WLAN (Wireless Local Area Network, WLAN (wireless local area network)) technology is one of focus of the current communications field, follows relevant regulations in 802.11 protocol suites, provides the wireless access service to the user in 2.4GHz or 5GHz frequency range.Usually the user need lay one or more access point apparatus and set up the wlan network that covers whole building or area.Wlan system is not a wireless system completely, and its server and backbone network still are placed in fixed network, and just the user can pass through the wireless mode access network.
A common wlan network comprises wireless client (Station), AP (Access Point, access point) and AC (Access Controller, access controller).
Wherein, wireless client is terminals such as the PC (Person Computer, personal computer) that has wireless network card or portable notebook computer;
AP is used to provide the bridging functionality of wireless client to local area network (LAN), carries out wireless wired and wired wireless frame conversion of arriving of arriving between wireless client and local area network (LAN);
Wherein, AP is divided into two kinds of Fat AP (promptly usually so-called fat AP) and Fit AP (promptly common so-called thin AP), and Fat AP can finish the cut-in operation of wireless clients such as user's wireless access, user right authentication, user safety strategy enforcement.Fit AP then need just can provide a complete set of wireless client cut-in operation in the cooperation of AC, and wherein AC is responsible for the OAMAgent, security control of configuration monitoring, roaming management, the AP of access control, forwarding and statistics, the AP of wireless network etc.; The functions such as statistics that the encryption and decryption of responsible 802.11 messages of Fit AP, 802.11 PHY (physical layer) function, the management of accepting AC, RF (radio frequency) eat dishes without rice or wine.
