  1. Wireless NetworkingTutorial Janie Mohajerin and Alton Wilson Start

  2. Instructions • To move to the next part of the tutorial press: • There will be quizzes after each section. START

  3. Section 1: Network Protocols of Wireless Networking • A network protocol defines rules and conventions for communication between network devices. • Network protocols include mechanisms for devices to identify and make connections with each other, as well as formatting rules that specify how data is packaged into messages sent and received. • Hundreds of different computer network protocols have been developed each designed for specific purposes and environments.

  4. Types of Network Protocols HTTP • HTTP (Hypertext Transfer Protocol) • Provides a standard for web browsers and servers to communicate • Communicate using HTTP responses and messages

  5. Types of Network ProtocolTCP / IP • TCP (Transmission Control Protocol) – corresponds to the transport layer • IP (Internet Protocol)- corresponds to the network layer • The terms are often used interchangeably • The average person on the Internet works in a predominately TCP/IP environment. Web browsers, for example, use TCP/IP to communicate with Web servers.

  6. Quiz Time Section 1 Answer the following questions to see what you have learned about protocols. Click the to choose your answer. Begin Quiz

  7. Question 1 How many different network protocols are there? • Two : IP and TCP • One: HTTP • There are hundreds

  8. CORRECT!!!! • C. There are hundreds because protocols have been designed to serve different environments and purposes • Move on to question 2

  9. NOPE… try again!!! • Go Back to Quiz

  10. Question 2 • Which protocol provides a standard for web browsers and servers to communicate? • HTTP • IP • TCP

  11. CORRECT!!! • HTTP provides a standard for all web browsers. • Move to Question 3

  12. So SORRY… So Wrong!! • Back to Quiz

  13. Question 3 • The average person on the Internet uses this protocol to communicate with Web browsers. A. HTTP B. IP or TCP C. Network

  14. CORRECT!! • The average person on the Internet works in a predominately TCP/IP environment. Web browsers, for example, use TCP/IP to communicate with Web servers. • Move on to Section 2

  15. No… sorry. Try again. • Back to quiz

  16. Section 2: Standards of Wireless Networking • 802.11 is the generic name of a family of standards for wireless networking related to Wi-Fi. • The numbering system for 802.11 comes from the IEEE, who uses "802" to designate many computer networking standards including Ethernet.

  17. IEEE • In 1997, the Institute of Electrical and Electronics Engineers (IEEE) created the first WLAN (Wireless Local Area Network) standard. • They called it 802.11 after the name of the group formed to oversee its development.

  18. Types of Standards:Wi-Fi Technologies • 802.11a • 802.11b • 802.11g • 802.11n (the newest standard)

  19. Pros and Cons of 802.11n • Pros of 802.11n • fastest maximum speed and best signal range • more resistant to signal interference from outside sources • Cons of 802.11n • standard is not yet finalized; costs more than 802.11g • the use of multiple signals may greatly interfere with nearby 802.11b/g based networks.

  21. Quiz Time Section 2 Answer the following questions to see what you have learned about protocols. Click the to choose your answer. Begin Quiz

  22. Question 1 What is the name for the family of wireless networking standards? • IEEE • WLAN • 802.11

  23. No Sorry… that’s just wrong. Back to Quiz

  24. Correct!!! • 802.11 is the generic name of a family of standards for wireless networking related to Wi-Fi. Continue to Question 2

  25. Question 2 • What is IEEE? • A unique standard • Creator of standards • Creator of WLAN

  26. Correct!!! • In 1997, the Institute of Electrical and Electronics Engineers (IEEE) created the first WLAN (Wireless Local Area Network) standard. Continue to Question 3

  27. Naaaahhh… try again. Back to Quiz

  28. Question 3 According to the video, what is the best standard available today? • 802.11n • 802.11g • 802.11b

  29. Correct!!! • fastest maximum speed and best signal range • more resistant to signal interference from outside sources Continue to Section 3

  30. Nope.. Try again Back to Quiz

  31. Section 3: Wireless Networking Equipment • Network Routers • Access Points • Adapters • Print Servers • Range Extender

  32. Network Routers These routers support all home computers configured with wireless network adapters. They also contain a network switch to allow some computers to be connected with Ethernet cables. Wireless routers allow cable modem and DSL Internet connections to be shared. Many wireless router products include a built-in firewall that protects the home network from intruders.

  33. Access Points Used with routers to join the wireless client to the Ethernet network. Commonly used in large office buildings. Can be used in the home to extend the home network.

  34. Adapters Allows a computing device to join a wireless LAN (Local Area Network). Wireless network adapters contain a built-in radio transmitter and receiver. Each adapter supports one or more of the 802.11a, 802.11b, or 802.11g Wi-Fi standards. Most notebook computers are now manufactured with built-in wireless networking. Small chips inside the computer provide the equivalent functions of a network adapter. These computers obviously do not require separate installation of a separate wireless network adapter.

  35. Print Servers Allows one or two printers to be conveniently shared across a WiFi network. Wireless print servers offer the following advantages: Allows printers to be conveniently located anywhere within wireless network range, not tied to the location of computers Does not require a computer be always turned on in order to print Does not require a computer to manage all print jobs, that can bog down its performance Allows administrators to change computer names and other settings without having to re-configure the network printing settings.

  36. Range Extender A wireless range extender connects via Wi-Fi to a router or access point. Increases the distance over which a WLAN signal can spread, overcoming obstacles and enhancing overall network signal quality.

  37. Quiz Time: Section 3 Answer the following questions to see what you have learned about protocols. Click the to choose your answer. Begin Quiz

  38. Question 1 Name the Hardware in the picture A. Range Extender B. Print Server C. Access Point

  39. No… Try again • Back to Quiz

  40. CORRECT!!! • Print Server • Continue to Question 2

  41. Question 2Name the Hardware in the picture A. Adapter B. WLAN C. Router

  42. NO.. Sorry.. Way off. • Back to Quiz

  43. CORRECT!!! • Wireless Adapter • Continue to Question 3

  44. Question 3Name the Hardware in the picture A. Access Point B. Wireless Network C. Wireless Router

  45. No… do over… • Back to Quiz

  46. CORRECT!!! • Wireless Router • Access points are found within the, router but they are not the router. 
