CEC Huada Electronic Design Co., Ltd 33 5.3Technical terms explanation ∷ WLAN:the abbreviation of Wireless Local Area Network. ∷ AP（Access Point）:wireless Access Point. ∷ SSID：also be abbreviated with ESSID，it’s denotation character of AP. ∷ Point to point Mode（Ad-hoc）：point to point network mode in IEEE 802.11g standard，it can be formed without AP.A few network interface cards can compose a network group,of course they must have the same SSID and channel to insure they can connect. Figure 5-1 point-to-ponit mode（Ad hoc） ∷ Infrastructure Mode：The mode needs AP fulfils IEEE802.11b/g Standard.All communications are connected by AP,just as the routers in wired network.wireless network in this mode can connect to the wired network through the LAN interfacein AP.
CEC Huada Electronic Design Co., Ltd 34 Figure5-2 Infrastructure ∷ 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
CEC Huada Electronic Design Co., Ltd 35 encryption, IEEE802.11X/EAP authentication and PSK techniques,but also support AES(a new security mode)。 ∷ PSK(Per-shared Key)： Wi-Fi Protected Access（WPA）personal mechanism. ∷ TKIP(Temporal Key Integrity Protocol)：a wireless security encryption mechanism of Wi-Fi Protected Access. ∷ AES(Advanced Encryption Standard)：higher encryption mechanism，it uses Symmetrical Block Encryption technique,it’s the preferred standard to use in commerce and government.The standard is used to achieve WPA2. ∷ CCK：the modulation technique of IEEE802.11b used. ∷ OFDM：the modulation technique of IEEE802.11g used. ∷ TLS(Transport Layer Security)：it supports the common authentication of basis and credence between clients and network,it performs the authentication according to the credence of client and server,and it’s used to dynamicly produce WEP secret key according to user’s work,and then protects the security of the latter communication between client and access point. ∷ WAPI：it’s short for WLAN Authentication and Privacy Infrastructure in English，it’s a kind of wireless transfers protocol,it is WLAN security resolvd scenario,which is mian against the question of WEP protocol security in IEEE 802.11 standard and advanced in Chinese WLAN National Standard GB15629.11.
