It can meet various types of portable machine39。s network requirements, the puter can realize the remote LAN access, fax, and other functions. Wireless LAN technology as a means of network access can be quickly applied to networking and need to move in the Internetwork roaming occasions, and in places difficult to set up cable network to provide strong support. Therefore, WLAN has been applied in all walks of life, has been widely popular, has bee the wireless munications and Internet technology bined with the power to one of the new development. The greatest advantage of WLAN is to realize the interconnection network mobility, it can significantly improve user access to information, timeliness and effectiveness, but also to overe the inconvenience of cable restrictions. However, as wireless local area network applications of great openness, the scope of the data transmission is difficult to control, so the wireless LAN will face a very serious security problems. Wireless LAN security issues since the birth of their development has been troubled by an important this paper, wireless local area network at this stage the main security problem faced, and describes the corresponding popularization of wireless broadband technology to bring convenienc
