802.11
IEEE 802.11 (
(PHY) specification for wireless connectivity for fixed, 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mostly superseded by 802.11b.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
local area networks.
802.11a
IEEE 802.11a (
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
Communications
5 GHz is IEEE 802.11a Turbo mode. Atheros Turbo 2.4 GHz is IEEE 802.11g Turbo mode.
802.11b
IEEE 802.11b (
5.5 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
