I-2G I-3G ikhishwa kancane kancane kunethiwekhi, ingabe ifoni ephathekayo yabantu abadala ingasetshenziswa?

Njengoba yasungulwa ngokusemthethweni ngo-1991, amanethiwekhi e-2G aqukethe izingcingo zezwi kanye nemiyalezo yombhalo kuphela, futhi ubuchwepheshe busilele emuva kakhulu kumanethiwekhi e-4G/5G asetshenziswa kabanzi namuhla. Kusukela ngoSepthemba, opharetha abangu-142 emazweni angu-56 base beqedile, behlele noma besenqubweni yokuvala amanethiwekhi abo e-2G/3G, ngokusho kwedatha ekhishwe yi-Global Mobile Providers Association.

I-2G/3G inezindleko zokusebenza eziphezulu futhi ithatha izinsizakusebenza ezichithayo ze-spectrum

Ngokufika kwe-5G, abaqhubi basekhaya bahlangabezana ne-2G, 3G, 4G, 5G “izizukulwane ezine”, kodwa lokhu akuyona injabulo, kodwa ubuhlungu kanye nengcindezi, izindleko zokusebenza kanye nokugcinwa zihlala ziphezulu, izinsizakusebenza zilinganiselwe, izinsizakusebenza zesayithi azanele, okuthinta kakhulu intuthuko yomkhakha wolwazi nokuxhumana waseShayina.

Ngokuthuthuka kwesayensi nobuchwepheshe kanye nokuthuthuka okuqhubekayo kwezidingo zabantu zamanethiwekhi okuxhumana, isivinini sokuxhumana kanye nezinsizakalo ezinikezwa ubuchwepheshe be-2G kanye ne-3G azikwazanga ukuhlangabezana nezidingo zabantu. Izinsizakusebenza ze-spectrum ezisetshenziswa ubuchwepheshe be-2G kanye ne-3G nazo zilinganiselwe, futhi uma siqhubeka nokusebenzisa ubuchwepheshe be-2G kanye ne-3G, sizochitha izinsizakusebenza eziningi ze-spectrum.

Isimo se-2G ne-3G eShayina: isisekelo sabasebenzisi sikhulu, futhi ijubane lokuhoxa lihamba kancane

Inani labasebenzisi be-2G eShayina likhulu kakhulu. Ngokusho kwedatha ekhishwe yi-Ministry of Industry and Information Technology, kusukela ngo-2020, kuzoba nabasebenzisi be-2G abayizigidi ezingu-273 kunethiwekhi, okubalwa u-17.15% wabo bonke abasebenzisi. Iningi lalaba bantu ngabantu asebekhulile ezindaweni ezikude, abanesidingo esincane samafoni ahlakaniphile futhi ikakhulukazi abashaya ucingo.

ULing Li, uprofesa ohlangene eSikoleni Sesayensi Yolwazi Nobunjiniyela eFudan University, uthe ukubuyekezwa kobuchwepheshe kuyindlela evamile, futhi abaqhubi nabo "bayahlukana" namanethiwekhi e-2G/3G, kodwa inqubo ayiphumeleli ngokushesha, ngoba kusenabasebenzisi abaningi abasebenzisa amanethiwekhi e-2G noma e-3G. Ngaphezu kwalokho, ngaphezu kwezingcingo, kukhona olunye uhlelo lokusebenza olungenakunakwa, okungukuthi, uhlelo lwe-Intanethi Yezinto olusetshenziswa ekuphathweni kwedolobha, amanye ala madivayisi nawo asebenzisa amanethiwekhi e-2G/3G ukuxhumana.

Ingabe ifoni ephathekayo yabantu abadala ingaqhubeka isetshenziswa?

Opharetha bendawo eGuangzhou, eShayina, baphendule ngokuthi amanethiwekhi e-2G ngeke atholakale futhi imisebenzi ye-VoLTE kuzodingeka ivulwe kumaselula. I-VoLTE iyisevisi yokushaya ucingo esekelwe kumanethiwekhi e-4G, futhi uma ungenalo lesi sici efonini yakho, ngeke ukwazi ukuqhubeka nokusisebenzisa futhi kuzodingeka uthenge ifoni entsha. Njengamanje, ukuthuthukisa ikhadi le-SIM leselula le-2G libe ikhadi le-SIM leselula le-4G noma le-5G kumahhala futhi asikho isidingo sokushintsha uhlelo.
