Detailed explanation-1: -Essentially, WiFi channels are smaller bands within WiFi frequency bands that are used by your wireless network to send and receive data. Depending on which frequency band your router is using, you have a certain number of WiFi channels to choose from: 11 WiFi channels are in the 2.4 GHz frequency band.
Detailed explanation-2: -The channel frequencies in the 2.4 GHz band range from 2.412 GHz to 2.472 GHz. Within a band, there will always be a variety of frequency ranges to help manage the network traffic. In turn, these will determine speed and stability. The lower the frequency, the slower but more reliable the network will be.
Detailed explanation-3: -Every channel is associated with a range of frequencies called the frequency band. The difference in the highest and lowest frequencies in the band is known as the bandwidth of the channel. It is a characteristic of the channel and signifies the information carrying capacity of the system.
Detailed explanation-4: -The 802.11 standard provides several distinct radio frequency bands for use in Wi-Fi communications: 900 MHz, 2.4 GHz, 3.6 GHz, 4.9 GHz, 5 GHz, 5.9 GHz, 6 GHz and 60 GHz. Each range is divided into a multitude of channels.
