CWISA-103 · Question #58
As an RF signal propagates it becomes weaker at any given measurement point as it gets farther away from the transmitter. What concept is described?
The correct answer is B. Free Space Path Loss. Free Space Path Loss (FSPL): Describes how a radio signal weakens as it travels through open space, even without obstacles. It's caused by the signal spreading out, resulting in decreased power density at the receiver. Calculation: FSPL depends on distance and frequency.
