How many channels are typically available in the 2.4GHz frequency band?

In the 2.4GHz frequency band, the typical number of channels available for use in wireless communications is 11. This band is divided into overlapping channels, which are primarily used for Wi-Fi connectivity. Each channel has a specific bandwidth that allows for communication but also overlaps with adjacent channels, leading to potential interference.

The channels within the 2.4GHz band are spaced 5MHz apart, and while there are technically more channels available, in practice, only 11 can be used effectively in most regions, due to regulations and the overlap issue. For instance, when using channels 1, 6, and 11 in the 2.4GHz band, these channels do not overlap and are considered the "non-overlapping" channels, which help minimize interference among connected devices.

Due to these factors, 11 channels reflect the standard for the 2.4GHz frequency band in most Wi-Fi settings, making this the correct answer.
