WLAN Wireless Local Area Network
802.11 A family of specifications developed by the IEEE for WLAN
technology.
802.11a An extension to 802.11 WLAN standard that provides up to 54 Mbps
transmission in the 5 GHz UNI radio band.
802.11b An extension to 802.11 WLAN standard that provides up to 11 Mbps
transmission in the 2.4 GHz ISM radio band. 802.11b uses DSSS
modulation.
802.11g An extension to 802.11 WLAN standard that provides up to 54 Mbps
transmission in the 2.4 GHz ISM radio band. 802.11b uses OFDM
modulation and is backwards compatible with 802.11b.
802.11n A proposed amendment which improves upon the previous 802.11
standards by adding multiple-input multiple-output (MIMO) and many
other newer features.
Ad-Hoc A group of computers each with wireless adapters, connected as an
independent WLAN.
AES Advanced Encryption Standard
BSSID Basic Service Set ID
DHCP Dynamic Host Configuration Protocol
DSSS Direct Sequence Spread Spectrum. DSSS is one of two types of
spread spectrum radio. The other is frequency-hopping spread
spectrum (FHSS).
QoS Quality of Service
OFDM Orthogonal Frequency Division Multiplexing
PSK Pre-shared Key(s), in connection with WPA, WPA2
RADIUS Remote Authentication Dial In User Service
RTS Request to Send
SSID Service Set Identifier. A 32-character unique identifier attached to the
header of packets sent over a WLAN that acts as a password when a
mobile device tries to connect to the BSS.
TCP/IP Transmission Control Protocol/Internet Protocol
TKIP Temporal Key Integrity Protocol
WDS Wireless Distribution System
WEP Wired Equivalent Privacy. A security protocol for
WLANs defined in the IEEE 802.11 standard.
WPA Wi-Fi Protected Access
WPA2 Wi-Fi Protected Access 2. The next generation of
Wi-Fi security, based on the 802.11i standard.
