What does the term 'fade' refer to in relation to a wireless LAN?

The term 'fade' in relation to a wireless LAN refers to the loss of signal strength or quality as devices move farther away from an access point. In wireless networking, as the distance between a device and the access point increases, the strength of the transmitted signals diminishes due to several factors including physical obstructions, environmental interference, and attenuation. This phenomenon can lead to reduced data rates, increased latency, or even a complete loss of connection. Understanding this concept is crucial for network design and optimization, as it emphasizes the need for adequate coverage and strategies to mitigate signal degradation in various environments.
