2G 3G imachotsedwa pang'onopang'ono pa intaneti, kodi foni yam'manja ya okalamba ingagwiritsidwe ntchito?

Zinakhazikitsidwa mwalamulo mu 1991, maukonde a 2G amangokhala ndi mafoni ndi mameseji okha, ndipo ukadaulo watsalira kwambiri pamanetiweki a 4G/5G omwe amagwiritsidwa ntchito kwambiri masiku ano. Kuyambira mwezi wa September, ogwira ntchito a 142 m'mayiko a 56 anali atamaliza, anakonza kapena anali kutseka ma network awo a 2G / 3G, malinga ndi deta yomwe inatulutsidwa ndi Global Mobile Providers Association.

2G/3G ili ndi ndalama zambiri zogwirira ntchito ndipo imagwiritsa ntchito zinthu zowonongeka

Ndi kufika kwa 5G, ogwira ntchito zapakhomo amakumana ndi 2G, 3G, 4G, 5G "mibadwo inayi", koma izi siziri chisangalalo, koma ululu ndi kupanikizika, ntchito ndi kukonza ndalama zimakhalabe zapamwamba, zida zowonongeka zimakhala zochepa, malo osungira malo sali okwanira, mozama. zomwe zikukhudza chitukuko cha makampani achidziwitso ndi kulumikizana ku China.

Ndi kupita patsogolo kwa sayansi ndi luso lamakono komanso kusintha kosalekeza kwa zofuna za anthu pa maukonde olankhulana, liwiro la kulankhulana ndi ntchito zoperekedwa ndi teknoloji ya 2G ndi 3G zalephera kukwaniritsa zosowa za anthu. Zomwe zimagwiritsidwa ntchito ndi teknoloji ya 2G ndi 3G ndizochepa, ndipo ngati tipitiriza kugwiritsa ntchito teknoloji ya 2G ndi 3G, tidzawononga zinthu zambiri.

Mkhalidwe wa 2G ndi 3G ku China: malo ogwiritsira ntchito ndi aakulu, ndipo kuthamanga kwa kuchoka kumachedwa

Chiwerengero cha ogwiritsa ntchito 2G ku China ndi chachikulu kwambiri. Malinga ndi zomwe zatulutsidwa ndi Unduna wa Zamakampani ndi Zaukadaulo Zaukadaulo, pofika chaka cha 2020, pakhala ogwiritsa ntchito 273 miliyoni a 2G pamanetiweki, omwe ndi 17.15% ya ogwiritsa ntchito onse. Ambiri mwa anthuwa ndi okalamba omwe amakhala kumadera akumidzi, omwe safuna kwambiri mafoni anzeru ndipo makamaka amaimba mafoni.

Ling Li, pulofesa wothandizira pa School of Information Science and Engineering ku Fudan University, adanena kuti teknoloji iteration ndiyomwe ikuchitika, ndipo ogwira ntchito nawonso "akuswa" chifukwa cha maukonde a 2G / 3G, koma ndondomekoyi sipambana usiku wonse. chifukwa pali ogwiritsa ntchito ambiri omwe amagwiritsa ntchito maukonde a 2G kapena 3G. Kuphatikiza apo, kuwonjezera pa kuyimba foni, palinso ntchito ina yomwe singanyalanyazidwe, ndiko kuti, intaneti ya Zinthu zomwe zimagwiritsidwa ntchito poyang'anira mizinda, zina mwa zidazi zikugwiritsanso ntchito maukonde a 2G/3G kuti azilumikizana.

Kodi mafoni a m'manja a okalamba angapitirizebe kugwiritsidwa ntchito?

Ogwiritsa ntchito am'deralo ku Guangzhou China adayankha kuti ma netiweki a 2G sadzakhalapo ndipo ntchito za VoLTE ziyenera kuyatsidwa pamafoni am'manja. VoLTE ndi ntchito yoyimba foni yozikidwa pamanetiweki a 4G, ndipo ngati mulibe izi pafoni yanu, simungathe kupitiliza kuigwiritsa ntchito ndipo muyenera kugula foni yatsopano. Pakalipano, kukweza SIM khadi ya 2G ku 4G kapena 5G SIM khadi yam'manja ndi yaulere ndipo palibe chifukwa chosinthira dongosolo.
