Term Definition
802.11 An evolving family of specifications for w ireless LANsdeveloped bya w orking
groupof the Institute of Electrical and Electronics Engineers (IEEE). 802.11
standardsuse the Ethernet protocol and CSMA/CA (carrier sensem ultiple access
with collision avoidance) for path sharing.
802.11a Providesspecifications for w ireless systems.Networks using 802.11a operate at
radio frequenciesi n the5GHz band. The specification uses a modulation scheme
knownas orthogonal frequency-divisionmultipl exing (OFDM)that is especially w ell
suitedto use in office settings.
802.11b WLANstandard often called Wi-Fi; backward com patible with 802.11.Instead of
thephase-shift keying (PSK) modulation method historically used in 802.11
standards,802.11b uses complementary code keying (CCK), w hich allows higher
dataspeeds and is less susceptible to multipath-propagation interference.
802.11d Awi reless network communications specification for use in countries where
systemsusing other standards in the 802.11family are not allowed to operate.
