Mini Assignment: Measure your WiFi Network's Performance
UPDATES
Fri Sep 18 14:13:11 EDT 2020: Presentations will be limited to a
maximum of 5 minutes each.
This assignment is meant to help you understand some of the issues you might face when conducting an experiment and to motivate some of the problems we'll explore in this class.
- Conduct experiments in which you try to obtain the maximum possible throughput from your WiFi network.
- To try to determine the maximum speed (throughput) you are able to obtain when connected to the network. Please report all speeds in Mbps (megabits per second) where 1 megabit is 1,000,000 bits (not 1024 * 1024 bits).
- This is not meant to be an exhaustive study. The purpose is to get you to run some experiments and to start thinking about and exploring some of the issues that will be discussed in this class.
- Please work individually as much as possible as there will be more to learn from a diverse set of experiments than if everyone ends up conducting the same experiments. It will also make the presentations more interesting.
- Create a presentation that will be given in the next class.
Logistics
It is critical that you follow these instructions carefully. With lots of students in the class the overhead of dealing with people who don't follow the instructions is too high to cope with.
- Send me the PDF as an email attachment prior to the deadline in the course schedule.
-
Your filename must be all lower case and contain (in order)
your given name, a dash, and the first letter of your family name.
For example, my filename would be tim-b.pdf
Send the file as an attachment using the following subject line:
Subject: 854 Assignment - I will have all presentations available for sharing on my system to prevent problems and timing delays with change overs between presentations. I will may end up showing/running the slides and having you tell me when to advance the slides.
Assignment Presentation
- Presentations will be done live during the online class.
- They will be roughly max(7,120/N) minutes each (where N is the number of presentations).
- They MUST BE DONE IN POINT FORM
- You MUST email me the PDF (follow the instructions carefully).
-
All presentations must have a least one slide containing each of
the 5 headings below.
The bullet points outlined below each heading are meant to
provide you with some guidance. You must be sure
to include these as a minimum but also feel free to
include other important issues/aspects.
- Environment
- What hardware and software was used?
- Methodology
- What is the metric of performance?
- What experiments did you conduct and why?
- How were the experiments performed?
- Findings
- What results did you get?
- Issues Faced / Lessons Learned
- Outstanding Questions / Problems
- Environment
Some Tips for Giving Your Talk
- Use large fonts
- Don't include info unless you can use it.
- Figure out how long it takes you to give your talk
- Plan what you want to say in your M minutes (e.g., what is your main point)
- Eliminate anything extra
- Use bullet points / point form only
No sentences
If you have lots of text, the readers will begin reading the long text to see what it says and by the time they are finished reading it you will have lost them. In fact they may not be done reading the slide by the time you have moved onto the next slide and then they will be lost. They are also likely get bored just like what is happening now when you are reading all of this text :-) - You want the audience listening to you and not reading the slides!
- Proof read your slides.
- Number the slides so if there are questions they can be referred to by number.
- You don't need to report on / explain all experiment you run
- Don't use default or create large headers (it wastes lots of valuable slide space)
