802.11
See IEEE802.11
BSS
Basic Service Set, is an IEEE802.11 definition of a managed wireless network that comprises a single access point and its wireless devices. Compare with BSS and IBSS. See WirelessCapabilities.
ESS
Extended Service Set is defined by the IEEE802.11 as "A set of one or more interconnected basic service sets (BSSs) and integrated local area networks (LANs) that appears as a single BSS to the logical link control layer at any station associated with one of those BSSs." Compare with BSS and IBSS. See WirelessCapabilities.
DFS
Dynamic Frequency Selection, defined in the IEEE802.11h standard. Procedure to recognize other radio-based applications such as military radar and evade such frequencies to avoid interferences.
HAL
Hardware Access Layer, see HAL? and HAL usage
IBSS
Independant Basic Service Set, is an IEEE802.11 definition of a standalone network comprised of one or more ad-hoc wireless devices connected together. Compare with BSS and ESS. See WirelessCapabilities.
MadWifi
Multiband Atheros Driver for Wireless Fidelity. The driver codebase name after June 2006 (see below for more). MadWifi is a linux kernel driver that supports wireless chipsets from Atheros.
MadWifi-NG
Multiband Atheros Driver for Wireless Fidelity-NG. The codebase in the interval November 2005-June 2006 is called MadWifi-NG, and after June 2006, the codebase is called simply MadWifi.
MadWifi-Old
Multiband Atheros Driver for Wireless Fidelity-Old. Old refers to the Madwifi driver released prior to November 2005. This driver was deprecated in June 2006. The codebase in the interval November 2005-June 2006 is called MadWifi-NG, and after June 2006, the codebase is called simply MadWifi.
PCI
Peripheral Component Interconnect, a bus technology for a computer.
RSSI
Received Signal Strength Indicator, see UserDocs/RSSI
STA Mode
TPC
Transmit Power Control, defined in IEEE802.11h standard. Procedure to automatically limit the transmit power to the minimum level needed to keep contact to the communication partner.
VAP
Virtual Access Point, a technique to allow one physical access point to behave like it is multiple access points. In some contexts, it also refers to having multiple modes of operation (e.g. station, monitor, wds) running at the same time.
VPN
Virtual Private Network, allows connecting private over public networks, usually secured by encryption.
WDS
Wireless Distribution System, see AboutWDS.
WEP
Wired Equivalent Privacy, encryption standard used by Wireless Networks following the various IEEE802.11 specifications. Unsecure, should be regarded as being deprecated, superceded by WPA.
WMM
Wifi MultiMedia, a subset of 802.11e
WPA
Wifi Protected Access
