Ubwino wa WIFI 6 ONT

Poyerekeza ndi mibadwo yakale yaukadaulo wa WiFi, mbali zazikulu za m'badwo watsopano wa WiFi 6 ndi:
Poyerekeza ndi m'badwo wam'mbuyo wa 802.11ac WiFi 5, kuchuluka kwa kufalikira kwa WiFi 6 kwawonjezeka kuchokera ku 3.5Gbps yakale mpaka 9.6Gbps, ndipo liwiro lachidziwitso lawonjezeka pafupifupi nthawi za 3.
Pankhani ya ma frequency band, WiFi 5 imakhudza 5GHz yokha, pomwe WiFi 6 imaphimba 2.4/5GHz, yophimba kwathunthu zida zotsika komanso zothamanga kwambiri.
Pankhani yosinthira, WiFi 6 imathandizira 1024-QAM, yomwe ndi yapamwamba kuposa 256-QAM ya WiFi 5, ndipo ili ndi kuchuluka kwa data, zomwe zikutanthauza kuthamanga kwapa data.

M'munsi latency
WiFi 6 sikungowonjezera kuchuluka kwa kutsitsa ndi kutsitsa, komanso kusintha kwakukulu pakusokonekera kwa maukonde, kulola zida zambiri kuti zilumikizidwe ndi netiweki opanda zingwe ndikukhala ndi kulumikizana kothamanga kwambiri, komwe kumachitika makamaka chifukwa cha MU- MIMO. ndi OFDMA matekinoloje atsopano.
Muyezo wa WiFi 5 umathandizira ukadaulo wa MU-MIMO (ma multi-user-input multiple-output), womwe umangothandizira downlink, ndipo umatha kukumana ndi ukadaulo uwu potsitsa zomwe zili.WiFi 6 imathandizira uplink ndi downlink MU-MIMO, zomwe zikutanthauza kuti MU-MIMO imatha kudziwa mukatsitsa ndikutsitsa zidziwitso pakati pa zida zam'manja ndi ma router opanda zingwe, kupititsa patsogolo kagwiritsidwe ntchito ka bandwidth yama network opanda zingwe.
Kuchuluka kwa mitsinje ya data yapamlengalenga yomwe imathandizidwa ndi WiFi 6 yawonjezeka kuchokera ku 4 mu WiFi 5 mpaka 8, ndiko kuti, imatha kuthandizira 8 × 8 MU-MIMO, chomwe ndi chimodzi mwazifukwa zofunika pakuwonjezeka kwakukulu kwa mtengo wa WiFi 6.
WiFi 6 imagwiritsa ntchito ukadaulo wa OFDMA (Orthogonal Frequency Division Multiple Access), womwe ndi mtundu wosinthika waukadaulo wa OFDM womwe umagwiritsidwa ntchito mu WiFi 5. Imaphatikiza ukadaulo wa OFDM ndi FDMA.Pambuyo pogwiritsira ntchito OFDM kuti asinthe tchanelo kukhala chonyamulira makolo, ma subcarriers ena Ukadaulo wotumizira wotsitsa ndi kutumiza deta umalola ogwiritsa ntchito osiyanasiyana kugawana njira yomweyo, kulola zida zambiri kuti zitheke, ndi nthawi yoyankha yayifupi komanso kuchedwa kochepa.

Kuonjezera apo, WiFi 6 imagwiritsa ntchito njira yotumizira Chizindikiro cha Long DFDM kuti iwonjezere nthawi yotumizira chizindikiro chilichonse kuchokera ku 3.2 μs mu WiFi 5 mpaka 12.8 μs, kuchepetsa kutayika kwa paketi ndi kubwezeretsanso, ndikupangitsa kuti kupatsirana kukhale kokhazikika.

Kuthekera kwakukulu
WiFi 6 imayambitsa makina a BSS Coloring, ndikuyika chizindikiro pa chipangizo chilichonse cholumikizidwa ndi netiweki, ndikuwonjezera zilembo zofananira ndi data yake nthawi imodzi.Potumiza deta, pali adilesi yofananira, ndipo imatha kupatsirana mwachindunji popanda chisokonezo.

Ukadaulo wa ogwiritsa ntchito angapo a MU-MIMO umalola ma terminals angapo kugawana tchanelo cha nthawi ya netiweki yamakompyuta, kuti mafoni/makompyuta angapo azitha kuyang'ana pa intaneti nthawi imodzi.Kuphatikizidwa ndi ukadaulo wa OFDMA, njira iliyonse pansi pa netiweki ya WiFi 6 imatha kutumiza mwachangu kwambiri, kuwongolera ogwiritsa ntchito ambiri. kuzizira, ndipo mphamvu ndi yokulirapo.

Otetezeka
Ngati chipangizo cha WiFi 6 (chopanda zingwe) chiyenera kutsimikiziridwa ndi WiFi Alliance, chiyenera kutengera WPA 3 protocol protocol, yomwe ndi yotetezeka kwambiri.
Kumayambiriro kwa 2018, WiFi Alliance idatulutsa m'badwo watsopano wa WiFi encryption protocol WPA 3, womwe ndi mtundu wosinthidwa wa protocol ya WPA 2 yomwe imagwiritsidwa ntchito kwambiri.Chitetezo chimakulitsidwanso bwino, ndipo chimatha kuteteza bwino kuukira kwa brute force and brute force cracking.
kupulumutsa mphamvu zambiri
WiFi 6 imayambitsa ukadaulo wa TARget Wake Time (TWT), womwe umalola kukonzekera nthawi yolumikizana pakati pa zida ndi ma routers opanda zingwe, kuchepetsa kugwiritsa ntchito tinyanga opanda zingwe ndi nthawi yosaka ma siginecha, zomwe zimatha kuchepetsa kugwiritsa ntchito mphamvu pamlingo wina ndikuwongolera batire la chipangizocho. moyo.

HUANET imapereka WIFI 6 ONT, ngati mukufuna, pls tilankhule nafe.
