Assessment item 2: Task & Design Project                               

Task 1: Free Space Propagation and Path Loss

A complete MATLAB code that must calculate all the attributes like free space propagation, transmit power and free space path loss is submitted. The code will be in executable GNU Octave code with all the plots in a single word file. The code must contain the curves plotted in the form of output while running the code.


Task 2: Research Project

Solution 1:

In the solution, the capacity of the cell along with the base station’s locations are explained. All the areas i.e. urban, semi urban and rural will be explained in terms of the cell congestion. The cell splitting will tell the central business district location along with the boundaries and the height of the antenna. In the solution all the information will be covered such that base stations sites locations, antenna specifications like shape, size, height and gain. Nonetheless, the type of cell area will be considered representing the density of the traffic in Erlang.

Solution 2

From the solution 1, the user will depict the shape of the antenna which best fits and justifiable according to the given scenario. A complete reasoning will be explained along with the evidence of shape and justification regarding the shape of antenna which is used in representing the traffic density in Erlang.

Assessment 2 - Task and Design Project Task 1: Free Space Propagation and Path Loss (10%) In a free space wireless propagation en vironment, transmit power between a transmitter and receiver usually decreases due to free space path loss denoted as L(dB) and can be curves of the received power. You need to submit your executable GNU Octave code along with the plots in a single Word fi le. Task 2: Research Project (10%) 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 i nformation 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 th e numbers within each cell are representing the traffic density in Erlang. (8 marks) 2. Looking at the Figure 1 below, justify the design of this cellular network with appropriate reasoning? (2 marks) Rationale This assessment task will assess the followi ng 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 an d contrast different wireless networks in terms of size, speed, limitations and applications.
