Relative free space
WebFor radio transmission in free space, signal power is reduced in proportion to the square of the distance from the source, whereas in wire transmission, the attenuation is a fixed number of dB per kilometer. The following table is used to show the dB reduction relative to some reference for free-space radio and uniform wire. WebThe permittivity in vacuum (free space) is denoted as 0. Its value is 8.85418782E-12 Farads per meter (see our page on physical constants). No material has a permittivity lower than that of a vacuum. Relative permittivity (the dielectric constant) Materials other than vacuum have permittivity higher than 0, often they are referred to by their ...
