What factor does not influence the distance at which an RF signal can be effectively received?
What factor does not influence the distance at which an RF signal can be effectively received?
Receiving station's output power does not influence the distance at which an RF signal can be effectively received. The receiving station's radio sensitivity, transmitting station's output power, and free space path loss are all crucial factors that impact the effective receiving distance of an RF signal. The output power of the receiving station does not affect how far away it can receive signals; rather, it influences its transmission capabilities.
Should be B
Agree B makes more sense
This has to be B, because all other answers influence the distance.
B makes sense
Receiver sensitivity defines the minimum signal strength at which a data rate can be correctly received by a STA. RF sensitivity thresholds indicate lower limit of received power required to support operations. In WLANs, sensitivity thresholds indicate lower limit of received power required to support Dynamic Rate Shifting (DRS) levels and modulations.
B is correct
I too agree. If receiver sensitivity is not good, when signal is weak, receiver won't be able to pick the signal at all. So, I too think, it should be B.
B is correct
B makes more sense
B. Receiving station's output power CHAPTER 2 - PAGE 77 (Official Study Guide) --> This page tells us a little about it. The output power generated by the RECEIVING station does not interfere with the power it is receiving. FYI: "Free Space Path Loss (FSPL), [...] is a weakening of the RF signal due to a broadening of the wave front."
