Fuzzy logic was applied as a set of rules to characterize precisely the unknown propagation environment from a set of known propagation environments. As a result, more cost-effective cellular network designs are expected using the path method. WebHATA MODEL AND RECEIVER NOISE COMPUTATION - YouTube. This video lecture deals with the explanation of Hata Propagation model for path loss calculation.
The Hata model is a radio propagation model for predicting the path loss of cellular transmissions in exterior environments, valid for microwave frequencies from 150 to 1500 MHz. It is an empirical formulation based on the data from the Okumura model, and is thus also commonly referred to as the … See more Though based on the Okumura model, the Hata model does not provide coverage to the whole range of frequencies covered by Okumura model.
