Detailed explanation-1: -Full Line of Sight (LOS) is where no obstacles reside between the two antennas. Near Line of Sight (nLOS) includes partial obstructions such as tree tops between the two antennas. Lastly, Non Line of Sight (NLOS) is where full obstructions exist between the two antennas.
Detailed explanation-2: -Line of sight (LOS) is the imaginary line between an observer and the target. In communication, line of sight is the direct path from a transmitter to the receiver and the obstructions that may fall in that path. A clear line of sight is important to high-speed communication.
Detailed explanation-3: -Hint: There are three types of modes of propagation of electromagnetic waves: Ground wave propagation, Space wave propagation and Skywave propagation.
Detailed explanation-4: -Line-of-Sight (LoS) propagation is a characteristic of electromagnetic radiation in which two stations can only transmit and receive data signals when they’re in direct view of each other with no obstacles in between. Satellite and microwave transmission are two common examples of LoS communication.
