Question

What does path loss exponent indicates?

(a) Rate at which path loss decreases with distance

(b) Rate at which path loss increases with distance

(c) Rate at which path loss decreases with power density

(d) Rate at which path loss increases with power density

This question was posed to me in an internship interview.

My enquiry is from Practical Link Budget Design Using Path Loss Models topic in portion Mobile Radio Propagation: Large – Scale Path Loss of Wireless/Mobile

Answer 1

Correct choice is (b) Rate at which path loss increases with distance

The explanation is: The average large scale path loss for an arbitrary T-R separation is expressed as a function of distance by using a path loss exponent, n. It indicates the rate at which the path loss increases with distance.
