This 1-way path loss calculator uses the familiar Friis equation
. It is
applicable in the case of something like a transmitter broadcasting to a distant receiver. The transmission medium
is assumed to be air in a line-of-site configuration.
As a rule of thumb, do not specify a distance (d)
less than the wavelength or the results become unreliable.
The calculator originally on this page has been
removed because of compatibility issues with outdated Microsoft OWC components. A 1-Way Path Loss
Calculator is included in
RF Cafe Calculator Workbook
