2.4 GHz vs. 5 GHz: Which Frequency To Use?

Both the 5 GHz and 2.4 GHz frequencies have their advantages and disadvantages, so it’s important to choose the right one based on your needs. The answer to the question of which frequency is better is not as straightforward as it seems. To determine the right frequency, users need to take a look at various factors that can affect their connection. Let's take a look at some of them.

The Area To Be Covered

If users need to cover a large area (like an office building or a multi-level house), then they should opt for the 2.4 GHz frequency. This will ensure that the connection is strong enough to cover the entire area without any dropouts or slowdowns.

The Devices To Be Connected

If users are connecting a variety of devices that may not be 5 GHz compatible, then they should opt for the 2.4 GHz frequency. This is because 5 GHz devices won’t be able to connect to the 5 GHz network, which could lead to slow speeds or even dropped connections.

The Type Of Activity To Be Performed

If users are looking for faster speeds and more stability, then 5 GHz is the way to go. 5 GHz is better for activities that require more bandwidth, such as streaming HD video or gaming. On the other hand, 2.4 GHz is better for activities that don’t require as much bandwidth, such as scrolling through social media or browsing the web.

Number of Devices Connected

If users need to connect a large number of devices, 5 GHz is the better option. 5 GHz networks can support up to 30 devices without experiencing slowdowns or dropped connections. Similarly, 5 GHz networks are less likely to be overwhelmed by large amounts of traffic.

Nowadays, most WiFi routers come with dual-band technology that makes it easier for users to choose the right frequency. Users can choose between the two frequencies depending on their needs easily. The two frequencies will be shown as two different routers, and users can just choose which one to connect to.

So, now let's finally answer the question:

Does 5GHz WiFi Go Through Walls?

Yes, 5Ghz WiFi can go through walls, but it is more likely to be weakened or blocked by obstacles like walls, floors, and ceilings. 5Ghz WiFi is best suited for smaller areas with fewer obstacles, where the signal can reach further, and speeds can remain higher.
