(b) Effective received power and distance between T-R

(c) Gain and received power

(d) Effective transmitter power and receiver power

This question was addressed to me by my college director while I was bunking the class.

This question is from Free Space Propagation Model topic in portion Mobile Radio Propagation: Large – Scale Path Loss of Wireless/Mobile

Answer 1

Correct option is (d) Effective transmitter power and receiver power

Explanation: I Path loss is defined as difference of effective transmitter power and receiver power. Free-space path loss is the loss in signal strength of an electromagnetic wave that would result from a line-of-sight path through free space, with no obstacles nearby to cause reflection or diffraction.
