Glossary of Terms
802.11a
A supplement to the IEEE 802.11 WLAN specification that describes radio
transmissions at a frequency of 5 GHz and data rates of up to 54 Mbps.
802.11b
A supplement to the IEEE 802.11 WLAN specification that describes radio
transmissions at a frequency of 2.4 GHz and data rates of up to 11 Mbps.
802.11d
A supplement to the Media Access Control (MAC) layer in 802.11 to promote
worldwide use of 802.11 WLANs. It allows Access Points to communicate
information on the permissible radio channels with acceptable power levels for
user devices. Because the 802.11 standards cannot legally operate in some
countries, 802.11d adds features and restrictions to allow WLANs to operate
within the rules of these countries.
802.11g
A supplement to the IEEE 802.11 WLAN specification that describes radio
transmissions at a frequency of 2.4 GHz and data rates of up to 54 Mbps.
802.11n
A supplement to the IEEE 802.11 WLAN specification that describes
enhancements to 802.11a/b/g to greatly enhance reach, speed, and capacity.
802.1Q
An IEEE standard for MAC layer frame tagging (also known as encapsulation).
Frame tagging uniquely assigns a user-defined ID to each frame. It also enables a
switch to communicate VLAN membership information across multiple (and
multi-vendor) devices by frame tagging.
AES
(Advanced Encryption Standard) A data encryption scheme that uses three
different key sizes (128-bit, 192-bit, and 256-bit). AES was adopted by the U.S.
government in 2002 as the encryption standard for protecting sensitive but
unclassified electronic data.
