Key Takeaways
- Lub thev naus laus zis los hloov cov xov tooj cua mus rau hauv lub zog muaj thiab twb tau siv rau qee kis.
- Cov kws tshaj lij ntseeg tias kev them nyiaj RF tuaj yeem ua rau qhov kawg ntawm cov hluav taws xob cables lossis txawm tias xaus rau kev txhawj xeeb txog kev them tag nrho.

Raws li cov kws tshaj lij, kev siv dav dav ntawm kev them nyiaj RF tseem yog ib txoj hauv kev tawm, ua tsaug rau kev them nqi qis dua thiab nce nqi zog piv rau cov qauv tam sim no.
Xov tooj cua zaus (RF) them tag nrho ditches qhov xav tau rau cov cables lossis plugs-uas tuaj yeem ua rau wireless charging tiag tiag rau txhua yam khoom siv hluav taws xob me me.
Tsis txhob tsis meej pem nrog inductive / wireless charging, uas yuav tsum tau them lub ncoo lossis chaw nres nkoj, RF charging siv lub kav hlau txais xov embedded los hloov cov xov tooj cua qis rau hauv lub zog. Samsung twb tau siv nws nrog cov chaw taws teeb rau nws cov tshiab 2022 Smart TVs, txawm hais tias lawv tuaj yeem them nyiaj ntawm hnub ci zog lossis USB-C. Hauv txoj kev xav, qhov no tsim qhov xwm txheej uas qhov chaw taws teeb yuav tsis muaj zog tiag tiag. Tab sis vim li cas thiaj nres ntawm cov chaw taws teeb? RF charging puas tuaj yeem siv rau lwm yam khoom siv hluav taws xob me me uas yuav tsum tau siv lub zog me me?
"Nws muaj peev xwm pom tau tias cov thev naus laus zis zoo li no txuas ntxiv dhau ntawm Samsung's Smart TV cov chaw taws teeb rau hauv cov neeg siv khoom lag luam dav dav," pom zoo Stephen Curry, CEO ntawm cov kev pabcuam kos npe digital CocoSign, hauv email rau Lifewire. "Cov tuam txhab xws li Powercast tau pom zoo rau kev them nyiaj wireless ntev siv 915-MHz kev lag luam, kev tshawb fawb, thiab cov khoom siv kho mob los tshaj tawm RF lub zog rau cov khoom siv sib xws."
The possibilities
TV cov chaw taws teeb feem ntau tsis siv ntau lub zog-feem ntau tsawg dua 2V-yog li siv RF them kom nws lub zog zoo li tsim nyog. Tshwj xeeb tshaj yog thaum saib cov piv txwv ntawm RF txais, uas tuaj yeem tso tawm ntawm 4.2V thiab 5.5V, muaj zog txaus rau tus qauv TV chaw taws teeb. Qhov no kuj tseem siv tau rau lwm cov khoom siv hluav taws xob me me uas yuav khaws cia ze ntawm Wi-Fi router, xws li cov tswj kev ua si lossis tej zaum txawm tias smartphones.
"Kev siv xov tooj cua nthwv dej los them cov khoom siv no yog lub tswv yim zoo thiab yuav ua tau vim tias lawv yog cov khoom siv qis thiab txij li lub zog ntawd mus pov tseg lwm yam," Curry hais. "Hais txog kev sib raug zoo ntawm cov khoom siv, kev them nyiaj RF tsis txwv los ntawm kev txwv lub cev thiab cov duab raws li cov neeg tsim khoom tuaj yeem tsim tus txais hauv cov khoom me me."
Yog li kev them nyiaj RF tuaj yeem ua haujlwm nrog cov khoom siv hluav taws xob me me feem ntau vim tias qhov kev sib tw tiag tiag tsuas yog sib txuas tus txais. Tab sis raws li Curry taw qhia, kev siv dav ntawm RF them nyiaj kuj tseem cuam tshuam rau peb txoj kev sib raug zoo nrog cov khoom siv no. Peb tsis tas yuav cuam tshuam nrog cov cables lossis txawm tias yuav tsum nrhiav chaw them nyiaj thawj zaug. Thiab, txij li nws tsuas yog siv xov tooj cua tsis muaj zog, ntau yam khoom siv tuaj yeem raug them ib txhij.
"Kev siv dav dav ntawm wireless charging technologies zoo li RF charging yuav txhim kho qhov chaw ua haujlwm, "Curry tau hais tias, "los ntawm kev muab kev txav mus los kom zoo thiab tshem tawm cov roj teeb uas tsis tshua muaj kev ntxhov siab cuam tshuam nrog kev them nyiaj."
Cov Limitations
Nyob rau hauv nws lub xeev tam sim no, RF them tseem muaj qee qhov kev tsis zoo-tsuas yog tsis tuaj yeem siv lub zog loj dua, uas yog. Raws li Tian sau tseg, kev siv cov xov tooj cua tsis tshua muaj suab nrov raws li kev siv lub zog txwv lub zog uas tuaj yeem hloov pauv. Yog li thaum nws yuav tsis xav tau cov cables lossis lub ncoo induction, nws kuj yuav tsis them cov khoom siv sai li qhov kev xaiv.
"Lub xov tooj cua tsis muaj qhov zaus tsawg, vim tias lawv tsis tuaj yeem hloov pauv cov ntaub ntawv ntau lossis lub zog ib zaug," Jonathan Tian, Co-Founder ntawm smartphone daws teeb meem Mobitrix, hauv email rau Lifewire. "Vim qhov no, qhov ceev ntawm kev them nyiaj yuav qis heev piv rau kev them nyiaj ntawm ultrasound nthwv dej."
Raws li Tian, tus nqi yog lwm qhov teeb meem RF them tseem yuav tsum tau kov yeej. Tshwj xeeb tshaj yog, nws yuav raug nqi cov neeg siv nyiaj ntau dua kom them nyiaj ntau dua (xws li smartphones) nrog cov xov tooj cua. Qhov no txhais tau tias nws yuav yog qee lub sijhawm ua ntej peb pom cov thev naus laus zis tshwm sim hauv cov khoom siv hluav taws xob ntau dua.
"Kev siv xov tooj cua nthwv dej rau kev them nqi yog kim dhau piv rau kev them nyiaj wireless," Tian hais. "Ib tug yuav tsum them li 50% ntau dua los them lawv cov cuab yeej siv xov tooj cua nthwv dej. Txawm li cas los xij, xov tooj cua tsis tau siv 50% ntau zog dua li ultrasound nthwv dej [xws li induction charging]."
Raws li kev cog lus raws li kev them nyiaj RF tej zaum yuav yog, nws yuav siv sij hawm qee lub sijhawm rau nws los ua ntau dua hauv cov neeg siv khoom siv. Tom qab tag nrho, rau qhov nthuav dav li ib yam dab tsi zoo li Qi wireless charging tau dhau los, nws tsis tau ua li ntawd thaum hmo ntuj. Nws siv ntau xyoo ntawm kev txhim kho thiab kev saws me nyuam los ntawm ntau lub tuam txhab kho vajtse. RF them kuj tseem tuaj yeem mus txog qhov ntawd, tab sis tej zaum peb yuav tau tos ntev dua.
