Okumura is based on measurement. Hata model is an empirical formulation of the graphical path loss data provided by Okumura.. I think for basics, refer to book Wireless communication, by Theodore Rappaport

Important point for path loss simulation is your simulation environment. location, frequency, antenna gain, transmit power, receive power,... you have to cosider various factor. ex) free path loss model. Pr = (lamda/(4 * pi*distance))^2 *Gr * Pt * Gt Pr : receive power lamda : wave length Gr : receive antenna gain Pt : transmit power Gt : trnasmit antenna gain

Can u plz help me out. regards sohkha
