802.11n igomba gusobanurwa ukwayo. Kugeza ubu, isoko nyamukuru ikoresha iyi protocole yo kohereza WiFi.
802.11n ni protocole isanzwe yoherejwe. Nubuhanga bukora ibihe. Isura yayo ituma igipimo cyimiyoboro idafite umugozi cyiyongera cyane. Mu rwego rwo kunoza ibipimo bibiri byabanjirije umuyoboro udafite insinga, harimo no guhuza imiyoboro hamwe n’ibura ry’umuhanda wa 802.11a na 802.11g.
Umuvuduko wacyo ntarengwa ni 600 Mbit / s mubitekerezo, ariko ntishobora kugera kumuvuduko mwinshi mubikorwa kubera ibidukikije nibishushanyo mbonera. Ugereranije na 54mbit / s zabanjirije iyi, iratera imbere cyane kandi intera yoherejwe nayo iziyongera.
Itsinda ry’imirimo rya IEEE 802.11 ryashyizeho itsinda ry’ubushakashatsi ryinjira cyane (HT) mu 2002 kugira ngo rishyireho igisekuru gishya cy’ibipimo, kandi ritangaza ku mugaragaro 802.11n rishingiye kuri MIMO-OFDM mu 2009. Ikintu gikomeye ni uko cyateye intambwe. ku gipimo.
802.11 ikoresha tekinolojiya mishya itandukanye, izana abayikoresha akarere-gashya k'uburambe. Muri iyi protocole, inganda za WLAN zateye imbere cyane, kandi igitekerezo cya WiFi cyashinze imizi. Kugeza ubu, umubare munini wa 802.11n terminal uracyakoreshwa murusobe.
802.11n tekinoroji itahura umurongo mugari kandi izana ibintu byinshi kuri porogaramu kuri WiFi.
802.11n yazanye tekinoroji nshya. Muri 802.11n, kwinjiza tekinoroji ya WLAN byatejwe imbere byuzuye muguhuza optimizme yumubiri na MAC layer. MIMO yateguwe na tekinoroji yumubiri irakomeye cyane. MIMO-OFDM 40MHz hamwe na tekinoroji ya GI ikoreshwa mugutezimbere kwinjiza urwego rwumubiri kugeza kuri 600mbps.
GI bivuze ko, bitewe ningaruka zingaruka zinyuranye, amakuru azoherezwa munzira nyinshi, zishobora kugongana kandi biganisha kuri intersymbol. Kubera iyo mpamvu, 802.11a / g igipimo gisaba ko mugihe wohereje ibimenyetso byamakuru, hagomba kubaho intera ya 0.8us hagati yikimenyetso cyamakuru, bita intera yo kurinda.
Usibye kurwego rwo hejuru rwogutezimbere, 802.11n inanonosora urwego rwa protocole ya MAC, ukoresheje blok ya ACK, guteranya ikadiri, hamwe nubundi buryo bwikoranabuhanga, bitezimbere cyane imikorere ya MAC. Gusa urwego rwumubiri rutezimbere niba MAC layer protocole idakozwe neza. Ninko kubaka umuhanda mugari, ariko ntirihuta hatabayeho gahunda nziza.
Ibyavuzwe haruguru ni ieee802.11n ibisobanuro byubumenyi byazanwe naweShenzhen HDV Phoelectron Technology Co., Ltd.. twizere ko iyi ngingo ishobora kugufasha kongera ubumenyi. Usibye iyi ngingo niba ushaka ibikoresho byiza bya fibre itumanaho ibikoresho bya sosiyete ushobora gutekerezaibyerekeye twe.
Ibicuruzwa byitumanaho byakozwe nisosiyete ikora:

Ibicuruzwa byavuzwe haruguru birashobora gushigikira imiyoboro itandukanye. Kubicuruzwa byavuzwe haruguru, itsinda ryumwuga kandi rikomeye R & D ryahujwe no gutanga ubufasha bwa tekinike kubakiriya, kandi itsinda ryubucuruzi ryatekereje kandi ryumwuga rirashobora gutanga serivise nziza kubakiriya hakiri karekugisha inamahanyuma nyuma.
