Uru nke WIFI 6 ONT

Ma e jiri ya tụnyere ọgbọ ndị gara aga nke teknụzụ WiFi, isi ihe dị na ọgbọ ọhụrụ nke WiFi 6 bụ:
Ma e jiri ya tụnyere ọgbọ gara aga nke 802.11ac WiFi 5, amụbaala ọnụego nnyefe kachasị elu nke WiFi 6 site na 3.5Gbps nke mbụ ruo 9.6Gbps, ọsọ echiche amụbaala ihe fọrọ nke nta ka ọ bụrụ ugboro atọ.
Maka usoro mgbasa ozi ugboro ugboro, WiFi 5 na-agụnye naanị 5GHz, ebe WiFi 6 na-ekpuchi 2.4/5GHz, na-ekpuchi ngwaọrụ dị obere ọsọ na nke dị elu nke ọma.
N'ihe gbasara ụdị mgbanwe, WiFi 6 na-akwado 1024-QAM, nke dị elu karịa 256-QAM nke WiFi 5, ma nwee ikike data dị elu, nke pụtara na ọ na-agba ọsọ nnyefe data dị elu.

Nkwụsị dị ala
WiFi 6 abụghị naanị mmụba na ọnụego mbugo na nbudata, kamakwa ọ bụ mmụba dị ukwuu na mkpọchi netwọk, na-enye ohere ka ọtụtụ ngwaọrụ jikọọ na netwọk ikuku ma nwee ahụmịhe njikọ dị elu na-aga n'ihu, nke bụ isi n'ihi teknụzụ ọhụrụ MU-MIMO na OFDMA.
Ọkọlọtọ WiFi 5 na-akwado teknụzụ MU-MIMO (ọtụtụ ndị ọrụ nwere ọtụtụ ntinye ọtụtụ mmepụta), nke na-akwado naanị njikọ ala, ọ na-enwekwa ike ịnweta teknụzụ a naanị mgbe ebudatara ọdịnaya. WiFi 6 na-akwado ma njikọ elu na njikọ ala MU-MIMO, nke pụtara na enwere ike ịnweta MU-MIMO mgbe ebudatara ma budata data n'etiti ngwaọrụ mkpanaka na rawụta ikuku, na-eme ka ojiji bandwit nke netwọk ikuku ka mma.
A mụbara ọnụọgụgụ data kachasị elu nke WiFi 6 na-akwado site na 4 na WiFi 5 ruo 8, ya bụ, ọ nwere ike ịkwado 8×8 MU-MIMO, nke bụ otu n'ime ihe dị mkpa kpatara mmụba dị ukwuu na ọnụego WiFi 6.
WiFi 6 na-eji teknụzụ OFDMA (Orthogonal Frequency Division Multiple Access), nke bụ ụdị teknụzụ OFDM e mepụtara na WiFi 5. Ọ na-ejikọta teknụzụ OFDM na FDMA. Mgbe ejiri OFDM gbanwee ọwa ahụ ka ọ bụrụ onye na-ebu ibu nne na nna, ụfọdụ ndị na-ebu ibu. Nkà na ụzụ nnyefe nke ibugo na izipu data na-enye ndị ọrụ dị iche iche ohere ịkekọrịta otu ọwa ahụ, na-enye ohere ka ọtụtụ ngwaọrụ nweta, yana obere oge nzaghachi na obere igbu oge.

Tinyere nke ahụ, WiFi 6 na-eji usoro nnyefe akara Long DFDM iji mee ka oge nnyefe nke onye na-ebu ihe mgbaàmà ọ bụla si na 3.2 μs na WiFi 5 ruo 12.8 μs, na-ebelata ọnụego mfu ngwugwu na ọnụego nnyefe ọzọ, ma na-eme ka nnyefe ahụ kwụsie ike.

Ike ka ukwuu
WiFi 6 na-ewebata usoro agba BSS, na-akara ngwaọrụ ọ bụla ejikọtara na netwọk ahụ akara, ma na-agbakwụnye akara ndị kwekọrọ na data ya n'otu oge. Mgbe ị na-ezipụ data, enwere adreesị kwekọrọ, enwere ike izipu ya ozugbo na-enweghị mgbagwoju anya.

Teknụzụ MU-MIMO nke nwere ọtụtụ ndị ọrụ na-enye ohere ka ọtụtụ ọdụ kesaa oge nke netwọk kọmputa, ka ọtụtụ ekwentị mkpanaaka/kọmputa wee nwee ike ịbanye na ịntanetị n'otu oge. Tinyere teknụzụ OFDMA, ọwa ọ bụla dị n'okpuru netwọk WiFi 6 nwere ike ịrụ ọrụ nnyefe data dị elu, na-eme ka ọtụtụ ndị ọrụ ka mma. Ahụmịhe netwọk dị na ebe ahụ nwere ike imezu ihe achọrọ nke ebe WiFi na-ekpo ọkụ, ojiji ọtụtụ ndị ọrụ, ọ dịghịkwa mfe ifriizi, ikike ya dịkwa ukwuu.

Nchekwa karịa
Ọ bụrụ na ngwaọrụ WiFi 6 (rawụta ikuku) chọrọ asambodo site na WiFi Alliance, ọ ga-enwerịrị usoro nchekwa WPA 3, nke dị nchebe karịa.
Ná mmalite nke afọ 2018, WiFi Alliance wepụtara ọgbọ ọhụrụ nke protocol nzuzo WiFi WPA 3, nke bụ ụdị emelitere nke protocol WPA 2 ejiri mee ihe nke ukwuu. A kawanye mma nchekwa ahụ, ọ nwekwara ike igbochi mwakpo ike brute na mgbawa ike brute nke ọma.
nchekwa ike karịa
WiFi 6 na-ewebata teknụzụ TARget Wake Time (TWT), nke na-enye ohere ịhazi oge nkwukọrịta n'etiti ngwaọrụ na rawụta ikuku, na-ebelata ojiji nke antenna netwọk ikuku na oge nchọta akara, nke nwere ike ibelata oriri ike ruo n'ókè ụfọdụ ma melite ndụ batrị ngwaọrụ.
