Term Definition
802.11 An evolving family of specifications for wireless LANs developed by a
working group of the Institute of Electrical and Electronics Engineers
(IEEE). 802.11 standards use the Ethernet protocol and CSMA/CA
(carrier sense multiple access with collision avoidance) for path sharing.
802.11a Provides specifications for wireless systems. Networks using 802.11a
operate at radio frequencies in the 5GHz band. The specification uses a
modulation scheme known as orthogonal frequency-division
multiplexing (OFDM) that is especially well suited to use in office
settings. The maximum data transfer rate is 54 Mbps.
802.11b WLAN standard often called Wi-Fi; backward compatible with 802.11.
Instead of the phase-shift keying (PSK) modulation method historically
used in 802.11 standards, 802.11b uses complementary code keying
(CCK), which allows higher data speeds and is less susceptible to
multipath-propagation interference. 802.11b operates in the 2.4 GHz
band and the maximum data transfer rate is 11 Mbps.
