2.4 GHz

What is 2.4 GHz?

Various frequency ranges are available for WiFi. One frequency, for example, is the 2.4 GHz frequency. 2.4 GHz is the main or standard frequency. There, the distances between so-called channels are very small. In the 2.4 GHz frequency band, for example, only three overlap-free channels are available.

The 2.4 GHz frequency band is used by many households and in many apartment buildings. In addition, other devices beyond the router, such as microwaves, Bluetooth, cordless phones and others use this frequency band. This often results in a high WiFi load in the 2.4 GHz frequency band and thus in a lower data rate. But the 2.4 GHz frequency band does not only have disadvantages. While this frequency band can cause slower speeds, the 2.4 GHz frequency has a very long range and can serve many devices simultaneously.

2.4 GHz Advantages

Long range, for example spread over a large house or into the garden
Can pass through solid objects in particular, e.g. walls
Suitable for almost all WiFi-capable standard devices and hardware

However, if too many devices are connected to the 2.4 GHz band at the same time, the WiFi may become sluggish or interfered with.

What is the difference between 2.4 GHz and 5 GHz?

The 2.4 GHz frequency band is more crowded compared to the 5 GHz frequency band, as it is used by more devices and only 11 channels are available instead of 23. The number of channels available depends on the WLAN regulations in the region.

In general, the difference between 2.4 GHz and 5 GHz is the range and speed. If a further range is desired, the 2.4 GHz frequency band should be selected. If higher performance or speed is required, for example in streaming or gaming, the 5 GHz frequency band should be used.
