TASK
This assignment has three components; there are two task 1 and task that you need to complete and submit via Turnitin. There will be a viva type questions answer with your lecturer face to face in the class. This part will carry 5% weightage of the assignment
Task 1: Free Space Propagation and Path Loss (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 Lf (dB) and can be expressed as a function of distance d between transmitter and receiver. Your task is calculate
and plot the path loss Lf (dB) for a distance d = 0 to 20 km and carrier frequency f c =
100, 300 and 1000 MHz. Assuming that the transmit power Pt is 50 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%)
1. You are working as Network Design Engineer with local service provider and your manager has asked you to propose the design for the below cellular architecture shown in Figure 1. In your design provide the following information with reasons; Base station sites locations, Antenna specification (such as antenna shape, height, gains etc), mention the type of the area considering the cell size (such as suburban, metropolitan, rural etc) and justify you design. Note that the numbers within each cell

are representing the traffic density in Erlang. (6 marks)
2. Looking at the Figure 1 below, justify the design of this cellular network with
appropriate reasoning? (2 marks)

Task 3: Face to Face viva questions (5%)
Your lecturer will take viva from Task 1 and Task 2 in the class after the due date of the assignment. Viva's will be be conducted between 27th April to 8th May, please make an appointment with your lecturer. If you fail to give the viva between the above mentioned dates you may get zero mark for Task 3.
RATIONALE
This assessment task will assess the following learning outcome/s:
be able to critically analyse wireless networking concepts and their applications in real life situations.
be able to analyse and describe wireless signalling techniques and radio frequency communications.
be able to compare and contrast different wireless networks in terms of size, speed, limitations and applications.
