I-AT&T ne-T-Mobile zizovala i-3G ukuze kuvuleke indawo ye-5G

Abahlinzeki abangenazintambo bazovala i-3G unyaka wonke, okushiya inombolo engadalulwanga yamadivayisi angasebenzi.
Isikhathi sokuvalelisa ku-3G, ubuchwepheshe obungenawaya obunikeze amafoni ethu ukufinyelela cishe ngokushesha kuwebhu futhi kwasiza ukwenza yonke into kusukela ku-Apple App Store kuya ku-Uber ibe yingxenye yokuphila kwethu kwansuku zonke. Eminyakeni engaphezu kwengu-20 ngemva kokwethulwa kwayo, abahlinzeki besevisi abangenazintambo bacisha i-3G ukuze bavule indlela yomlandeli wayo osheshayo, okhanyayo, i-5G.
Ukwandiswa kwe-5G kuyizindaba ezinhle ngenani elikhulayo labantu abanamadivayisi we-5G, futhi kungaba isinyathelo esibalulekile sokuthola ubuchwepheshe obuthuthuke kakhulu, njengezimoto ezizishayelayo kanye neqiniso elingokoqobo. ubuchwepheshe: konke kusuka kumakhalekhukhwini we-3G kuya ezinhlelweni zesaziso sokushayisana kwezimoto.Kulabo abathembele kulawa madivaysi, ukushintshwa kuzonqamula amanethiwekhi amaselula abathembele kuwo iminyaka eminingi futhi, kwezinye izimo, imishini yokuphepha ebalulekile.
"Inombolo yemishini ye-3G ilokhu yehla kancane kancane," u-Tommaso Melodia, umqondisi we-Wireless Internet of Things Institute e-Northeastern University, utshele i-Recode. qhubeka nokusebenzisa lezi ziteshi eziyigugu ze-3G.Masiyicime.’”
Okufanelekile, abahlinzeki abangenazintambo bangagcina womabili amanethiwekhi e-3G kanye ne-5G esebenza, kodwa i-physics ye-spectrum yomsakazo ubuchwepheshe bamaselula obuthembele kuyo kusho ukuthi izinkampani kufanele zenze izinqumo.I-spectrum yomsakazo ihlanganisa inqwaba yamafrikhwensi asetshenziselwa ukuxhuma yonke into esuka ku-AM/FM. amarediyo kumanethiwekhi e-wifi futhi ilawulwa yi-Federal Communications Commission (FCC).Ngenxa yokuthi i-ejensi inenani elilinganiselwe lamafrikhwensi abekelwe isevisi yeselula, abahlinzeki abangenazintambo kufanele bahlukanise i-spectrum eyabelwe bona ukuze baqhube amanethiwekhi amaningi, okuhlanganisa i-3G, 4G yabo, 5G futhi ekugcineni 6G amasevisi.
I-FCC inikezela ngamabhendi amafrikhwensi amasha kubahlinzeki abangenazintambo ngokusebenzisa izindali ze-spectrum, lapho abahlinzeki abangenazintambo bangabhida amalungelo kumabhendi athile efrikhwensi. .Ngokuvala izizukulwane ezindala zobuchwepheshe bamaselula, izinkampani zingaphinda zisebenzise amaza ukuze zithuthukise amanethiwekhi amasha njenge-4G ne-5G.AT&T izoba ngeyokuqala ukuvala inethiwekhi yayo ye-3G ngoFebruwari 22, ilandelwe yi-T-Mobile ngoJulayi kanye ne-Verizon ekugcineni. zonyaka.
Akuwona wonke umuntu ozothinteka ngokuvalwa kwe-3G.Amafoni amaningi enziwe eminyakeni embalwa edlule aqukethe i-hardware engakwazi ukuxhuma hhayi kumanethiwekhi we-3G kuphela, kodwa futhi ne-4G ne-5G, ngakho ngeke ithinteke.Kodwa asekhona amanye amafoni ingasebenzisa amanethiwekhi e-3G kuphela.Uma i-3G ingaxhumekile ku-inthanethi, lawa madivayisi ngeke akwazi ukuxhuma kunethiwekhi yeselula, okusho ukuthi ngeke akwazi ukuthumela imibhalo, ukushaya amakholi, noma ukufinyelela ku-inthanethi ngaphandle kwe-wifi.Noma yisiphi isexwayiso esiphuthumayo amasevisi athembele ku-3G nawo azoyeka ukusebenza.Lokhu kufaka phakathi izexwayiso ezithile zezokwelapha nezokuphepha, kanye nabasizi abathile bezwi, isofthiwe yokuzulazula nezinhlelo zokuzijabulisa ezakhelwe ezimotweni.I-Older Kindles, iPads kanye nama-Chromebook aklanyelwe ukuxhuma kumanethiwekhi e-3G nawo azothinteka. .
Ngenkathi ukuvalwa kwe-3G kuzoba nemiphumela eminingi, ukwandiswa kwamanethiwekhi athuthuke kakhulu kufanele kuholele ekuvinjeni okungcono nokwamukela amakhasimende asebenzisa imishini ye-4G ne-5G. Ngokusho kwe-Verizon, i-4G ishesha izikhathi ezingu-500 kune-3G, futhi uma ivuliwe ngokugcwele, I-5G kufanele isheshe kakhulu kune-4G.5G izophinda ibe nokubambezeleka okuphansi, okusho ukuthi uma uxhumeke ku-inthanethi, ngeke ube nokubambezeleka. Lokhu kubambezeleka okuphansi kuzokwenza kube lula ukusebenzisa ifoni yakho ngesikhathi sangempela ukwenza izinto eziyinkimbinkimbi. imisebenzi, njengokudlala imidlalo yevidiyo eku-inthanethi noma ukubamba iqhaza emihlanganweni ye-telemedicine ebukhoma.
Ngesikhathi esifanayo, abanikazi bedivayisi ye-3G badinga ukulungiselela ukuvalwa kwe-3G okuzayo.Abanye bangase bangazi nokuthi isevisi yabo isizophuma ku-inthanethi.Ngokuya ngomhlinzeki wabo, lawa makhasimende angaba namasonto noma izinyanga kuphela zokuthuthukisa ubuchwepheshe bawo. okwamanje, akucaci ukuthi bazokwazi yini ukwenza ukushintsha ngesikhathi.
Uma ifoni yakho ixhunywe kunethiwekhi yeselula, ithumela futhi yemukele amasignali kumafrikhwensi anikezwe kuleyo nethiwekhi ethile.Lawa masignali adluliselwa ngalawa maza eziteshini zokudlulisela, njengemibhoshongo yeselula, exhunywe ezintanjeni ze-inthanethi ezihlinzeka ngoxhumo lwenethiwekhi. .Lokhu kufana nendlela ikhompuyutha ephathekayo exhumeka ngayo kunethiwekhi ye-wifi yasekhaya enikwa amandla irutha ye-inthanethi.
E-US, i-3G ngokuvamile isebenza kumafrikhwensi aphakathi kuka-850 MHz no-1900 kuya ku-2100 MHz. Lezi zingxenye ze-spectrum ziwusizo kukho kokubili izwi ledijithali nedatha ye-inthanethi, okuyinto eyenza i-3G yajabulisa kakhulu ngenkathi yethulwa okokuqala ngasekupheleni kwawo-1990. Kusukela ngaleso sikhathi, abathwali abangenazintambo baye bahlakulela imishini emisha kanye nobuchwepheshe obungcono futhi basebenzise ukuqalisa amanethiwekhi abo e-4G kanye ne-5G.Ngenxa yokuthi lawa manethiwekhi angadlulisela idatha eyengeziwe ngesivinini esisheshayo, abahlinzeki abangenazintambo bafuna ukuwaqhuba kuma-frequencies abawasebenzisa njengamanje kumanethiwekhi we-3G. Lokhu kwenzeka kuphela lapho becisha i-3G kwasekuqaleni.
"Kuyinto eyodwa noma inketho," kusho uKevin Ryan, uprofesa wezinhlelo ezingenantambo eStevens Institute of Technology.
Ngaphandle kokuhlelwa kokuthi i-spectrum yomsakazo isebenza kanjani, abahlinzeki abangenazintambo baphinde bahlukanise i-3G spectrum ngoba yenza umqondo wezomnotho kubo.I-Verizon ne-AT&T balinganisela ukuthi ngaphansi kwephesenti elingu-1 lezinsizakalo zisasebenza kumanethiwekhi e-3G, kuyilapho izigidi ezingu-90 zamadivayisi e-5G athunyelwa okokugcina. unyaka wodwa.Uma i-3G igcina isivalile, abahlinzeki abangenazintambo banganikela ngezinsiza ezengeziwe ekwandiseni amanethiwekhi abo e-5G futhi bakholise amakhasimende ukuthi athuthukise izinhlelo zabo zesevisi.
"Abathwali bachitha imali eningi ku-spectrum, futhi kufanele badlulisele lezo zindleko kubathengi.Yingakho sikhokha inani eliphezulu lesevisi yomakhalekhukhwini,” kuchaza u-Sundeep Rangan, umqondisi ohlanganyele we-NYU's Center for Wireless Technology Research.”Labo basebenzisi, abanombono omningi kangaka, bafuna ukuthumela idatha eningi ngangokunokwenzeka, noma basebenzise abasebenzisi abaningi. ngangokunokwenzeka.”
Nakuba ukuvalwa kwe-3G kungase kuzwakale kungazelelwe, akumangazi.Abathwali bayeka ukuthengisa imishini ye-3G eminyakeni embalwa edlule, futhi abaningi bachithe izinyanga ezimbalwa ezedlule bazisa amakhasimende abo e-3G asele ukuthi sekuyisikhathi sokuthuthukisa ubuchwepheshe babo.I-3G bekungeyona inethiwekhi yokuqala. ukuze uye kokungaxhunyiwe ku-inthanethi noma. I-1G inethiwekhi yeselula esekela izisetshenziswa zezwi ze-analog, njengezingcingo ezizitini ezivela kumamuvi wama-80′s - ezingakasebenzi amashumi eminyaka. Nakuba i-T-Mobile isasekela amadivaysi e-2G, kokubili i-Verizon ne-AT&T bavala i-2G yabo. amanethiwekhi eminyakeni embalwa edlule. Ekupheleni kuka-2022, i-3G nayo izonyamalala.
Asazi kahle ukuthi zingaki, kodwa uma i-3G iphela, izigidi zamadivayisi okusebenza kulo lonke elase-US zingashiywa zingaxhumekile. Eziningi zalezi zisetshenziswa ziqukethe ihadiwe engakwazi ukujwayela ukuxhuma kunethiwekhi ye-4G ne-5G.Uma uneyodwa yalezi zisetshenziswa. , bekufanele ngabe uzwe kumhlinzeki wakho ongenazintambo mayelana nezinyathelo zakho ezilandelayo.Nokho, uma ufuna ukuhlola kabili, ungacwaninga idivayisi yakho ethile noma uxhumane nomhlinzeki wakho ongenazintambo.Ungazama futhi ukuhlola izilungiselelo zefoni yakho noma imanuwali yomsebenzisi, noma ugcine iso ekuxhumekeni kwe-4G noma i-5G kudivayisi yakho njengoba wenza usuku lwakho.
Izinhlelo zobuchwepheshe ze-3G ezakhelwe ezimotweni ngokuvamile zisekelwa umhlinzeki omkhulu ongenazintambo, futhi ngokushesha nje lapho lowo mhlinzeki evala ngokusemthethweni isevisi yakhe ye-3G, ayayeka ukusebenza.I-CNBC kanye ne-Consumer Reports ikhiphe uhlu lwamamodeli athintekayo aziwayo, kodwa asikho isizathu sokungakwenzi lokho. hlola nabenzi bezimoto uma kwenzeka.Izimoto ezakhiwe maphakathi nawo-2010 zibonakala zingathinteka kakhulu ngokuvalwa kwe-3G, kodwa ngisho nezimoto ezithile ezikhishwe ngo-2020 zingase zidinge ukuthuthukiswa.
Kukhona nezinye izinsiza ze-3G zezimo eziphuthumayo.Ngaphandle kwamanye amasistimu ezixwayiso zezokwelapha nezokuphepha, amafoni e-3G akhokhelwa kusengaphambili kanye namafoni e-3G avaliwe angashayela u-911 kuphela azobe engaxhunyiwe ku-inthanethi.Abadala asebekhulile, izakhamuzi zasemakhaya, abantu abahola kancane, abangenamakhaya nabasindile. udlame lwasekhaya maningi amathuba okuthi bathembele kule mishini.Njengoba abantu besebenzisa lawa madivaysi kuphela ezimeni ezimbi kakhulu, bangase bangaboni ukuthi kumele bashintshwe kuze kube isikhathi eside ngemva kokuba i-3G icishiwe, okwenza kube nezinkinga ezinkulu zokuphepha.
Yingakho abanye abantu becabanga ukuthi i-3G kufanele ibe ku-inthanethi isikhathi eside.I-AARP ithe lo bhubhane uvimbe abantu abadala abaningi ekubuyekezeni ubuchwepheshe babo futhi ufuna ukubambezela ukuvalwa kuze kuphele unyaka.Izinkampani zama-alamu, kuhlanganise nalezo ezenza umlilo ne-carbon monoxide imitshina kanye nezinhlelo zokuphepha zasekhaya, nazo zicele ukwandiswa.Bathi ukushoda kwama-chip chips kuvimbe imizamo yabo yokukhiqiza nokufaka imishini yokushintsha.
Kodwa akufanele ubheje ngokubambezeleka.Uma unedivayisi ye-3G, manje isikhathi esikahle sokuthuthukisa.Uma wazi othile osebenzisa enye yalezi zisetshenziswa, kuyafaneleka ukuthi uhlole ukuze ubone ukuthi ungamsiza yini ukuthi athole enye.
Umlando ubonisa nakanjani ukuthi amanethiwekhi amaselula ayafika aphinde adlule.Inethiwekhi elandelayo yamaselula, i-6G, ingase ibe ngaphansi kweminyaka engu-10, futhi ingase isetshenziselwe ukwethula yonke into kusukela kumahologramu e-3D kuya ezingutsheni ezixhunyiwe. Ngaleso sikhathi, i-5G ibonakala ingasha futhi ijabulisa futhi izinsuku ze-4G zingase ziphelile.
Izigidi zabantu ziphendukela kuVox ukuze zithole ukuthi kwenzakalani ezindabeni.Umgomo wethu awukaze ube obaluleke kakhulu: ukuhlomisa ngokuqonda.Iminikelo yezimali evela kubafundi bethu iyingxenye ebalulekile yokweseka umsebenzi wethu odinga izinsiza futhi isisiza ukuthi senze izinsiza zezindaba zibe mahhala. kubo bonke.Sicela ucabange ukufaka isandla kuVox namuhla.
