Path loss definition in wireless communication

Path loss, which measures the loss of energy of a wave propagating between the transmitter and the receiver, is the main parameter in the design of wireless networks.

What is path loss in communication?

Path loss, or path attenuation, is the reduction in power density (attenuation) of an electromagnetic wave as it propagates through space. Path loss is a major component in the analysis and design of the link budget of a telecommunication system.

What are the main reasons for path losses?

The received power level is dependent on factors such as transmission power, antenna gains, frequency of operation and the distance between the transmitter and the receiver. Like any other gain or attenuation, path loss is also expressed in decibel (dB).

What are the two types of path loss model in wireless communication?

There are various types of path loss models in which few are two ray ground path model, free space path model and long distance path model .
