I-802.11n iyizinga elijwayelekile lemikhiqizo ye-IEEE yokuxhumana kwenethiwekhi yendawo ye-Wi-Fi engenazintambo, okwavunyelwa ngo-2009. I-802.11n yakhelwe ukufaka esikhundleni kobuchwepheshe obudala be- 802.11a , 802.11b no- 802.11g .
Izinkampani ezingenantambo ezingenantambo ku-802.11n
I-802.11n isebenzisa ama-antenna amaningi angenantambo ngokulandelana ukuze adlulise futhi athole idatha. Isikhathi esihambisanayo se- MIMO (Iningi Lokufaka, I-Multiple Output) libhekisela emandleni we-802.11n nobuchwepheshe obufanayo ukuxhumanisa izikhangiso eziningi zomsakazo ngesikhathi esisodwa. I-MIMO iphakamisa kokubili ububanzi nokudluliswa kwenethiwekhi engenantambo.
Inqubo eyengeziwe eqashwe ngu-802.11n ihilela ukwandisa umkhawulokudonsa wesiteshi. Njengokwenethiwekhi ye-802.11a / b / g, ngayinye .Idivaysi engu-11 isebenzisa isiteshi se-Wi-Fi esethiwe esingazithumela kuso. Ngamunye umzila wesiteshi esingu -11 uzosebenzisa ibanga lemiphakathi ekhudlwana kunelawa mazinga okuqala, futhi ukwandisa ukuphuma kwedatha.
Umsebenzi we-802.11n
Ukuxhumeka kwama-802.11n kusekela umkhawulokudonsa womthamo we-network ophezulu kuya ku-300 Mbps ngokuya ngokuyinhloko kumanethiwekhi angenawaya ahlanganiswe kumadivayisi.
I-802.11n vs. I-Pre-N Equipment Equipment
Eminyakeni embalwa edlule ngaphambi kokuba u-802.11n uqinisekiswe ngokomthetho, abakhiqizi bemishini yensiza bathengiswa okuthiwa ama- pre-N noma ama- draft we-N ngokusekelwe emibhalweni yokuqala. Le hardware ivame ukuhambisana ne-802.11n gear yamanje, nakuba ukuthuthukiswa kwe-firmware kulawa madivayisi amadala kungadingeka.
