GLOSSARY
802.3af
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.
802.11
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.
802.11a
The IEEE standard that specifies carrier sense media access control and physical
layer specifications for wireless LANs operating in the 5-GHz frequency band.
802.11b
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.
802.11g
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.
802.11n
An IEEE standard that builds upon previous 802.11 standards by adding MIMO
(multiple-input multiple-output). IEEE 802.11n offers high throughput wireless
transmission at 100Mbps – 200 Mbps.
A
access point
A wireless LAN data transceiver that uses radio waves to connect a wired
network with wireless stations.
ad hoc network
A wireless network composed of stations without access points.
AES-CCMP
Based on the Advanced Encryption Standard (AES) defined in the National
Institute of Standards and Technology’s FIPS Publication 197, AES-CCMP is a
symmetric block cipher that can encrypt and decrypt data using keys of 128, 192,
and 256 bits. AES-CCMP is superior to WEP encryption and is defined in the
IEEE 802.11i standard.
antenna gain
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.
