The IEEE standard that describes a mechanism for Power over Ethernet (PoE). The
standard provides the capability to deliver both power and data over standard
Ethernet cabling.
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.
The IEEE standard that specifies carrier sense media access control and physical
layer specifications for 5.5- and 11-Mbps wireless LANs operating in the
2.4-GHz frequency band.
The IEEE standard that specifies carrier sense media access control and physical
layer specifications for 6, 9, 12, 18, 24, 36, 48, and 54 Mbps wireless LANs
operating in the 2.4-GHz frequency band.
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.
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.
