I-2G I-3G ikhutshwa kancinci kancinci kwinethiwekhi, ngaba ifowuni ephathwayo yabantu abadala ingasetyenziswa?

Yaqaliswa ngokusemthethweni ngo-1991, iinethiwekhi ze-2G zineefowuni zelizwi kunye nemiyalezo ebhaliweyo kuphela, kwaye ubuchwepheshe buye basemva kakhulu kwiinethiwekhi ze-4G/5G ezisetyenziswa kakhulu namhlanje. Ukusukela ngoSeptemba, abaqhubi abali-142 kumazwe angama-56 babegqibile, becwangcise okanye bekwinkqubo yokuvala iinethiwekhi zabo ze-2G/3G, ngokutsho kwedatha ekhutshwe yi-Global Mobile Providers Association.

I-2G/3G ineendleko eziphezulu zokusebenza kwaye ithatha izixhobo ze-spectrum ezichitha imali eninzi.

Ngokufika kwe-5G, abaqhubi basekhaya badibana ne-2G, 3G, 4G, 5G “izizukulwana ezine”, kodwa oku akuyonto yolonwabo, kodwa intlungu kunye noxinzelelo, iindleko zokusebenza kunye nokugcinwa zihlala ziphezulu, izixhobo ze-spectrum zinqongophele, izixhobo zesiza azanelanga, nto leyo echaphazela kakhulu uphuhliso lweshishini lolwazi nonxibelelwano laseTshayina.

Ngenxa yenkqubela phambili yesayensi netekhnoloji kunye nokuphuculwa okuqhubekayo kweemfuno zabantu kwiinethiwekhi zonxibelelwano, isantya sonxibelelwano kunye neenkonzo ezibonelelwa ziiteknoloji ze-2G kunye ne-3G azikwazanga ukuhlangabezana neemfuno zabantu. Izixhobo ze-spectrum ezihlala kwiiteknoloji ze-2G kunye ne-3G nazo zinqongophele, kwaye ukuba siqhubeka nokusebenzisa iiteknoloji ze-2G kunye ne-3G, siza kuchitha izixhobo ezininzi ze-spectrum.

Imeko ye-2G kunye ne-3G eTshayina: abasebenzisi baninzi, kwaye isantya sokurhoxisa sicotha

Inani labasebenzisi be-2G eTshayina likhulu kakhulu. Ngokwedatha ekhutshwe yiSebe lezoShishino kunye neTekhnoloji yoLwazi, ukusukela ngo-2020, kuza kubakho abasebenzisi be-2G abazizigidi ezingama-273 kwinethiwekhi, nto leyo ethetha i-17.15% yabo bonke abasebenzisi. Uninzi lwaba bantu ngabantu abadala kwiindawo ezikude, abaswele kakhulu iifowuni eziphathwayo kwaye ikakhulu benza iifowuni.

ULing Li, uprofesa oncedisayo kwiSikolo seSayensi yoLwazi kunye noBunjineli kwiYunivesithi yaseFudan, uthe ukuhlaziywa kwetekhnoloji yindlela eqhelekileyo, kwaye abaqhubi nabo "bayahlukana" neenethiwekhi ze-2G/3G, kodwa le nkqubo ayiphumeleli ngobusuku obunye, kuba kusekho abasebenzisi abaninzi abasebenzisa iinethiwekhi ze-2G okanye ze-3G. Ukongeza, ukongeza kwiifowuni, kukho esinye isicelo esingenakutyeshelwa, oko kukuthi, inkqubo ye-Intanethi yezinto esetyenziswa kulawulo lwesixeko, ezinye zezi zixhobo zisebenzisa neenethiwekhi ze-2G/3G ukunxibelelana.

Ngaba ifowuni ephathwayo yabantu abadala ingaqhubeka nokusetyenziswa?

Abaqhubi basekuhlaleni eGuangzhou, eTshayina, baphendule bathi iinethiwekhi ze-2G aziyi kufumaneka kwaye imisebenzi ye-VoLTE kuya kufuneka ivulwe kwiifowuni eziphathwayo. I-VoLTE yinkonzo yokufowuna esekelwe kwiinethiwekhi ze-4G, kwaye ukuba awunalo olu phawu kwifowuni yakho, awuyi kukwazi ukuqhubeka ulusebenzisa kwaye kuya kufuneka uthenge ifowuni entsha. Okwangoku, ukuphucula ikhadi le-SIM eliphathwayo le-2G libe yikhadi le-SIM eliphathwayo le-4G okanye le-5G kusimahla kwaye akukho mfuneko yokutshintsha isicwangciso.
