Tau tsim tawm xyoo 1991, 2G tes hauj lwm tsuas yog muaj kev hu xov tooj thiab cov lus ntawv xwb, thiab cov thev naus laus zis tau poob qis dua 4G/5G tes hauj lwm uas siv dav niaj hnub no. Txij li lub Cuaj Hli, 142 tus neeg teb xov tooj hauv 56 lub teb chaws tau ua tiav, npaj lossis tab tom kaw lawv cov tes hauj lwm 2G/3G, raws li cov ntaub ntawv tso tawm los ntawm Global Mobile Providers Association.
2G/3G muaj cov nqi khiav lag luam siab thiab siv cov peev txheej spectrum pov tseg.
Nrog rau kev tuaj txog ntawm 5G, cov neeg ua haujlwm hauv tsev ntsib 2G, 3G, 4G, 5G "plaub tiam neeg", tab sis qhov no tsis yog kev zoo siab, tab sis kev mob thiab kev nyuaj siab, kev ua haujlwm thiab kev saib xyuas cov nqi tseem siab, cov peev txheej spectrum tsawg, cov peev txheej ntawm qhov chaw tsis txaus, cuam tshuam loj heev rau kev txhim kho ntawm Tuam Tshoj cov ntaub ntawv thiab kev sib txuas lus.
Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho tas mus li ntawm cov neeg xav tau kev sib txuas lus, qhov ceev ntawm kev sib txuas lus thiab cov kev pabcuam uas 2G thiab 3G thev naus laus zis muab tsis tau raws li cov neeg xav tau. Cov peev txheej spectrum uas 2G thiab 3G thev naus laus zis siv kuj tsawg, thiab yog tias peb txuas ntxiv siv 2G thiab 3G thev naus laus zis, peb yuav pov tseg ntau cov peev txheej spectrum.
Qhov xwm txheej ntawm 2G thiab 3G hauv Suav teb: cov neeg siv khoom loj heev, thiab qhov nrawm ntawm kev rho tawm qeeb
Tus naj npawb ntawm cov neeg siv 2G hauv Suav teb yog loj heev. Raws li cov ntaub ntawv tso tawm los ntawm Ministry of Industry thiab Information Technology, txij li xyoo 2020, yuav muaj 273 lab tus neeg siv 2G hauv lub network, suav txog 17.15% ntawm tag nrho cov neeg siv. Ntau tus ntawm cov neeg no yog cov neeg laus nyob rau thaj chaw deb, uas muaj kev xav tau tsawg dua rau cov xov tooj ntse thiab feem ntau yog hu xov tooj.
Ling Li, ib tug xibfwb qhia ntawv ntawm Tsev Kawm Ntawv Qhia Txog Kev Tshawb Fawb thiab Kev Tsim Kho ntawm Fudan University, tau hais tias kev siv thev naus laus zis yog qhov sib txawv, thiab cov neeg teb xov tooj kuj "tso tseg" rau 2G / 3G tes hauj lwm, tab sis cov txheej txheem tsis yog kev vam meej ib hmos, vim tias tseem muaj ntau tus neeg siv siv 2G lossis 3G tes hauj lwm. Tsis tas li ntawd, ntxiv rau kev hu xov tooj, muaj lwm daim ntawv thov uas tsis tuaj yeem tsis quav ntsej, uas yog, Internet of Things system siv hauv kev tswj hwm nroog, qee qhov ntawm cov khoom siv no kuj siv 2G / 3G tes hauj lwm los sib txuas lus.
Puas siv tau lub xov tooj ntawm tes rau cov neeg laus?
Cov neeg teb xov tooj hauv zos hauv Guangzhou Suav teb tau teb tias 2G network yuav tsis muaj thiab VoLTE functions yuav tsum tau qhib rau ntawm cov xov tooj ntawm tes. VoLTE yog ib qho kev pabcuam hu xov tooj raws li 4G networks, thiab yog tias koj tsis muaj qhov feature no ntawm koj lub xov tooj, koj yuav tsis tuaj yeem siv nws ntxiv thiab yuav tsum tau yuav lub xov tooj tshiab. Tam sim no, kev hloov kho daim npav SIM mobile 2G mus rau daim npav SIM mobile 4G lossis 5G yog pub dawb thiab tsis tas yuav hloov txoj kev npaj.
