What are the differences between 5gwifi and 2.4G?

What are the differences between 5g WiFi and 2.4G? What are the advantages and disadvantages of the two? With the continuous progress of network technology, the transmission speed of the network is also constantly improving. In this environment, the router with strong signal now also has 2.4G signal and 5g signal. I believe many users do not know the difference between the two. Now this article will give you a detailed introduction of what are the differences between 5g WiFi network and 2.4G? At the same time, it will introduce the advantages and disadvantages between the two.
 
 
Why does 4G signal pass through the wall?
 
At the same distance from the router, 5g signal is weaker than 2.4G signal, which is determined by the physical characteristics of electromagnetic wave: the longer the wavelength, the less attenuation, and it is easier to bypass the obstacles and continue to spread. 5g signal has high frequency and short wavelength, while 2.4G signal has low frequency and long wave length. Therefore, 5g signal has greater attenuation when passing through obstacles, and its wall crossing ability is weaker than that of 2.4G signal. This situation exists in all dual band wireless routers.
 
Note: the following is the loss formula of 2.4G and 5.8G propagating in free space (where f is frequency in MHz; D is distance in KM)
 
The attenuation formula of radio electromagnetic wave in free space is L = 32.5 + 20lgf + 20lgd.
 
The attenuation formula of 2.4G band: L1 = 100 + 20lgd;
 
The attenuation formula of 5.8G band is L2 = 108 + 20lgd.
 
The above formula shows that the attenuation of 5.8G is higher than that of 2.4G, and the corresponding coverage distance is smaller.
 
If 5g signal is weaker than 2.4G signal, will network speed be slow?
 
Not necessarily, network speed is not only related to signal strength, but also to channel quality. If you watch 4G band 2.3 band, it is possible to block the 2.3 band signal after watching the 4G band. For some applications, such as real-time downloading and voice delay, it is more suitable.
 
What are the advantages and disadvantages of 2.4G and 5g Wi Fi?
 
 
Which frequency band is more suitable?
 
Through the above comparison, we can see the advantages and disadvantages of 2.4G and 5g frequency bands, but not only one of them can be selected. Most of them have complex use environment, diverse terminals and large amount of access. Therefore, the combination of the two bands can give full play to the wireless advantages. If you are a home user, it is recommended to choose a dual band router. The most appropriate frequency band of 2.4G or 5g can be selected for less mobile objects such as IPTV and notebook; mobile terminals can use different frequency bands in different locations, so as to give full play to the advantages of each frequency band.
 
After reading the full text, you have understood the difference between 5g WiFi network and 2.4G network. At the same time, the advantages and disadvantages of the two are compared in the form of a table, so that users can see it at a glance. Now users can choose which band of router to use according to their own needs.
