Appendix B - Glossary
ACU
- Atheros Client Utility (ACU) is the utility that allows for configuration of the
AMBIT WLAN 802.11 a/b/g device
Access Point - An internetworking device that seamlessly connects wired and wireless
networks together.
Ad Hoc - A peer- to-peer wireless network without Access Point. A group of wireless clients
consistent an independent wireless LAN.
Backbone - The core infrastructure of a network, the portion of the network that transports
information from one central location to another central location. The information is then
off-loaded onto a local system.
BSS
- Basic Service Set. An Access Point associated with several wireless stations.
ESS - Extended Service Set. More than one BSS can be configured as an Extended Service
Set. An ESS is basically a roaming domain.
ESSID –Extended Service Set Identifier. The length of the ESSID information is between 0
and 32 octets. A 0 length identifier indicates the broadcast SSID.
Ethernet - A popular local area data communications network, originally developed by
Xerox Corp., which accepts transmission from computers and terminals. Ethernet operates on
10/100 Mbps transmission rate over shielded coaxial cable or over shielded twisted pair
telephone wire.
Infrastructure - An integrated wireless and wired LAN is called an infrastructure
configuration.
Roaming - A function that allows one to travel with a mobile end system (wireless LAN
mobile station, for example) through the territory of a domain (an ESS, for example) while
continuously connecting to the infrastructure.
SSID – Service Set Identifier (SSID) is the network name used by the Wireless LAN . The
length of the SSID information is between 0 and 32 octets.
WEP
–Wired Equivalent Privacy. The optional cryptographic confidentiality algorithm
specified by IEEE 802.11 used to provide data confidentiality that is subjectively equivalent
to the confidentiality of a wired local area network (LAN) medium that does not employ
cryptographic techniques to enhance privacy.
