Question

Small scale propagation model is also known as _________

(a) Fading model

(b) Micro scale propagation model

(c) Okumura model

(d) Hata model

I had been asked this question in final exam.

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

Answer 1

The correct option is (a) Fading model

The explanation is: Small scale propagation model is also called fading model. Fading model characterize the rapid fluctuations of the received signal strength over very short distance of a few wavelengths or short time duration. The propagation models are used to estimate the performance of wireless channels.
