Yakatangwa zviri pamutemo muna 1991, network dze2G dzine mafoni nemeseji chete, uye tekinoroji iyi yasara kumashure zvikuru kune network dze4G/5G dziri kushandiswa zvakanyanya nhasi. Kubva munaGunyana, vashandi 142 munyika makumi mashanu nematanhatu vakanga vapedza, vakaronga kana kuti vari mubishi rekudzima network dzavo dze2G/3G, zvichienderana nedata rakaburitswa neGlobal Mobile Providers Association.
2G/3G inodhura zvakanyanya uye inotora zviwanikwa zve spectrum zvinoparadza.
Nekusvika kwe5G, vashandi vemuno vanosangana ne2G, 3G, 4G, 5G "zvizvarwa zvina", asi izvi hazvisi mufaro, asi kurwadziwa nekumanikidzwa, mari yekushandisa nekugadzirisa inoramba yakakwira, zviwanikwa zvakawanda hazvina kukwana, zviwanikwa zvepaindaneti hazvina kukwana, zvichikanganisa zvakanyanya kukura kweindasitiri yeruzivo nekutaurirana muChina.
Nekufambira mberi kwesainzi netekinoroji uye kuvandudzwa kuri kuramba kuchiitwa kwezvinodiwa nevanhu pakutaurirana, kumhanya kwekutaurirana uye masevhisi anopihwa netekinoroji ye2G ne3G hazvina kukwanisa kusangana nezvinodiwa nevanhu. Zviwanikwa zvespectrum zvinogara mutekinoroji ye2G ne3G zvakaganhurirwawo, uye kana tikaramba tichishandisa matekinoroji e2G ne3G, tichatambisa zviwanikwa zvakawanda zvespectrum.
Mamiriro ezvinhu e2G ne3G muChina: vashandisi vakawanda, uye kukurumidza kubvisa mari kuri kunonoka
Huwandu hwevanhu vanoshandisa 2G muChina hwakakura zvikuru. Zvichienderana nedata rakaburitswa neBazi reIndasitiri neTekinoroji yeRuzivo, kusvika muna 2020, pachava nevanhu vanoshandisa 2G mamiriyoni 273 panetwork, zvichireva 17.15% yevashandisi vese. Vazhinji vevanhu ava vakwegura vari munzvimbo dziri kure, vasingade mafoni akawanda uye vanofona zvakanyanya.
Ling Li, purofesa wepachikoro cheSainzi yeRuzivo neUinjiniya paFudan University, akati kuvandudzwa kwetekinoroji ndiyo nzira yakajairika, uye vanoshanda vari "kusiya" network dze2G/3G, asi maitiro acho haasi ekubudirira kamwe chete, nekuti kuchine vashandisi vazhinji vanoshandisa network dze2G kana 3G. Pamusoro pezvo, pamusoro pekufona, kune imwe application isingafaniri kufuratirwa, kureva kuti, sisitimu yeInternet of Things inoshandiswa mukutarisira guta, mimwe yemidziyo iyi iri kushandisawo network dze2G/3G kutaurirana.
Nharembozha yevakuru inogona kuramba ichishandiswa here?
Vashandi vemunharaunda muGuangzhou China vakapindura kuti network dze2G hadzisipo uye mabasa eVoLTE aifanira kuvhurwa panharembozha. VoLTE ibasa rekufona rakavakirwa panetwork dze4G, uye kana usina chinhu ichi pafoni yako, hauzokwanisi kuramba uchichishandisa uye uchafanira kutenga foni itsva. Parizvino, kusimudzira SIM card ye2G mobile kuita SIM card ye4G kana 5G mobile SIM kwakasununguka uye hapana chikonzero chekuchinja hurongwa.
