Wi-nkaus 6E yog ib tug tshiab frontier rau Wi-Fi 6 technology.Lub "E" sawv cev rau "Ntxiv," ntxiv 6GHz band tshiab rau thawj 2.4GHz thiab 5Ghz bands.Hauv thawj peb lub hlis twg xyoo 2020, Broadcom tau tshaj tawm thawj qhov kev sim ua haujlwm ntawm Wi-Fi 6E thiab tso tawm lub ntiaj teb thawj wi-fi 6E chipset BCM4389.Thaum Lub Tsib Hlis 29, Qualcomm tshaj tawm Wi-Fi 6E nti uas txhawb nqa routers thiab xov tooj.
Wi-nkaus Fi6 hais txog 6 tiam ntawm wireless network technology, uas nta 1.4 npaug ntawm kev sib txuas hauv Is Taws Nem nrawm dua piv rau tiam 5.Thib ob, thev naus laus zis tshiab, kev siv OFDM orthogonal Frequency division multiplexing thev naus laus zis thiab MU-MIMO thev naus laus zis, ua rau Wi-Fi 6 los muab kev sib txuas hauv network ruaj khov rau cov khoom siv txawm tias nyob hauv ntau qhov kev sib txuas ntawm cov cuab yeej thiab tswj kev ua haujlwm zoo sib xws.
Wireless signals raug xa mus nyob rau hauv cov kev txwv tsis pub muaj ntawv tso cai spectrum tau teev tseg los ntawm txoj cai.Thawj peb tiam ntawm wireless technologies, WiFi 4, WiFi 5 thiab WiFi 6, siv ob lub teeb liab band, raws li qhia hauv daim duab hauv qab no.Ib qho yog 2.4ghz band, uas yog qhov yooj yim los cuam tshuam los ntawm tus tswv ntawm cov khoom siv, suav nrog cov menyuam saib xyuas thiab microwave ncu.Lwm qhov, 5GHz band, tam sim no jammed los ntawm ib txwm Wi-nkaus li thiab tes hauj lwm.
Lub tshuab txuag hluav taws xob TWT (TargetWakeTime) qhia los ntawm WiFi 6 raws tu qauv 802.11ax muaj qhov yooj yim dua, tso cai rau lub zog txuag hluav taws xob ntev dua, thiab ntau lub cuab yeej pw tsaug zog.Feem ntau hais lus, nws muaj qhov zoo hauv qab no:
1. AP sib tham nrog lub cuab yeej thiab txhais lub sijhawm tshwj xeeb rau kev nkag mus rau hauv xov xwm.
2. Txo kev sib cav thiab sib tshooj ntawm cov neeg siv khoom;
3. Ua kom lub sijhawm pw tsaug zog ntawm lub cuab yeej kom txo tau lub zog siv.
Daim ntawv thov scenario ntawm Wi-Fi 6 zoo ib yam li 5G.Nws yog tsim rau kev kub ceev, muaj peev xwm loj, thiab tsis tshua muaj latency scenarios, nrog rau cov neeg siv khoom xws li cov xov tooj ntse, ntsiav tshuaj, cov khoom siv ntse tshiab xws li cov tsev ntse, cov ntawv siv ultra-siab txhais, thiab VR / AR.Kev pab cuam xws li tej thaj chaw deb 3D kho mob;High-density scenes xws li tshav dav hlau, tsev so, chaw ua haujlwm loj, thiab lwm yam. Muaj cov xwm txheej xws li cov chaw tsim khoom ntse, cov tsev khaws khoom tsis muaj neeg, thiab lwm yam.
Tsim los rau lub ntiaj teb uas txhua yam txuas nrog, Wi-Fi 6 ua rau kom muaj peev xwm kis tau tus mob thiab nrawm los ntawm kev xav tias qhov sib npaug ntawm qhov sib txuas thiab cov nqi qis.Raws li Wi-Fi Alliance tsab ntawv ceeb toom, kev lag luam thoob ntiaj teb tus nqi ntawm WiFi yog 19.6 trillion US las hauv 2018, thiab nws tau kwv yees tias lub ntiaj teb kev lag luam tus nqi ntawm WiFi yuav ncav cuag 34.7 trillion US las los ntawm 2023.
Cov lag luam ntu ntawm WLAN kev ua lag luam tau loj hlob zoo nyob rau hauv q2 2021, loj hlob 22.4 feem pua ntawm xyoo dhau los rau $ 1.7 billion, raws li IDC lub ntiaj teb Wireless Local Area Networks (WLAN) peb lub hlis twg taug qab daim ntawv tshaj tawm.Hauv cov neeg siv khoom lag luam ntawm WLAN kev ua lag luam, cov nyiaj tau los poob 5.7% hauv lub quarter rau $ 2.3 nphom, ua rau 4.6% xyoo dhau ib xyoo nce hauv tag nrho cov nyiaj tau los hauv q2 2021.
Ntawm lawv, Wi-Fi 6 cov khoom lag luam txuas ntxiv loj hlob hauv cov neeg siv khoom lag luam, suav txog 24.5 feem pua ntawm tag nrho cov neeg siv khoom lag luam cov nyiaj tau los, nce los ntawm 20.3 feem pua hauv thawj peb lub hlis twg xyoo 2021. WiFi 5 cov ntsiab lus nkag tseem suav nrog feem ntau ntawm cov nyiaj tau los (64.1. %) thiab cov khoom xa tuaj (64.0%).
Wi-nkaus 6 twb muaj zog lawm, tab sis nrog kev sib kis ntawm cov tsev ntse, cov xov tooj ntawm cov khoom siv hauv tsev uas txuas mus rau wireless tau nce zuj zus, uas yuav ua rau muaj kev txwv ntau dhau ntawm 2.4GHz thiab 5GHz bands, ua rau nyuaj rau Wi-nkaus. Fi kom ncav cuag nws lub peev xwm.
IDC qhov kev kwv yees ntawm qhov loj ntawm Internet ntawm Tej yam kev sib txuas hauv Suav teb hauv tsib xyoos qhia tau hais tias kev sib txuas hauv xov tooj thiab WiFi tus account rau qhov feem ntau ntawm txhua hom kev sib txuas.Tus naj npawb ntawm cov xov tooj thiab WiFi sib txuas tau mus txog 2.49 billion hauv 2020, suav txog 55.1 feem pua ntawm tag nrho, thiab xav tias yuav ncav cuag 4.68 billion los ntawm 2025. Hauv kev soj ntsuam video, kev lag luam iot, lub tsev ntse thiab ntau lwm yam xwm txheej, wired thiab WiFi tseem yuav muaj. ua lub luag haujlwm tseem ceeb.Yog li ntawd, kev nce qib thiab daim ntawv thov ntawm WiFi 6E yog qhov tsim nyog heev.
Qhov tshiab 6Ghz band yog qhov tsis ua haujlwm, muab ntau qhov spectrum.Piv txwv li, txoj kev paub zoo tuaj yeem muab faib ua 4 txoj kab, 6 txoj kab, 8 txoj kab, thiab lwm yam, thiab cov spectrum zoo li "txoj kab" siv rau kev xa xov.Ntau cov kev pabcuam spectrum txhais tau tias ntau "txoj kab", thiab kev sib kis tau zoo yuav raug txhim kho raws li.
Nyob rau tib lub sijhawm, 6GHz band tau ntxiv, uas zoo li lub viaduct hla txoj kev uas twb muaj neeg coob coob, ua rau tag nrho kev thauj mus los ntawm txoj kev txhim kho ntxiv.Yog li ntawd, tom qab kev taw qhia ntawm 6GHz band, ntau yam spectrum tswj cov tswv yim ntawm Wi-Fi 6 tuaj yeem siv tau zoo dua thiab ua tiav, thiab kev sib txuas lus tau zoo dua, yog li muab kev ua tau zoo dua, ntau dua thiab qis dua latency.
Nyob rau hauv daim ntawv thov, WiFi 6E zoo daws qhov teeb meem ntawm ntau congestion nyob rau hauv 2.4ghz thiab 5GHz bands.Tom qab tag nrho, muaj ntau thiab ntau cov khoom siv wireless hauv tsev tam sim no.Nrog 6GHz, cov khoom siv hauv Is Taws Nem xav tau tuaj yeem txuas rau cov qhab no, thiab nrog 2.4GHz thiab 5GHz, qhov siab tshaj plaws ntawm WiFi tuaj yeem pom tau.
Tsis tas li ntawd xwb, tab sis WiFi 6E kuj tseem muaj kev txhawb nqa loj ntawm lub xov tooj nti, nrog tus nqi siab tshaj ntawm 3.6Gbps, ntau dua ob npaug ntawm WiFi 6 nti.Tsis tas li ntawd, WiFi 6E muaj qhov qeeb qeeb ntawm tsawg dua 3 milliseconds, uas yog ntau dua 8 npaug qis dua cov 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.
