Line of Sight (LOS) communication describes a path where the signal travels without obstructions.

Line of Sight (LOS) communication describes a path where the signal travels without obstructions.

• A. TRUE
• B. FALSE
• C. Not applicable
• D. Do not know

Answer: (A)

Line-of-sight communication means the signal travels along a direct, unobstructed path between transmitter and receiver. That’s why this statement is true—the defining feature of LOS is an unobstructed path. Obstructions like buildings, trees, or terrain block or weaken the signal, which is why maintaining a clear path is essential for reliable control and video links in drone operations. When obstacles are present, the path is no longer true LOS and the link quality suffers; reflections or diffraction can occur but are not considered LOS paths. The other options don’t fit because they imply uncertainty or describe a condition that isn’t about having a clear, unobstructed path.
