【正文】 g, wireless working technology for the advantage of also developing fast. Wireless LAN is a puter work and wireless munication technology of the bination. From a professional perspective, use of wireless wireless LAN multiple access channel is an effective way to support munication between puters, and mobile munications, personalization and multimedia applications possible. Wireless LAN (Wireless localarea work, WLAN) is a wireless munications technology and work technology product of the bination. From a professional point of view, the wireless LAN work through the wireless channel to municate between devices and to achieve mobile munications, personalization and broadband. More simply, the use of wireless LAN cable is not the case, to provide Ether connectivity. Wireless LAN with the rapid development of wireless munication technology and the emergence of a new work. This article describes the basic ponents of wireless local area work, topology, advantages and disadvantages, detailing several wireless LAN standards, and lists the wireless LAN security issues and detailed solutions. Potential applications, a wide range of market needs and technology can be realized, and promote the improvement of wireless LAN technology and industrialization, has been mercially available works are also confirmed this. With the work, mercial and other wireless LAN technology continues to evolve, wireless local area work will usher in golden age of development.
