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
LANS 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.
