802.11n ndiyeso yodabwitsa ya IEEE ya Wi-Fi yopanda mauthenga a pa intaneti, omwe amavomerezedwa mu 2009. 802.11n yapangidwa kuti idzasinthe maluso apamwamba a 802.11a , 802.11b ndi 802.11g .
Makina Opanda Mafilimu Osayenerera mu 802.11n
802.11n amagwiritsa ntchito ma antenn angapo opanda waya pamtanda kuti adziwe ndi kulandira deta. MIMO yowonjezera (Multiple Input, Multiple Output) imatanthawuza luso la 802.11n ndi matekinoloje ofanana kuti agwirizanitse zizindikiro zamtunduwu panthawi yomweyo. MIMO imapanga zonse zowonjezera komanso zogwiritsira ntchito makina opanda waya.
Njira yowonjezera yomwe amagwiritsidwa ntchito ndi 802.11n ikuphatikizapo kukula kwa bandwidth. Mofanana ndi mautumiki a 802.11a / b / g, aliyense .11nthangizo imagwiritsa ntchito njira yowonongeka ya Wi-Fi yomwe mungapereke. Mtsinje uliwonse11 umatha kugwiritsa ntchito maulendo akuluakulu kuposa machitidwe oyambirirawa, komanso kuwonjezeranso kusinthika kwa deta.
Ntchito 802.11n
Kugwirizana kwa 802.11n kumathandizira pazomwe maofesi amtundu wa bandwidth kufika 300 Mbps molingana ndi chiwerengero cha ma radio opanda waya omwe amamangidwa mu zipangizo.
802.11n vs. Pre-N Network Equipment
Zaka zingapo zapitazo 802.11n isanayambe kuvomerezedwa, ogulitsa zipangizo zamagetsi anagulitsa zotchedwa zida za N-N kapena zowonjezeredwa N pogwiritsa ntchito zolemba zoyambirira zazomwezo. Zida zimenezi zimagwirizana ndi magetsi okwana 802.11n, ngakhale kuti zipangizo zamakonozi zingakhale zofunikira kwambiri.
