I
Institute of Electrical and Electronics Engineers. A professional society serving electrical engineers
IEEE
through its publications, conferences, and standards development activities. The body responsible for
the Ethernet 802.3 and wireless LAN 802.11 specifications.
The wired Ethernet network.
infrastructure
A device (such as an access point, bridge, or base station) that connects client adapters to a wired LAN.
infrastructure
device
The Internet Protocol address of a station.
IP address
The number used to identify the IP subnetwork, indicating whether the IP address can be recognized
IP subnet mask
on the LAN or if it must be reached through a gateway.
Internetwork Packet Exchange. The NetWare network layer protocol used for transferring data from
IPX
servers to workstations.
L
LEAP, or EAP-Cisco Wireless, is an 802.1X authentication type. With LEAP, a username and password
LEAP
are used by the client adapter to perform mutual authentication with the RADIUS server through an
access point.
M
The Media Access Control (MAC) address is a unique serial number assigned to a networking device
MAC address
by the manufacturer.
Message integrity check. MIC prevents bit-flip attacks on encrypted packets. During a bit-flip attack,
MIC
an intruder intercepts an encrypted message, alters it slightly, and retransmits it, and the receiver
accepts the retransmitted message as legitimate. The client adapter's driver must support MIC
functionality, and MIC must be enabled on the access point.
Any of several techniques for combining user information with a transmitter's carrier signal.
modulation
Packets transmitted to multiple stations.
multicast packets
The echoes created as a radio signal bounces off of physical objects.
multipath
O
Orthogonal frequency division multiplexing. A multicarrier modulation method for broadband wireless
OFDM
communications.
Packets that were discarded because the access point had a temporary overload of packets to handle.
overrun packets
