Fading


Fading is a phenomenon in telecommunications where the amplitude, phase, or frequency of a wireless signal changes rapidly over time or distance. This can lead to fluctuations in signal strength or interference, which can cause errors or dropped connections in wireless communication systems.

Fading can occur due to several factors, including multipath propagation, which occurs when signals reflect off of objects in the environment and arrive at the receiver from multiple paths with different phase and amplitude. Other factors include atmospheric conditions such as rain, fog, or ionospheric effects, which can cause changes in signal propagation.

There are two types of fading: slow fading and fast fading. Slow fading occurs over a long period of time and is due to changes in the environment, such as moving vehicles or changes in atmospheric conditions. Fast fading, on the other hand, occurs rapidly over a short period of time and is caused by the constructive and destructive interference of signals arriving at the receiver from different paths.
