With the popularity of the application of IEEE802.11 series, the security problems for the mobile users of Wireless LAN Access is increasing more and more, day by day. Owing to the characteristics of wireless network, transmitting data through the medium of air, it is not easier to guard against the act of unauthorized accessing and illegal wiretapping. This characteristic of transmission without a real line makes the use of VLAN more meaningful in the wireless network. The VLAN technology, with the standard of IEEE Std 802.1Q, could further dispatch the different groups of personnel to the different virtualized intranets. Thus, it could solve the security problems for the mobile users when using the wireless network offered by the public or the private enterprises.
