Objective:
- I can demonstrate my understanding of computer networks, network operating systems and wireless networking by assembling a directional antenna with the intent of establishing and sustaining a 2.4 GHz wireless signal at a distance of greater than 100 yards.

Assignment:
Today, we are going to begin a focused short-term project in preparation for our broader long-term project following Spring Break. The goal is simple: design and build a directional antenna that will sustain a 2.4 GHz Wi-Fi signal over a minimum distance of 100 yards (300 ft or ~92m).
The stretch goal is a little more complex: design and build a directional antenna that will extend that 2.4 GHz Wi-Fi signal as far as possible.
- Use the links I have provided to learn about do-it-yourself directional antenna designs. There are many designs to choose from, so do your research and select the design that you think will be most effective in extending and sustaining the Wi-Fi signal over the longest range.
- You may work with a partner, or choose to go it alone. If you choose to work with a partner, you will need to pick up and complete both a Project Team Contract and a Project Team Work Plan (available in the Student Pickup Folder in the Marmolejo NetOp 1-2 subfolder on the StudentsTempFiles network share).
- Even if you are working by yourself, use the Project Team Work Plan to identify and prepare for the steps of this project (i.e. research, acquisition of materials, installation, configuration, building, testing, modification and upgrades). Submit a completed Project Team Work Plan to the instructor as soon as it is completed.
- Proceed with the first identified steps in your Project Team Work Plan. Do your best to follow the plan, but don’t be afraid to amend or alter the plan as the need arises.
- You may work in Room 225, but you will need to notify the instructor if you need access the tools in Room 212.
- All tools and equipment are located in Room 212. The wireless network cards are located in the cabinet closest to the Teacher Workroom door in Room 212. You will need to request a wireless network card when you are ready to install it in your PC. (We only have four 802.11g network cards, so you will need to share unless you are willing to provide your own).
- Please use this time to make progress on your project. We have time provided to complete the project, but no time to waste. It is highly likely that your first antenna design may not be your final design, and you will need time to test and make adjustments to your design to achieve optimal results. Use the time given to build, test, modify and retest to get the best results!
- We will conduct initial tests the week of February 6th. To be considered a success (and receive credit for the project), your antenna design must be able to sustain at least a one-bar wireless signal over a 100 yard distance (the length of the football field).
- Upon completion of initial tests, you will have a week to revise and retest your design before the final testing during the week of February 20th.
- The team (or individual) that produces the antenna that can reliably sustain the highest gain signal over the longest distance on the final testing day will receive a personal pizza and wings party, to be held while everyone else writes a four paragraph personal reflection describing their participation in this project.
Good luck, and remember: the best way to eat an elephant is one bite at a time.
