NEW QUESTION # 43
As an RF signal propagates it becomes weaker as it gets farther away from the transmitter. What concept is described?
- A. Free Space Path Loss
- B. RF latency
- C. Diffraction
- D. Beamwidth
Answer: A
Explanation:
The concept described is Free Space Path Loss (FSPL). FSPL refers to the reduction in power density of an electromagnetic wave as it propagates through a clear, unobstructed path in free space. This weakening of the signal is due to the spreading of the wavefront as it travels, causing the power to be distributed over a larger area. The FSPL can be calculated using the Friis Transmission Equation, which shows that the received power decreases with the square of the distance from the transmitter. This concept is fundamental to understanding the behavior of RF signals in various communication systems, including wireless IoT, where the signal strength at the receiver is a critical factor for reliable data transmission.
References:The information provided aligns with the Friis Transmission Equation, which models how the power of an RF signal decreases with distance1. Additionally, the concept of FSPL is a well-known phenomenon in RF propagation, affecting the design and optimization of wireless communication systems
