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 Protocol TCP / 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

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

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.

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.

56. Cell Phone Data Networks Better known as “Cellular Networks” The network is distributed over areas called “Cells” Each cell has a transceiver called a “Base Station”

57. Cellular Networks In a cellular radio network the coverage area is divided into regular shaped cells. Each cell has multiple frequencies. Cells were established because multiple frequencies could be used over shorter ranges. Cell Diagram

58. Cell to Cell The cellular network system allows wireless communication over large areas Calls/Data is switched or handed off from one cell to another

59. Cellular Networks Sprint and Verizon networks use Code Division Multiple Access (CDMA). AT&T and T-Mobile use Global System for Mobile communication (GSM) technology. Tri-band, quad-band, or "world phones" operate on Global System for Mobile communication (GSM) networks in the U.S. and abroad.
