Key Takeaways
- Ultra-Wideband tau nyob hauv txhua lub iPhone txij li iPhone 11.
- UWB sai dua, zoo dua, thiab siv lub zog tsawg dua Bluetooth.

UWB AirPods Pro tuaj yeem ua lub suab tsis poob rau ib teev thiab teev.
Ib lub sijhawm tawm tswv yim hauv kev xam phaj tau ua rau muaj kev xav vwm txog lub neej yav tom ntej ntawm AirPods-thiab txhua yam ua rau muaj kev nkag siab tag nrho.
AirPods yog cov khoom siv me me zoo heev. Lawv suab zoo kawg nkaus, lawv koom nrog tag nrho koj cov khoom siv, thiab lawv siv tau yooj yim heev. Tab sis xav txog yog tias lawv txuas nrawm dua, suab zoo dua, thiab tshem tawm qhov kev cuam tshuam cuam tshuam thaum gaming lossis siv suab paj nruag-tsim apps. Qhov ntawd tej zaum yuav ua tau-yog thiab thaum Apple ditches Bluetooth.
"Txiv kuv, peb xav tau kev hloov pauv rau Bluetooth," hais tias Apple nerd thiab podcaster John Siracusa ntawm nws Acidental Tech Podcast. "Bluetooth nqus. Nws tau zoo dua ntau xyoo dhau los, tab sis nws yog qhov tseem ceeb uas cuam tshuam kuv txog lub suab wireless."
Xav Tau Ceev
Hauv kev xam phaj nrog UK's What Hi-Fi magazine, Apple's VP of acoustics, Gary Geaves, tau hais tias nws pab neeg xav tau cov ntaub ntawv bandwidth ntau dua li Bluetooth tuaj yeem muab tau. Tom qab ntawd nws hinted tias twb muaj ib yam dab tsi hauv kev ua haujlwm. Qhov plausible tshaj plaws "ib yam dab tsi" yog Ultra-Wideband xov tooj cua, uas troounces Bluetooth nyob rau hauv txhua yam hais txog, thiab-crucially-tau twb tau tsim rau hauv txhua lub iPhone txij li thaum lub iPhone 11.
Bluetooth tau ua haujlwm zoo rau peb xyoo dhau los, thiab thaum nws zoo rau nas, keyboards, thiab lwm yam khoom siv hluav taws xob qis, nws tawm tsam nrog lub suab. Qhov ntawd yog vim lub suab yuav tsum xa cov ntaub ntawv ntau dua saum huab cua dua li nas. Ntau tshaj li Bluetooth ua tau.
Qhov kev ua haujlwm yog txhawm rau txhawm rau lub suab ua ntej xa nws, tom qab ntawd decompress nws dua hauv lub mloog pob ntseg lossis AirPods nws tus kheej. Nws zoo li ZIP cov ntaub ntawv, tsuas yog rau lub suab. Qhov no muaj ob yam kev mob tshwm sim. Ib qho yog tias lub suab zoo raug kev txom nyem-txawm hais tias niaj hnub codecs (compression / decompression txoj kev) ua haujlwm zoo. Lwm qhov yog qhov kev ua haujlwm compression siv sijhawm, qhia txog kev ncua.
Yog vim li cas cov keyboard kais tau hnov thaum tam sim ntawd, thaum lub suab muaj qeeb me ntsis. Nrog rau kev mloog dav dav, nws tsis muaj qhov loj heev-ib zaug lub suab paj nruag pib, koj tsis pom. Tab sis yog tias koj siv Bluetooth lub mloog pob ntseg los saib xyuas lub suab paj nruag lossis ua si, nws tuaj yeem ua rau muaj kev mob siab lossis ua tsis tau zoo.
Ultra-Wideband xov tooj cua tuaj yeem daws txhua yam ntawm no thiab ntau dua.
UWB
Muaj Ultra-Wideband nti (Apple hu nws U1) hauv txhua lub iPhone rov qab mus rau iPhone 11, nws tau ua txhua yam tab sis tsis muaj txiaj ntsig. U1 ua rau muaj kev ua yeeb yam zoo nkauj thaum koj siv AirDrop thiab tseem cia koj nrhiav cov khoom siv Nrhiav Kuv. Lub HomePod mini muaj U1, ib yam li Apple Watch Series 6 thiab AirTag.
UWB, hais tias ETSI, yog "kev siv thev naus laus zis rau kev xa tawm cov ntaub ntawv siv cov tswv yim uas ua rau muaj kev sib kis ntawm lub xov tooj cua zog tshaj qhov dav dav dav, nrog lub zog qis heev spectral ntom." Thiab raws li cov kws tshawb nrhiav kev tshaj lij Max Tech, nws txhim kho ntawm Bluetooth hauv cov hauv qab no.
Bluetooth qhov siab tshaj plaws hloov pauv ceev yog nyob ib ncig ntawm ob megabits ib ob. Apple's lossless audio codec, uas tseem tsis tau ua haujlwm nrog AirPods, xav tau 9.2 megabits. Thiab UWB? 675 megabits.
Qhov ntawd yog vim Bluetooth tsuas tuaj yeem siv me me 2MHz sliver ntawm xov tooj cua spectrum, piv rau UWB, uas tuaj yeem nthuav tawm mus rau hauv 500MHz-wide band. Qhov ntawd yog nws lub npe los ntawm.
Tib lub sijhawm, UWB kev siv hluav taws xob qis dua, kev sib txuas muaj kev nyab xeeb dua, thiab qhov ntau ntawm qhov kev sib txuas tau ntev dua. Qhov ntawd tsis yog hais tias Apple yuav pov tseg Bluetooth nkaus xwb-tsuas yog rau AirPods, thiab tej zaum kuj yog HomePods. Bluetooth tsim nyog nyob ib puag ncig rau tag nrho lwm cov haujlwm tseem ceeb uas nws tuaj yeem ua tau - thiab nws yog qhov tseem ceeb pub dawb.
"Bluetooth modules me me thiab pheej yig," tech kws sau xov xwm thiab Apple tus neeg siv John Brownlees hais rau Lifewire ntawm tweet. "Vim li cas rhuav tshem kev sib raug zoo rov qab thaum koj tuaj yeem muaj qhov zoo tshaj plaws ntawm ob lub ntiaj teb."
The Whole Enchilada
Tus qauv no tau paub. Apple siv sijhawm ntau xyoo los maj mam muab tso ua ke ib qho zoo dua ntawm qee yam, thiab tom qab ntawd nws tawg mus rau qhov chaw. Qhov piv txwv tsis ntev los no yog M1 nti hauv nws cov khoos phis tawj Mac, uas ntaus txhua yam hauv nws chav kawm, thiab ntau dua.
Apple tuaj yeem ua qhov no vim tias nws tswj hwm txhua qhov kho vajtse thiab software. Yog tias Bose xa UWB earpods, tsis muaj leej twg yuav nyiam vim tsis muaj xov tooj siv tau. Tab sis yog tias Apple ua nws nrog AirPods Pro tom ntej, txhua tus neeg uas muaj iPhone 11 lossis tshiab dua tuaj yeem koom nrog. Thiab koj tuaj yeem twv tau tias Macs tshiab thiab iPads kuj tseem yuav muaj U1 nti yog tias lawv tsis tau.
