clearly feel the high Internet delay and slow Internet speed in crowded places such as subways and stations. In the 5G era, the network capacity will be greatly improved, and the above phenomenon will not occur, which will improve the user experience. It is also this feature that makes people think that 5G is so good. What is our WiFi? This guy is sometimes stuck and slow. Long live 5G!

It is true that 5G has many benefits, and in actual applications it will definitely be deeply integrated with WiFi networks. The speed of WiFi is also getting faster and faster, and now the wireless transmission rate can exceed 1000M. With the broadband speed increase and the continuous innovation of WiFi protocols, we will still connect to WiFi networks when we return home and enter the company, and it is a high-speed WiFi network. The 5G network will bring us a better user experience in the subway and outdoors. And it will play a better role in special fields such as telemedicine, Internet of Vehicles, mobile VR and other applications.

Especially in big cities, where high-rise buildings are densely populated, the density of buildings we live in is also very high. When everyone accesses the mobile network at the same time, it is inevitable that mutual interference will occur, and the load on the base station will increase, resulting in a decrease in network speed. In indoor environments, it is more convenient to use WiFi for short-distance transmission. Now almost all smart devices have WiFi modules, and most IoT devices are also equipped with WiFi modules. The export only uses one public IP address, and it does not matter if a large number of addresses are occupied within the LAN. It is very convenient for users to manage these devices under their own WiFi network.

WiFi and 5G networks are supposed to complement each other, so why are they considered to be enemies that need to be killed?
