A device that connects two otherwise incompatible networks together.
Gigahertz. One billion cycles per second. A unit of measure for frequency.
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.
The wired Ethernet network.
The Internet Protocol (IP) address of a station.
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 360 degrees both vertically and horizontally in a perfect sphere.
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.
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.
A wireless LAN transceiver connected to a remote Ethernet network and communicates only with
another wireless LAN transceiver connected to the main Ethernet network.
This typically refers to a primarily circular antenna radiation pattern.
A modulation technique used by IEEE 802.11a-compliant wireless LANs for transmission at 6, 9,
12, 18, 24, 36, 48, and 54 Mbps.
