What is the difference between the 2.4 GHz and 5 GHz Wi-Fi network – Internet – Tecnoblog

It is common to find in our routers two options of frequency signals for the internet. But is there any difference between 2.4 GHz and 5 GHz? Which one is best for your home? Should we prioritize each other? Come with me, because in the lines below you will learn more about these types of networks.

Both 2.4 GHz and 5 GHz (GigaHertz) are frequencies that communicate Wi-Fi signals with devices. Many modern routers already have both options for home use, this ends up creating confusion for many people, as we don’t know which one to use on our television, cell phone, video game console, etc.

In addition to the change in nomenclature, there are occasional distinctions that need to be explained. It is worth mentioning that it is not just for bringing a larger number that makes one much better than the other.

The main differences between 2.4 GHz and 5 GHz

Because both are basically Wi-Fi signals, they bring similarities such as their use (connect to the internet) and the transmission device (usually the same router). Therefore, it is common to find Wi-Fi networks with the same nomenclature, but ending with their frequency numbers. An example of this would be “Tecnoblog_5G” and “Tecnoblog_2.4G”.

But what about the differences?


The 2.4 GHz transmits, in perfect conditions, about 150 Mbps (megabit per second). Already the 5 GHz can reach absurd 1 Gbps (gigabit per second). In this way, it is quite obvious which is the best in this regard, but we cannot forget that there are devices that do not recognize the 5 GHz signal, for example. Therefore, it is no use focusing solely on the frequency that delivers the most internet speed.


At this point, it’s hard not to recommend 2.4 GHz. The range of this signal is longer compared to its alternative. While its distance is close to 20 meters, the 5 GHz has difficulty going beyond 15 meters. It may not seem like a huge difference, but in large homes, it ends up having a big impact on daily use.


Because it is an older frequency and used by several different devices, 2.4 GHz suffers more radio signal interference. This can result in unstable connections and download and upload speed drops. This sort of thing happens much less regularly when using 5 GHz.

On the other hand, the first mentioned signal manages to overcome barriers such as walls with greater ease, something that its alternative has greater difficulty.

What should I prioritize in my home?

It all depends on which devices you intend to connect to the internet.

The vast majority of them are compatible with 2.4 GHz, from cell phones to smart televisions. This means that if you prioritize this signal, you will almost certainly have no problem with compatibility. Also, because of the greater network range, you will be able to use your notebook in the room farthest from the router, for example.

On the other hand, if you are an avid person to play your games online, then you will want as much speed as possible in your games (if you use Wi-Fi). Modern video game consoles like the Xbox Series, PlayStation 5 and Nintendo Switch are compatible with the 5 GHz frequency. Therefore, in addition to offering a higher amount of Mbps, interference will be as little as possible.

With all this in the balance, it’s easier to understand your internet needs. Just remember what type of device you are going to use and how far it will be from the router. For casual use, these tips are enough to put your mind at ease.

Now that you know the differences between 2.4 GHz and 5 GHz, tell us which one you use the most in your home. Do you have any preferences?
