WLAN Technology And Design

Since 1990s, computer has been used every where in our life. Userswant more computers to be connected in a net within a more complicatedform. However, because of being subjected to design or the environmentconditional check and supervision, widespread exist a series of problems inthe physical, logic and the funds aspects, the wired network can't fulfillpeople's requirements, especially when involving a network to move andre-set up. Therefore, Wireless LAN has been created.With the development of Wireless LAN, it has been applied in manyareas of our life. As a new technology, Wireless LAN has many advantagesand a huge market. Considering the request of economic growth of the 21century, it is very urgent to research how to make use of Wireless LANeffectively, and build it in a more convenient way.This article introduces the fundamental rules of Wireless LAN,including network protocol, management, and safety. It also has a roadmapof present Wireless LAN application and a predict of the future. Then it isabout the principle of Wireless LAN's design, the requirement of theconstruction and the main point of a project. In the end, the author gives areal case of implement of Wireless LAN with the theory.
