  • 802.11 Wi-Fi spec
  • Directional Antennas
  • Waveguide Antenna
  • Yagi Antenna
  • Flickenger design Antenna

Assignment:

Today, we are going to begin a focused short-term project that is to be completed before the Christmas 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.

  1. 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.
  2. You may work with a partner, or choose to go it alone. If you choose to work with a partner, you will need to download, complete and turn in both a Project Team Agreement and a Project Team Work Plan (available via the links provided above).
  3. 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).
  4. Upload your completed Project Team Agreement Form and Project Team Work Plan Form to today’s assignment post on our Google Classroom as soon as they are completed. The completed Project Team Contract and Project Team Work Plan are due by the end of the class on Wednesday, December 6th.
  5. 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.
  6. Tools and equipment will be provided, and all work should be completed in Room 225. You will need to notify the instructor if you need access to any additional tools located in Room 212. Testing PCs (sender and recipient) will be provided on rolling carts to allow for testing of antennas.
  7. 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 will not work as well as you expect it to, 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!
  8. We will conduct initial tests the week of December 11th. To be considered a success (and receive credit for the project), your antenna design must be able to sustain at least a -67 dBm wireless signal over a 100 yard distance (the length of the football field).
  9. Upon completion of initial tests, you will have a week to revise and retest your design before the final testing on Monday, December 19th.
  10. The team (or individual) that produces the antenna that can reliably sustain the highest signal strength 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 three paragraph personal reflection on Wednesday, December 20th describing their participation in this project.

Good luck, and remember: the best way to eat an elephant is one bite at a time.

CYBER.ORG: Networking Fundamentals – 1.3.1 – Copper Cables & 1.3.1 Activity – Ethernet Cat5e Patch Cable Assembly

Objective

  • The student will be able to summarize the types of cables and connectors and explain which is the appropriate type for a solution.

Resources:

  • See PowerPoint presentation: 1.3.1 – Copper Cables.pptx

Links:

Topics Discussed:

  • Networking Basics
  • Networking Fundamentals
  • Ethernet
  • EIA/TIA
  • 568A & 568B Standards
  • Cat5, 5e & 6
  • Local Area Network
  • Cable Management

Assignment:

  1. Begin reading the 1.3.1 – Copper Cables.pptx presentation on the Google Classroom. This lesson will introduce you to different types of copper cables and their standard characteristics.
  2. Next, visit the How to Make a Network Cable: link at https://www.wikihow.com/Make-a-Network-Cable for instructions on how to build a Cat5e cable to the EIA/TIA 568A or 568B spec. Read through the instructions completely before proceeding. Pay particular notice to the difference between a “passthrough” cable and a “crossover” cable.
  3. Visit the rolling cart to pick up your tools and materials. You will need a arm’s length of Cat5e cable, two RJ-45 cable ends, and a crimper tool.
  4. Follow the instructions to build your passthrough patch cable.
  5. Once you have your passthrough cable built, test it using the provided cable tester. If your cable test is successful, you may proceed to build a “crossover” cable for extra credit.
  6. Use clear tape and a marker to label your cables with your name and what type of cable it is (passthrough or crossover), and place it in the wire basket on the front table in the room.
  7. Once they are graded, you are free to take your Cat5e cable home for your own use. Cables left behind will be deployed within the department.
