access point

ad hoc network

antenna gain

associated

A wireless LAN data transceiver that uses radio waves to connect a wired network with wireless stations.

A wireless network composed of stations without Access Points.

The gain of an antenna is a measure of the antenna’s ability to direct or focus radio energy over a region of space. High gain antennas have a more focused radiation pattern in a specific direction.

A station is configured properly to allow it to wirelessly communicate with an Access Point.

B

beacon

A wireless LAN packet that signals the availability and presence of the wireless

 

device. Beacon packets are sent by access points and base stations; however,

 

client radio cards send beacons when operating in computer to computer (Ad

 

Hoc) mode.

BOOTP

BPSK

Boot Protocol. A protocol used for the static assignment of IP addresses to devices on the network.

A modulation technique used by IEEE 802.11b-compliant wireless LANs for transmission at 1 Mbps.

broadcast packet A single data message (packet) sent to all addresses on the same subnet.
