Nekutumirwa kwe4G uye 5G network, 2G uye 3G basa rekunze munyika dzakawanda uye matunhu ari kufambira mberi zvakatsiga. Ichi chinyorwa chinopa tarisiro ye2G uye 3G offline maitiro pasi rese.
Sezvo 5G network ichiramba ichiiswa pasi rose, 2G uye 3G iri kusvika kumagumo. 2G uye 3G kudzikisira kuchave nekukanganisa kweiyo iot deployments uchishandisa aya matekinoroji. Pano, isu tichakurukura nyaya dzinofanirwa kutariswa nemabhizinesi panguva ye2G/3G offline maitiro uye mapikisi.
Iko kukanganiswa kwe2G uye 3G isina mhepo pane iot yekubatanidza uye nhanho dzekupikisa
Sezvo 4G ne5G dziri kushandiswa pasi rose, 2G uye 3G basa rekunze munyika dzakawanda nematunhu riri kufambira mberi zvakatsiga. Iyo nzira yekudzima network inosiyana nenyika nenyika, kungave pakufunga kwevatongi venzvimbo kuti vasunungure zvakakosha zviwanikwa, kana pakufunga kwevanofambisa nharembozha kuti vavhare mambure apo masevhisi aripo haapembedzi kuramba achishanda.
2G network, iyo yave ichitengeswa kweanopfuura makore 30, inopa yakakura chikuva chekuendesa emhando iot mhinduro pachiyero chenyika nepasirese. Hupenyu hurefu hwekutenderera kweakawanda iot mhinduro, kazhinji kupfuura makore gumi, zvinoreva kuti kuchine nhamba huru yemidziyo inogona kushandisa 2G network chete. Nekuda kweizvozvo, matanho anofanirwa kutorwa kuti ave nechokwadi chekuti iot mhinduro dzinoramba dzichishanda kana 2G ne3G dzisiri pamhepo.
2G uye 3G kudzikisira kwakatangwa kana kupedzwa mune dzimwe nyika, seUS neAustralia. Mazuva anosiyana zvakanyanya kune dzimwe nzvimbo, uye vazhinji veEurope vakagadzirirwa kuguma kwe 2025. Mukufamba kwenguva, 2G uye 3G mitambo ichapedzisira yabuda pamusika zvachose, saka iyi idambudziko risingadzivisiki.
Maitiro e2G/3G unplugging anosiyana kubva munzvimbo nenzvimbo, zvichienderana nehunhu hwemusika wega wega. Nyika dzakawanda uye matunhu akazivisa zvirongwa zve2G uye 3G pasina Indaneti. Huwandu hwemanetwork akavharwa hucharamba huchiwedzera. Anopfuura makumi mashanu neshanu 2G uye 3G network anofungidzirwa kuvharwa pakati pa2021 na2025, maererano neGSMA Intelligence data, asi matekinoroji maviri haafanire kubviswa panguva imwe chete. Mune mamwe misika, 2G inotarisirwa kuenderera mberi ichishanda kwemakore gumi kana kupfuura, semasevhisi chaiwo akadai sekubhadhara nhare muAfrica uye masisitimu ekufona kwemotokari (eCall) mune mamwe misika anovimba ne2G network. Muzviitiko izvi, 2G network inogona kuramba ichishanda kwenguva yakareba.
3G ichasiya riini pamusika?
Chikamu chekubuda che3G network chakarongwa kwemakore uye chakadzimwa munyika dzakawanda. Misika iyi yakawana zvakanyanya kuvharwa kwe4G uye iri pamberi pepakiti mukutumirwa kwe5G, saka zvine musoro kuvhara 3G network uye kuendesa spectrum kune inotevera-chizvarwa matekinoroji.
Kusvika ikozvino, mamwe 3G network akavharwa muEurope kupfuura 2G, uye mumwe mufambisi muDenmark akavhara 3G network mu 2015. Maererano neGSMA Intelligence, huwandu hwevashandi ve19 munyika dze14 dzeEurope vanoronga kuvhara ma 3G network ne. 2025, nepo vasere chete vari munyika sere vanoronga kuvhara 2G network yavo panguva imwe chete. Huwandu hwekuvhara network huri kukura sezvo vatakuri vanoratidza zvirongwa zvavo. Europe's 3G network shutdown Mushure mekunyatsoronga, vashandisi vazhinji vakazivisa mazuva avo ekudzima 3G. Chimiro chitsva chiri kubuda muEurope ndechekuti vamwe vashandisi vari kuwedzera iyo yakarongwa yekumhanya nguva ye2G. MuUK, semuenzaniso, ruzivo rwazvino rwunoratidza kuti zuva rakarongwa rekuburitsa 2025 rakadzoserwa kumashure nekuti hurumende yaita chibvumirano nevashandisi venhare kuchengetedza 2G network ichimhanya kwemakore mashoma anotevera.
· Manetiweki eAmerica e3G akavharwa
Iyo 3G network yekuvhara muUnited States iri kufambira mberi zvakanaka nekutumirwa kwe4G uye 5G network, ine zvese zvinotakura zvinotakura zvinovavarira kupedzisa kuburitswa kwe3G pakupera kwa 2022. Mumakore apfuura, dunhu reAmerica rakatarisa kuderedzwa kwe2G sevatakuri. yakaburitsa 5G. Vashandi vari kushandisa spectrum yakasunungurwa ne 2G kubudiswa kuti iite nekudiwa kwe 4G uye 5G network.
· Asia's 2G network inovhara maitiro
Vanopa masevhisi muAsia vari kuchengeta 3G network uku vachivhara 2G network kuti vapezve spectrum kune 4G network, ayo anoshandiswa zvakanyanya mudunhu. Pakupera kwa2025, GSMA Intelligence inotarisira kuti vashandisi makumi maviri nevapfumbamwe vavhare 29 network yavo uye gumi nematanhatu kudzima 3G network. Iyo chete dunhu muAsia yakavhara yayo 2G (2017) uye 3G (2018) network iTaiwan.
MuAsia, pane zvimwe zvinosiya: vashandisi vakatanga 3G kudzikisira pamberi pe2G. MuMalaysia, semuenzaniso, vese vashandisi vakavhara 3G network yavo pasi pekutariswa nehurumende.
MuIndonesia, vaviri vevatatu vanoshanda vakavhara 3G network uye chirongwa chechitatu chekuita kudaro (ikozvino, hapana mumwe wevatatu ane zvirongwa zvekuvhara 2G network).
· Africa inoramba ichivimba ne2G network
MuAfrica, 2G yakapetwa kaviri saizi ye3G. Feature mafoni achiri account ye42% yehuwandu, uye mutengo wavo wakaderera unokurudzira vashandisi vekupedzisira kuti varambe vachishandisa zvishandiso izvi. Izvi, zvakare, zvakakonzera kuderera kwe smartphone kupinda, saka zvirongwa zvishoma zvakaziviswa kudzosera kumashure Internet mudunhu.
