The IEEE standard that specifies carrier sense media access control and physical layer
specifications for 1- and 2-megabit-per-second (Mbps) wireless LANs operating in the 2.4-GHz
band.
The IEEE standard that specifies carrier sense media access control and physical layer
specifications for wireless LANs operating in the 5-GHz frequency band.
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.
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.
Boot Protocol. A protocol used for the static assignment of IP addresses to devices on the network.
A wireless LAN transceiver that is used to interconnect two or more wired Ethernet networks.
A single data message (packet) sent to all addresses on the same subnet.
The area of radio range or coverage in which the wireless devices can communicate with the base
station. The size of the cell depends upon the speed of the transmission, the type of antenna used,
and the physical environment, as well as other factors.
Carrier sense multiple access. A wireless LAN media access method specified by the IEEE 802.11
specification.
