Note: Free-space Loss is primarily caused by Beam Divergence , ''i.e.'', signal energy spreading over larger areas at increased distances from the source, and by the Inverse Square Law of Electromagnetic Radiation . The equation for free-space loss is below where is the signal wavelength, f is the signal frequency, R is the distance or radius of the signal from the transmitter, and c is the speed of light in the signal transmission medium. Note that the units used should be consistent, e.g., and R in meters, and c in meters per second. Source: from Federal Standard 1037C and from MIL-STD-188 |
