line-of-sight path
1Line-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… …
2line of sight — n. 1. an imaginary straight line joining the center of the eye of the observer with the object viewed 2. Radio TV the straight path from a transmitting antenna to the horizon, representing the normal range of high frequency wave propagation: Also …
3line of sight — noun an imaginary straight line along which an observer looks • Syn: ↑line of vision • Hypernyms: ↑line * * * 1. or line of sighting : a linear projection toward a target of the straight line obtained when the sights of a firearm are in perfect… …
4line of sight — i. The straight line between two points. This line is in the plane of the great circle but does not follow the contour of the earth. Radar and some forms of radio waves are capable of being received in the line of sight. ii. The straight line… …
5line-of-sight reception — A characteristic of high frequency radio signal transmissions that requires a clear path between the transmitter and the receiver. Typical line of sight reception ranges are indicated in the illustration. See also direct wave. Typical line of… …
6line-of-sight — An unobstructed path between the transmitter and receiver. Laser, microwave, and infrared transmissions usually require a clear line of sight. See also wireless communications …
7line of sight — 1. Also called line of sighting. an imaginary straight line running through the aligned sights of a firearm, surveying equipment, etc. 2. Astron. an imaginary line from an observer to a celestial body, coincident with the path traveled by light… …

10Non-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… …
