Empirical path loss formula:

A(dB)=46.3+39.9Log(F)-13.82 Log(H1) -a (H2)+(44.9-6.55 Log(H)) Log(D)-C

where:

A=Path loss in dB

F= Frequency in Mhz (1500~2000 MHz)

D=Distance between base station and terminal in km (1~20 km)

H1 =Effective height of base station antenna in m (30~200 m)

H2=Effective height of mobile station antenna in m (1~10 m)

a (H2)=the correction factor for effective mobile antenna which is function of the size of the coverage area

C=Environment correction factor

= 2 dB for dense urban environment (buildings greater than 7 floors, medium and small streets)

= 5 dB for medium urban environment (medium buildings of 5 floors, medium and small streets)

= 8 dB for medium urban environment and wide streets

= 10 dB for suburban environment with small buildings

= 20 dB for mixed rural and villages

= 23 dB for rural with a few trees and quasi no hills
