I
IEEE
Institute of Electrical and Electronic Engineers. A professional society serving
electrical engineers through its publications, conferences, and standards
development activities. The body responsible for the Ethernet 802.3 and
wireless LAN 802.11 specifications.
infrastructure
The wired Ethernet network.
IP address
The Internet Protocol (IP) address of a station.
IP subnet mask
The number used to identify the IP subnetwork, indicating whether the IP
address can be recognized on the LAN or if it must be reached through a
gateway. This number is expressed in a form similar to an IP address; for
example: 255.255.255.0.
isotropic
An antenna that radiates its signal in a spherical pattern.
M
MAC address
Media Access Control address. A unique 48-bit number used in Ethernet data
packets to identify an Ethernet device, such as an access point or your client
adapter.
MAP
Mesh Access Point
MBSSID
Multiple basic SSID. Each multiple basic SSID is assigned a unique MAC
address. You use multiple BSSIDs to assign a unique DTIM setting for each
SSID and to broadcast SSIDs in beacons (one SSID per beacon).
MIMO
Multiple Input/Multiple Output
modulation
Any of several techniques for combining user information with a transmitter for
a carrier signal.
multipath
The echoes created as a radio signal bounces off of physical objects.
multicast packet
A single data message (packet) sent to multiple addresses.
O
omni-directional
This typically refers to a primarily circular antenna radiation pattern.
OFDM
Orthogonal frequency division multiplex is a modulation technique used by
IEEE 802.11a-compliant wireless LANs for transmission at 6, 9, 12, 18, 24, 36,
48, and 54 Mb/s.
