Hata Path loss model

pMSnp.array: Mobile position (meters)
pBSnp.array: Base station position (meters)

fGHz : np.array hMS : height mobile station (m) hBS : height base station (m) typ : ‘small’ or ‘big’

L : Attenuation (dB)

>>> d = np.linspace(100,5000,120)
>>> hBS = 30
>>> hMS = 1.5
>>> fGHz = 0.9
>>> pMS = np.array([d,0,hMS])
>>> pBS = np.array([d,0,hBS])
>>> L = hata(pMS,pBS,fGHz,hMS,hBS,'small')

This model is valid until 1.5GHz, for higher frequency see COST231-Hata model
