Assessment - Tasks and Design Project

TASK
This assessment has three components; there are two tasks that you need to complete and submit via Turnitin. Task 3 is a question & answer session with your lecturer in class or online meeting.

Task 1: Free Space Propagation and Path Loss
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 the transmitter and receiver. Your task is to calculate and plot the path loss Lf (dB) for a distance d = 0 to 30km and carrier frequency fc = 200, 500 and 1500 MHz. Assuming that the transmit power Pt is 100 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.

Task 2: Research Project

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.

2. Looking at the figure below, justify the design of this cellular network with appropriate reasoning?

Task 3: Viva Questions
Your lecturer will ask questions from Task 1 and Task 2 in the class or online meetings after the due date of the assignment. Viva will be conducted between 7th and 20th September. Please make an appointment with your lecturer. If you fail to give the viva between the abovementioned dates you may get zero marks 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.
