OL-7293-01
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
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.
modulation
Any of several techniques for combining user information with a transmitter’s
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 Mbps.
P
packet
A basic message unit for communication across a network. A packet usually includes routing
information, data, and sometimes error detection information.
Q
QPSK
Quadruple phase shift keying is a modulation technique used by IEEE
802.11b-compliant wireless LANs for transmission at 2 Mbps.
R
range
A linear measure of the distance that a transmitter can send a signal.
