I te whakatinanatanga o ngā whatunga 4G me te 5G, kei te ahu whakamua tonu te mahi tuimotu 2G me te 3G i roto i te maha o ngā whenua me ngā rohe. Kei roto i tēnei tuhinga he tirohanga whānui mō ngā tukanga tuimotu 2G me te 3G puta noa i te ao.
I te mea kei te haere tonu te whakatinanatanga o ngā whatunga 5G puta noa i te ao, kei te tata mutu te 2G me te 3G. Ka pā te whakaiti i te rahi o te 2G me te 3G ki ngā whakatinanatanga o te ioT mā te whakamahi i ēnei hangarau. I konei, ka matapakihia e mātou ngā take me aro atu ngā umanga i te wā o te tukanga tuimotu 2G/3G me ngā mahi ārai.
Te pānga o te 2G me te 3G tuimotu ki te hononga IoT me ngā mahi ārai
I te mea kei te whakamahia te 4G me te 5G puta noa i te ao, kei te ahu whakamua tonu te mahi tuimotu 2G me te 3G i roto i te maha o ngā whenua me ngā rohe. He rerekē te tukanga mō te kati i ngā whatunga i ia whenua, i runga i te whakaaro o ngā kaiwhakahaere ā-rohe ki te whakawātea i ngā rauemi whāiti whai hua, i runga rānei i te whakaaro o ngā kaiwhakahaere whatunga pūkoro ki te kati i ngā whatunga ina kore e tika kia haere tonu ngā ratonga o nāianei ki te mahi.
Ko ngā whatunga 2G, kua neke atu i te 30 tau e wātea ana ki te hokohoko, he tūāpapa pai mō te whakatinana i ngā otinga iot kounga teitei i runga i te tauine ā-motu me te ao. Ko te roa o te huringa ora o te maha o ngā otinga iot, he maha ngā wā neke atu i te 10 tau, ko te tikanga he nui tonu ngā taputapu ka taea te whakamahi i ngā whatunga 2G anake. Nō reira, me mahi ngā mahi hei whakarite kia haere tonu te mahi a ngā otinga iot ina kore e whakamahia te 2G me te 3G.
Kua tīmatahia, kua oti rānei te whakaiti i te rahi o ngā whatunga 2G me te 3G i ētahi whenua, pērā i te US me Ahitereiria. He rerekē ngā rā i ētahi atu whenua, ā, ko te nuinga o Ūropi kua whakaritea mō te mutunga o te tau 2025. I te wā roa, ka mutu katoa ngā whatunga 2G me te 3G i te mākete, nō reira he raruraru tēnei e kore e taea te karo.
He rerekē te tukanga mo te momotu i te 2G/3G i ia wāhi, i runga i ngā āhuatanga o ia mākete. He maha ake ngā whenua me ngā rohe kua pānuitia ngā mahere mō te 2G me te 3G tuimotu. Ka piki haere tonu te maha o ngā whatunga ka kati. E matapaetia ana ka katihia neke atu i te 55 ngā whatunga 2G me te 3G i waenga i te tau 2021 me te 2025, e ai ki ngā raraunga a te GSMA Intelligence, engari kāore e tika kia whakakorea ngā hangarau e rua i te wā kotahi. I ētahi mākete, e matapaetia ana ka haere tonu te mahi a te 2G mō te tekau tau neke atu rānei, nā te mea ko ngā ratonga motuhake pēnei i ngā utu pūkoro i Āwherika me ngā pūnaha waea ohorere waka (eCall) i ētahi atu mākete e whakawhirinaki ana ki ngā whatunga 2G. I roto i ēnei āhuatanga, ka roa pea te mahi a ngā whatunga 2G.
Āhea ka mutu te 3G i te mākete?
Kua roa te wā e whakamaheretia ana te whakakorenga o ngā whatunga 3G, ā, kua whakawetohia i roto i ētahi whenua. Kua tutuki i ēnei mākete te whānuitanga o te kapinga 4G, ā, kei mua i te rōpū i roto i te whakatinanatanga o te 5G, nō reira he mea tika kia katihia ngā whatunga 3G me te tuku anō i te whānuitanga ki ngā hangarau o te whakatupuranga e whai ake nei.
Tae noa mai ki tēnei wā, he nui ake ngā whatunga 3G kua katihia i Ūropi i te 2G, ā, kotahi te kaiwhakahaere i Denmark i kati i tana whatunga 3G i te tau 2015. E ai ki a GSMA Intelligence, e 19 ngā kaiwhakahaere i roto i ngā whenua Ūropi e 14 e whakamahere ana ki te kati i ā rātou whatunga 3G i te tau 2025, ā, e waru noa iho ngā kaiwhakahaere i roto i ngā whenua e waru e whakamahere ana ki te kati i ā rātou whatunga 2G i te wā kotahi. Kei te piki haere te maha o ngā kati whatunga i te mea e whakaatu ana ngā kaikawe i ā rātou mahere. Te kati o te whatunga 3G o Ūropi Whai muri i te whakamahere tupato, kua panuitia e te nuinga o ngā kaiwhakahaere ā rātou rā kati 3G. Ko tētahi ia hou e puta ake ana i Ūropi ko te whakaroa a ētahi kaiwhakahaere i te wā whakahaere kua whakaritea mō te 2G. Hei tauira, i te UK, e kī ana ngā mōhiohio hou kua whakaroahia te rā whakatinanatanga kua whakaritea mō te tau 2025 nā te mea kua whakaritea e te kāwanatanga he whakaaetanga me ngā kaiwhakahaere waea pūkoro kia mau tonu te whakahaere o ngā whatunga 2G mō ngā tau torutoru e whai ake nei.
· Kua kati ngā whatunga 3G o Amerika
Kei te pai te haere o te katinga o te whatunga 3G i te Hononga o Amerika me te whakatinanatanga o ngā whatunga 4G me te 5G, me te whai a ngā kaikawe nui katoa ki te whakaoti i te whakatinanatanga o te 3G i te mutunga o te tau 2022. I ngā tau kua pahure ake nei, kua arotahi te rohe o Amerika ki te whakaiti i te rahi o te 2G i te mea kua whakatinanahia e ngā kaikawe te 5G. Kei te whakamahi ngā kaiwhakahaere i te whānuitanga i tukuna e te whakatinanatanga o te 2G hei whakatutuki i te hiahia mō ngā whatunga 4G me te 5G.
· Ka kati ngā tukanga i ngā whatunga 2G o Āhia
Kei te pupuri tonu ngā kaiwhakarato ratonga i Āhia i ngā whatunga 3G, me te kati i ngā whatunga 2G hei whakawhiti i te whānuitanga ki ngā whatunga 4G, e whakamahia nuitia ana i te rohe. I te mutunga o te tau 2025, e matapaetia ana e GSMA Intelligence kia 29 ngā kaiwhakahaere ka kati i ā rātou whatunga 2G, ā, kia 16 ka kati i ā rātou whatunga 3G. Ko Taiwan anake te rohe i Āhia kua kati i ā rātou whatunga 2G (2017) me 3G (2018).
I Āhia, tera ētahi tūāhua rerekē: i tīmata ngā kaiwhakahaere ki te whakaiti i te rahi o te 3G i mua i te 2G. Hei tauira, i Mareia, kua kati ngā kaiwhakahaere katoa i ā rātou whatunga 3G i raro i te tirotiro a te kāwanatanga.
I Initonīhia, e rua o ngā kaiwhakahaere e toru kua kati i ā rātou whatunga 3G, ā, kei te whakamahere te tuatoru ki te mahi pēnā (i tēnei wā, kāore tētahi o ngā kaiwhakahaere e toru e whakamahere ana ki te kati i ā rātou whatunga 2G).
· Kei te whakawhirinaki tonu a Āwherika ki ngā whatunga 2G
I Āwherika, e rua te rahi o te 2G i te 3G. E 42% tonu o te katoa o ngā waea āhuatanga, ā, ko te iti o te utu e akiaki ana i ngā kaiwhakamahi ki te whakamahi tonu i ēnei taputapu. Nā tēnei, kua iti te urunga mai o ngā waea atamai, nō reira he iti noa ngā mahere kua panuitia hei whakakore i te Ipurangi i te rohe.
