Line of Sight

Line of Sight (LOS) refers to the direct, unobstructed path between two points, typically used in communication or vision. In wireless communication, LOS means a clear path between a transmitter and receiver without physical barriers like buildings or terrain blocking the signal. This unobstructed line ensures better signal quality and faster data transfer. LOS is essential in technologies such as satellite links, radar, and certain radio communications, where visibility or an unblocked path maximizes performance and reliability. If obstacles interfere, the connection can weaken or break, requiring alternative methods or equipment.
