802.11 (dzimwe nguva inonzi 802.11x, asi kwete 802.11X) ndiro zita rechimiro yemhuri yemitambo yekunamatira mitambo yakasangana ne Wi-Fi .
Chirongwa chokuverenga che 802.11 chinobva kuIsimba re Electrical and Electronics Engineers (IEEE), iro rinoshandisa "802" sezita rekomiti yekubatanidza mitemo inosanganisira Ethernet (IEEE 802.3). "11" inoreva nzvimbo dzisingabatsiri dzenharaunda dzenharaunda (WLANs) boka rekushandira mukati mavo 802 komiti.
IEEE 802.11 mitemo inotsanangura mitemo yakananga yeWLAN yokukurukura. Zvinonyanya kuzivikanwa pane izvi zvinosanganisira 802.11g , 802.11n uye 802.11ac .
Yokutanga 802.11 Standard
802.11 (isina nhamba yakakwana) ndiyo yaiva yepakutanga mumhuri iyi, yakagamuchirwa muna 1997. 802.11 yakagadzirwa kusina wireless munharaunda yekukurukurirana senzira yakasiyana yeEthernet. Kuva chizvarwa chekutanga tekombiki, 802.11 yakanga ine zvipingamupinyi zvakakomba zvakadzivirira kuti zvirege kuonekwa mumitambo yezvokutengeserana - dhidha yepamusoro, semuenzaniso, 1-2 Mbps . 802.11 yakakurumidza kugadziriswa uye yakagadziriswa mukati memakore maviri neyese 802.11a uye 802.11b .
Evhangeri ye 802.11
Imwe neimwe mitemo itsva mumhuri ye802.11 (inowanzonzi "kugadziriswa") inogamuchira zita nematsamba matsva akashandiswa. Pashure pe 802.11a uye 802.11b, maitiro matsva akaumbwa, zvizvarwa zvinotevera zvezvinyorwa zvekutanga zveW-Fi zvakabudiswa kurongwa uku:
- 802.11g (yakagamuchirwa muna 2003)
- 802.11n (yakagamuchirwa muna 2009)
- 802.11ac (yakagamuchirwa muna 2013)
Mukufananidza neidzo idzi dzinoshandiswa, IEEE 802.11 boka rekushanda rakagadzira dzimwe nhepfenyuro dzakawanda dzakabatana nedzimwe shanduko. IEEE inowanzopa mazita muhurongwa hwekuti mapoka ekushanda anongororwa panzvimbo apo kana mutemo wapera. Semuyenzaniso:
- 802.11c - kushanda kwebhiriji kuwirirana (kutamira kune 802.1D)

- 802.11y - Contention Based Protocol yekupindira kusabatwa
IOEEE 802.11 Peji yeKushanda Yeboka Project Peji Timeline yakabudiswa neIEEE kuratidzira mamiriro ehutano husina maturo iye zvino ari pasi pekugadzirwa.
