Key Takeaways

  • Google tshaj tawm tab tom ua haujlwm los nqa UWB kev txhawb nqa rau yav tom ntej Pixel cov khoom siv.
  • Smartphones thiab cov khoom siv hauv tsev los ntawm Apple, Samsung, thiab lwm cov tuam ntxhab twb suav nrog kev txhawb nqa rau UWB.
  • Nrog kev txhawb nqa dav dua, cov kws tshaj lij ntseeg tias UWB tuaj yeem txhim kho qhov peb cuam tshuam nrog cov cuab yeej ntse hauv peb lub neej.

Ultra-wideband (UWB) yog ib qho kev nthuav dav uas maj mam tau txais kev txhawb nqa ntau thiab ntau dua. Cov kws tshaj lij hais tias nws tuaj yeem ua rau muaj kev sib txuas zoo dua yav tom ntej.

Kev sib txuas txuas ntxiv yog qhov tseem ceeb ntawm peb lub neej, tshwj xeeb tshaj yog thaum peb txav mus tob rau hauv lub sijhawm uas Internet ntawm Yam (IoT) loj hlob sai. Raws li peb txuas nrog ntau cov khoom siv, muaj peev xwm txuas nrog qhov tseeb thiab kev ruaj ntseg ua qhov tseem ceeb dua. Yog vim li cas UWB kev sib txuas lus yog lub ntsiab lus tseem ceeb ntawm kev sib tham. Cov tuam txhab tsim khoom lag luam tseem ceeb twb tau txav los txhawb nws ntau dua-ob Apple thiab Samsung muaj cov khoom siv nrog UWB, thiab Google tau tshaj tawm tias tab tom ua haujlwm coj nws mus rau lub xov tooj Pixel yav tom ntej.

"Ultra-Wideband (UWB) yog lub tshuab xov tooj cua zoo ib yam li Bluetooth Tsawg Zog (BLE) lossis Wi-Fi. Txawm li cas los xij, UWB muaj ntau yam uas tau teeb tsa sib nrug, "Roy Johnson, tus kws tshaj lij kev sib txuas nrog Allegion, piav qhia hauv email. "UWB muab qhov tseeb qhov chaw uas tseem muaj kev ruaj ntseg zoo heev."

Tawm Tsam Nrog Kev Ua Haujlwm

Ib qhov zoo tshaj plaws UWB coj los rau hauv lub rooj yog qis zog siv. Johnson hais tias UWB tuaj yeem xa qhov tawg luv ntawm RF lub zog hla ntau zaus, uas tso cai rau nws ua haujlwm tau zoo dua li lwm yam kev sib txuas thev naus laus zis.

"Lub transmitter hauv UWB system siv lub zog me me piv rau lwm cov thev naus laus zis," Johnson piav qhia. "Vim tias lub zog spectral ntawm UWB tau faib dav dav nws muaj qis heev xa hluav taws xob theem ntawm txhua zaus."

Qhov kev ua tau zoo no kuj coj tau lwm yam txiaj ntsig. Vim UWB tsis siv thawj zaus Wi-Fi thiab Bluetooth siv, nws tsis tas yuav tawm tsam nrog lwm cov khoom siv hluav taws xob uas xav tau cov zaus ntawd. Congestion twb yog ib qho teeb meem loj ntawm kev siv ntau tshaj plaws xws li 2.4GHz, uas muaj ntau lub wireless routers tseem siv vim nws tuaj yeem xa mus ntev dua thiab nkag mus rau phab ntsa thiab rooj tog. Hmoov tsis zoo, vim tias muaj kev kub ntxhov, Wi-nkaus tsis zoo li nws ua tau lossis yuav tsum yog.

Nrhiav Lub Hom Phiaj Tshiab

Thaum UWB pib pib ua lub thev naus laus zis rau kev sib txuas lus cov ntaub ntawv siab-a la Wi-Fi-nws tau hloov zuj zus los ua ntau dua ntawm kev hnov cov thev naus laus zis raws li kev coj ntawm FiRa Consortium. FiRa tau mob siab los nqa UWB kev txhawb nqa dav dav rau cov khoom siv, thaum tsom mus rau kev ua haujlwm hnyav ntawm cov neeg siv kev paub thiab kev sib cuam tshuam.

Yog vim li cas nws ua haujlwm zoo rau qhov no yog vim qhov luv luv nws xa tawm. Raws li Samsung, cov kev tawg no yog kwv yees li 2 nanoseconds, tso cai rau UWB system hauv cov khoom siv kom khaws cov ncauj lus kom ntxaws txog cov khoom nyob qhov twg, es tsis txhob tos ntau lub vib nas this lossis txawm feeb rau qhov hloov tshiab rau txoj haujlwm.

Qhov kev poob qis, txawm li cas los xij, yog UWB muaj qhov txwv deb. Txawm li cas los xij, muaj ntau cov ntawv thov uas nws tuaj yeem siv rau yav tom ntej. Txawm hais tias cov yam ntxwv pom tseeb tshaj plaws zoo ib yam li cov uas peb twb pom-cov yuam sij uas qhib koj lub qhov rooj thaum koj mus txog nws, lossis lub qhov rooj tsheb uas qhib tau thaum koj tsav tsheb-lwm tus muaj ntau dua nuanced.

"Ib lub tshuab xa hluav taws xob UWB tuaj yeem ncav cuag koj lub xov tooj- tsuav nws tsis nyob deb dhau-thiab xa lus ceeb toom uas tuaj yeem hu rau cov kev pabcuam xwm txheej kub ntxhov lossis tub ceev xwm," Rex Freiberger, tus kws tshaj lij ntawm cov cuab yeej ntse thiab CEO ntawm Gadget Review, hais rau Lifewire hauv email.

Freiberger tseem sau tseg tias tsev kho mob yog cov neeg sib tw tseem ceeb rau hom thev naus laus zis no, vim lawv tuaj yeem siv nws los taug qab cov neeg mob nyob qhov twg, lawv nyob ze li cas, thiab ntau dua.

Kev Sib Tw Ua Ntej

Raws li nrog cov thev naus laus zis tshiab, muaj qee qhov kev sib tw ua ntej. Ib qho kev txhawj xeeb loj tshaj plaws yog tias cov khoom siv sib txawv tuaj yeem ua rau muaj teeb meem nrog kev sib cuam tshuam, nyob ntawm seb lawv UWB cov tshuab ua haujlwm li cas.

Vim tias lub zog spectral ntawm UWB tau faib dav dav nws muaj cov xaim hluav taws xob tsawg heev ntawm txhua zaus.

"Kev txais yuav UWB tau nrawm nrawm nrog cov ntaub ntawv siv los ntawm kev nkag mus rau kev them nyiaj thiab ntau dua," Johnson hais. "Lub peev xwm dav dav no ua ke nrog kev sib koom ua lag luam muaj zog thiab kev tsom mus rau kev sib koom tes yog qhov tseem ceeb. Ib qho kev pheej hmoo tuaj yeem yog cov cuab yeej muaj peev xwm UWB tsis tuaj yeem ua haujlwm ua ke lossis nkag siab ib leeg."

Zoo hmoo, Johnson hais tias, FiRa Consortium tab tom ua haujlwm hnyav kom ntseeg tau tias qhov no tsis yog qhov teeb meem yav tom ntej.
