Question

what is Matlab code to plot the path loss from 0 to 10 km using Hata model, assuming fc= 900 MHz in an urban environment, mobile antenna height is 1.5 m, and base station antenna height are 30 and 200 meter, respectively.

Answer 1

MATLAB CODE:

clc
clear all
close all

d = 0:0.001:10; % Distance between mobile and base stations in Kilometer
hM = 1.5; % Mobile Station antenna height in meteres

hB = 30; % Base Station antenna height in meteres
hB1 = 200; % Base Station antenna height in meteres

f = 900; % Frequency of Transmission in MHz
CH = 3.2*(log10(11.75*hM))^(2) - 4.97;
% Path Loss
PL = 69.55 + 26.16*log10(f) - 13.82*log10(hB) - CH + (44.9 - 6.55*log10(hB))*log10(d);
PL1 = 69.55 + 26.16*log10(f) - 13.82*log10(hB1) - CH + (44.9 - 6.55*log10(hB1))*log10(d);

plot(d,PL)
xlabel('Distance d (Km)')
ylabel('Path Loss (dB)')
% title('Path Loss for hB = 30 m')
grid on

hold on

plot(d,PL1)
xlabel('Distance d (Km)')
ylabel('Path Loss (dB)')
grid on

legend('Path Loss in dB for hB = 30 m','Path Loss in dB for hB = 200 m')

OUTPUT:
