∷ IEEE 802.11b：IEEE 802.11b Standard defined the Physical Layer used as data transfers in
WLAN and Medium Access Control Sublayer,it adopted 2.4GHz wireless frequency in Physical
Layer and the most speed may reach 11Mbps.
∷ IEEE 802.11g：IEEE 802.11g Standard is the successor of IEEE 802.11b Standard,the data
transfers speed can achieve 54 Mbps.IEEE 802.11g Standard can also resolve the disturbance
problem between Bluetooth products and IEEE802.11b products.
∷ Site Survey：It can scan in the area where the users are,and support a usable AP list for users to
decide the wireless AP they want conveniently.
∷ Wired Equivalent Privacy：called WEP for short,it’s a part of wireless protocol，its purpose is
supporting confidentiality and data integrality,and protect the access to the Infrastructure
Network through rejecting all not WEP information package.
∷ Wi-Fi(Wireless-Fideliy)：Wireless transport criterion.
∷ WPA(Wi-Fi Protected Access)：Wi-Fi Protected Access criterion,the criterion enhances data
security and the ability of access control in WI-Fi WLAN,protects all editions of IEEE 802.11,and
the security is better than WEP technique.WPA is derived from IEEE 802.11i Security Standard
and compatible with it.Since it’s installed,it will support high quality of data security for WLAN
users and ensure that only the accredited persons can join the network.
∷ WPA2：It achieve all the charaters of IEEE802.11i standard.WPA2 do not only adopt TKIP
