In this network is the computer era, along with the cable network widely, by an efficient, flexible networking, wireless networking technology for the advantage of also developing fast. Wireless LAN is a computer network and wireless communication technology combined with the product. From a professional point of view, wireless local area network using a wireless multiple access channel is an effective method to support the communication between computers, and mobile communications, personalization and multimedia applications possible. In laymans terms, wireless local area network (Wireless local-area network, WLAN) that is not the same time using the traditional cable, Ethernet or token network functions. Computer network transmission media often rely copper or fiber optic cable, LAN cable form. But the cable network wiring in some cases be subject to restrictions: wiring, rebuilding project large; line easily damaged; Network nodes can not be moved. Especially when compared from the remote node should be connected, the laying of dedicated communication line wiring construction difficult, costly, time-consuming, and demand is rapidly expanding network congestion has become a serious bottleneck. Wireless LAN is the solution over wired networks to problems. 1.the history of the wireless LAN Speaking of the historical origins of the wireless network may be even earlier than you imagined. Preliminary application of wireless networks can be traced back 50 years ago during World War II, when the U.S. Army using radio signals as data transmission. They developed a set of radio transmission
