The path loss exponent (PLE) is a parameter indicating the rate at which the received signal strength (RSS) decreases with distance, and its value depends on the specific propagation environment.

What is the formula for path loss?
Definition of Path Loss Mathematically
d is the distance between the transmitter and receiver and λ is the wavelength of the signal. By definition, path loss is the ratio of the transmitted power to the received power. From the above equation, we can get the ratio of Pt and Pr.
What is the typical value of path loss exponent?
Typical values of path–loss exponents range between 1.5 and 5.
How is path loss measured?
The path loss is measured by the method of directly measuring the frequency transfer function by scanning the specified frequency band using Vector Network Analysis (VNA). And in the process of measurement, the same VNA is the transmitting end and the receiving end, in [4]–[6].
What is meant by path loss?
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.
