Free Space Path Loss is used the calculate the attenuation (reduction) of signal strength between two antennas. Free Space Path Loss assumes the space between the two antennas is an obstruction free, line-of-sight straight path through the air. This calculation can be used as part of a more in-depth link budget analysis when planning the design of a communication system.
