WiFi 7, kuj technically hu ua IEEE 802.11 ib, cim kev hloov pauv hauv kev sib txuas wireless uas cog lus tias yuav hloov pauv txoj hauv kev uas peb siv Is Taws Nem hauv peb lub neej txhua hnub. Cov txheej txheem tshiab no tsis tsuas yog nthuav tawm kev vam meej tseem ceeb nyob rau hauv ceev, stability thiab efficiency, tab sis kuj tsim lub hauv paus rau yav tom ntej technologies innovation xws li virtual kev muaj tiag, la augmented kev muaj tiag thiab cov Internet ntawm yam khoom (IoT).
Txij li thaum nws tshaj tawm hauv lub Ib Hlis 2024, WiFi 7 tau dhau los ua tus nruab nrab ntawm cov saib xyuas ntawm cov kws tshaj lij technology thiab cov neeg siv khoom. Nws cov yam ntxwv tau cog lus tias yuav dhau mus dhau tiam dhau los, dhau los ua qhov kev xaiv nyiam rau tsev, tuam txhab uas muag y lom ze. Hauv qab no, peb tawg hauv kev nthuav dav dab tsi WiFi 7 yog dab tsi thiab dab tsi ua rau nws tshwj xeeb.
WiFi 7 yog dab tsi?
WiFi 7 yog lub xya tiam ntawm kev sib txuas wireless, tsim los muab kev ua haujlwm siab bandwidth, ceev thiab kev cia siab. Raws li nws lub npe hu ua IEEE 802.11be, tus qauv no txhawb nqa lub peev xwm uas twb muaj lawm ntawm WiFi 6 thiab 6E nrog kev txhim kho xws li channel dav mus txog 320 MHz thiab kev koom ua ke ntawm cov thev naus laus zis tshiab xws li Multi-Link Operation (MLO) y 4096-QAM.
Nws ua haujlwm hauv peb qhov sib txawv zaus (2,4 GHz, 5 GHz y 6 GHz) kom muaj kev sib txuas ruaj khov thiab muaj kev cuam tshuam tsawg dua. Tsis tas li ntawd, nws yog tsim los ua kom rov qab ua tau raws li cov qauv yav dhau los, tso cai rau ntau yam khoom siv los siv lawv cov tes hauj lwm, txawm tias lawv tsis siv tag nrho lawv cov peev txheej.
Cov yam ntxwv tseem ceeb ntawm WiFi 7
WiFi 7 tsis yog tsuas yog ua raws li kev txhim kho cov kev paub dhau los ntawm nws cov thawj coj, tab sis kuj suav nrog tshiab yees thiab nta uas ua rau nws sawv. Cov no yog cov yam ntxwv tseem ceeb uas txhais WiFi 7:
- Bandwidth mus txog 320 MHz: WiFi 7 raws yog ob zaug dav dua piv rau WiFi 6, ua kom muaj kev nrawm dua thiab tsis muaj kev sib txuas hauv network hauv qhov chaw ntom ntom.
- 4096-QAM Modulation: Qhov no txhais tau hais tias ntau cov ntaub ntawv tuaj yeem thauj mus rau tib lub sijhawm, nce qhov kev ua haujlwm los ntawm 20% piv rau WiFi 6.
- Multi-Link Operation (MLO): Tso cai rau siv ntau zaus bands ib txhij los txhim kho kev ceev, txo latency thiab xyuas kom muaj kev sib txuas ruaj khov dua.
- Txhim kho kev txhawb nqa rau IoT thiab cov ntawv thov siab heev: WiFi 7 yog npaj los ua lub hauv paus rau cov thev naus laus zis tshiab xws li kev muaj tiag virtual, kev muaj tiag tiag thiab lub tsev ntse.
Qhov sib txawv tseem ceeb ntawm WiFi 6 thiab WiFi 7
Kev sib piv ntawm WiFi 6/6E thiab WiFi 7 qhia kev vam meej tseem ceeb nyob rau hauv txhua txoj kev. Ntawm no peb nthuav qhia qhov sib txawv tseem ceeb tshaj plaws:
| WiFi 6 | WiFi 6 E | WiFi 7 | |
|---|---|---|---|
| IEEE Standard | 802.11ax | 802.11ax | 802.11 ib |
| Qhov siab tshaj plaws | 9,6 Gbps | 9,6 Gbps | 46 Gbps |
| Bands siv | 2,4 GHz, 5 GHz | 6 GHz | 2,4 GHz, 5 GHz, 6 GHz |
| Channel loj | Mus txog 160 MHz | Mus txog 160 MHz | Mus txog 320 MHz |
| Tes taws | 1024-QAM | 1024-QAM | 4096-QAM |
WiFi 7 yog dab tsi rau hauv lub neej txhua hnub?
Tus qauv WiFi 7 yuav tsis tsuas yog muaj txiaj ntsig zoo rau cov neeg siv hauv tsev tab tom nrhiav kom nrawm dua, tab sis kuj tuam txhab uas muag e industries. Qhov no suav nrog cov ntawv thov xws li:
- Tshaj tawm hauv 4K thiab 8K: Tso cai rau kev sib kis ntawm ultra-siab txhais cov ntsiab lus multimedia yam tsis muaj kev cuam tshuam.
- Huab kev ua si: Txo latency, ib qho tseem ceeb rau kev ua si hauv online thiab streaming gaming.
- Muaj automation: Txhim kho kev sib txuas lus ntawm cov tshuab thiab IoT khoom siv.
- Augmented thiab virtual kev muaj tiag: Qhib cov muaj peev xwm tshiab rau cov kev paub dhau los ua tsaug rau nws qhov qis latency thiab siab ruaj khov.
WiFi 7 muaj kev sib txuas ceev dua, muaj txiaj ntsig zoo thiab txhim khu kev qha wireless txuas ntxiv uas cog lus tias yuav txhawb nqa peb lub tsev thiab kev lag luam nrog kev siv thev naus laus zis ntau dua thiab muaj txiaj ntsig.
- WiFi 7 yog tus qauv IEEE 802.11be, revolutionizing wireless txuas.
- Nrog bandwidth mus txog 320 MHz thiab 4096-QAM, nws deb tshaj WiFi 6.
- Nws qhia txog kev nce qib xws li Multi-Txuas Kev Ua Haujlwm thiab kev txhawb nqa rau 2,4 GHz, 5 GHz thiab 6 GHz.
Kuv yog ib tus neeg nyiam siv thev naus laus zis uas tau hloov nws txoj kev nyiam "geek" rau hauv txoj haujlwm. Kuv tau siv ntau tshaj 10 xyoo ntawm kuv lub neej siv cov cuab yeej siv thev naus laus zis thiab tinkering nrog txhua yam kev pab cuam tawm ntawm kev xav paub dawb huv. Tam sim no kuv tau tshwj xeeb hauv computer technology thiab video games. Qhov no yog vim ntau tshaj 5 xyoo kuv tau sau rau ntau lub vev xaib ntawm kev siv tshuab thiab kev ua si video, tsim cov ntawv uas nrhiav kom muab cov ntaub ntawv koj xav tau hauv hom lus uas txhua tus neeg nkag siab.
Yog tias koj muaj lus nug, kuv qhov kev paub yog los ntawm txhua yam ntsig txog Windows operating system nrog rau Android rau cov xov tooj ntawm tes. Thiab kuv txoj kev cog lus yog rau koj, Kuv ib txwm kam siv ob peb feeb thiab pab koj daws cov lus nug uas koj muaj nyob hauv lub ntiaj teb no hauv internet.
