Txij li thaum muaj WiFi los, cov thev naus laus zis tau hloov pauv tas li thiab hloov kho dua tshiab, thiab nws tau tso tawm mus rau WiFi 7 version.
WiFi tau nthuav dav nws txoj kev xa tawm thiab daim ntawv thov los ntawm cov khoos phis tawj thiab tes hauj lwm mus rau cov xov tooj ntawm tes, cov neeg siv khoom thiab cov khoom siv cuam tshuam nrog iot. Kev lag luam WiFi tau tsim tus qauv WiFi 6 los npog cov nodes iot uas siv hluav taws xob tsawg thiab cov ntawv thov broadband, WiFi 6E thiab WiFi 7 ntxiv 6GHz spectrum tshiab los pab rau cov ntawv thov bandwidth siab dua xws li 8K video thiab XR zaub, 6GHz spectrum ntxiv kuj xav tias yuav ua rau muaj kev txhim kho Iiot schemes txhim khu kev qha los ntawm kev txhim kho kev cuam tshuam thiab latency.
Tsab xov xwm no yuav tham txog kev lag luam WiFi thiab cov ntawv thov, nrog rau kev tsom mus rau WiFi 6E thiab WiFi 7.
Kev Lag Luam WiFi thiab Cov Ntawv Thov
Tom qab kev lag luam loj hlob zoo hauv xyoo 2021, kev lag luam WiFi xav tias yuav loj hlob 4.1% kom ncav cuag kwv yees li 4.5 billion kev sib txuas los ntawm xyoo 2022. Peb kwv yees tias kev loj hlob sai los ntawm xyoo 2023-2027, ncav cuag kwv yees li 5.7 billion los ntawm xyoo 2027. Lub tsev ntse, tsheb, thiab cov ntawv thov iot embedded yuav txhawb nqa kev loj hlob ntawm kev xa khoom siv WiFi.
Lub lag luam WiFi 6 tau pib xyoo 2019 thiab loj hlob sai heev xyoo 2020 thiab 2022. Xyoo 2022, WiFi 6 yuav suav txog li 24% ntawm tag nrho lub lag luam WiFi. Txog xyoo 2027, WiFi 6 thiab WiFi 7 ua ke yuav suav txog li ob feem peb ntawm lub lag luam WiFi. Tsis tas li ntawd, 6GHz WiFi 6E thiab WiFi 7 yuav loj hlob los ntawm 4.1% xyoo 2022 mus rau 18.8% xyoo 2027.
Xyoo 2021, WiFi 6E tau nrov heev hauv Tebchaws Meskas, tom qab ntawd xyoo 2022, thiab xyoo 2023, WiFi 7 yuav pib xa khoom mus rau Tebchaws Europe. Cov khoom siv WiFi 7 yuav pib xa khoom mus rau Tebchaws Meskas thiab yuav tshaj WiFi 6E xa khoom mus rau Tebchaws Meskas xyoo 2025.
6GHz WiFi muaj qhov zoo heev hauv kev siv broadband, kev ua si thiab kev tshaj tawm video. Nws tseem yuav yog qhov tseem ceeb rau kev siv hauv cov kev daws teeb meem iot tshwj xeeb uas xav tau kev ntseeg siab thiab kev sib txuas lus qis, xws li kev siv tshuab neeg hlau hauv Hoobkas thiab AGV. 6GHz WiFi kuj txhim kho qhov tseeb ntawm WiFi qhov chaw, yog li WiFi qhov chaw tuaj yeem ua tiav qhov chaw ua haujlwm raug dua ntawm qhov deb.
Cov Teeb Meem Hauv Kev Lag Luam WiFi
Muaj ob qho teeb meem loj hauv kev xa tawm 6GHz WiFi kev ua lag luam, qhov muaj spectrum thiab cov nqi ntxiv. Txoj cai faib spectrum 6GHz txawv ntawm lub tebchaws / cheeb tsam. Raws li txoj cai tam sim no, Tuam Tshoj thiab Lavxias yuav tsis faib 6GHz spectrum rau WiFi. Tuam Tshoj tam sim no npaj yuav siv 6GHz rau 5G, yog li Tuam Tshoj, lub khw WiFi loj tshaj plaws, yuav tsis muaj qee qhov zoo hauv kev ua lag luam WiFi 7 yav tom ntej.
Lwm qhov kev sib tw nrog 6GHz WiFi yog tus nqi ntxiv ntawm RF pem hauv ntej (broadband PA, switches thiab filters). Lub WiFi 7 chip module tshiab yuav ntxiv lwm tus nqi rau digital baseband/MAC segment los txhim kho cov ntaub ntawv throughput. Yog li ntawd, 6GHz WiFi yuav raug siv feem ntau hauv cov tebchaws tsim thiab cov khoom siv ntse siab.
Cov neeg muag khoom WiFi tau pib xa cov 2.4GHz ib-band WiFi 6 chip modules hauv xyoo 2021, hloov WiFi 4 ib txwm muaj uas siv dav hauv cov khoom siv iot. Cov yam ntxwv tshiab xws li TWT (lub sijhawm sawv ntxov lub hom phiaj) thiab BSS xim ua rau muaj kev ua haujlwm zoo ntawm cov khoom siv iot los ntawm kev ntxiv kev ua haujlwm fais fab qis dua thiab kev siv spectrum zoo dua. Los ntawm xyoo 2027, 2.4GHz ib-band WiFi 6 yuav suav txog 13% ntawm kev ua lag luam.
Rau cov ntawv thov, WiFi access points/routers/broadband gateways, high-end smartphones thiab PCS yog thawj zaug siv WiFi 6 hauv xyoo 2019, thiab cov no tseem yog cov ntawv thov tseem ceeb ntawm WiFi 6 txog niaj hnub no. Xyoo 2022, smartphones, PCS, thiab WiFi network devices yuav suav txog 84% ntawm WiFi 6/6E xa khoom. Thaum xyoo 2021-22, ntau daim ntawv thov WiFi tau hloov mus siv WiFi 6. Cov khoom siv hauv tsev ntse xws li smart TVS thiab smart speakers tau pib siv WiFi 6 hauv xyoo 2021; Cov ntawv thov iot hauv tsev thiab kev lag luam, tsheb kuj yuav pib siv WiFi 6 hauv xyoo 2022.
WiFi tes hauj lwm, cov xov tooj ntse siab heev thiab PCS yog cov ntawv thov tseem ceeb ntawm WiFi 6E / WiFi 7. Tsis tas li ntawd, 8K TVS thiab VR headsets kuj tseem yuav yog cov ntawv thov tseem ceeb ntawm 6GHz WiFi. Los ntawm xyoo 2025, 6GHz WiFi 6E yuav raug siv rau hauv kev tshaj tawm tsheb thiab kev lag luam automation.
Ib txoj kab WiFi 6 ib leeg yuav siv rau hauv cov ntawv thov WiFi ceev qis xws li cov khoom siv hauv tsev, cov khoom siv iot hauv tsev, webcams, cov khoom siv hnav tau ntse, thiab kev lag luam automation.
Xaus lus
Yav tom ntej, txoj kev uas peb nyob yuav raug hloov los ntawm Internet of Things, uas yuav xav tau kev sib txuas, thiab kev nce ntxiv ntawm WiFi kuj tseem yuav muab kev tsim kho tshiab zoo rau kev sib txuas ntawm Internet of Things. Raws li kev nce qib tam sim no, WiFi 7 yuav txhim kho daim ntawv thov thiab kev paub txog wireless terminal zoo heev. Tam sim no, cov neeg siv hauv tsev yuav tsis tas yuav ua raws li thiab nrhiav WiFi 7 cov khoom siv, uas tuaj yeem ua lub luag haujlwm tseem ceeb dua rau cov neeg siv kev lag luam.
