WIFI 5, lubIEEE 802.11 ib, yog lub thib tsib tiam wireless LAN technology. Nws tau npaj rau xyoo 2013 thiab tau siv dav hauv xyoo tom ntej. WIFI6, tseem hu uaIEEE 802.11 ax(tseem hu ua Efficient WLAN), yog thib rau-tiam wireless LAN tus qauv tsim los ntawm WIFI Alliance hauv 2019. Piv nrog WIFI5, WIFI6 tau dhau los ua ntau yam kev tsim kho tshiab thiab hloov kho dua tshiab.
2. Kev txhim kho kev ua haujlwm
2.1 Cov ntaub ntawv xa tawm siab tshaj plaws: WIFI6 siv cov thev naus laus zis thev naus laus zis ntau dua (xws li 1024-QAM) thiab cov kab dav dav (txog 160MHz), ua rau nws qhov siab tshaj plaws theoretical kis tus nqi ntau dua WIFI5, mus txog 9.6Gbps saum toj no.
2.2 Tsawg latency: WIFI6 txo qis network latency los ntawm kev qhia cov thev naus laus zis xws li TWT (Target Wake Time) thiab OFDMA (Orthogonal Frequency Division Multiple Access), ua rau nws tsim nyog rau kev sib txuas lus hauv lub sijhawm.
3.3 Kev ua tau zoo sib xws: WIFI6 txhawb nqa ntau yam khoom siv nkag mus thiab sib txuas lus tib lub sijhawm. Los ntawm MU-MIMO (Multi-User Multiple Input Multiple Output) thev naus laus zis, cov ntaub ntawv tuaj yeem xa mus rau ntau yam khoom siv tib lub sijhawm, txhim kho tag nrho cov kev xa tawm ntawm lub network. .
3. Cov cuab yeej siv tau
WIFI6 cov khoom siv ua haujlwm zoo hauv kev rov qab sib raug zoo thiab tuaj yeem txhawb WIFI5 thiab cov khoom siv dhau los. Txawm li cas los xij, nws yuav tsum raug sau tseg tias WIFI5 cov khoom siv tsis tuaj yeem txaus siab rau kev txhim kho kev ua haujlwm thiab cov yam ntxwv tshiab coj los ntawm WIFI6.
4. Txhim khu kev ruaj ntseg
WIFI6 tau txhim kho kev ruaj ntseg, qhia txog WPA3 encryption raws tu qauv, thiab muab kev tiv thaiv tus password kom muaj zog thiab cov txheej txheem kev lees paub. Tsis tas li ntawd, WIFI6 tseem txhawb nqa kev tswj hwm tus lej zais, ntxiv txhim kho kev ruaj ntseg network.
5. Cov yam ntxwv ntse
WIFI6 qhia txog cov yam ntxwv ntse dua, xws li BSS Coloring (Basic Service Set Coloring) thev naus laus zis, uas tuaj yeem txo qhov cuam tshuam ntawm cov teeb liab wireless thiab txhim kho kev ruaj ntseg network. Nyob rau tib lub sijhawm, WIFI6 tseem txhawb nqa cov tswv yim tswj hwm lub zog ntse dua, xws li Target Wake Time (TWT), uas tuaj yeem txo lub zog siv ntawm lub cuab yeej.
6. Kev siv hluav taws xob zoo
WIFI6 kuj tau txhim kho hauv kev siv hluav taws xob kom zoo. Los ntawm kev qhia txog kev hloov pauv tau zoo dua thiab cov thev naus laus zis thev naus laus zis (xws li 1024-QAM) thiab cov tswv yim tswj hwm lub zog zoo dua (xws li TWT), WIFI6 cov cuab yeej tuaj yeem tswj hwm kev siv hluav taws xob zoo dua thiab txuas ntxiv lub roj teeb lub neej ntawm lub cuab yeej thaum tswj kev ua haujlwm siab.
Cov ntsiab lus: Piv nrog WIFI5, WIFI6 muaj kev txhim kho tseem ceeb hauv ntau yam, suav nrog cov ntaub ntawv xa mus ntau dua, qis dua latency, kev ua tau zoo dua qub, kev ruaj ntseg zoo dua, cov yam ntxwv ntse dua thiab ntau dua kev ua kom zoo zog zoo. Cov kev txhim kho no ua rau WIFI6 haum rau niaj hnub wireless LAN ib puag ncig, tshwj xeeb tshaj yog nyob rau hauv high-density thiab high-concurrency application scenarios.
