Hoʻokuʻu ʻia i ka makahiki 1991, ʻo nā pūnaewele 2G wale nō nā leo leo a me nā leka uila, a ua mamao loa ka ʻenehana ma hope o nā pūnaewele 4G/5G i hoʻohana nui ʻia i kēia mau lā.Ma ka mahina o Kepakemapa, ua hoʻopau, hoʻolālā ʻia a i ʻole ke hana ʻana o nā mea hana 142 ma 56 mau ʻāina i ka pani ʻana i kā lākou pūnaewele 2G/3G, e like me ka ʻikepili i hoʻokuʻu ʻia e ka Global Mobile Providers Association.
Loaʻa iā 2G/3G nā kumukūʻai hana kiʻekiʻe a paʻa i nā kumu waiwai kikoʻī
Me ka hōʻea ʻana mai o 5G, ʻike nā mea hoʻohana kūloko i ka 2G, 3G, 4G, 5G "ʻehā mau hanauna", akā ʻaʻole kēia he hauʻoli, akā ʻo ka ʻeha a me ke kaomi, ka hana a me ka mālama ʻana i nā kumukūʻai kiʻekiʻe, ua palena nā kumuwaiwai spectrum, ʻaʻole lawa nā kumuwaiwai pūnaewele, koʻikoʻi. e pili ana i ka ulu ʻana o ka ʻoihana ʻike a me ka ʻoihana kamaʻilio o Kina.
Me ka holomua o ka ʻepekema a me ka ʻenehana a me ka hoʻomaikaʻi mau ʻana i nā koi o nā kānaka no nā pūnaewele kamaʻilio, ʻaʻole hiki i ka wikiwiki kamaʻilio a me nā lawelawe i hāʻawi ʻia e nā ʻenehana 2G a me 3G ʻaʻole hiki ke hoʻokō i nā pono o nā kānaka.Ua kaupalena ʻia nā kumuwaiwai spectrum i noho ʻia e nā ʻenehana 2G a me 3G, a inā mākou e hoʻomau i ka hoʻohana ʻana i nā ʻenehana 2G a me 3G, e hoʻopau mākou i ka nui o nā kumuwaiwai spectrum.
ʻO ke kūlana o 2G a me 3G ma Kina: nui ka waihona mea hoʻohana, a lohi ka wikiwiki o ka haʻalele.
Nui loa ka helu o nā mea hoʻohana 2G ma Kina.Wahi a ka ʻikepili i hoʻokuʻu ʻia e ka Ministry of Industry and Information Technology, i ka makahiki 2020, aia he 273 miliona mau mea hoʻohana 2G ma ka pūnaewele, e helu ana no 17.15% o ka nui o nā mea hoʻohana.ʻO ka hapa nui o kēia poʻe he poʻe ʻelemakule ma nā wahi mamao, ʻoi aku ka liʻiliʻi o ke koi ʻana i nā kelepona akamai a ke kelepona nui nei.
Ua ʻōlelo ʻo Ling Li, he kumu aʻoaʻo ma ke kula o ka ʻike ʻepekema a me ka ʻenekinia ma ke Kulanui ʻo Fudan, ʻo ka ʻenehana ʻenehana ke ʻano maʻamau, a ʻo nā mea hoʻohana ke "haʻihaʻi" no nā pūnaewele 2G / 3G, akā ʻaʻole ka holomua o ka pō. no ka mea he nui nā mea hoʻohana e hoʻohana ana i nā pūnaewele 2G a i ʻole 3G.Eia kekahi, ma waho aʻe o nā kelepona kelepona, aia kekahi noi ʻē aʻe ʻaʻole hiki ke mālama ʻia, ʻo ia hoʻi, ʻo ka ʻōnaehana pūnaewele o nā mea i hoʻohana ʻia i ka hoʻokele kūlanakauhale, ke hoʻohana nei kekahi o kēia mau mea i nā pūnaewele 2G/3G e kamaʻilio.
Hiki ke hoʻohana ʻia ke kelepona paʻa no ka poʻe ʻelemakule?
Ua pane aku nā mea hana kūloko ma Guangzhou Kina ʻaʻole e loaʻa nā pūnaewele 2G a pono e hoʻohana ʻia nā hana VoLTE ma nā kelepona paʻalima.He lawelawe kelepona ʻo VoLTE e pili ana i nā pūnaewele 4G, a inā ʻaʻole ʻoe i kēia hiʻohiʻona ma kāu kelepona, ʻaʻole hiki iā ʻoe ke hoʻomau i ka hoʻohana ʻana a pono ʻoe e kūʻai i kelepona hou.I kēia manawa, manuahi ka hoʻonui ʻana i kahi kāleka SIM kelepona 2G i kahi kāleka SIM kelepona 4G a i ʻole 5G a ʻaʻohe pono e hoʻololi i ka hoʻolālā.
