![]() ![]() Free-Space Path Loss (wavelength): This computes the FSPL as function of wavelength instead of frequency.We've paired this FSPL calculator with a short text describing: Antenna gain Free space path loss definition The free space path loss formula and How to calculate free space path loss. This equation is not accurate for short distances. Our free space path loss calculator can help you obtain the attenuation of signal strength through free space between an emitter and a receiver. This equation is only accurate at a distance from the transmitter where spherical spreading can be assumed. This equation uses the frequency and the constant for speed of light to calculate the FSPL. These calculators help with unit conversions, VSWR calculations, attenuator design, antenna design, radars, and various other basic calculations that are often required. SATNow has the largest selection of online calculators for the Satellite Industry. Just enter the value and click calculate. The formula for the Free-Space Path Loss using frequency is: everything RF RF Calculators RF Calculators A series of RF calculators for radio frequency engineers. This calculator is made to calculate the Free Space Path Loss. However, this can be automatically converted to a real or percent via the pull-down menu. INSTRUCTIONS: Choose units and enter the following:įree-Space Path Loss (FSPL): The calculator returns the loss in dB. ![]() The Free-space Path Loss calculator computes the loss of signal strength on a line-of-sight path which has no obstacles or other disturbances based on the distance ( d) and the frequency ( f) of the signal. ![]()
