2,4GHz - 5GHz Wi-Fi, what's the difference ?

This option, often proposed on routers to optimize your connection stability in your home is often unknown. The question then is, what is the difference between these two frequencies in order to understand why they exist?




2,4GHz - 5GHz

In terms of interference, the 5GHz frequency is less likely to have interference problems. The reason for this is that most devices like those running Bluetooth, smartphones, microwaves and computers use a 2.4GHz frequency.
Thus, you'll be more likely to have some using devices on this frequency.


On a matter of scope, the 5GHz band has one shorter than 2.4GHz. This is for the simple reason that in radio frequencies, the higher the frequency, the shorter the range. As a result, the 2.4GHz frequency has a longer range than that of 5GHz.
When it comes to browsing the internet from a computer or checking email, the 2.4GHz band is recommended because these applications do not require too much bandwidth and work well at a fairly high distance.

 5GHz frequency possesses more possibilities in terms of wireless compared to the 2,4GHz one.
We get so higher performances with this one. Otherwise, this frequency is motsly used for an uninterrupted flow. It is therefore recommended to stream streaming media, music, photos and videos on your home network using this 5GHz frequency.
Finally, if you have the option, prefer the 5GHz Shadow 2.4GHz for a better experience.
IMPORTANT: Configuring the 40MHz channel width on the 2.4GHz network will allow you to use 2/3 of the entire Wi-Fi band, making it more likely to interfere. It is best to use 40MHz if you live in areas with less wireless presence.
TIP: If you use the 5GHz frequency, make sure your wireless devices and adapters have 5GHz capacity to access the network; otherwise, do not change the default frequency of the router that is 2.4GHz.
