Nekushandiswa kwema network e4G ne5G, kushanda kwe 2G ne 3G pasina internet munyika dzakawanda nenzvimbo dziri kufambira mberi zvishoma nezvishoma. Chinyorwa chino chinopa ruzivo rwemaitiro e 2G ne 3G asina internet pasi rese.
Sezvo network dze5G dzichiri kuenderera mberi pasi rose, 2G ne3G dziri kusvika pakupera. Kudzikiswa kwe2G ne3G kuchakanganisa kushandiswa kweiot uchishandisa matekinoroji aya. Pano, tichakurukura nyaya dzinofanirwa kutariswa nemabhizinesi panguva yekushanda kwe2G/3G pasina internet uye matanho ekudzivirira.
Kukanganiswa kwe2G ne3G pasina internet pakubatana kweIOT uye nzira dzekudzivisa
Sezvo 4G ne5G zviri kushandiswa pasi rose, kushanda kwe2G ne3G pasina internet munyika dzakawanda nenzvimbo dziri kufambira mberi zvishoma nezvishoma. Maitiro ekudzima network anosiyana kubva munyika kuenda kunyika, kungave zvichienderana nesarudzo dzevatongi vemunharaunda kuti vasunungure zviwanikwa zvinokosha zve spectrum, kana kuti zvichienderana nesarudzo dzevashandi venharembozha kuti vadzime network kana masevhisi aripo asingakonzeri kuti arambe achishanda.
Manetwork e2G, ayo ave achiwanikwa mukutengeserana kwemakore anopfuura makumi matatu, anopa puratifomu yakanaka yekuisa mhinduro dzemhando yepamusoro dzeiot munyika yese nepasi rose. Kugara kwenguva refu kwemhinduro dzakawanda dzeiot, kazhinji dzinopfuura makore gumi, zvinoreva kuti kuchine nhamba yakakura yemidziyo inogona kushandisa network dze2G chete. Nekuda kweizvozvo, matanho anofanirwa kutorwa kuona kuti mhinduro dzeiot dzinoramba dzichishanda kana 2G ne3G dzisiri kushanda.
Kudzikiswa kwe2G ne3G kwakatangwa kana kuti kwapera mune dzimwe nyika, dzakadai seUS neAustralia. Mazuva acho akasiyana-siyana kune dzimwe nzvimbo, uye nzvimbo zhinji dzeEurope dzakagadzirira kupera kwegore ra2025. Nekufamba kwenguva, network dze2G ne3G dzichazobuda mumusika zvachose, saka iri idambudziko risingadzivisiki.
Maitiro ekubvisa 2G/3G anosiyana kubva panzvimbo nenzvimbo, zvichienderana nehunhu hwemusika wega wega. Nyika dzakawanda nenzvimbo dzakawanda dzazivisa zvirongwa zve2G ne3G offline. Huwandu hwenetwork dzakavharirwa hucharamba huchiwedzera. Manetwork anopfuura 55 e2G ne3G anotarisirwa kuvharwa pakati pa2021 na2025, zvichienderana nedata reGSMA Intelligence, asi matekinoroji maviri aya haazombomiswa panguva imwe chete. Mune mimwe misika, 2G inotarisirwa kuramba ichishanda kwemakore gumi kana kupfuura, sezvo masevhisi chaiwo akadai sekubhadhara nefoni muAfrica uye masisitimu ekufona nekukurumidza kwemotokari (eCall) mune mimwe misika achivimba nemanetwork e2G. Muzviitiko izvi, manetwork e2G anogona kuramba achishanda kwenguva yakareba.
3G ichasiya musika riini?
Kubviswa kwema network e3G kwagara kwakarongwa kwemakore uye kwakadzimwa munyika dzinoverengeka. Misika iyi yave ne4G yakawanda uye iri pamberi pehuwandu hwe5G, saka zvine musoro kudzima network dze3G uye kuisa spectrum kune tekinoroji yechizvarwa chinotevera.
Kusvika pari zvino, network dzakawanda dze3G dzakavharwa muEurope kupfuura 2G, uye mumwe chete muDenmark akavhara network yake ye3G muna 2015. Sekureva kweGSMA Intelligence, vashandi gumi nevapfumbamwe munyika gumi nemana dzemuEurope vanoronga kuvhara network dzavo dze3G panosvika gore ra2025, ukuwo vasere chete munyika sere vachironga kuvhara network dzavo dze2G panguva imwe chete. Huwandu hwekuvharwa kwenetwork huri kuwedzera sezvo vatakuri vachizivisa zvirongwa zvavo. Kuvharwa kwenetwork ye3G muEurope Mushure mekuronga zvakanaka, vashandi vazhinji vakazivisa mazuva avo ekuvharwa kwe3G. Imwe nzira itsva iri kubuda muEurope ndeyekuti vamwe vashandi vari kuwedzera nguva yakarongwa yekushanda ye2G. Semuenzaniso, muUK, ruzivo rwazvino rwunoratidza kuti zuva rakarongwa rekutanga ra2025 rakadzoserwa shure nekuti hurumende yaita chibvumirano nevanoshanda nefoni kuti network dze2G dzirambe dzichishanda kwemakore mashoma anotevera.
· Manetwork e3G ekuAmerica akavharwa
Kuvharwa kwenetwork ye3G muUnited States kuri kufambira mberi zvakanaka nekushandiswa kwemanetwork e4G ne5G, uye macarrier ese makuru anotarisira kupedzisa kuburitswa kwe3G panosvika kupera kwa2022. Mumakore apfuura, dunhu reAmerica raive rakatarisa pakuderedza saizi ye2G sezvo macarrier akatanga kuburitsa 5G. Vanoshanda vari kushandisa spectrum yakasunungurwa nekuburitswa kwe2G kuti vagadzirise kudiwa kwemanetwork e4G ne5G.
· Manetwork e2G eAsia avhara maitiro
Vanopa masevhisi muAsia vari kuchengetedza ma network e3G ukuwo vachivhara ma network e2G kuti vatumire spectrum kune ma network e4G, ayo anoshandiswa zvakanyanya munharaunda iyi. Pakupera kwegore ra2025, GSMA Intelligence inotarisira kuti vashandi makumi maviri nevapfumbamwe vadzime ma network avo e2G uye gumi nematanhatu vadzime ma network avo e3G. Dunhu rega muAsia rakavhara ma network ayo e2G (2017) ne3G (2018) iTaiwan.
MuAsia, kune zvimwe zvisingaitwe: vashandi vakatanga kudzikisa huwandu hwe3G 2G isati yasvika. Semuenzaniso, muMalaysia, vese vashandi vakavhara network dzavo dze3G vachitarisirwa nehurumende.
MuIndonesia, vaviri vevatatu ava vakavhara network dzavo dze3G uye wechitatu akaronga kuzviita (parizvino, hapana kana mumwe wavo ane hurongwa hwekudzima network dzavo dze2G).
· Africa inoramba ichivimba ne2G network
MuAfrica, 2G yakakura kaviri pane 3G. Mafoni ane hunyanzvi achiri kuita 42% yehuwandu hwese, uye mutengo wakaderera unokurudzira vashandisi kuti varambe vachishandisa zvishandiso izvi. Izvi zvakakonzera kuti mafoni apinde mashoma, saka zvirongwa zvishoma zvakaziviswa zvekudzosera internet munharaunda iyi.
