I whakarewaina mana i te tau 1991, ko ngā whatunga 2G he waea reo me ngā karere kuputuhi anake, ā, kua roa te hangarau e whai muri ana i ngā whatunga 4G/5G e whakamahia whānuitia ana i ēnei rā. I te marama o Hepetema, 142 ngā kaiwhakahaere i roto i te 56 whenua kua oti, kua whakamahere, kua tata rānei te kati i ā rātou whatunga 2G/3G, e ai ki ngā raraunga i tukuna e te Global Mobile Providers Association.
He nui ngā utu whakahaere o te 2G/3G, ā, he maumau rauemi mō te whānuitanga o te irahiko e pau ana.
I te taenga mai o te 5G, ka tūtaki ngā kaiwhakahaere o te whare ki te 2G, 3G, 4G, 5G mō ngā "whakatipuranga e whā", engari ehara tēnei i te harikoa, engari he mamae me te pēhanga, kei te teitei tonu ngā utu whakahaere me te tiaki, he iti ngā rauemi mō te whānuitanga o te hihi, he koretake ngā rauemi o te pae tukutuku, ā, he tino pā ki te whanaketanga o te umanga mōhiohio me te whakawhitiwhiti kōrero o Haina.
I te whanaketanga o te pūtaiao me te hangarau, me te whakapai tonu i ngā hiahia o te tangata mō ngā whatunga whakawhitiwhiti kōrero, kāore i taea e te tere whakawhitiwhiti kōrero me ngā ratonga e whakaratohia ana e ngā hangarau 2G me te 3G te whakatutuki i ngā hiahia o te tangata. He iti hoki ngā rauemi auhiko e whakamahia ana e ngā hangarau 2G me te 3G, ā, ki te whakamahi tonu tātou i ngā hangarau 2G me te 3G, ka moumouhia e tātou he nui ngā rauemi auhiko.
Te āhua o te 2G me te 3G i Haina: he nui te turanga kaiwhakamahi, ā, he puhoi te tere o te tango
He tino nui te tokomaha o ngā kaiwhakamahi 2G i Haina. E ai ki ngā raraunga i tukuna e te Manatū Ahumahi me te Hangarau Mōhiohio, tae noa ki te tau 2020, ka eke ki te 273 miriona ngā kaiwhakamahi 2G i runga i te whatunga, arā, 17.15% o ngā kaiwhakamahi katoa. He tokomaha o ēnei tāngata he kaumātua kei ngā rohe tūmatanui, he iti ake te hiahia mō ngā waea atamai, ā, ko te nuinga o rātou he waea atu.
I kī a Ling Li, he ahorangi tuarua i te Kura Pūtaiao Mōhiohio me te Hangarau i Te Whare Wānanga o Fudan, ko te whakahoutanga hangarau te ia whānui, ā, kei te "wehe atu" hoki ngā kaiwhakahaere mō ngā whatunga 2G/3G, engari ehara i te mea he angitu tonu te tukanga, nā te mea he maha tonu ngā kaiwhakamahi e whakamahi ana i ngā whatunga 2G, 3G rānei. Hei tāpiri, hei tāpiri atu ki ngā waea, kei reira tētahi atu tono kāore e taea te wareware, arā, ko te pūnaha Ipurangi o ngā Mea e whakamahia ana i roto i te whakahaere tāone, ko ētahi o ēnei taputapu kei te whakamahi hoki i ngā whatunga 2G/3G hei whakawhitiwhiti kōrero.
Ka taea tonu te whakamahi i te waea pūkoro mō te hunga kaumātua?
I whakautu ngā kaiwhakahaere ā-rohe i Guangzhou Haina kāore e wātea ngā whatunga 2G, ā, me whakahohe ngā mahi VoLTE i runga i ngā waea pūkoro. He ratonga waea a VoLTE e hangai ana ki ngā whatunga 4G, ā, ki te kore tēnei āhuatanga i runga i tō waea, kāore e taea e koe te whakamahi tonu, ā, me hoko he waea hou. I tēnei wā, he kore utu te whakahou i tētahi kāri SIM pūkoro 2G ki tētahi kāri SIM pūkoro 4G, 5G rānei, ā, kāore he take ki te whakarerekē i te mahere.
