Hata model
open-in-new
<p> The Hata model is a <a href="/facts/Radio_propagation_model/80y1JV4M">radio propagation model</a> for predicting the <a href="/facts/Path_loss/I34lqCYk">path loss</a> of cellular transmissions in exterior environments, valid for <a href="/facts/Microwave/HmVSN31Y">microwave</a> frequencies from 150 to 1500 MHz. It is an empirical formulation based on the data from the <a href="/facts/Okumura_model/FyoNr3lC">Okumura model</a>, and is thus also commonly referred to as the Okumura–Hata model. The model incorporates the graphical information from Okumura model and develops it further to realize the effects of diffraction, reflection and scattering caused by city structures. Additionally, the Hata Model applies corrections for applications in suburban and rural environments. </p>
