Wi-fi 6E yog ib txoj kev tshiab rau thev naus laus zis Wi-Fi 6. Tus "E" sawv cev rau "Extended," ntxiv ib qho 6GHz band tshiab rau cov 2.4ghz thiab 5Ghz bands qub. Hauv peb lub hlis thawj zaug ntawm xyoo 2020, Broadcom tau tso tawm cov txiaj ntsig sim thawj zaug ntawm Wi-Fi 6E thiab tso tawm lub ntiaj teb thawj wi-fi 6E chipset BCM4389. Thaum Lub Tsib Hlis 29, Qualcomm tau tshaj tawm Wi-Fi 6E chip uas txhawb nqa cov routers thiab xov tooj.
Wi-fi Fi6 yog hais txog tiam 6 ntawm kev siv tshuab wireless network, uas muaj qhov ceev sib txuas hauv internet ceev dua 1.4 npaug piv rau tiam 5. Qhov thib ob, kev tsim kho tshiab ntawm thev naus laus zis, kev siv OFDM orthogonal Frequency division multiplexing technology thiab MU-MIMO technology, ua rau Wi-Fi 6 muab kev sib txuas network ruaj khov rau cov khoom siv txawm tias nyob rau hauv ntau lub cuab yeej sib txuas thiab tswj kev ua haujlwm network du.
Cov teeb liab wireless raug xa mus rau hauv qhov spectrum tsis muaj ntawv tso cai uas tau teev tseg los ntawm txoj cai. Peb tiam neeg thawj zaug ntawm cov thev naus laus zis wireless, WiFi 4, WiFi 5 thiab WiFi 6, siv ob lub teeb liab, raws li pom hauv daim duab hauv qab no. Ib qho yog 2.4ghz band, uas yooj yim rau kev cuam tshuam los ntawm ntau yam khoom siv, suav nrog cov saib menyuam yaus thiab cov qhov cub microwave. Qhov thib ob, 5GHz band, tam sim no raug cuam tshuam los ntawm cov khoom siv Wi-Fi thiab network ib txwm muaj.
Lub tshuab txuag hluav taws xob TWT (TargetWakeTime) uas tau qhia los ntawm WiFi 6 protocol 802.11ax muaj kev ywj pheej ntau dua, ua rau lub voj voog txuag hluav taws xob ntev dua, thiab teem sijhawm pw tsaug zog ntawm ntau lub cuab yeej. Feem ntau hais lus, nws muaj cov txiaj ntsig hauv qab no:
1. Tus AP sib tham nrog lub cuab yeej thiab teem sijhawm tshwj xeeb los nkag mus rau cov xov xwm.
2. Txo kev sib cav sib ceg thiab kev sib tshooj ntawm cov neeg siv khoom;
3. Ua kom lub sijhawm pw tsaug zog ntawm lub cuab yeej ntau ntxiv kom txo tau kev siv hluav taws xob.
Cov xwm txheej ntawm daim ntawv thov ntawm Wi-Fi 6 zoo ib yam li 5G. Nws yog qhov tsim nyog rau kev kub ceev, muaj peev xwm loj, thiab qis latency, suav nrog cov xwm txheej ntawm cov neeg siv khoom xws li xov tooj ntse, ntsiav tshuaj, cov davhlau ya nyob twg ntse tshiab xws li tsev ntse, cov ntawv thov ultra-high definition, thiab VR / AR. Cov xwm txheej kev pabcuam xws li kev kho mob 3D nyob deb; Cov xwm txheej siab xws li tshav dav hlau, tsev so, chaw loj, thiab lwm yam. Cov xwm txheej qib kev lag luam xws li cov chaw tsim khoom ntse, cov chaw khaws khoom tsis muaj neeg tsav, thiab lwm yam.
Tsim los rau lub ntiaj teb uas txhua yam txuas nrog, Wi-Fi 6 ua rau muaj peev xwm xa xov thiab ceev dua los ntawm kev xav tias qhov sib npaug ntawm uplink thiab downlink. Raws li daim ntawv tshaj tawm Wi-Fi Alliance, tus nqi lag luam thoob ntiaj teb ntawm WiFi yog 19.6 trillion US dollars hauv xyoo 2018, thiab kwv yees tias tus nqi lag luam thoob ntiaj teb ntawm WiFi yuav ncav cuag 34.7 trillion US dollars los ntawm xyoo 2023.
Cov lag luam ntawm WLAN kev lag luam tau loj hlob zoo hauv q2 2021, loj hlob 22.4 feem pua xyoo dhau los mus txog $ 1.7 billion, raws li IDC daim ntawv qhia txog Wireless Local Area Networks (WLAN) thoob ntiaj teb txhua peb lub hlis. Hauv cov neeg siv khoom ntawm WLAN kev lag luam, cov nyiaj tau poob qis 5.7% hauv peb lub hlis mus txog $ 2.3 billion, ua rau muaj kev nce 4.6% xyoo-dhau-xyoo hauv tag nrho cov nyiaj tau los hauv q2 2021.
Ntawm lawv, cov khoom Wi-Fi 6 txuas ntxiv loj hlob hauv kev lag luam neeg siv khoom, suav txog 24.5 feem pua ntawm tag nrho cov nyiaj tau los ntawm cov neeg siv khoom, nce ntxiv los ntawm 20.3 feem pua hauv peb lub hlis twg ntawm xyoo 2021. WiFi 5 cov chaw nkag tseem suav txog feem ntau ntawm cov nyiaj tau los (64.1%) thiab cov khoom xa tuaj (64.0%).
Wi-fi 6 twb muaj zog lawm, tab sis nrog rau kev nthuav dav ntawm cov tsev ntse, tus naj npawb ntawm cov khoom siv hauv tsev uas txuas rau wireless tau nce ntxiv ntau heev, uas yuav ua rau muaj kev sib tsoo ntau dhau hauv 2.4ghz thiab 5GHz bands, ua rau nws nyuaj rau Wi-Fi kom ncav cuag nws lub peev xwm tag nrho.
IDC qhov kev kwv yees txog qhov loj ntawm Internet of Things kev sib txuas hauv Suav teb hauv tsib xyoos qhia tau hais tias kev sib txuas wired thiab WiFi suav rau qhov feem pua ntau tshaj plaws ntawm txhua hom kev sib txuas. Tus lej ntawm kev sib txuas wired thiab WiFi tau txog 2.49 billion hauv xyoo 2020, suav txog 55.1 feem pua ntawm tag nrho, thiab xav tias yuav ncav cuag 4.68 billion los ntawm xyoo 2025. Hauv kev saib xyuas video, kev lag luam iot, lub tsev ntse thiab ntau lwm yam xwm txheej, wired thiab WiFi tseem yuav ua lub luag haujlwm tseem ceeb. Yog li ntawd, kev txhawb nqa thiab kev siv WiFi 6E yog qhov tsim nyog heev.
Qhov 6Ghz band tshiab no tsis muaj dab tsi siv, muab ntau lub spectrum. Piv txwv li, txoj kev uas paub zoo no muaj peev xwm muab faib ua 4 txoj kab, 6 txoj kab, 8 txoj kab, thiab lwm yam, thiab lub spectrum zoo li "txoj kab" siv rau kev xa cov teeb liab. Ntau cov peev txheej spectrum txhais tau tias ntau "txoj kab", thiab kev ua haujlwm ntawm kev xa xov yuav raug txhim kho raws li ntawd.
Tib lub sijhawm ntawd, 6GHz band tau ntxiv rau, uas zoo li lub viaduct hla txoj kev uas twb muaj neeg coob lawm, ua rau kev thauj mus los ntawm txoj kev zoo dua ntxiv. Yog li ntawd, tom qab kev qhia txog 6GHz band, ntau yam kev tswj hwm spectrum ntawm Wi-Fi 6 tuaj yeem siv tau zoo dua thiab tiav, thiab kev sib txuas lus zoo dua, yog li muab kev ua tau zoo dua, kev xa khoom ntau dua thiab latency qis dua.
Ntawm theem daim ntawv thov, WiFi 6E daws tau qhov teeb meem ntawm kev sib tsoo ntau dhau hauv 2.4ghz thiab 5GHz bands. Tom qab tag nrho, muaj ntau thiab ntau dua cov khoom siv wireless hauv tsev tam sim no. Nrog 6GHz, cov khoom siv uas xav tau internet tuaj yeem txuas rau qhov band no, thiab nrog 2.4ghz thiab 5GHz, qhov siab tshaj plaws ntawm WiFi tuaj yeem ua tiav.
Tsis yog li ntawd xwb, tab sis WiFi 6E kuj muaj kev txhawb nqa loj rau lub xov tooj lub chip, nrog rau qhov siab tshaj plaws ntawm 3.6Gbps, ntau dua ob npaug ntawm WiFi 6 chip. Tsis tas li ntawd, WiFi 6E muaj qhov qeeb qis dua tsawg dua 3 milliseconds, uas yog ntau dua 8 npaug qis dua tiam dhau los hauv qhov chaw ntom ntom. Nws tuaj yeem muab kev paub zoo dua hauv kev ua si, HIGH-DEFINITION video, suab thiab lwm yam.
