How many channels does the 2.4 GHz band support?

The 2.4 GHz band supports a total of 14 channels, although not all channels are available for use in every country due to regulations. In the 2.4 GHz frequency range, there are 14 channels spaced 5 MHz apart. However, channels are often grouped, as they overlap, which is why only a subset of these channels is typically used in practice for effective Wi-Fi deployment, especially to minimize interference.

In the United States, for example, channels 1, 6, and 11 are commonly used because they do not overlap, providing the best opportunity for multiple networks to coexist without causing interference. Other countries may allow the use of additional channels, making the total possible channels 14. Understanding the number of channels available in the 2.4 GHz band is critical for optimizing Wi-Fi performance and reducing interference in wireless networks.
