802.11 (ngamanye amaxesha ubizwa ngokuthi ngu- 802.11x, kodwa kungekhona i-802.11X) igama eliqhelekileyo lentsapho yemigangatho yokunxibelelana nge-wireless ehlobene ne- Wi-Fi .
Iskimu sokubala i-802.11 ivela kwiziko leeNjineli zombane kunye neZijoni (IEEE), elisebenzisa "i-802" njengegama lekomiti yemigangatho yokunxibelelana equka i- Ethernet (IEEE 802.3). "11" ibhekisela kumanethiwekhi asekuhlaleni angenazintambo (ii-WLAN) iqela eliphakathi kwekomiti yabo eyi-802.
IEEE 802.11 imigangatho ichaza imigaqo ethile yokunxibelelana kweWLAN. Eyona yaziwa kakhulu kule migangatho ibandakanya 802.11g , 802.11n kunye ne- 802.11ac .
Okokuqala 802.11 Umgangatho
I-802.11 (engenakho isisombululo sencwadi) yayiyimilinganiselo yasekuqaleni kule ntsapho, yavunyelwa ngo-1997. 802.11 isetyenziselwa ukuxhulumana kwenethiwekhi yangasese engena-wire njengendlela enye e-Ethernet. Ukuba yi-teknoloji yesizukulwana sokuqala, i-802.11 yayineemida ezinzulu ezazikhusela ukuba zingabonakali kwimveliso yorhwebo - amaxabiso eedatha, umzekelo, 1-2 Mbps . I-802.11 iphuculwe ngokukhawuleza kwaye yenziwe ingasebenzi kwisithuba seminyaka emibini ngama- 802.11a no- 802.11b .
Evolution 802.11
Umgangatho ngamnye omtsha ngaphakathi kwintsapho ka-802.11 (ebizwa rhoqo ngokuthi "izilungiso") ufumana igama ngeencwadi ezitsha ezixhaswayo. Emva kwe-802.11a no-802.11b, kuye kwadalwa imigangatho emitsha, izizukulwana ezilandelelanayo zeenkqubo eziphambili ze-Wi-Fi ezikhutshwe kule ndlela:
- 802.11g (yavunywa ngo-2003)
- 802.11n (yamkelwe ngo-2009)
- 802.11ac (yamkelwe ngo-2013)
Ngokuhambelanayo nale mihla yokuhlaziywa enkulu, iqela lasebenzayo le-IEEE 802.11 lenze ezinye iinkqubo ezihlobene kunye nezinye iinguqulelo. IEEE ngokubanzi ikwabela amagama kumacandelo okusebenza amacandelo athathwe ngaphandle kunokuba umgangatho upheleleyo. Umzekelo:
- 802.11c - usebenziso lweebrari ezixhunyiwe (ezifudukela kwi-802.1D)
- 802.11d - ukuthotyelwa kwehlabathi jikelele kwimimiselo yokusetyenziswa kwesigxina se-wireless signal (2001)
- 802.11e - Inkxaso yeNqanaba leNkonzo (QoS) (2005-2007)
- I-802.11F - Isiphakamiso seProtokholi yoPhulo lwe-Inter-Interface yokunxibelelana phakathi kwamanqaku okufikelela ekuxhaseni abaxumi bezithuthi (2003)
- 802.11h - inguqu ephuculweyo ye-802.11a ukuxhasa iimfuno zolawulo lwaseYurophu (2003)
- 802.11i - ukuphucula ukhuseleko lweentsapho ezingama-802.11 (2004)
- 802.11j - izithuthukisi ukuya kwi-5 GHz yokubonisa ukuxhasa iimfuno zolawulo lwaseJapan (2004)
- 802.11k - Ulawulo lwe-WLAN
- I-802.11l - yehliswa ukuze iphephe ukudideka kunye ne-802.11i
- 802.11m - ukugcinwa kwamaxwebhu omndeni ka-802.11
- 802.11o - wehliswa
- 802.11p - Ukufikelela kwi-Wireless kwi-Vehicular Environment

- 802.11r - inkxaso yokuzula ngokukhawuleza nge-Basic Service Setting
- I-802.11s - I-ESS yokunxibelelana kweetayitile zeendawo zokufikelela
- I-802.11T - Ukunikezelwa kokuSebenza okungenazintambo - isincomo kwimilinganiselo yokuvavanya kunye neemitha
- 802.11u - intsebenziswano nge-intanethi kunye ne-3G / iselula kunye nezinye iindlela zokunxibelelanisa zangaphandle
- 802.11v - ukuphathwa kwenethiwekhi / ukucwangciswa kwedivayisi
- I-802.11w - Ukuphuculwa koKhuselo loLondolozo lweNkqubo
- I-802.11x - i-skipped (igama lobudala kwiintsapho ezingama-802.11)
- I-802.11y - I-Protocol Based Based Protocol yokuphazamiseka kokuphazamiseka
I-Official Official IEEE 802.11 Iprojekthi yeQela lokuSebenza lePhepha eliPhezulu lipapashwa ngu-IEEE ukubonisa isimo somgangatho ngamnye ongenazintambo okwangoku uphuhliso.
