Application of the Wireless LAN in Campus Based on 802.11

The wireless local area network is quite convenient data transmission system,which to interconnect the computer equipments using wireless communication technology,and to form network system for intercommunication and realizing the resources sharing.It uses Radio Frequency technology,instead of old local area network with twisted-pair copper wire,and makes the wireless local area network use simple architecture which allows users to access.IEEE 802.11 is the first standard of wireless local area network,which mainly uses to solve questions of office LAN and campus network,users and the user terminals wireless access.Firstly, it introduces the concept of the wireless local area network and composition.Secondly,it analyses wireless LAN series standard,implementation principle and security mechanism based on 802.11,and presents three methods of constructing network in the campus WLAN.Finally,it points out the future direction of development.
