Koj puas xav paub seb koj tus hluas nraug nyiam ua si computer? Cia kuv qhia koj cov lus qhia, koj tuaj yeem tshawb xyuas nws lub khoos phis tawm yog network cable txuas lossis tsis. Vim tias cov tub hluas muaj lub siab muaj cov kev ua si nrawm thiab qeeb thaum cov tub ua si feem ntau ua si rau cov neeg siv hluav taws xob ua si kom paub meej tias yog ib puag ncig ruaj khov thiab nrawm.
Qhov no tseem qhia txog cov teeb meem ntawm WiFi kev txuas: muaj qhov tsis txaus ntseeg, siv cov thev naus laus zis ntau, siv WiFi 6 siv Andma Technology. Qhov sib txawv ntawm ob cov tswv yim tuaj yeem tso tau yooj yim:
Ntawm ib txoj kev uas tuaj yeem haum rau ib lub tsheb, Formma tuaj yeem hloov pauv tau hloov ntau yam hauv parallel, tshem tawm cov qoj ib puag ncig thiab kev txhim kho, txhim kho kev ua haujlwm thiab txo cov latency. Wordma faib cov wireless channel rau hauv ntau subchanels nyob rau hauv paridel hauv paridel nyob rau hauv txhua lub sij hawm xa mus rau txhua lub sijhawm, uas txhim kho qhov kev ua tau zoo thiab txo qhov kev ncua sijhawm ntawm cov qoj ib ce.
WiFi 6 tau raug ntaus txij thaum nws pib, raws li tib neeg xav tau ntau thiab ntau dua cov khoom siv hauv tsev. Ntau tshaj 2 billion Wi-Fi 6 Terminals tau xa mus rau qhov kawg ntawm 2021, suav rau ntau tshaj 50% yuav loj tuaj rau 7,2 lab los ntawm 2025, raws li cov kws ntsuam xyuas Idc.
Txawm hais tias Wi-Fi 6 tau tsom mus rau cov neeg siv kev paub hauv cov yeeb yaj kiab hights, xws li cov yeeb yaj kiab tsis ntev los no, kev ua haujlwm chaw taws teeb, thiab VR / AR Games. Tech Giants pom cov teeb meem no ib yam nkaus thiab, thiab Wi-Fi 7, uas muaj kev nrawm, muaj peev xwm qis, yog caij nthwv dej. Cia peb coj Lees Liaj ua li Wi-Fi 7 ua piv txwv thiab tham txog dab tsi Wi-nkaus 7 tau txhim kho.
Wi-Fi 7: Txhua yam rau latency latency latency
1. Ntau dua bandwidth
Dua, coj txoj kev. Wi-nkaus 6 feem ntau txhawb nqa lub 2.4GHz thiab 500z txoj kev tau qhia los ntawm Wi-Fi thiab lwm yam wireless thev naus laus zis xws li Bluetooth, yog li nws yuav ua tiav heev. Txoj kev ntawm 5GHz yog dav thiab tsis muaj neeg coob tshaj li ntawm 2.4GHz, uas txhais rau hauv kev nrawm dua thiab muaj peev xwm ntau dua. WI-FI 7 txawm txhawb nqa 6GHz Band rau saum ob pawg, nthuav dav dav ntawm ib qho channel los ntawm Wi-Fi 6's 160MHz mus rau 320mHz (uas tuaj yeem nqa ntau yam ntxiv ntawm ib lub sijhawm). Nyob rau ntawm qhov ntawd, Wi-Fi 7 yuav muaj lub ncov ntxig tus nqi ntawm ntau dua 40Gbps, plaub zaug siab dua Wi-Fi 6E 6E.
2. Ntau qhov txuas nkag
Ua ntej WI-FI 7, cov neeg siv tsuas siv tau ib txoj kev uas zoo tshaj plaws lawv cov kev xav tau, tab sis kev daws teeb meem, tag nrho peb pawg yuav tuaj yeem ua haujlwm ib txhij, txo congesting. Tsis tas li ntawd, raws li kev sib txuas ntau qhov sib txuas, cov neeg siv tuaj yeem txuas los ntawm ntau cov channel, siv kom zoo dua qhov no kom tsis txhob congestion. Piv txwv li, yog tias muaj tsheb khiav ntawm ib qho ntawm cov channel, cov cuab yeej tuaj yeem siv tau rau lwm cov channel, uas ua rau muaj qis dua. Lub caij no, nyob ntawm cov cheeb tsam muaj ntau cov cheeb tsam sib txawv, ntau qhov txuas tuaj yeem siv ob channel nyob rau hauv 5GHz Band lossis kev sib xyaw ntawm ob txoj kab hauv 5GHz bands.
3. Kev sib sau ua ke
Raws li tau hais los saum no, Wi-Fi 7 bandwidth tau nce ntxiv rau 320mHz (tsheb dav). Rau 5GHz Band, tsis muaj ib qho kev txuas ntxiv mus ntxiv 320mHz, yog li tsuas yog 6 mailz cheeb tsam tuaj yeem txhawb nqa hom nruam no txuas ntxiv. Nrog lub siab-bandwidth fin exhip muaj nuj nqi, ob zaus bands tuaj yeem sib sau ua ke ntawm ob lub channel, uas yog, ob lub cim qhia tau ua ke los ua ib qho 320mHz ua ke channel (ncua dav). Nyob rau hauv txoj kev no, ib lub teb chaws zoo li peb tau, uas tseem tsis tau faib rau 6GHz Spectrum, tseem tuaj yeem muab ib qho dav txaus thev naus laus zis ntau heev.
4. 4K Qam
Qhov kev txiav txim siab tshaj plaws ntawm Wi-Fi 6 yog 1024-Qam, thaum Wi-Fi 7 tuaj yeem ncav cuag 4K Qam. Nyob rau hauv txoj kev no, tus nqi siab tshaj plaws tau nce ntxiv kom dhau los ntawm kev tawm mus los ntawm 30gbps, thiab zaum kawg yog peb zaug ceev ntawm tam sim no 9.6gbps WiFi 6.
Hauv ntej, Wi-Fi 7 yog tsim los muab cov ntaub ntawv kub siab heev, qhov dav ntawm cov kab kev kis tau los ntawm kev thauj cov ntaub ntawv, thiab qhov dav ntawm txoj kab kev mus ncig.
Wi-Fi 7 Clears txoj kev rau kev ceev ceev ntau-txuas iot
Nyob rau hauv tus sau lub tswv yim, cov tub ntxhais ntawm New-Fi-Fi-Fi-Fi-Fi-Fi-Fane concurrent qhov kev sib tw ua rau cov neeg siv ntau (ntau txoj kab kev nkag mus rau hauv txoj kab hauv internet ntawm tej yam era. Tom ntej no, tus sau yuav tham txog cov txiaj ntsig zoo tshaj plaws iot scenarios:
1. Industrial Internet ntawm yam
Ib qho ntawm qhov loj tshaj plaws ntawm lub raj mis ntawm iot technology hauv kev tsim khoom yog bandwidth. Cov ntaub ntawv ntau uas tuaj yeem sib tham ib zaug, kev nrawm dua thiab ua tau cov Iiot yuav ua tau. Nyob rau hauv cov ntaub ntawv ntawm kev ntsuas zoo saib xyuas kev soj ntsuam hauv Internet ntawm yam, kev ceev nrawm yog qhov tseem ceeb ntawm kev ua tiav ntawm lub sijhawm. Nrog kev pab los ntawm kev kub ceev iiot network tuaj yeem xa hauv lub tshuab tsim kev lag luam thiab kev ua tau zoo ntawm kev tsim khoom lag luam thiab txo qis cov nqi tsis tsim nyog.
2. Ntug computing
Nrog tib neeg qhov kev thov rau cov lus teb ceev ceev ntawm cov twj ntse thiab cov ntaub ntawv kev ruaj ntseg ntawm Is Taws Nem ntawm tej yam tau txais siab dua thiab huab xam tau yuav marginalized nyob rau yav tom ntej. Ntug MacTing tsuas yog hais txog qhov tsuas yog hais txog suav rau ntawm tus neeg siv sab, uas yuav tsum tsis tsuas yog siv lub zog siab ntawm tus neeg siv khoom siv ceev nrawm ntawm tus neeg siv sab.
3. Cov neeg vwm AR / VR
Cov ntsiab lus VR yuav tsum tau ua kom haum rau cov lus teb nrawm raws li cov kev ua ntawm cov players, uas yuav tsum tau qeeb ntawm lub network. Yog tias koj ib txwm muab cov players ib-nrawm, ces immersion yog ib sham. WI-FI 7 yuav tsum tau daws qhov teeb meem no thiab nrawm rau txoj kev saws me nyuam ar / vr.
4. Txawj Ntse
Nrog rau kev txhim kho kev ruaj ntseg, daim duab kis los ntawm cov koob yees duab ntse, uas txhais tau tias cov kev xav tau loj dua, thiab cov kev xav tau rau kev ua haujlwm loj dua, thiab cov kev xav tau rau kev nrawm dua, thiab cov kev xav tau rau kev nrawm dua, thiab cov kev xav tau rau kev nrawm dua, thiab kev ceev nrawm kuj tau nce siab dua thiab siab dua. Ntawm LAN, WiFi 7 yog zaum qhov kev xaiv zoo tshaj plaws.
Thaum kawg
Wi-Fi 7 yog qhov zoo, tab sis tam sim no, lub teb chaws qhia cov cwj pwm sib txawv ntawm seb puas tso cai WiFi nkag mus rau hauv 6GHz (5925MHz) band raws li tsis muaj band. Lub teb chaws tseem tsis tau muab txoj cai ntshiab ntawm 6GHz, tab sis txawm hais tias tsuas yog tus nqi sib kis tau ntau tshaj ntawm 3Gbps thaum muaj 6GHz Band yog muaj. Yog li, nws yuav tsum tau hais tias Wi-Fi 7 yuav ua ib qho tseem ceeb tshaj plaws hauv cov tsheb khiav hauv lub neej yav tom ntej, pab ntau dua thiab ntau cov khoom siv ntse tsis txhob raug ntes los ntawm cable.
