Appendix B - Glossary

ACU

 - Atheros Client Utility (ACU) is the utility that allows for configuration of the

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.
