Iqaliswe ngokusemthethweni kwi-1991, iinethiwekhi ze-2G zibonakalisa kuphela iifowuni zezwi kunye nemiyalezo, kwaye iteknoloji iye yasala emva kweenethiwekhi ze-4G / 5G ezisetyenziswa ngokubanzi namhlanje.Ukususela ngoSeptemba, abaqhubi be-142 kumazwe e-56 baye bagqiba, bacetywayo okanye bakwinkqubo yokuvala amanethiwekhi abo e-2G / 3G, ngokwedatha ekhutshwe yi-Global Mobile Providers Association.
I-2G / 3G ineendleko eziphezulu zokusebenza kwaye ithatha imithombo ye-spectrum echithwayo
Ngokufika kwe-5G, abaqhubi basekhaya badibana ne-2G, i-3G, i-4G, i-5G "izizukulwana ezine", kodwa oku akusiyo ulonwabo, kodwa intlungu kunye noxinzelelo, iindleko zokusebenza kunye nokugcinwa kweendleko zihlala ziphezulu, izibonelelo ze-spectrum zilinganiselwe, izixhobo zesayithi azanelanga, ngokunzulu. echaphazela uphuhliso lweshishini lolwazi kunye nonxibelelwano lwaseTshayina.
Ngenkqubela phambili yenzululwazi kunye nobuchwepheshe kunye nokuphuculwa okuqhubekayo kweemfuno zabantu kuthungelwano lonxibelelwano, isantya sonxibelelwano kunye neenkonzo ezinikezelwa yi-2G kunye ne-3G teknoloji azikwazanga ukuhlangabezana neemfuno zabantu.Izixhobo ze-spectrum ezithathwe yi-2G kunye ne-3G teknoloji nazo zilinganiselwe, kwaye ukuba siqhubeka sisebenzisa i-2G kunye ne-3G iteknoloji, siya kulahla izibonelelo ezininzi ze-spectrum.
Imeko ye-2G kunye ne-3G e-China: isiseko somsebenzisi sikhulu, kwaye isantya sokuhoxiswa siyacotha
Inani labasebenzisi be-2G e-China likhulu kakhulu.Ngokutsho kwedatha ekhutshwe nguMphathiswa wezoShishino kunye neTekhnoloji yoLwazi, ukususela ngo-2020, kuya kubakho abasebenzisi be-273 yezigidi ze-2G kuthungelwano, kubalwa i-17.15% yabasebenzisi bebonke.Uninzi lwaba bantu ngabantu abasele bekhulile abakwiindawo ezikude, abanemfuno encinci yeefowuni ze-smart kwaye ubukhulu becala bafowunela.
U-Ling Li, uprofesa odibeneyo kwiSikolo soLwazi lweNzululwazi kunye nobuNjineli kwiYunivesithi yaseFudan, uthe ukuphindaphinda kweteknoloji yindlela eqhelekileyo, kwaye abaqhubi nabo "baqhekeza" kwiinethiwekhi ze-2G / 3G, kodwa inkqubo ayikho impumelelo yobusuku. kuba kusekho abasebenzisi abaninzi abasebenzisa iinethiwekhi ze-2G okanye ze-3G.Ukongeza, ukongeza kwiifowuni zeefowuni, kukho esinye isicelo esingenako ukungahoywa, oko kukuthi, inkqubo ye-Intanethi yezinto ezisetyenziswa kulawulo lwesixeko, ezinye zezi zixhobo zisebenzisa i-2G/3G networks ukunxibelelana.
Ngaba iiselfowuni zabantu abadala zinokuqhubeka zisetyenziswa?
Abaqhubi bendawo e-Guangzhou China baphendule ukuba uthungelwano lwe-2G aluyi kufumaneka kwaye imisebenzi ye-VoLTE iya kufuneka ivulwe kwiifowuni eziphathwayo.I-VoLTE yinkonzo yokufowuna esekwe kwiinethiwekhi ze-4G, kwaye ukuba awunalo eli nqaku kwifowuni yakho, awuyi kukwazi ukuqhubeka nokuyisebenzisa kwaye kuya kufuneka uthenge ifowuni entsha.Okwangoku, ukuphuculwa kwe-SIM khadi ye-2G yeselula kwi-4G okanye i-5G ye-SIM khadi yeselula ikhululekile kwaye akukho mfuneko yokutshintsha isicwangciso.
