Question 2: Free Space Propagation and Path LossFree Space Path LossThe formula for the calculation of the Free Space Path Loss is given as follows,Path Loss (PL) = 32.45 + (20*log10 (frequency)) + (20*log10 (distance));4.Calculation for frequency 1Frequency = 100 MHz, Distance = 10 kmPL1 = 32.45 + (20*log10 (100)) + (20*log10 (10));= 92.455.Calculation for frequency 2Frequency = 500 MHz, Distance = 20PL1 = 32.45 + (20*log10 (500)) + (20*log10 (20));= 112.456.Calculation for frequency 3Frequency = 1000 MHz, Distance = 30 kmPL1 = 32.45 + (20*log10 (1000)) + (20*log10 (30));= 121.99Free Space Path Loss Codeclc;% To clear the screenclear all;% To clear the past dataclose all;% To close the past functions6
