In some rules systems, one unit is considered to be able to see another if it can establish a clear Line of Sight. Such a LOS is simply a straight line from one unit to the other, unblocked by terrain or objects that cannot be "seen through" according to the rules. For instance, trees or a hill might block a LOS.
also radio line of sight—the visible, unobstructed path required to enable radio communications between two distinct access points., mega—an abbreviation for the value one million; since computers use the binary number system instead of decimal, the actual value represented is 1,048,576.
Verbal magic and abilities require that the target be visible to the caster upon completion of the incantation. If the target of the verbal magic or ability is wholly hidden outside of the casters view, such as short sword completely hidden behind a shield, then the magic or ability will be expended without affecting the target. If the caster can see a portion of the target, no matter how small, upon completion of the incantation, the spell will affect the target as normal. Thornwall and Wall of Force block line of sight.
A clear line from one antenna to another in a long-range wireless network line of sight is necessary for a long-range network to connect.
Straight line from a radar antenna to a target.
Characteristic of certain transmission systems such as laser, microwave, and infrared systems in which no obstructions in a direct path between transmitter and receiver can exist.
wireless transmission that requires unobstructed path between the source and receiver. Infrared remote control for TV is a common example, but a variety of wireless communication services also require line of sight access to satellites or transmission towers.
A good "line of sight" doesn't necessarily mean you can see one of the WiFi Nodes, but there should be a minimum of trees and other "light" obstructions. Buildings and of course, sand dunes are "heavy" obstructions and reduce the WiFi signal dramatically. With a good "line of sight" the WiFi signal can be accessed with a minimal cost "directional" antenna for well over a mile, perhaps two miles or more, under "good" conditions. Virtual Private Network (VPN): Refers to a network in which some of the parts are connected using the public Internet, but the data sent across the Internet is encrypted, so the entire network is virtually private. A typical example would be a company network where there are two offices in different cities. Using the Internet the two offices merge their networks into one network, but encrypt traffic that uses the Internet link.
An unobstructed path between sending and receiving antennas.
Network communication systems that require a direct, unblocked path to transmit data.
A clear, unobstructed view of some remote point.
an imaginary line which passes through the sights
an imaginary straight line along which an observer looks
In line of sight transmission the transmitting and receiving stations (antennas) can see each other. It's a clear path between transmitting and receiving stations.
Aka eyeball shot. For terrestrial microwave links; where two radio transceivers with dish antennas point directly to each other, capable of carrying a multitude of different bandwidths depending on size of the dish/antenna, weather, and power emitted - up to about 50 miles between dishes.
The microwave signal transmission path must be free of obstacles such as mountains or buildings to avoid signal degregation.
The connection between communication devices of certain types (i.e. infrared) in which no obstructions on a direct path between transmitter and receiver may exist.
Direction from which an outdoor media structure can be viewed. A given structure may have more than one line-of-sight.
An unobstructed view between a base station and a radio/antenna unit.
A description of an unobstructed radio path or link between the transmitting and receiving antennas of a communications system.
The “line of sight” in SSI terms simply describes the process to link your occupational/skills shortages with their root causes and their solutions. Keeping this entire process in your “line of sight” is another way of saying you must keep your eyes on the “big picture” and make sure every part of your initiative fits clearly within that picture.
High frequency RF (1GHz) does not transmit through solid objects. The transmitter must "see" the receiver in order to complete the path. On very long shots (30 miles), the curvature of the Earth can become a factor.
The maximum unobstructed distance between transmitter and receiver which produces an adequate signal.
An unobstructed view from one location to another that is used to send a video signal wirelessly between two locations.
Unobstructed path between antennas. Essential for very high frequency WLL to operate.
(Or line of sight path.) An unimpeded path between two points in the atmosphere determined by the trajectory of a ray between them. Sometimes synonymous with optical path, a term that may, however, be a shortened form of optical pathlength, which is not the same as line of sight.
(n) Imaginary rays of light radiating from an observer's eye to the object. In perspective projection, all lines of sight start at a single point; in parallel projection, all lines of sight are parallel. LOS is sometimes referred to as the viewpoint.
The straight line through the sights of a gun to the point of aim.
The transmission path of a wave that travels directly from the transmitting antenna to the receiving antenna. Also called LOS.
Of an electromagnetic wave, propagation in which the direct ray from the transmitter to the receiver is unobstructed, i.e., the transmission path is not established by or dependent upon reflection or diffraction.
An unobstructed radio path between a radio's transmitter and receiver antennas.
(1) A characteristic of some open-air transmission technologies (such as microwave, infrared, and open-air laser-type transmissions) in which the path between a transmitter and a receiver must be clear and unobstructed . (2) A clear, open-air, direct transmission path that is free of obstructions such as buildings but may in some cases be impeded by adverse weather or environmental conditions.
Line of sight, sometimes written line-of-sight, is a term used in wargames and some role-playing games. It refers to visibility (that is, who can see what) on the playing field.
