Wi-Fi 7 (IEEE 802.11be) yog lub xya tiam ntawm WiFi wireless network, nrog rau kev ceev txog li 30Gbps, uas yog peb npaug ntawm qhov siab tshaj plaws ntawm WiFi 6 (9.6Gbps). Wi-Fi 7 yog lub cim thib xya ntawm 802.11 tus qauv txij li xyoo 1997. Nws muab cov txiaj ntsig zoo ntawm WiFi 6/6E thiab nthuav ntau cov qauv uas twb muaj lawm mus rau qib tshiab, xws li 320 MHz bandwidth loj thiab 4K-QAM. Tsis tas li ntawd xwb, nws tseem qhia txog kev hloov pauv xws li kev sib txuas ntawm ntau pawg, ntau qhov chaw siv (MRU) thiab preamble deletion technology. Raws li WiFi dhau los ua ib feem tseem ceeb ntawm kev ua haujlwm niaj hnub thiab tsev neeg lub neej, WiFi 7 yuav hloov kho koj qhov kev paub WiFi nrog lub peev xwm zoo los txuas rau yav tom ntej.

Wi-Fi 7 yog 4.8 npaug sai dua Wi-Fi 6, nrog lub peev xwm 5 npaug siab dua thiab ultra-low latency. Nws cov yam ntxwv muaj xws li:
320 MHz bandwidth
WiFi 6E nce bandwidth ntawm 6 GHz band mus rau 160 MHz, thaum WiFi 7 thawb lub bandwidth mus rau ultra-wide 320 MHz, ob npaug ntawm cov ntaub ntawv hloov chaw. Koj tuaj yeem xav txog lub network raws li txoj kev loj virtual, nrog ob npaug bandwidth zoo li txoj kab uas dav dua ob zaug. Tam sim no, cov tsheb loj uas nqa cov ntaub ntawv ntau dua tuaj yeem taug kev ntawm txoj kev loj.
WiFi 7 lub zog yuav tsum tau siv nrog WiFi routers thiab cov neeg siv khoom siv uas txhawb nqa WiFi 7 kev khiav haujlwm los txhawb cov haujlwm sib xws.
4K QAM
Vim qhov kev taw qhia ntawm 4K-QAM hauv WIFI7, WiFi 7 muaj 20% nce hauv cov ntaub ntawv xa mus rau tus nqi piv rau WiFi 6/6E, vim tias QAM ntau dua txhais tau tias cov ntaub ntawv tuaj yeem compressed ntau dua rau hauv cov teeb liab kis tau tus mob. Txuas ntxiv txoj kev loj piv txwv, QAM siab dua txhais tau tias ntau cov khoom tuaj yeem thauj khoom ntawm lub tsheb. Hauv lwm lo lus, tam sim no koj tuaj yeem rub tawm thiab rub tawm cov ntaub ntawv ntau dua hauv tib lub sijhawm ua ntej.
MLO (Multi-Link Operation)
Ua ntej WiFi 7, kev sib kis tau raug txwv rau ib zaus band, xws li 2.4 GHz lossis 5 GHz. Multi-Link Operation Technology (MLO) tso cai rau cov cuab yeej txuas mus rau ntau lub zaus bands ib txhij, ua tiav kev nrawm dua los ntawm hom kev sib sau ua ke (STR hom) thiab seamless switching hom (eMLRS hom) los muab kev sib txuas ntawm WiFi ntau dua kev sib txuas ntawm ntau lub zog siv ib txhij.
Multiple Resource Unit (MRU) thiab Preamble Removal Technology
Hauv WiFi 6, yog tias ib qho channel ntsib teeb meem cuam tshuam, cov peev txheej spectrum yuav raug pov tseg. WiFi 7 cov khoom siv tau nruab nrog Multi-Resource Unit (Multi-RU) thiab Puncturing thev naus laus zis, uas tuaj yeem ua kom tag nrho cov kev siv tsis siv lossis cuam tshuam, siv tau zoo siv WiFi bandwidth, ua kom cov ntaub ntawv xa mus sai, thiab ua kom muaj kev sib txuas ntau dua.
16 × 16 MU-MIMO
MU-MIMO (Multi-user MIMO) txhawb ntau tus neeg siv xa thiab tau txais cov ntaub ntawv tib lub sijhawm. Nrog 16 × 16 MU-MIMO, WiFi 7 muab ob npaug rau tus naj npawb ntawm cov kwj deg piv rau WiFi 6, yog li ua kom muaj peev xwm hauv network. Tam sim no, ntau cov khoom siv WiFi uas xav tau ntau lub peev xwm hauv lub network tuaj yeem ua haujlwm zoo tib lub sijhawm.
Nws yog ib qho tsim nyog sau cia tias 16 × 16 MU-MIMO yog tus qauv kev tshaj lij ntawm WiFi 7, tab sis nws tsis yog qhov yuav tsum tau ua ntawm txhua yam khoom siv WiFi 7.
