Non-Overlapping Wi-Fi channels
Data is typically sent between two devices during a wireless connection. More devices can join in sharing the medium for data exchanges on a wireless LAN. To transfer data from one device to another, a wireless LAN needs to emit a signal using radio frequencies (RF). In addition to being mobile and free to roam about, transmitters and receivers can also be fixed in specific areas. Our wireless network’s ability to transmit and receive data across a Wi-Fi channel. While the 5 GHz frequency contains 45 channels, the 2.4 GHz band only has 11. Your Wi-Fi coverage and performance can be greatly enhanced by choosing the appropriate Wi-Fi channel. The only non-overlapping channels in the 2.4 GHz frequency are channels 1, 6, and 11. A crucial step in successfully configuring your network is deciding on one or more of these channels.
Wireless Principles in CCNA
Wireless communication takes place over free space over RF (Radio Frequency), where one device (transmitter) sends a signal to another device (receiver). Two devices (transmitter and receiver) must use the same frequency (or channel) to communicate with each other. Radio frequencies can cause interference when many wireless devices communicate at the same time. As the number of devices increases, the interference increases. The following topics describe the concept of wireless principles in CCNA.
