Path Loss

In telecommunications, path loss refers to the reduction in power density (attenuation) of an electromagnetic wave as it propagates through space.

Path loss occurs due to several factors, including the spreading of the wavefront, absorption by atmospheric gases, and scattering by obstacles such as buildings, trees, and hills. The amount of path loss depends on the frequency of the electromagnetic wave, the distance it travels, and the surrounding environment.

Path loss is an important consideration in the design and operation of wireless communication systems. It determines the maximum distance between a transmitter and receiver, the minimum transmitter power required to achieve a given signal strength, and the maximum capacity of the communication channel.
