2G 3G ikuchotsedwa pang'onopang'ono pa netiweki, kodi foni yam'manja ya okalamba ingagwiritsidwebe ntchito?

Ma network a 2G omwe adayambitsidwa mwalamulo mu 1991, amakhala ndi mafoni ndi mauthenga a pafoni okha, ndipo ukadaulowu watsala pang'ono kutha ndi ma network a 4G/5G omwe amagwiritsidwa ntchito kwambiri masiku ano. Pofika mu Seputembala, ogwira ntchito 142 m'maiko 56 anali atamaliza, kukonzekera kapena anali mkati motseka ma network awo a 2G/3G, malinga ndi deta yomwe idatulutsidwa ndi Global Mobile Providers Association.

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

Pamene 5G yafika, ogwira ntchito m'nyumba akukumana ndi 2G, 3G, 4G, 5G "mibadwo inayi", koma izi si chimwemwe, koma ululu ndi kupsinjika, ndalama zogwirira ntchito ndi kukonza zikupitirirabe kukhala zapamwamba, zinthu zogwiritsidwa ntchito ndi anthu ambiri ndizochepa, zinthu zomwe zili pamalopo sizokwanira, zomwe zikukhudza kwambiri chitukuko cha makampani olankhulana ndi chidziwitso ku China.

Chifukwa cha kupita patsogolo kwa sayansi ndi ukadaulo komanso kupititsa patsogolo zosowa za anthu pa maukonde olumikizirana, liwiro la kulumikizana ndi ntchito zomwe ukadaulo wa 2G ndi 3G umapereka sizikukwaniritsa zosowa za anthu. Zinthu zomwe zimagwiritsidwa ntchito ndi ukadaulo wa 2G ndi 3G nazonso ndi zochepa, ndipo ngati tipitiliza kugwiritsa ntchito ukadaulo wa 2G ndi 3G, tidzawononga zinthu zambiri zomwe zimagwiritsidwa ntchito.

Mkhalidwe wa 2G ndi 3G ku China: ogwiritsa ntchito ndi ambiri, ndipo liwiro lochotsa ntchito ndi lochepa

Chiwerengero cha ogwiritsa ntchito 2G ku China ndi chachikulu kwambiri. Malinga ndi deta yomwe yatulutsidwa ndi Unduna wa Zamalonda ndi Ukadaulo wa Chidziwitso, pofika chaka cha 2020, padzakhala ogwiritsa ntchito 2G okwana 273 miliyoni pa netiwekiyi, zomwe zikuyimira 17.15% ya ogwiritsa ntchito onse. Ambiri mwa anthuwa ndi okalamba omwe ali m'madera akutali, omwe sakufuna mafoni anzeru ambiri ndipo nthawi zambiri amaimba mafoni.

Ling Li, pulofesa wothandizira pa Sukulu ya Sayansi ndi Uinjiniya ku Fudan University, anati kusintha kwa ukadaulo ndi njira yodziwika bwino, ndipo ogwiritsa ntchito "akusiya" maukonde a 2G/3G, koma njirayi si yopambana mwadzidzidzi, chifukwa pakadali ogwiritsa ntchito ambiri omwe amagwiritsa ntchito maukonde a 2G kapena 3G. Kuphatikiza apo, kuwonjezera pa kuyimba foni, pali pulogalamu ina yomwe singanyalanyazidwe, ndiko kuti, makina a Internet of Things omwe amagwiritsidwa ntchito poyang'anira mzinda, zina mwa zidazi zikugwiritsanso ntchito maukonde a 2G/3G polankhulana.

Kodi foni yam'manja ya okalamba ingapitirire kugwiritsidwa ntchito?

Ogwira ntchito m'deralo ku Guangzhou China adayankha kuti ma netiweki a 2G sangapezeke ndipo ntchito za VoLTE ziyenera kuyatsidwa pa mafoni am'manja. VoLTE ndi ntchito yoimbira foni yozikidwa pa ma netiweki a 4G, ndipo ngati mulibe izi pafoni yanu, simudzatha kupitiliza kuzigwiritsa ntchito ndipo mudzafunika kugula foni yatsopano. Pakadali pano, kukweza SIM khadi ya 2G kukhala SIM khadi ya 4G kapena 5G ndi kwaulere ndipo palibe chifukwa chosinthira dongosololi.
