"WebSignal power flux density is the amount of signal power that crosses a unit surface area where the surface is perpendicular to the direction of the propagation of the signal. As the signal traverses larger distance from the transmitter, the power diverges out in space. As the same power is dispersed over a larger cross sectional area, the flux density value … " - Power and noise
