Wireless Networks Assignment: Antenna, Multiplexing, Security and More

This assignment delves into various aspects of wireless networks, starting with an analysis of different antenna technologies, including Yagi, horn, and cellular antennas, evaluating their strengths and weaknesses, and predicting future trends. It further explores multiplexing techniques like CDMA and FDMA, comparing and contrasting their applications in wireless networking. The assignment also requires research into the latest wireless technologies, focusing on their practical applications and potential future dominance. It investigates security challenges in WPAN technologies and compares data encryption standards for WiMAX networks. Additionally, the assignment includes a critical review of research papers on energy harvesting in wireless communications. Finally, it presents a case study for Telestra, a telecommunications company, evaluating the advantages of using digital cellular handsets or cellular wireless cards for field service technicians, considering their ability to access and display standard PC documents, and creating a presentation suitable for both technical and non-technical audiences.

SUBJECT _WIRELESS NETWORKS
ASSIGNMENT 1
1.Different antenna, such as yagi, horn, and celluar antennas,
etc. has different merits. Research these technologies in details
and pay specific attention to how they are used as well their
strengths and weakness. Provide an opinion regarding which
antenna types will become the dominant players in the future of
medium- and long-distance wireless links.
2. Compare and contrast the multiplexing techniques CDMA
and FDMA in the area of wireless networking?
3. A local engineering group ask you to present your finding of
the most recent advanced wireless technologies. Research
these technologies in details and pay specific attention to how
they are used as well their strengths and weakness. Provide an
opinion regarding which antenna types will become the
dominant players in the future. Please submit power point
slides in your answer.
4. Compare and contrast three data encryption standards for WiMAX
networks?
5. Research the security challenges for any two examples of WPAN
technologies.
6. Read the following two research papers as follows, please give your
critical reflection on the topic of Energy Harvest.
Shaikh, Faisal Karim, and Sherali Zeadally. "Energy harvesting in
wireless sensor networks: A comprehensive review." Renewable and
Sustainable Energy Reviews 55 (2016): 1041-1054.
Ulukus, Sennur, et al. "Energy harvesting wireless communications:
A review of recent advances." IEEE Journal on Selected Areas in
Communications 33.3 (2015): 360-381.
7. Telestra is a company that is licensed to provide wired
telecommunication services in Australia. The company has contracted

Exetel to assist it with the selection and implementation of a new field
service system. The goal is to provide service technicians with wireless
access to the corporate network and a vast electronic library of technical
manuals and schematic diagrams, which would reduce or eliminate the
need for staff to carry a large number of books and drawings, especially
while servicing equipment underground or when climbing on
transmission towers. In addition, this means that the technicians would
be able to immediately read and update the records for all the
equipment, thereby avoiding massive amounts of paperwork as well as
potential errors and omissions. However, the company is having trouble
deciding on which technology to adopt- handheld cellular, tables with
3G/4G/5G access, or notebooks equipped with cellular cards. Exetel has
asked you to help.
-Create a presentation outlining the advantages for Telestra of using
digital cellular handsets or cellular wireless cards. Determine the
ability of the smaller cellular handsets (as opposed to notebook
computers, which may be difficult to carry everywhere) to display
standard PC documents such as Word, Excel, and PDF files, and
evaluate how this could help the company. Because the group you
will be presenting to is composed of nontechnical manager, be sure
your presentation is understandable by both technical and non-
technical personnel. Limit yourself to a maximum of 15 PowerPoint
slides.
