Question

The propagation model that estimates radio coverage of a transmitter is called ___________

(a) Large scale propagation model

(b) Small scale propagation model

(c) Fading model

(d) Okumura model

The question was posed to me during an interview for a job.

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

Answer 1

The correct option is (a) Large scale propagation model

The best explanation: Large scale propagation model are useful in estimating the radio coverage area of a transmitter. They can predict the mean signal strength for an arbitrary transmitter-receiver (T-R) separation distance. They characterize signal strength over large T-R separation distances.
