Piv nrog rau tiam dhau los ntawm WiFi thev naus laus zis, cov yam ntxwv tseem ceeb ntawm lub cim tshiab ntawm WiFi 6 yog:
Piv nrog rau tiam dhau los ntawm 802.11ac WiFi 5, qhov siab tshaj plaws kis tau tus mob ntawm WiFi 6 tau nce los ntawm 3.5Gbps ntawm yav dhau los mus rau 9.6Gbps, thiab qhov theoretical ceev tau nce ze li 3 zaug.
Nyob rau hauv cov nqe lus ntawm cov zaus bands, WiFi 5 tsuas yog koom nrog 5GHz, thaum WiFi 6 npog 2.4/5GHz, tag nrho npog cov khoom siv qis thiab siab ceev.
Hais txog kev hloov pauv, WiFi 6 txhawb nqa 1024-QAM, uas siab dua 256-QAM ntawm WiFi 5, thiab muaj peev xwm ntau dua cov ntaub ntawv, uas txhais tau tias cov ntaub ntawv xa mus ceev dua.
Tsawg latency
WiFi 6 tsis yog tsuas yog nce tus nqi rub tawm thiab rub tawm xwb, tab sis kuj tseem muaj kev txhim kho tseem ceeb hauv network congestion, tso cai rau ntau yam khoom siv txuas mus rau lub wireless network thiab muaj kev sib txuas ceev ceev, uas feem ntau yog vim MU-MIMO. thiab OFDMA cov thev naus laus zis tshiab.
Lub WiFi 5 tus qauv txhawb nqa MU-MIMO (ntau tus neeg siv ntau qhov kev tawm tswv yim ntau-tso tawm) thev naus laus zis, uas tsuas yog txhawb nqa downlink, thiab tsuas yog tuaj yeem paub txog cov thev naus laus zis no thaum rub tawm cov ntsiab lus.WiFi 6 txhawb nqa ob qho tib si uplink thiab downlink MU-MIMO, uas txhais tau hais tias MU-MIMO tuaj yeem muaj kev paub txog thaum upload thiab rub tawm cov ntaub ntawv ntawm cov khoom siv mobile thiab wireless routers, ntxiv kev txhim kho kev siv bandwidth ntawm wireless networks.
Qhov siab tshaj plaws ntawm cov ntaub ntawv spatial kwj txhawb los ntawm WiFi 6 tau nce los ntawm 4 hauv WiFi 5 mus rau 8, uas yog, nws tuaj yeem txhawb nqa qhov siab tshaj plaws ntawm 8 × 8 MU-MIMO, uas yog ib qho tseem ceeb rau kev nce ntxiv hauv tus nqi ntawm WiFi 6.
WiFi 6 siv OFDMA (Orthogonal Frequency Division Multiple Access) thev naus laus zis, uas yog ib qho kev hloov pauv ntawm OFDM thev naus laus zis siv hauv WiFi 5. Nws ua ke OFDM thiab FDMA thev naus laus zis.Tom qab siv OFDM los hloov cov channel mus rau hauv niam txiv cov cab kuj, qee cov subcarriers Cov kev siv tshuab xa tawm thiab xa cov ntaub ntawv tso cai rau cov neeg siv sib txawv los sib koom tib lub channel, tso cai rau ntau cov khoom siv nkag mus, nrog lub sij hawm teb luv dua thiab qeeb qeeb.
Tsis tas li ntawd, WiFi 6 siv qhov ntev DFDM Cov cim kev sib kis tau los ua kom lub sijhawm sib kis ntawm txhua lub teeb liab los ntawm 3.2 μs hauv WiFi 5 mus rau 12.8 μs, txo cov pob ntawv poob thiab tus nqi xa rov qab, thiab ua rau kev sib kis tau zoo dua.
Muaj peev xwm loj dua
WiFi 6 qhia txog BSS Coloring mechanism, khij txhua lub cuab yeej txuas nrog lub network, thiab ntxiv cov ntawv sib txuas rau nws cov ntaub ntawv tib lub sijhawm.Thaum xa cov ntaub ntawv, muaj qhov chaw nyob sib xws, thiab nws tuaj yeem xa ncaj qha yam tsis muaj kev ntxhov siab.
Ntau tus neeg siv MU-MIMO thev naus laus zis tso cai rau ntau lub davhlau ya nyob twg los qhia cov channel ntawm lub khoos phis tawj lub sijhawm, kom ntau lub xov tooj ntawm tes / khoos phis tawj tuaj yeem siv Internet tib lub sijhawm.Ua ke nrog OFDMA thev naus laus zis, txhua channel nyob rau hauv WiFi 6 network tuaj yeem ua cov ntaub ntawv xa mus tau zoo, txhim kho ntau tus neeg siv Lub network kev paub hauv qhov chaw tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm WiFi hotspot thaj chaw, siv ntau tus neeg siv, thiab nws tsis yooj yim. kom khov, thiab lub peev xwm loj dua.
Muaj kev nyab xeeb dua
Yog tias WiFi 6 (wireless router) ntaus ntawv yuav tsum tau ntawv pov thawj los ntawm WiFi Alliance, nws yuav tsum tau txais yuav WPA 3 kev ruaj ntseg raws tu qauv, uas muaj kev nyab xeeb dua.
Thaum pib ntawm 2018, WiFi Alliance tau tshaj tawm cov tiam tshiab ntawm WiFi encryption raws tu qauv WPA 3, uas yog ib qho kev hloov kho tshiab ntawm WPA 2 raws tu qauv.Kev ruaj ntseg tau txhim kho ntxiv, thiab nws tuaj yeem tiv thaiv kev tawm tsam brute force thiab brute force cracking.
ntau zog txuag
WiFi 6 qhia txog TARget Wake Time (TWT) thev naus laus zis, uas tso cai rau kev npaj lub sijhawm sib txuas lus ntawm cov khoom siv thiab wireless routers, txo kev siv lub wireless network kav hlau txais xov thiab lub sijhawm tshawb nrhiav teeb liab, uas tuaj yeem txo qis kev siv hluav taws xob rau qee qhov thiab txhim kho cov khoom siv roj teeb. lub neej.
HUANET muab WIFI 6 ONT, yog tias koj txaus siab rau nws, pls hu rau peb.
