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
Path integral formulation — This article is about a formulation of quantum mechanics. For integrals along a path, also known as line or contour integrals, see line integral. The path integral formulation of quantum mechanics is a description of quantum theory which… … Wikipedia
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
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
Path loss — Affaiblissement de propagation L’affaiblissement de propagation, aussi connu comme affaiblissement de parcours ou par son nom anglais de path loss, caractérise l affaiblissement que subit une onde électromagnétique lorsqu elle parcourt une… … Wikipédia en Français
Path — Cette page d’homonymie répertorie les différents sujets et articles partageant un même nom. Path ou PATH peut faire référence à : En informatique Le chemin d accès d un fichier ou d un répertoire, en informatique. PATH : La variable d… … Wikipédia en Français
Path profile — In telecommunication, a path profile is a graphic representation of the physical features of a propagation path in the vertical plane containing both endpoints of the path, showing the surface of the Earth and including trees, buildings, and… … Wikipedia
Path loss — Die Artikel Pfadverlust und Dämpfung überschneiden sich thematisch. Hilf mit, die Artikel besser voneinander abzugrenzen oder zu vereinigen. Beteilige dich dazu an der Diskussion über diese Überschneidungen. Bitte entferne diesen Baustein erst… … Deutsch 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
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
Radio propagation — is a term used to explain how radio waves behave when they are transmitted, or are propagated from one point on the Earth to another. [ H. P. Westman et al, (ed), Reference Data for Radio Engineers, Fifth Edition , 1968, Howard W. Sams and Co.,… … Wikipedia
