I-802.11n imilinganiselo yoshishino lwe-IEEE yezonxibelelwano zonxibelelwano zentambo zangaphandle ze-Wi-Fi , ezivunyiweyo ngo-2009. I-802.11n yenzelwe ukubuyisela ubuchwepheshe be- Wi-Fi engama- 802.11a , 802.11b kunye no- 802.11g .
Iikhompyutheni ezingenantambo ezingundoqo kwi-802.11n
I-802.11n isebenzisa ii-antenna ezininzi ezingenazintambo kwi-tandem yokuhambisa nokufumana idatha. I- MIMO yexesha elidibeneyo (i-Multiple Input, I-Multiple Output) ibhekisela kumandla ka-802.11n kunye nobuchwepheshe obufanayo ukudibanisa amanqaku amaninzi atshoni. I-MIMO iphakamisa zombini udidi kunye nokugqithiswa kwenethiwekhi engenazintambo.
Iprojekthi eyongeziweyo eqeshwe ngu-802.11n ibandakanya ukwandisa umda womda wokuhamba. Njengoko ku-802.11a / b / g ukunxibelelana, nganye nganye .11nowesixhobo isebenzisa isistim e-Wi-Fi esetyenziswe kuyo. Ngamnye umgca we -11n uya kusebenzisa ibanga leenqabileyo ezininzi kunemilinganiselo yangaphambili, kwaye ukwandisa ukuphuma kwedatha.
802.11n Ukusebenza
Ukuxhaswa kwama-802.11n ukuxhaswa komnatha womnatha wee-bandwidth ukuya kwi-300 Mbps ngokuxhomekeke ngokukodwa kwinani lee-radios ezingenazintambo ezifakwe kumacebo.
802.11n ngokubhekiselele kwi-Pre-N Equipment Equipment
Kwiminyaka embalwa edluleyo ngaphambi kokuba i-802.11n iqinisekiswe ngokusemthethweni, abavelisi bezixhobo zonxibelelwano bathengiswa oko kuthiwa yi- pre-N okanye i- draft N ezixhomekeke kwimirhumo yokuqala. Olu hlobo lwezinto eziphathekayo luhambelana ngokubanzi ne-802.11n gear, nangona uphuculo lwe-firmware kulezi zixhobo ezindala zingadingeka.
