Task and Design Project
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 (dB) and can be expressed as a function of distance between transmitter and receiver. Your task is calculate and plot the path loss (dB) for a distance and carrier frequency = 150, 400 and 1000 MHz. Assuming that the transmit power is 100 watts, you can calculate and plot the received power as a function of distance (as given above) for the carrier frequencies given above. You can assume transmit and receive antennas gains are the same, i.e. .
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 1 below, justify the design of this cellular network with appropriate reasoning?

Assessment 3 - Task and Research Project
Task 1: Microwave Link Budget Design
Microwave communication is commonly used as a backbone transmission system in wireless communication networks. As a wireless network engineer, you are often required to perform link budget calculations for such Microwave links. One such link is shown below in Figure 1 which operates in the 20 GHz radio frequency band. This link provides 4 Mbps transmission capacity at both transmitter and receiver sides. Furthermore, the system deploys a passive repeater. Following table shows numerical values for this transmission system.

1. Calculate the nominal Receive Signal Level (RSL) at the input of the receiver in dBm assuming free space conditions.
2. Briefly discuss the purpose of the passive repeater in this system?
Task 2: Innovative Research Project
A local engineering group ask you to present your finding of the most recent advanced wireless technologies such as 5G and millimeter Wave (mmWave) communication for future generation wireless communication. Research these technologies in details and pay specific attention to (one of them) and discuss how they are used, their application in real life, their strengths and weakness and security issues. You need to provide at least three recent reference articles to your technology of choice. Also provide an opinion regarding which antenna types will become the dominant players in the future such as you may consider physical antenna structures or antenna related signal processing such as multiple-input multiple-output (MIMO) techniques etc.
Deliverable: You need to provide a report on your selected wireless communication technology. The report should include Abstract, Introduction, Body of the report that may include sections such as real life applications, advantages and challenges, security issues etc (body of the report vary for each student), conclusion and references. Your report should not be more than four A4 pages long including everything, i.e. from first page to the last page of references. In general, four A4 pages with the font size of 11 may have 2000 words (maximum). The report has 6% of the total task 2 weight-age.
You are also required to give a short upto 10 minutes oral presentation during the online meeting or in the class. Your lecturer will schedule time for your oral presentation. Your presentation should have maximum 10-12 slides. The presentation has 4% of the total task 2 weight-age.
