In the home network, WLAN is mainly available in two frequencies: 2.4 and 5 GHz. A frequency is, for example, a 5 GHz frequency, which offers higher speeds, fewer incidents of interference and usually less heavy load. The range of 5 GHz is comparatively short and is therefore particularly suitable for smart TVs or game consoles, for example, which are usually close to the router and at the same time require a stable and fast connection to the WLAN.
In summary, the 5 GHz band offers a shorter range, but transmits data at a higher speed. Newer routers have both 2.4 GHz WiFi and 5 GHz WiFi, so users usually have the choice of which band they want to use, if circumstances permit.
Risk of confusion: 5 GHz WLAN does not transmit 5G mobile signals and does not connect to them. The 5G mobile standard does not overlap with the 5 GHz WLAN.
However, the range decreases at a higher frequency. The 5 GHz network therefore has a significantly lower range compared to the 2.4 GHz frequency and is therefore limited to one floor or floor, for example. Walls in particular slow down connectivity. At the same time, the use of the 5 GHz frequency is hardware-dependent. Many older routers and devices do not yet support the connection to this network.
The 5 GHz band is generally less crowded than the 2.4 GHz band because it is used by fewer devices and 23 channels are available for devices, while the 2.4 GHz band only has 11 channels. The number of channels that are available depends on the WLAN regulations in the region.
In general, the difference between 5 GHz and 2.4 GHz is speed and range. When higher performance or speed is required, for example in streaming or gaming, the 5 GHz frequency band should be used. If a wider range is required, the 2.4 GHz frequency band should be selected.
