Yakatangwa zviri pamutemo muna 1991, 2G network inoratidzira chete mafoni ezwi uye mameseji, uye tekinoroji yakasarira kumashure kwe4G/5G network ari kushandiswa zvakanyanya nhasi. Kubva munaSeptember, vashandi ve142 munyika dze56 vakanga vapedza, vakaronga kana kuti vakanga vari mukugadzirisa kuvhara 2G / 3G network, maererano nemashoko akabudiswa neGlobal Mobile Providers Association.
2G/3G ine mutengo wakakwira wekushandisa uye inopambadza zviwanikwa
Nekusvika kwe5G, vashandi vepamba vanosangana ne2G, 3G, 4G, 5G "zvizvarwa zvina", asi izvi hazvisi mufaro, asi kurwadziwa uye kumanikidzwa, kushanda uye kugadzirisa mari inoramba ichikwira, zviwanikwa zve spectrum zvishoma, zviwanikwa zvesaiti hazvina kukwana, zvakakomba. inokanganisa kuvandudzwa kweindasitiri yeruzivo nekutaurirana.
Nekufambira mberi kwesainzi uye tekinoroji uye nekuvandudzika kunoenderera mberi kwezvinodiwa nevanhu pamanetiweki ekutaurirana, kukurumidza kwekutaurirana nemasevhisi anopihwa ne2G uye 3G tekinoroji zvatadza kuzadzisa zvinodiwa nevanhu. Iyo spectrum zviwanikwa zvinogarwa ne 2G uye 3G tekinoroji zvakare ishoma, uye kana tikaramba tichishandisa 2G uye 3G tekinoroji, isu tichaparadza yakawanda spectrum zviwanikwa.
Mamiriro e2G uye 3G muChina: base base yakakura, uye nhanho yekubvisa inononoka.
Nhamba yevashandisi ve2G muChina yakakura kwazvo. Zvinoenderana nedata rakaburitswa neBazi reIndasitiri uye Ruzivo rweTekinoroji, kubva muna 2020, kuchave ne273 miriyoni 273 vashandisi ve2G pane network, inoverengera 17.15% yevashandisi vese. Vazhinji vevanhu ava vanhu vakura vari kunzvimbo dziri kure, vasingade mafoni emhando yepamusoro uye vanonyanya kufona.
Ling Li, purofesa anobatana paChikoro cheRuzivo rweSainzi neUinjiniya paFudan University, akataura kuti tekinoroji iteration ndiyo yakajairika, uye vashandisi vari "kubvarura" kune 2G / 3G network, asi maitiro haasi kubudirira kwehusiku humwe. nekuti pachine vashandisi vakawanda vanoshandisa 2G kana 3G network. Uye zvakare, kunze kwekufona, pane imwe application isingagone kufuratirwa, iyo iyo Internet yeZvinhu system inoshandiswa mukutonga kweguta, zvimwe zvezvishandiso izvi zviri kushandisawo 2G/3G network kutaurirana.
Serura dzevakwegura dzinogona kuramba dzichishandiswa here?
Vashandi vemunharaunda muGuangzhou China vakapindura kuti 2G network yaisazovepo uye mabasa eVoLTE aizoda kugoneswa panharembozha. VoLTE ibasa rekufona rakavakirwa pamanetiweki e4G, uye kana usina chinhu ichi pafoni yako, haugone kuenderera mberi nekuishandisa uye uchada kutenga foni nyowani. Parizvino, kusimudzira 2G mobile SIM card kune 4G kana 5G mobile SIM card ndeye mahara uye hapana chikonzero chekuchinja chirongwa.
