Term Definition
802.11
The 802.11 standard refers to a family of specifications developed by the
IEEE for wireless LAN technology. The 802.11 specifies an over-the-air
interface between a wireless client and a base station or between two
wireless clients and provides 1 or 2 Mbps transmission in the 2.4 GHz
band using either frequency hopping spread spectrum (FHSS) or direct
sequence spread spectrum (DSSS).
802.11a
The 802.11a standard specifies a maximum data transfer rate of 54 Mbps
and an operating frequency of 5 GHz. The 802.11a standard uses the
Orthogonal Frequency Division Multiplexing (OFDM) transmission
method. Additionally, the 802.11a standard supports 802.11 features such
as WEP encryption for security.
802.11b
802.11b is an extension to 802.11 that applies to wireless networks and
provides 11 Mbps transmission (with a fallback to 5.5, 2 and 1 Mbps) in
the 2.4 GHz band. 802.11b uses only DSSS. Throughput data rate 5+
Mbps in the 2.4 GHz band.
802.11g
The 802.11g standard specifies a maximum data transfer rate of 54 Mbps,
an operating frequency of 2.4GHz, and WEP encryption for security.
802.11g networks are also referred to as Wi-Fi* networks.
802.11n
A task group of the IEEE 802.11 committee has defined a new draft
specification that provides for increased throughput speeds of up to 540
Mbps. The specification provides for Multiple-Input-Multiple-Output
(MIMO) technology, or using multiple receivers and multiple
transmitters in both the client and access point, to achieve improved
performance.
