Whether we have seen our mobile phone display "2.4GHz" or "5GHz" next to the name when connected to WiFi, or when purchasing our router, or we have no idea what this article is talking about, most people do not know what this number means and what to prefer! So let's explain first what these numbers mean, their differences, and what to choose!

Wi-Fi 2.4 GHz

The frequency band known as 2.4GHz is famous for its long range and ability to penetrate walls and solid objects. However, it is also more susceptible to interference from other devices, such as microwaves, as well as other 2.4GHz devices, which unfortunately is almost everything wireless around us operates on 2.4GHz. These interferences negatively affect our internet connection.

Wi-Fi 5 GHz

The 5 GHz frequency band is known for its high speed. The range is quite small and it is not known for its ability to penetrate solid objects. For this reason, most 5GHz routers also support simultaneous 2.4GHz connection and it is recommended to use the 5GHz when we are in the same room as the router. Interference in the 5GHz range is not common because it is not everywhere around our router, both because there are few devices that use the 5GHz and because it does not have a long range.

What to choose between the two?

The choice between 2.4 GHz and 5 GHz depends on your situation. If you need a strong, reliable signal that can cover a large area and penetrate walls, the 2.4 GHz band may be the best choice. However, if speed is your priority and you are in a location with a strong signal, the 5 GHz would be the better choice.

Note that 5 GHz can reach up to 1,300 Mbps, which is almost double the speed compared to a 2.4 GHz connection that can reach up to 600 Mbps under ideal conditions. The most common is to see up to 150 Mbps in our home with 2.4 GHz. If you are one of the lucky ones with fiber optic 200+ Mbps, then the ideal is 5 GHz.
