Glossary
The number used to identify the IP subnetwork, indicating whether the IP
IP subnet mask
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.
isotropic
M
Media Access Control address. A unique 48-bit number used in Ethernet data
MAC
packets to identify an Ethernet device, such as an access point or your client
adapter.
Any of several techniques for combining user information with a transmitter's
modulation
carrier signal.
The echoes created as a radio signal bounces off of physical objects.
