  1. Wireless introduction

  2. What is Wireless LAN A wireless LAN links network users to LAN serviceswithout theuse of a cabled connection to attach them to the networkinfrastructure. In most companies it acts as an extension of a wired network, but in smaller businesses or hard-to-wire areas it may be the only LAN connection for the user. Wireless Client Access Point

  3. Wireless LAN Advantage • High removal • Without rewire • Fast, Reliable Performance for Mobil users

  4. 802.11 Standard

  5. 802.11 Operation modes 1. Infrastructure mode 2. Ad-Hoc mode 3. Point-to-point mode 4. Point to Multi Point Network

  6. Infrastructure mode • An 802.11 networking framework in which devices communicate with each other by first going through an Access Point (AP). In infrastructure mode, wireless devices can communicate with each other or can communicate with a wired network.

  7. WAN Port Infrastructure Mode Internet Cable or xDSL Modem LAN Port Parallel Port Wireless Router IEEE 802.3 Wireless LAN IEEE 802.11 Switch

  8. Ad-Hoc mode • An 802.11 networking framework in which devices or stations communicate directly with each other, without the use of an access point (AP).

  9. Ad-Hoc mode Peer to Peer Wireless LAN

  10. Point-to-point mode • Point-to-point mode will allow you to connect two LANs together, the wireless bridge will only work with another wireless bridge .

  11. Point-to-point mode Wireless bridge Wireless bridge

  12. Point to Multi Point Network • Point to Multi Point Network will allow you to connect multiple wireless LANs together.
