ITC542 Wireless Communication: Practical Tasks and Code Solutions

This assignment solution addresses practical tasks related to wireless communication, including listing advantages and limitations of wireless networks compared to wired networks. It also includes Octave code for signal generation and analysis, demonstrating the student's ability to apply programming skills to communication systems. Furthermore, the solution incorporates screen shots and reflections from Acrylic Wi-Fi Home projects, analyzing wireless network signal strength and the impact of obstacles and human interference. The document provides a comprehensive overview of wireless communication concepts, practical application, and signal analysis techniques.

Wireless Communication:
Solution 1:
Advantages that wireless communication has over wired networks :
 The network can be accessed by a user at any point lying in the range of the network.
 The sharing of files is easy in wireless communication as no cable is required.
 The system is simple and tidy which makes it less complex. The customer prefers
wireless network due to the ease of use which helps to enhance the business and income
levels.
Limitations / challenges that wireless communication has over wired networks :
 Upgradation to a wireless network is costly as well as difficulty is more as per Zeine, H.
(2015).
 Speed of file transfer or sharing is lower.
Security is less as the data can be accessed in the bandwidth specified as per Holfeld (2016).

Solution 2:
Octave Code:
clc
a = 1;
pi = 3.14;
f1 = 2;
f2 = 2 * f1;
t = [0:0.01:50];
y1 = a * (sin (2*pi*f1*t));
subplot (1,2,1);
plot(t,y1);
xlabel('Time(sec)');
ylabel('Amplitude');
t = [0:0.01:50];
y2 = a * (sin (2*pi*f2*t));
subplot (1,2,2);
plot(t,y2);
xlabel('Time(sec)');
ylabel('Amplitude');

Reflections for Project 3-4

 I learnt how to find the wireless networks in the area around my current location.
 I learnt how to know the SSID of my wireless network.
 I learnt how to find the rating of various control parameters of my wireless network in
comparison to other networks.
Reflections for Project 3-5
 I learnt that the Wi–Fi signal strength decreases as the distance of computer from AP
increases and it is strong up to a certain range.
 I learnt that the Wi-Fi signal strength decreases if an obstacle comes between the
computer and the AP.
 I learnt that the human hand can also lead to a reduction of Wi-Fi signal strength.
