8227 Wireless Networks Final Examination

On March 11th 2020, the World Health Organisation (WHO) declared COVID-19 a pandemic as the number of global infections continued to rise. Since then, governments throughout the world have enforced strict social distancing policies to prevent the spread of the virus, bringing many industries to a standstill. At the time of writing, nearly half of the global population is on some form of lockdown, with millions of people being encouraged to stay indoors and work from home where possible. 

As a result, we’re seeing demand moving away from cellular networks and onto home Wi-Fi networks in an unprecedented way. It represents a huge shift in consumer behaviour that could never have been predicted and presents a great challenge to home broadband providers. However, new challenges also present new opportunities, and the Wireless Broadband Alliance (WBA) and its members are working hard to ensure that Wi-Fi technology steps up and delivers. 

That means the pressure is now on the wireless industry to deliver fast and dependable worldwide connectivity at a time when self-isolation and quarantine are becoming the norm. Following are some strategies identified by the WBA as possible solutions:

1. OpenRoaming 
2. Wi-Fi 6
3. Wi-Fi 6E

Task    :           Your task is to design a solution for the aforementioned problem using the proposed strategies. You need to justify how your solution can deliver a more stable and dependable broadband service and solve the connectivity problems of a home network, enabling seamless and secure Wi-Fi roaming.  You have complete freedom to design a solution to improve the capacity of a home Wi-Fi network. Remember, less is more: simple solutions are the best solutions.

Method :         You must familiarize yourself with the current literature published under the above topic. Therefore, you must first perform a literature survey. Publications can be accessed via UC Library’s A-Z Databases.  A recommended database for this task is IEEE Xplore. If you have difficulties in remotely accessing the UC Library databases, please contact the library and they will be able to help you. If you are unable to access UC Library databases as recommended, Google Scholar may be an alternative option. However, not all documents from Google Scholar can be considered as peer-reviewed publications from legitimate sources. Next, you may proceed with the designing of your novel architecture.      

Format :          The final report must be prepared according to the guidelines of the attached template. It must have an approximate word count of 1100 (excluding references) and reference up to 8-10 peer-reviewed publications (preferably from 2010 onwards). IEEE referencing format must be followed.

Due      :           1.00 pm, Monday, 25 May (Week 16)
