Explanation
Wireless communication usually involves a data exchange between two devices. A wireless LAN goes even further, many devices can participate in sharing the medium for data exchanges. Wireless LANs must transmit a signal over radio frequencies (RF) to move data from one device to another. Transmitters and receivers can be fixed in consistent locations, or they can be mobile and free to move around. A WiFi channel is the medium through which our wireless networks can send and receive data. The 2.4 GHz band has 11 channels and the 5 GHz band has 45 channels. Selecting the proper WiFi channel can significantly improve your WiFi coverage and performance. In the 2.4 GHz band, 1, 6, and 11 are the only non-overlapping channels. Selecting one or more of these channels is an important part of setting up your network correctly.
