Propagation constant — The propagation constant of an electromagnetic wave is a measure of the change undergone by the amplitude of the wave as it propagates in a given direction. The quantity being measured can be the voltage or current in a circuit or a field vector… … Wikipedia
Loss tangent — The loss tangent is a parameter of a dielectric material that quantifies its inherent dissipation of electromagnetic energy. The term refers to the tangent of the angle in a complex plane between the resistive (lossy) component of an… … Wikipedia
Propagation path obstruction — In telecommunication, a propagation path obstruction is a man made or natural physical feature that lies near enough to a radio path to cause a measurable effect on path loss, exclusive of reflection effects. An obstruction may lie to the side,… … Wikipedia
Line-of-sight propagation — refers to electro magnetic radiation including light emissions traveling in a straight line. The rays or waves are diffracted, refracted, reflected, or absorbed by atmosphere and obstructions with material and generally cannot travel over the… … Wikipedia
Path loss — (or path attenuation) is the reduction in power density (attenuation) of an electromagnetic wave as it propagates through space. Path loss is a major component in the analysis and design of the link budget of a telecommunication system.This term… … Wikipedia
Radio propagation model — A radio propagation model, also known as the Radio Wave Propagation Model or the Radio Frequency Propagation Model , is an empirical mathematical formulation for the characterization of radio wave propagation as a function of frequency, distance… … Wikipedia
Non-line-of-sight propagation — Non line of sight (NLOS) or near line of sight is a term used to describe radio transmission across a path that is partially obstructed, usually by a physical object in the innermost Fresnel zone. Many types of radio transmissions depend, to… … Wikipedia

Log-distance path loss model — The log distance path loss model is a radio propagation model that predicts the path loss a encounters inside a building or densely populated areas over distance.Applicable to / Under conditionsThe model is applicable to indoor propagation… … Wikipedia
Free-space path loss — In telecommunication, free space path loss (FSPL) is the loss in signal strength of an electromagnetic wave that would result from a line of sight path through free space, with no obstacles nearby to cause reflection or diffraction. It does not… … Wikipedia
