I-802.11 (ngezinye izikhathi ebizwa nge- 802.11x, kodwa hhayi 802.11X) igama elijwayelekile lomndeni wamazinga ezinethiwekhi zokuxhumana ezingenantambo ezihlobene ne- Wi-Fi .
Isikimu sokubala se-802.11 sivela ku-Institute of Electrical and Electronics Engineers (IEEE), esisebenzisa "i-802" njengegama lekomiti yamazinga enethiwekhi ahlanganisa i- Ethernet (IEEE 802.3). "11" ibhekisela kumanethiwekhi okusebenza angenazintambo (ama-WLAN) asebenzayo ngaphakathi kwekomidi lawo lama-802.
Amazinga we-IEEE 802.11 achaza imithetho ethile yokuxhumana kwe-WLAN. Amazinga aziwa kakhulu kulawa mazinga afaka 802.11g , 802.11n no- 802.11ac .
I-Standard First 802.11
I-802.11 (engenayo isisindo sombhalo) yayiyizinga eliyisisekelo kulo mndeni, elivunyelwe ngo-1997. I-802.11 yakha ukukhulumisana kwenethiwekhi yasendaweni engenantambo njengendlela ehlukile e-Ethernet. Ukuba ubuchwepheshe bokuzalwa kwesizukulwane sokuqala, i-802.11 inezilinganiso ezinkulu ezivimbela ukuba zingabonakali emikhiqizweni yezohwebo - amazinga wedatha, isibonelo, 1-2 Mbps . I-802.11 ivuselelwe masinyane futhi yenziwe ingasebenzi eminyakeni emibili yi- 802.11a no- 802.11b .
Ukuguquka kwe-802.11
Inombolo ngayinye entsha emndenini ka-802.11 (ovame ukubizwa ngokuthi "izichibiyelo") ithola igama ngezinhlamvu ezintsha ezixhunyiwe. Emva kwe-802.11a no-802.11b, kudalwe amazinga amasha, izizukulwane ezilandelanayo zezinhlelo zokuqala ze-Wi-Fi ezikhishwe ngale ndlela:
- I-802.11g (iqinisekiswe ngo-2003)
- I-802.11n (yavunyelwa ngo-2009)
- I-802.11ac (iqinisekiswe ngo-2013)
Ngokuhambisana nalezi zibuyekezo ezinkulu, iqembu le-IEEE 802.11 elisebenzayo lakhulisa ezinye izivumelwano ezihlobene nezinye izinguquko. Ngokuvamile i-IEEE ibeka amagama emaqenjini okusebenza ama-oda akhishwe ngaphandle kunesikhathi lapho izinga liphelile. Ngokwesibonelo:
- 802.11c - ukuxhumana kwe-bhuloho (kuhanjiswe ku-802.1D)
- 802.11d - ukuhambisana nomhlaba jikelele nemithethonqubo yokusetshenziswa kwe-spectrum signal spectrum (2001)
- 802.11e - Ukusekelwa kwekhwalithi ye-Quality ( Service ) (QoS) (2005-2007)
- I-802.11F - Isiphakamiso se-Inter-Access Protocol sokuxhumana phakathi kwamaphoyinti okufinyelela ekusekeleni amakhasimende okuzulazula (2003)
- 802.11h - inguqulo ethuthukisiwe ye-802.11a ukusekela izidingo zokulawula zaseYurophu (2003)
- 802.11i - ukuthuthukiswa kokuphepha komndeni wakwa-802.11 (2004)
- I-802.11j - izithuthukisi zokufaka ukufaka uphawu kwe-GHz ukuze zisekele izidingo zokulawula zaseJapane (2004)
- 802.11k - ukuphathwa kwe-WLAN uhlelo
- U-802.11l - weqe ukugwema ukudideka ngo-802.11i
- 802.11m - ukugcinwa kwemibhalo yomndeni ka-802.11
- I-802.11o - yeqa
- I-802.11p - Ukufinyelela okungenazintambo kwe-Vehicular Environment
- I-802.11q - yeqa
- 802.11r - ukwesekwa okusheshayo okuzulazula nge-Basic Service Set Transitions
- 802.11s - Ukuxhumana kwenethiwekhi ye-ESS yamaphoyinti okufinyelela
- 802.11T - Ukubikezelwa kokusebenza okungenantambo - isincomo sokulinganisa amazinga namethrikhi
- 802.11u - ukusebenza nge-inthanethi nge-3G / amaselula kanye nezinye izinhlobo zamanethiwekhi angaphandle
- 802.11v - ukuphathwa kwenethiwekhi yezingcingo / ukucushwa kwedivayisi
- 802.11w - Ukuthuthukiswa kokuvikeleka kwamafomu okuvikelwa okuvikelwe
- I-802.11x - yeqa (igama elijwayelekile lomndeni wakwa-802.11)
- I-802.11y - I-Protocol Based Contention yokuphepha kokuphazamiseka
I-Official Official IEEE 802.11 Ikhasi Lokusebenza Lekhasi Lokusebenza Lekhasi Lokusebenza lishicilelwa i-IEEE ukukhombisa isimo sezinga ngalinye elingenazintambo okwamanje elingaphansi kokuthuthukiswa.
