Yagi Antenna
Flickenger design Antenna

Assignment:

Today, we will continue the build phase of our directional antenna project. Remember that the goal is to sustain a 2.4 GHz Wi-Fi signal over a minimum distance of 100 yards (300 ft or ~92m).

All tools and equipment are on the metal cart in the front of Room 225. The transmitter testing cart is in the front of Room 225, and the username and password is on a piece of tape on the side of the cart. Use the velcro strap to secure your can to the tripod and use the tripod handles to angle your can to point at the upright antennas on the target router located on the receiver cart. The receiver cart (with the target router) is in the back of the room, and the username and password is located on a stickynote on the PC case.

Please use this time to make progress on your project. On Friday, November 21st, I will set up the testing carts on both ends of the hallway outside my room in the 200 building so we can test all completed antennas to allow those with working products to see the results and modify their designs if necessary. You should have a finished antenna prepared to test at that time so you can tweak the design if necessary before the final test on the week of the 25th!

We will conduct final tests on Tuesday, November 25th. 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).

Reminder: The team (or individual) that produces the antenna that can reliably sustain the highest quality signal (as measured by Signal Quality percentage and Signal as measured in decibels) over the longest distance will receive a personal pizza and wings party, to be held on Wednesday, November 26th while everyone else writes a four paragraph personal reflection describing their participation in this project.

Good luck, and remember: Your antenna doesn’t have to be perfect, it just has to be better than everyone else’s.

Topics Discussed:

  • Wireless Networking
  • 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 Thanksgiving 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 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).
  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). Submit a completed Project Team Work Plan to the instructor as soon as it is completed.
  4. 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.
  5. You may work in Room 225, but you will need to notify the instructor if you need access the tools in Room 212.
  6. All tools and equipment are 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 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!
  8. We will conduct initial tests the week of November 18th. 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 during the week of November 25th.
  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 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.

Key Terms:

  • Physical Address The unique, burned-into read-only memory address of a network interface. This is also called the media access control address, or MAC address. MAC addresses are burned into the read-only memory of every single network interface, such as wireless network adapters and network interface cards. This makes it virtually impossible to change the device’s MAC address.
  • Logical Address An address assigned by software and, as such, can be changed. It includes two parts, the network address and the host address. The most common types of logical addresses are those assigned by the IP protocol and are called IP addresses.
  • Default Address Class A class designation (A through E) that specifies a default subnet mask value which defines the default network address portion of the IP address.
  • Internet Protocol (IP) The principal communications protocol in the internet protocol suite that is used to route information over the Internet.
  • Transmission Control Protocol (TCP) An important protocol in the internet protocol suite that enables two hosts to establish a connection and exchange data.
  • User Datagram Protocol (UDP) An important protocol in the internet protocol suite that is generally used when speed in transmission is more important than accuracy since the sending computer doesn’t verify that the packets were correctly received.
  • Domain Name System (DNS) A protocol that helps internet users and network devices discover other devices using a human-readable hostname instead of numeric IP addresses.
  • Hypertext Transfer Protocol (HTTP) A protocol that governs the transfer of web content between computers.
  • Hypertext Transfer Protocol Secure (HTTPS) A protocol that combines HTTP with the Secure Sockets Layer (SSL) protocol to securely transfer web content between computers.
  • Simple Mail Transfer Protocol (SMTP) A protocol used to send email.
  • Post Office Protocol 3 (POP3) A protocol used to receive email. With POP3, email is deleted from a server after it is downloaded to a client.
  • Internet Message Access Protocol (IMAP) A protocol used to receive email. With IMAP, email is saved on a server even after it is downloaded to a client.
  • IEEE 802 Standards A family of standards that deal mostly with how data is transferred between hosts in a local area network (LAN).
  • IEEE 802.11 Standards A family of standards under the 802 standards that deal with how data is transferred between hosts in a wireless network. Popular 802.11 standards are 802.11a, 802.11b, 802.11g, 802.11n, and 802.11ac.
  • IEEE 802.11 Encryption Protocols Security protocols that govern how data in a wireless network is secured by encryption. Examples of these protocols are Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), and WPA2.
  • Frequency A characteristic of a radio signal that carries digital information in a wireless network. 802.11 standards specify two frequencies, 2.4 GHz and 5 GHz.
  • Attenuation A feature of radio waves where the signal becomes weaker as the wave travels further from its point of origin. 802.11 standards require that signals are strong enough to cover a specific distance.
  • Speed A characteristic of 802.11 protocols that require protocols to transfer data at a specific number of bits per second.
  • Network Architect A person that develops and implements an organization’s communication network, including the hardware and software components needed for both physical and wireless connections.
  • Network Administrator A person that maintains and expands a company’s network. They install and configure network media, create and manage user accounts, implement firewalls and other network security, manage an organization’s mail system, configure network printers, and maintain Internet connectivity.
  • Network Technician A person that works closely with network administrators to ensure uninterrupted access to the company network. They troubleshoot problems reported to a company’s IT help desk and assist users in resolving network connection problems, such as replacing defective network cables and modifying Wi-Fi settings.

Topics Discussed:

  • Why is it important that computers on a network use the same protocols?
  • How do computer networks locate specific devices on the network?
  • What career opportunities are available in computer networking?
