Koj puas xav paub seb koj tus hluas nraug puas nyiam ua si computer games? Cia kuv qhia koj ib qho tswv yim, koj tuaj yeem xyuas seb nws lub computer puas muaj kev sib txuas network cable lossis tsis muaj. Vim tias cov tub hluas muaj qhov yuav tsum tau ceev network thiab qeeb thaum ua si games, thiab feem ntau ntawm WiFi hauv tsev tam sim no ua tsis tau qhov no txawm tias qhov ceev ntawm broadband network ceev txaus, yog li cov tub hluas uas feem ntau ua si games feem ntau xaiv kev nkag mus rau broadband los xyuas kom meej tias muaj ib puag ncig network ruaj khov thiab ceev.
Qhov no kuj qhia txog cov teeb meem ntawm kev sib txuas WiFi: latency siab thiab tsis ruaj khov, uas pom tseeb dua rau ntau tus neeg siv tib lub sijhawm, tab sis qhov xwm txheej no yuav zoo dua nrog kev tuaj txog ntawm WiFi 6. Qhov no yog vim WiFi 5, uas feem ntau cov neeg siv, siv OFDM thev naus laus zis, thaum WiFi 6 siv OFDMA thev naus laus zis. Qhov sib txawv ntawm ob txoj kev tuaj yeem piav qhia los ntawm daim duab:
Ntawm txoj kev uas tsuas muaj ib lub tsheb xwb, OFDMA tuaj yeem xa ntau lub davhlau ya nyob twg tib lub sijhawm, tshem tawm cov kab thiab kev sib tsoo, txhim kho kev ua haujlwm zoo thiab txo qhov latency. OFDMA faib cov channel wireless ua ntau lub subchannels hauv qhov zaus, yog li ntau tus neeg siv tuaj yeem xa cov ntaub ntawv tib lub sijhawm hauv txhua lub sijhawm, uas txhim kho kev ua haujlwm zoo thiab txo qhov qeeb ntawm kev tos kab.
Txij li thaum nws pib tsim tawm, WIFI 6 tau nrov heev, vim tias tib neeg xav tau ntau lub network wireless hauv tsev. Muaj ntau dua 2 billion lub Wi-Fi 6 terminals tau xa tawm thaum kawg ntawm xyoo 2021, suav txog ntau dua 50% ntawm tag nrho cov Wi-Fi terminals xa tawm, thiab tus lej ntawd yuav nce mus txog 5.2 billion los ntawm xyoo 2025, raws li lub tuam txhab tshuaj ntsuam IDC.
Txawm hais tias Wi-Fi 6 tau tsom mus rau kev paub ntawm cov neeg siv hauv cov xwm txheej ceev ceev, cov ntawv thov tshiab tau tshwm sim hauv xyoo tas los no uas xav tau kev xa tawm ntau dua thiab latency, xws li cov yeeb yaj kiab ultra-high-definition xws li 4K thiab 8K cov yeeb yaj kiab, kev ua haujlwm deb, kev sib tham video online, thiab VR / AR games. Cov tuam txhab loj hauv thev naus laus zis kuj pom cov teeb meem no, thiab Wi-Fi 7, uas muaj kev ceev ceev heev, muaj peev xwm siab thiab latency qis, tab tom caij nthwv dej. Cia peb coj Qualcomm's Wi-Fi 7 ua piv txwv thiab tham txog dab tsi Wi-Fi 7 tau txhim kho.
Wi-nkaus 7: Txhua yam rau qhov qeeb qeeb
1. Bandwidth siab dua
Dua li no, mus rau ntawm txoj kev. Wi-fi 6 feem ntau txhawb nqa 2.4ghz thiab 5ghz bands, tab sis txoj kev 2.4ghz tau raug sib koom los ntawm Wi-Fi thaum ntxov thiab lwm yam thev naus laus zis wireless xws li Bluetooth, yog li nws dhau los ua neeg coob heev. Txoj kev ntawm 5GHz dav dua thiab tsawg dua li ntawm 2.4ghz, uas txhais tau tias ceev dua thiab muaj peev xwm ntau dua. Wi-fi 7 txawm txhawb nqa 6GHz band ntxiv rau ob bands no, nthuav dav qhov dav ntawm ib txoj kab los ntawm Wi-Fi 6's 160MHz mus rau 320MHz (uas tuaj yeem nqa ntau yam hauv ib lub sijhawm). Thaum ntawd, Wi-Fi 7 yuav muaj qhov siab tshaj plaws ntawm kev xa mus rau ntau dua 40Gbps, plaub npaug ntau dua li Wi-Fi 6E.
2. Kev Nkag Mus Rau Ntau Qhov Txuas
Ua ntej Wi-Fi 7, cov neeg siv tsuas yog siv tau ib txoj kev uas haum rau lawv cov kev xav tau xwb, tab sis Qualcomm's Wi-Fi 7 solution thawb cov kev txwv ntawm Wi-Fi ntxiv mus: yav tom ntej, tag nrho peb txoj kab yuav tuaj yeem ua haujlwm tib lub sijhawm, txo qhov kev sib tsoo. Tsis tas li ntawd, raws li qhov ua haujlwm multi-link, cov neeg siv tuaj yeem txuas los ntawm ntau txoj kab, siv qhov no kom tsis txhob muaj kev sib tsoo. Piv txwv li, yog tias muaj tsheb khiav ntawm ib txoj kab, lub cuab yeej tuaj yeem siv lwm txoj kab, ua rau muaj kev ncua sijhawm qis dua. Lub caij no, nyob ntawm seb muaj thaj chaw sib txawv, multi-link tuaj yeem siv ob txoj kab hauv 5GHz band lossis kev sib xyaw ua ke ntawm ob txoj kab hauv 5GHz thiab 6GHz bands.
3. Kev Sib Sau Ua Ke Channel
Raws li tau hais los saum toj no, Wi-Fi 7 bandwidth tau nce mus txog 320MHz (dav ntawm lub tsheb). Rau 5GHz band, tsis muaj 320MHz band txuas ntxiv mus, yog li tsuas yog thaj tsam 6GHz thiaj li txhawb nqa hom txuas ntxiv no. Nrog rau qhov ua haujlwm ntau-bandwidth tib lub sijhawm, ob lub zaus band tuaj yeem sib sau ua ke tib lub sijhawm los sau cov throughput ntawm ob txoj kab, uas yog, ob lub teeb liab 160MHz tuaj yeem sib koom ua ke los tsim ib txoj kab zoo 320MHz (dav txuas ntxiv). Ua li no, lub tebchaws zoo li peb li, uas tseem tsis tau muab 6GHz spectrum, kuj tseem tuaj yeem muab cov channel dav txaus kom ua tiav cov throughput siab heev hauv cov xwm txheej congested.
4. 4K QAM
Qhov kev hloov kho siab tshaj plaws ntawm Wi-Fi 6 yog 1024-QAM, thaum Wi-Fi 7 tuaj yeem ncav cuag 4K QAM. Ua li no, qhov siab tshaj plaws tuaj yeem nce ntxiv kom nce qhov kev xa tawm thiab cov ntaub ntawv muaj peev xwm, thiab qhov ceev kawg tuaj yeem ncav cuag 30Gbps, uas yog peb npaug ntawm qhov ceev ntawm 9.6Gbps WiFi 6 tam sim no.
Hauv ntej, Wi-Fi 7 yog tsim los muab kev xa cov ntaub ntawv ceev heev, muaj peev xwm siab, thiab qeeb qeeb los ntawm kev nce tus naj npawb ntawm txoj kab uas muaj, qhov dav ntawm txhua lub tsheb thauj cov ntaub ntawv, thiab qhov dav ntawm txoj kab mus ncig.
Wi-fi 7 Qhib Txoj Kev Rau High-speed Multi-connected IoT
Raws li tus sau xav, lub hauv paus ntawm Wi-Fi 7 thev naus laus zis tshiab tsis yog tsuas yog txhim kho qhov ceev ntawm ib lub cuab yeej xwb, tab sis kuj tseem yuav tsum tau them sai sai rau qhov kev sib kis ceev ceev hauv kev siv ntau tus neeg siv (ntau txoj kab nkag), uas yog qhov tseeb raws li lub sijhawm Internet of Things yav tom ntej. Tom ntej no, tus sau yuav tham txog cov xwm txheej iot zoo tshaj plaws:
1. Kev Lag Luam Hauv Is Taws Nem ntawm Yam
Ib qho ntawm cov teeb meem loj tshaj plaws ntawm cov thev naus laus zis iot hauv kev tsim khoom yog bandwidth. Cov ntaub ntawv ntau dua uas tuaj yeem sib txuas lus ib zaug, Iiot yuav ua haujlwm sai dua thiab ua haujlwm tau zoo dua. Hauv qhov xwm txheej ntawm kev soj ntsuam kev ruaj ntseg zoo hauv Industrial Internet of Things, qhov ceev ntawm network yog qhov tseem ceeb rau kev ua tiav ntawm cov ntawv thov tiag tiag. Nrog kev pab los ntawm lub network Iiot ceev ceev, cov lus ceeb toom tiag tiag tuaj yeem xa tuaj raws sijhawm rau kev teb sai dua rau cov teeb meem xws li kev ua tsis tiav ntawm lub tshuab thiab lwm yam kev cuam tshuam, txhim kho kev tsim khoom thiab kev ua haujlwm ntawm cov tuam txhab tsim khoom thiab txo cov nqi tsis tsim nyog.
2. Kev suav ntug
Nrog rau qhov kev thov ntawm tib neeg rau kev teb sai ntawm cov tshuab ntse thiab kev ruaj ntseg ntawm cov ntaub ntawv ntawm Internet of Things tau nce siab thiab siab dua, kev suav huab yuav raug tso tseg yav tom ntej. Edge computing tsuas yog hais txog kev suav ntawm sab neeg siv, uas tsis yog tsuas yog xav tau lub zog suav siab ntawm sab neeg siv, tab sis kuj tseem xav tau qhov ceev ntawm kev xa cov ntaub ntawv ntawm sab neeg siv.
3. Kev siv AR/VR uas muaj zog heev
Kev siv VR uas nkag tau yooj yim yuav tsum teb sai raws li cov kev ua tiag tiag ntawm cov neeg ua si, uas yuav tsum tau muaj kev ncua qeeb heev ntawm lub network. Yog tias koj ib txwm muab cov neeg ua si teb qeeb ib zaug xwb, ces kev nkag mus rau hauv kev ua si yog kev dag ntxias. Wi-fi 7 xav tias yuav daws qhov teeb meem no thiab ua kom kev siv AR/VR nkag tau sai dua.
4. Kev ruaj ntseg ntse
Nrog rau kev txhim kho ntawm kev ruaj ntseg ntse, daim duab xa los ntawm cov koob yees duab ntse tau dhau los ua qhov siab dua, uas txhais tau tias cov ntaub ntawv dynamic xa mus tau loj dua thiab loj dua, thiab cov kev xav tau rau bandwidth thiab network ceev kuj tau nce siab dua thiab siab dua. Ntawm LAN, WIFI 7 yog qhov kev xaiv zoo tshaj plaws.
Thaum Kawg
Wi-Fi 7 zoo, tab sis tam sim no, cov teb chaws muaj kev xav sib txawv txog seb puas yuav tso cai rau WiFi nkag mus rau hauv 6GHz (5925-7125mhz) band ua band tsis muaj ntawv tso cai. Lub teb chaws tseem tsis tau muab txoj cai meej rau 6GHz, tab sis txawm tias tsuas yog 5GHz band muaj, Wi-Fi 7 tseem tuaj yeem muab qhov siab tshaj plaws ntawm 4.3Gbps, thaum Wi-Fi 6 tsuas yog txhawb nqa qhov ceev download ntawm 3Gbps thaum 6GHz band muaj. Yog li ntawd, nws xav tias Wi-Fi 7 yuav ua lub luag haujlwm tseem ceeb hauv Lans ceev ceev yav tom ntej, pab ntau dua thiab ntau dua cov khoom siv ntse kom tsis txhob raug ntes los ntawm lub cable.
