AT&T thiab T-Mobile yuav kaw 3G los ua chaw rau 5G

Cov chaw muab kev pabcuam wireless yuav kaw 3G thoob plaws hauv lub xyoo, ua rau muaj tus lej xov tooj tsis tau qhia tawm ntawm kev pabcuam.
Nws yog lub sijhawm hais lus zoo rau 3G, thev naus laus zis thev naus laus zis uas muab peb lub xov tooj yuav luag tam sim nkag mus rau hauv lub vev xaib thiab pab ua txhua yam los ntawm Apple App Store mus rau Uber yog ib feem ntawm peb lub neej niaj hnub. Ntau tshaj 20 xyoo tom qab nws tso tawm, cov chaw muab kev pabcuam wireless. tab tom tua 3G kom tshem tawm txoj hauv kev rau nws sai, flashier successor, 5G.
Kev nthuav dav ntawm 5G yog xov xwm zoo rau cov neeg coob coob nrog 5G cov khoom siv, thiab nws tuaj yeem yog kauj ruam tseem ceeb rau kev siv thev naus laus zis ntau dua, xws li tsheb tsav tus kheej thiab kev muaj tiag virtual.Tab sis kaw 3G tseem yuav cuam tshuam tag nrho tiam ntawm thev naus laus zis: txhua yam ntawm 3G xov tooj ntawm tes mus rau kev ceeb toom tsheb sib tsoo.Rau cov neeg uas tso siab rau cov cuab yeej no, kev hloov pauv yuav txiav tawm cov xov tooj ntawm tes uas lawv tau tso siab rau ntau xyoo thiab, qee zaum, cov cuab yeej siv kev ruaj ntseg tseem ceeb.
Tommaso Melodia, tus thawj coj ntawm Wireless Internet of Things Institute ntawm Northeastern University, hais rau Recode. "Tam sim no cov neeg nqa khoom tau pib hais tias, 'Nws tsis muaj txiaj ntsig zoo rau peb. khaws cia siv cov channel muaj nuj nqis no rau 3G.Cia peb muab nws tua.'
Qhov zoo tshaj plaws, cov chaw muab kev pabcuam wireless tuaj yeem khaws ob qho tib si 3G thiab 5G tes hauj lwm nce thiab khiav, tab sis lub physics ntawm lub xov tooj cua spectrum uas cellular technology tso siab rau txhais tau tias cov tuam txhab yuav tsum xaiv.Lub xov tooj cua spectrum suav nrog ntau qhov ntau zaus siv los txuas txhua yam ntawm AM / FM. Cov xov tooj cua rau wifi tes hauj lwm thiab tau tswj hwm los ntawm Tsoom Fwv Teb Chaws Kev Sib Txuas Lus Commission (FCC).Vim tias lub koom haum muaj tsawg zaus tshwj tseg rau cov kev pabcuam ntawm tes, cov chaw muab kev pabcuam wireless yuav tsum faib cov spectrum faib rau lawv kom khiav ntau lub network, suav nrog lawv 3G, 4G, 5G thiab thaum kawg 6G kev pabcuam.
FCC muab cov zaus bands tshiab rau cov chaw muab kev pabcuam wireless los ntawm kev sib tw spectrum, thaum lub sijhawm cov chaw muab kev pabcuam wireless tuaj yeem twv rau cov cai rau qee zaus bands.Tab sis cov kev sib tw yeej tuaj yeem khiav mus rau ntau lab, yog li cov chaw muab kev pabcuam sim siv cov spectrum uas lawv twb muaj kom ua tau zoo. .Los ntawm kev tua cov neeg laus ntawm cov thev naus laus zis thev naus laus zis, cov tuam txhab tuaj yeem rov tsim cov zaus los txhim kho cov tes hauj lwm tshiab xws li 4G thiab 5G.AT&T yuav yog thawj zaug kaw nws lub 3G network thaum Lub Ob Hlis 22, ua raws li T-Mobile thaum Lub Xya Hli thiab Verizon thaum kawg. ntawm lub xyoo.
Tsis yog txhua tus neeg yuav raug cuam tshuam los ntawm 3G kaw.Ntau lub xov tooj tau tsim nyob rau ob peb xyoos dhau los muaj cov khoom siv uas tuaj yeem txuas tsis tau rau 3G tes hauj lwm, tab sis kuj 4G thiab 5G, yog li lawv yuav tsis cuam tshuam.Tab sis tseem muaj qee lub xov tooj uas. tsuas siv tau 3G tes hauj lwm xwb.Thaum 3G mus offline, cov cuab yeej no yuav tsis muaj peev xwm txuas mus rau lub xov tooj ntawm tes, uas txhais tau tias lawv yuav tsis muaj peev xwm xa ntawv, hu, lossis nkag hauv internet yam tsis muaj wifi.Txhua yam kev ceeb toom xwm txheej ceev Cov kev pabcuam uas vam khom rau 3G kuj tseem yuav tsum tsis ua haujlwm.Cov no suav nrog qee qhov kev ceeb toom kev kho mob thiab kev nyab xeeb, nrog rau qee lub suab pabcuam, navigation software thiab kev lom zem ua rau hauv tsheb.Kindle qub, iPads thiab Chromebooks tsim los txuas rau 3G tes hauj lwm tseem yuav cuam tshuam. .
Thaum lub 3G kaw yuav muaj ntau qhov tshwm sim, kev nthuav dav ntawm kev sib txuas ntau dua yuav tsum ua kom muaj kev nrawm dua thiab txais tos rau cov neeg siv khoom siv 4G thiab 5G. Raws li Verizon, 4G yog 500 zaus sai dua 3G, thiab ib zaug tag nrho qhib, 5G yuav tsum ceev dua 4G.5G tseem yuav muaj qis dua latency, txhais tau tias thaum koj txuas nrog hauv internet, koj yuav muaj qhov tsis muaj lag luam.Qhov qis latency no yuav ua rau nws yooj yim dua rau kev siv koj lub xov tooj ntawm lub sijhawm ua haujlwm. cov dej num, xws li kev ua si hauv online video games lossis koom nrog cov rooj sib tham hauv telemedicine.
Nyob rau tib lub sijhawm, 3G cov tswv cuab yuav tsum tau npaj rau qhov kev kaw 3G uas yuav tshwm sim.Ib txhia yuav tsis paub tias lawv cov kev pabcuam tab tom yuav mus offline.Raws li lawv cov neeg muab kev pabcuam, cov neeg siv khoom no tsuas muaj lub lis piam lossis ntau hli los txhim kho lawv cov thev naus laus zis.At lub sijhawm no, nws tsis paub meej tias lawv puas tuaj yeem hloov kho lub sijhawm.
Thaum koj lub xov tooj txuas nrog lub xov tooj ntawm tes, nws xa thiab tau txais cov teeb liab ntawm cov zaus uas tau muab rau lub network tshwj xeeb.Cov teeb liab no tau xa mus rau cov zaus no mus rau cov chaw nres tsheb, xws li xov tooj ntawm tes, uas txuas nrog internet cables uas muab kev sib txuas hauv network. .Qhov no zoo ib yam li lub laptop txuas nrog lub tsev wifi network siv los ntawm lub router internet.
Hauv Teb Chaws Asmeskas, 3G feem ntau ua haujlwm ntawm ntau zaus ntawm 850 MHz thiab 1900 txog 2100 MHz.Cov ntu ntawm cov spectrum no muaj txiaj ntsig zoo rau ob lub suab digital thiab Internet cov ntaub ntawv, uas yog qhov ua rau 3G zoo siab heev thaum nws thawj zaug pib thaum xyoo 1990s lig. Txij thaum ntawd los, cov tuam txhab wireless tau tsim cov cuab yeej tshiab thiab thev naus laus zis zoo dua thiab siv lawv los tsim lawv cov 4G thiab 5G tes hauj lwm.Vim tias cov tes hauj lwm no tuaj yeem xa cov ntaub ntawv ntau dua ntawm qhov nrawm dua, cov chaw muab wireless xav khiav lawv ntawm cov zaus lawv tam sim no siv rau 3G tes hauj lwm. Qhov no tsuas yog tshwm sim thaum lawv tua 3G thawj qhov chaw.
"Nws yog ib qho kev xaiv los yog kev xaiv," said Kevin Ryan, tus xibfwb ntawm wireless systems ntawm Stevens Institute of Technology.
Tshaj li kev thauj mus los ntawm kev siv xov tooj cua spectrum ua haujlwm li cas, cov chaw muab kev pabcuam wireless tseem tab tom hloov kho 3G spectrum vim tias nws ua rau muaj kev lag luam ntau rau lawv.Verizon thiab AT&T kwv yees tias tsawg dua 1 feem pua ​​​​ntawm cov kev pabcuam tseem khiav ntawm 3G tes hauj lwm, thaum 90 lab 5G cov khoom xa tawm kawg. Ib xyoos ib leeg.Thaum 3G thaum kawg kaw lawm, cov chaw muab kev pabcuam wireless tuaj yeem siv ntau cov peev txheej los nthuav lawv 5G tes hauj lwm thiab txhawb cov neeg siv khoom kom hloov kho lawv cov phiaj xwm kev pabcuam.
"Cov neeg nqa khoom siv nyiaj ntau ntawm spectrum, thiab lawv yuav tsum dhau cov nqi rau cov neeg siv khoom.Tias yog vim li cas peb them tus nqi siab rau kev pabcuam xov tooj ntawm tes, "hais Sundeep Rangan, tus thawj coj ntawm NYU's Center for Wireless Technology Research. raws li ua tau."
Thaum lub 3G kaw tej zaum yuav hnov ​​​​dheev, nws tsis yog qhov xav tsis thoob. Cov neeg nqa khoom tau tso tseg cov khoom siv 3G ob peb xyoos dhau los, thiab ntau tus tau siv ob peb lub hlis dhau los ceeb toom rau lawv cov neeg siv khoom 3G tseem tshuav tias nws yog lub sijhawm los txhim kho lawv cov thev naus laus zis.3G tsis yog thawj lub network. mus offline los yog.1G yog lub xov tooj ntawm tes uas txhawb nqa cov khoom siv suab analog, zoo li cov xov tooj cib los ntawm 80's tsos - uas tsis tau ua haujlwm ntau xyoo lawm.Txawm tias T-Mobile tseem txhawb nqa 2G li, Verizon thiab AT&T kaw lawv 2G. tes hauj lwm ob peb xyoos dhau los.Thaum kawg ntawm 2022, 3G tseem yuav ploj mus.
Peb tsis paub tseeb tias muaj pes tsawg, tab sis thaum 3G tso tseg, ntau lab ntawm cov khoom siv khiav lag luam thoob plaws Tebchaws Meskas yuav raug tso tseg tsis txuas.Ntau yam ntawm cov khoom siv no muaj cov khoom siv kho vajtse uas tsis tuaj yeem hloov mus rau 4G thiab 5G networks.Yog tias koj muaj ib qho ntawm cov khoom siv no. , koj yuav tsum tau hnov ​​​​los ntawm koj tus neeg muab kev pabcuam wireless txog koj cov kauj ruam tom ntej.Txawm li cas los xij, yog tias koj xav tau ob npaug ntxiv, koj tuaj yeem tshawb xyuas koj lub cuab yeej tshwj xeeb lossis tiv tauj koj tus kws kho mob wireless.Koj tuaj yeem sim kuaj koj lub xov tooj qhov chaw lossis cov neeg siv phau ntawv, lossis khaws cia. ib qhov muag tawm rau 4G lossis 5G kev sib txuas ntawm koj lub cuab yeej thaum koj mus txog koj hnub.
3G thev naus laus zis tshuab tsim rau hauv tsheb feem ntau yog kev txhawb nqa los ntawm cov chaw muab kev pabcuam tseem ceeb, thiab sai li sai tau thaum tus kws kho mob kaw nws cov kev pabcuam 3G, lawv tsis ua haujlwm. tshawb xyuas nrog cov kws tsim khoom siv hluav taws xob tsuas yog nyob rau hauv rooj plaub.Lub tsheb tsim hauv nruab nrab xyoo 2010 zoo li feem ntau yuav cuam tshuam los ntawm 3G kaw, tab sis txawm tias qee lub tsheb tso tawm xyoo 2020 yuav xav tau kev hloov kho tshiab.
Kuj tseem muaj qee qhov 3G cov khoom siv rau xwm txheej ceev.Tshwj tsis yog qee qhov kev ceeb toom kev kho mob thiab kev nyab xeeb, xov tooj 3G them ua ntej thiab kaw lub xov tooj 3G uas tsuas tuaj yeem hu rau 911 xwb yuav offline. Cov laus, cov neeg nyob deb nroog, cov neeg tau nyiaj tsawg, cov neeg tsis muaj tsev nyob thiab cov neeg muaj sia nyob. Kev tsim txom hauv tsev feem ntau yuav vam khom cov cuab yeej no.Vim tib neeg tsuas yog siv cov cuab yeej no thaum muaj xwm txheej hnyav, lawv yuav tsis paub tias lawv yuav tsum tau hloov mus txog rau ntev tom qab 3G raug kaw, tsim teeb meem kev nyab xeeb loj.
Tias yog vim li cas qee tus neeg xav tias 3G yuav tsum nyob online ntev dua.AARP tau hais tias tus kabmob kis tau zoo tiv thaiv ntau tus neeg laus los ntawm kev hloov kho lawv cov thev naus laus zis thiab xav ncua kev kaw mus txog rau thaum xaus ntawm lub xyoo.Tswb cov tuam txhab, suav nrog cov uas ua rau hluav taws thiab carbon monoxide. Cov cuab yeej ntes thiab cov tshuab kev ruaj ntseg hauv tsev, kuj tau thov kom muaj kev txuas ntxiv.Lawv hais tias qhov tsis txaus ntawm lub khoos phis tawj chips tau cuam tshuam lawv cov kev siv zog los tsim thiab nruab cov khoom siv hloov pauv.
Tab sis koj yuav tsum tsis txhob bet rau ncua sij hawm.Yog hais tias koj muaj ib tug 3G ntaus ntawv, tam sim no yog lub zoo meej lub sij hawm rau upgrade.Yog hais tias koj paub ib tug neeg uas siv ib tug ntawm cov pab kiag li lawm, nws yog tsim nyog mus xyuas seb koj yuav pab tau lawv nrhiav tau ib tug hloov.
Keeb kwm inevitably qhia tau hais tias cellular networks tuaj thiab mus.Qhov tom ntej cellular network, 6G, tej zaum yuav tsawg tshaj li 10 xyoo, thiab nws yuav siv tau los qhia txhua yam los ntawm 3D holograms rau kev sib txuas khaub ncaws. thiab hnub ntawm 4G yuav dhau mus.
Ntau lab tus tib neeg tig mus rau Vox kom paub seb muaj dab tsi tshwm sim hauv xov xwm.Peb lub hom phiaj tseem tsis tau muaj qhov tseem ceeb dua: kev txhawb nqa los ntawm kev nkag siab. Kev pab nyiaj txiag los ntawm peb cov neeg nyeem yog ib feem tseem ceeb ntawm kev txhawb nqa peb cov peev txheej ua haujlwm thiab pab peb ua cov kev pabcuam xov xwm dawb rau txhua tus.Thov txiav txim siab pab rau Vox hnub no.
