Channel width in Wi-Fi refers to the size of the frequency band that a wireless router or access point uses to transmit and receive data. Think of it like a highway: a wider road allows more vehicles to travel simultaneously, which increases the overall flow of traffic. In Wi-Fi terms, a wider channel means more data can move between devices and the router at the same time, which generally translates into faster speeds for individual connections. The three most common channel widths used in modern Wi-Fi networks are 20 MHz,…
