Question

The Hata model is empirical formulation of which model?

(a) Okumura model

(b) Longley- Rice model

(c) Durkin’s model

(d) Walfisch and Bertoni model

I had been asked this question in examination.

My question comes from Outdoor Propagation Models in section Mobile Radio Propagation: Large – Scale Path Loss of Wireless/Mobile

Answer 1

The correct choice is (a) Okumura model

The best explanation: The Hata model is an empirical formulation of the graphical path loss data provided by Okumura. It is valid from 150 MHz to 1500 MHz. Hata presented the urban area propagation loss as a standard formulation. It supplied correct Equations for application to other situations.
