Transcript

  • 1. WiFi for Mobile Networks Teresa Ulmer EdTech 541
  • 2. What is WiFi?  “Wireless Fidelity”  Wireless communication between a computer and an Access Point (AP) and the Internet
  • 3. What is WiFi? Antenna transmits radio waves Access point sends info to the Internet Wireless Adaptor converts data into radio waves Access Point (connected to LAN) translates radio waves into data Internet responds to data Internet data travels to Access Points AP sends data in form of radio waves to wireless devices
  • 4. What is WiFi?  One access point connects several devices to the Internet  If AP fail or if too many people try to use high-bandwidth applications simultaneously  Interference can occur  Connections can be lost
  • 5. Why have WiFi in High School Classrooms?  Data Sharing  Access to Internet for Research  Access to Tools that Enhance Learning  Graphing calculators  Simulations  Virtual labs  E-books  Student response systems  Improves Classroom Communication ALLOWS FOR:
  • 6. Steps for integrating a WiFi Network in a High School 1. Identify users Who will the network serve?  Students  Teachers  Administrators  Counselors  Support staff  Guests
  • 7. Steps for integrating a WiFi Network in a High School 2. Define coverage area Where are the people who will be served by the network?  classrooms  media center  cafeteria  common areas  offices  outside of buildings  gymnasium  sports fields
  • 8. Steps for integrating a WiFi Network in a High School 3. Determine uses for the network What are the users going to do on the wireless network?  Gather/organize student data  Grade students  Communication  Research  Planning/prepping for courses  Using educational tools
  • 9. Steps for integrating a WiFi Network in a High School 4. Plan for growth  How many users will be accessing the network (today and in the future)?  Students  Staff  Guests
  • 10. Steps for integrating a WiFi Network in a High School 5. Determine network layout a. How many access points (AP) will be needed  Each AP supports a set number of devices b. Where the AP should be located  Each AP needs an Ethernet cable and power
  • 11. Steps for integrating a WiFi Network in a High School 6. Install Access Points and Connect them to the Network Modem (Cable/DSL)Internet Router Wireless Access Point (WAP) Clients
  • 12. Steps for integrating a WiFi Network in a High School 7. Configure network  Set SSID (service set identifier)for the Network  Unique name of wireless local area network (WLAN)  Case-sensitive sequence of alphanumeric characters (up to 32)  Enable encryption (WPA-PSK2 etc.) and “password” to allow only authorized devices to access the network  Set WAPs with same SSID and encryption set  Push configurations from a central controller or configure each individual AP
  • 13. Steps for integrating a WiFi Network in a High School 8. Test the network and trouble shoot  Dead zones  Interference (file cabinets; lockers; microwaves; building materials  Performance issues (low speeds, etc. requires software tools)  Move WAPs to achieve optimal coverage/performance
  • 14. Steps for integrating a WiFi Network in a High School 9. Provide access to the network  Students  Teachers  Administrators  Counselors  Support staff  Guests
  • 15. Potential Problems  Should overlap  # of APs required to provide wireless coverage in desired locations  Coverage
  • 16. Potential Problems  Depends on usage (can be projected using packet analyzer software)  # of APs required to provide the minimum acceptable data rates  min data rate = size of cell = Access Points  Capacity
  • 17. Potential Problems  Security  Encrypt data being transmitted  Authenticate users  Eliminate of rogue access points
  • 18. Potential Problems  Security  Needs depend on the type of WLAN you're accessing and the level of data encryption required  Three options for secure WLAN encryption and authentication: 1. Wi-Fi Protected Access (WPA) 2. Wi-Fi Protected Access 2 (WPA2) 3. Virtual Private Networking (VPN)  effective security for mobile users accessing the network
  • 19. WPA and WPA2
  • 20. Virtual Private Networking (VPN)
  • 21. Potential Problems  Misuse
