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.
An antenna that radiates its signal in a spherical pattern.
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.
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).
Any of several techniques for combining user information with a transmitter's
carrier signal.
The echoes created as a radio signal bounces off of physical objects.
A single data message (packet) sent to multiple addresses.
This typically refers to a primarily circular antenna radiation pattern.
Orthogonal frequency division multiplex is a
802.11a-compliant wireless LANs for transmission at 6, 9, 12, 18, 24, 36, 48,
and 54 Mbps.
A basic message unit for communication across a network. A packet usually includes routing
information, data, and sometimes error detection information.
Quadruple phase shift keying is a
802.11b-compliant wireless LANs for transmission at 2 Mbps.
