MITS5003 Wireless Networks and Communication - Victorian Institute of Technology

Assessment 1: Case Study and Presentation

Introduction

In this assessment you are required to explore the given case study and provide a solution, employing the latest wireless communication techniques. The solution needs to be presented in a report and a short video presentation discussing findings and the proposed solution. The assessment will help in developing an understanding of communication in wireless networks and the limitations and challenges.

Case Study: Home office
Under doctor's orders for more bed rest, Jan received authorization from her employer to work from home during and immediately after her pregnancy. However, to do her job effectively, she routinely needs to retrieve large files from the corporate local area network (LAN), modify them, and return them to another location on the LAN. She also occasionally likes to print something for convenience or record keeping, and she needs convenient access to a telephone. Jan has received instructions from her company's Information Technology (IT) staff regarding how to connect to the corporate LAN.

Jan currently has broadband access to her home. However, the only access is to a PC in a family room in the home's finished basement. Jan's family uses this PC for Internet access, online gaming, and as a resource for school projects. The PC is connected to a colour printer. Jan wants to create a home office in an unused upstairs bedroom. During the later stages of her pregnancy, she wants the convenience of working from more comfortable locations, such as her couch or bed. She already has a cordless phone and is planning to purchase a laptop PC and perhaps a second printer. However, a quick call to her broadband provider has caused her to question the financial feasibility of running new wiring for broadband access in other locations of her home. Perplexed with her problem, Jan talks to some of her co-workers, and one of them mentions wireless. Jan does a little investigation of the wireless LAN products available and decides many of the products are within her budget.

The scope of Jan's solution will be limited by the fact that she already has broadband access installed in her home. She also has instructions for connecting to the corporate LAN. However, she has not checked to see if the wireless home network will affect these instructions. Jan's challenge is that she needs reliable high-speed access to the corporate LAN from the new home office and other convenient locations in the house. She wants to interfere as little as possible with use of the PC in the family room, and she needs her laptop to be inaccessible from the family PC. She would like to have printing capability in the home office. However, her solution must fit within a limited budget. Finally, all equipment that she uses for her solution must be immediately available.

Figure 1. Jan's Site

The proposed solution must consider the following requirements:
• Any locations where she wants to use the laptop should not be more than 100 meters (over 300 feet) away from the access point
• Interference which may be caused by the cordless phone and microwave
• The home network should be cost efficient
• The network needs to be secure
• Other users on the home network

Assessment 2: Research Report

Introduction
In this assessment students are required to research on an article in the area of wireless communication. The research needs to be geared towards the transmission fundamentals with focus on the wireless channels, analysing the performance of wireless networks. The assessment is aimed to improve the student's investigation and analysis skills.

Task
In this assessment you are required to prepare a 2-page abstract in IEEE Style, use the template provided on the LMS. To prepare the abstract you need to select an article published in 2015 and later. The selected article needs to include wireless transmission fundamentals. The article needs to be on one of the areas given below.
• 4G and 5G cellular systems
• Ad hoc wireless networks
• Adaptive antennas for wireless systems
• AI Powered Wireless Communications
• Channel estimation
• Computation and Data Driven Wireless Communications
• Heterogeneous cellular networks
• Next generation WiFi
• Massive MIMO
• Propagation and channel characterization

The report must follow the template provided on the LMS. Please note that citation of sources is mandatory and must be in the IEEE style.

Assessment 3: Major Assignment

Introduction
In this assessment the students are required to plan and design a wireless enterprise network for a hospital. To design the enterprise network, you are required to perform requirement analysis, understand the site, including the infrastructure and any line of sight issues. Since the buildings are medical in nature, you must take special care when deploying wireless communications. Medical equipment may be sensitive to wireless devices and channels. You must pay special attention to limiting radio frequencies in and around the emergency room area to avoid any interference

Task

The IS manager from Jones Hospital has hired you as a consultant to provide a wireless LAN solution for their hospital network. The hospital employs just over 800 employees, working in a complex composed of seven buildings in an urban area. All the buildings are close enough in proximity that employees frequently walk between buildings. The management staff wants to deploy wireless technology in their enterprise network. They have heard that this type of network will save them money as opposed to the current leased line network. They believe that the added mobility will also dramatically increase productivity. Since the staff moves from building to building, it seems to be the right idea to provide them with computer equipment and data that will roam with them. The area that the hospital buildings cover is shown in the Figure 2.
