802
IEEE 802 (IEEE Std. 802-2001) is a family of
standards for peer-to-peer communication over a
LAN. These technologies use a shared-medium, with
information broadcast for all stations to receive. The
basic communications capabilities provided are
packet-based. The basic unit of transmission is a
sequence of data octets (8-bits), which can be of any
length within a range that is dependent on the type of
LAN.
Included in the 802 family of
definitions of bridging, management, and security
protocols.
802.1X
IEEE 802.1X (IEEE Std.
for passing EAP packets over an
network using a protocol called EAP Encapsulation
Over LANs (EAPOL). It establishes a framework that
supports multiple authentication methods.
IEEE 802.1X authenticates users not machines.
802.2
IEEE 802.2 (IEEE Std. 802.2.1998) defines the
layer for the 802 family of standards.
802.3
IEEE 802.3 (IEEE Std. 802.3-2002) defines the
MAC layer for networks that use CSMA/CA.
Ethernet is an example of such a network.

802.11-1999) is a medium
portable, and moving stations within a local area. It
uses direct sequence spread spectrum (DSSS) in the
2.4 GHz ISM band and supports raw data rates of 1
and 2 Mbps. It was formally adopted in 1997 but has
been mostly superseded by 802.11b.
IEEE 802.11 is also used generically to refer to the
family of IEEE standards for wireless local area
networks.
802.11a
IEEE 802.11a (IEEE Std.
standard that specifies operating in the 5 GHz U-NII
band using orthogonal frequency division
multiplexing (OFDM). It supports data rates ranging
from 6 to 54 Mbps.
802.11a Turbo
IEEE 802.11a Turbo is a proprietary variant of the
802.11a standard from Atheros
supports accelerated data rates ranging from 6 to
108Mbps. Atheros Turbo 5 GHz is IEEE 802.11a
Turbo mode. Atheros Turbo 2.4 GHz is IEEE
802.11g Turbo mode.
802.11b
IEEE 802.11b (IEEE Std.
enhancement of the initial
Mbps and 11 Mbps data rates. It uses direct sequence
spread spectrum (DSSS) or frequency hopping
spread spectrum (FHSS) in the 2.4 GHz ISM band as
well as complementary code keying (CCK) to
provide the higher data rates. It supports data rates
ranging from 1 to 11 Mbps.
802.11d
IEEE 802.11d defines standard rules for the
operation of IEEE 802.11 wireless LANs in any
country without reconfiguration. PHY requirements
such as provides frequency hopping tables,
acceptable channels, and power levels for each
country are provided. Enabling support for IEEE
802.11d on the access point causes the AP to
broadcast which country it is operating in as a part of
its beacons. Client stations then use this information.
This is particularly important for AP operation in the
5GHz IEEE 802.11a bands because use of these
