CDTask 1 Q2: FreV§iPAG’PASVagation and PathLoss (7%)In a free space wireless propagation environment, transmit power between a transmitter and receiver usually decreases due to free space path loss denoted as L f (dB) and can be expressed as a function of distance d between the transmitter and receiver. Your task is to calculate and plot the path loss L 1 (dB) for a distance d = 0 to 30 km and carrier frequency f c = 100, 500 and 1000 MHz. Assuming that the transmit power Pt is 40 watts, you can calculate and plot the received power Pr as a function of distance d (as given above) for the carrier frequencies given above. You can assume transmit and receive antennas gains are the same, i.e. Gt = Gr = 0 dB .Deliverable: You are required to plot path loss Lf (dB) as a function of distance for each carrier frequency, so you will have three curves in the plot. You also need to plot received power Pr as a function of distance d for each carrier frequency, so you will have three curves of the received power. You need to submit your executable GNU Octave code along with the plots in a single Word file.Task 2: Research Project (8%) You are working as Network Design Engineer with local service provider and your manager has asked you to proposethe d,,,;E,,, — lli,L, ‘../vv ,,llular
