EAP—Extensible Authentication Protocol, which provides a generalized framework
for several different authentication methods.
ESS—Extended Service Set. More than one BSS is configured to become an ESS.
LAN mobile users can roam between different BSSs in an ESS (ESS-ID, SSID).
Ethernet—A popular local area data communications network, which accepts
transmission from computers and terminals.
Infrastructure—An integrated wireless and wired LAN is called an
infrastructure configuration.
RADIUS—Remote Access Dial-In User Server is an authentication method used in
conjunction with EAP for 802.1x authentication and session based keys.
Roaming—A wireless LAN mobile user moves around an ESS and maintains a
continuous connection to the infrastructure network.
RTS Threshold—Transmitters contending for the medium may not be aware of each
other (they are "hidden nodes"). The RTS/CTS mechanism can solve this problem. If
the packet size is smaller than the preset RTS Threshold size, the RTS/CTS mechanism
will not be enabled.
VLAN—Virtual Local Area Network. A LAN consisting of groups of hosts that are on
physically different segments but that communicate as though they were on the same
segment.
WEP—Wired Equivalent Privacy is based on the use of security keys and the popular
RC4 encryption algorithm. Wireless devices without a valid WEP key will be excluded
from network traffic.
WPA—Wi-Fi Protected Access.
