Ionospheric sounding — In telecommunication and radio science, an ionospheric sounding is a technique that provides real time data on high frequency ionospheric dependent radio propagation, using a basic system consisting of a synchronized transmitter and receiver. 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

Maximum usable frequency — (MUF) describes, in radio transmission, using reflection from the regular ionized layers of the ionosphere, the upper frequency limit that can be used for transmission between two points at a specified time, independent of transmitter power. This … Wikipedia
Nakagami fading — Unfortunately, mobile radio links are subject to severe multipath fading due to the combination of randomly delayed, reflected, scattered, and diffracted signal components. Fading leads to serious degradation in the link carrier to noise ratio… … Wikipedia
EME (communications) — Earth Moon Earth, also known as moon bounce, is a radio communications technique which relies on the propagation of radio waves from an earth based transmitter directed via reflection from the surface of the moon back to an earth based receiver.… … Wikipedia
