How is dB path loss calculated?

L = fspl( R , lambda ) returns the free space path loss in decibels for a waveform with wavelength lambda propagated over a distance of R meters.

How you can mathematically represent path loss?

In the study of wireless communications, path loss can be represented by the path loss exponent, whose value is normally in the range of 2 to 4 (where 2 is for propagation in free space, 4 is for relatively lossy environments and for the case of full specular reflection from the earth surface—the so-called flat earth ...

What is path loss factor?

What is Path Loss? Path loss (PL) refers to the loss or attenuation a propagating electromagnetic signal (or wave) encounters along its path from transmitter to the receiver. As a result of path loss, the received signal power level is several orders below the transmitted power level.
