tropospheric radio scattering
1Radio 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.,… …
2Tropospheric scatter — (or troposcatter) is the scattering of distant TV and FM radio stations by the troposphere so that they travel farther than the line of sight. This effect sometimes allows reception of stations up to a hundred miles away.The phenomenon has been… …

4Non-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… …

6Meteor burst communications — Meteor scatter propagation as used by SNOTEL Meteor burst communications (MBC), also referred to as meteor scatter communications[1], is a radio propagation mode that exploits the ionized trails of meteors during atmospheric entry to establish… …
7Broadcast range — A broadcast range (also listening range for radio, or viewing range for TV) is the service area that a broadcast station or other transmission covers via radio waves (or possibly infrared light, which is closely related). It is generally the area …
8Rayleigh fading — is a statistical model for the effect of a propagation environment on a radio signal, such as that used by wireless devices.Rayleigh fading models assume that the magnitude of a signal that has passed through such a transmission medium (also… …
