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.
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.
802.11d A wireless network communications specification for use in countries
where systems using other standards in the 802.11 family are not
allowed to operate. Configuration can be fine-tuned at the Media
Access Control layer (MAC layer) level to comply with the rules of the
country or district in which the network is to be used. Rules subject to
variation include allowed frequencies, allowed power levels, and
allowed signal bandwidth. 802.11d facilitates global roaming.
802.11e A proposed adaptation to the 802.11a and 802.11b specifications that
enhances the 802.11 Media Access Control layer (MAC layer) with a
coordinated time division multiple access (TDMA) construct, and adds
error-correcting mechanisms for delay-sensitive applications such as
voice and video. The 802.11e specification provides seamless
interoperability between business, home, and public environments such
as airports and hotels and offers all subscribers high-speed Internet
access with full-motion video, high-fidelity audio, and Voice over IP
(VoIP).
