Ka arotakehia e tēnei tuhinga te whanaketanga, ngā hangarau e whakamahia ana, me te pānga o ngā pūnaha whakawhitiwhiti kōrero pūkoro.
Te Whanaketanga o ngā Pūnaha Whakawhitiwhiti Kōrero Pūkoro
1. Te Whakatipuranga Tuatahi (1G)
Mai i te mutunga o te tekau tau atu i 1970 ki te tekau tau atu i 1980, i whakaurua tuatahitia ngā whakawhitiwhitinga waea pūkoro mā te whakamahi i ngā pūnaha anaro e mōhiotia ana ko te 1G. Ko tētahi o ngā pūnaha rongonui o tēnei whakatipuranga ko te Advanced Mobile Phone System (AMPS), i whakamahia i te Hononga o Amerika. Ko te āhuatanga matua o te 1G ko te tuku raraunga anaro e tautoko ana i ngā ratonga reo anake. Ahakoa he hangarau hou tēnei i tōna wā, he maha ngā ngoikoretanga, pērā i te iti o te kaha whatunga me te ngoikore o te haumarutanga.
2. Te Reanga Tuarua (2G)
I whakarewaina i te tīmatanga o te tekau tau atu i 1990, ko te 2G he peke nui mai i te hangarau anaro ki te hangarau matihiko. Ko te paerewa Global System for Mobile Communications (GSM) tētahi o ngā hangarau matua o taua wā, i āhei ai te whai huatanga o te whānuitanga o te ira, me te haumaru ake, me te pono hoki o ngā whakawhitiwhitinga kōrero. I tēnei wā, i tua atu i ngā ratonga reo, i whakaurua mai hoki ngā karere kuputuhi (SMS) me ngā karere rongorau (MMS).
3. Te Whakatipuranga Tuatoru (3G)
I tukuna tuatahitia i ngā tau tōmua o te tekau tau atu i 2000, nā te hangarau 3G i tere ake ai, i pono ake ai hoki ngā āheinga ipurangi ki ngā kaiwhakamahi waea pūkoro. Nā tēnei hangarau i taea ai te tuku raraunga mō ngā ratonga rongorau maha pēnei i te hui ataata, me te ipurangi pūkoro hoki. Ko te UMTS (Universal Mobile Telecommunications System) me te CDMA2000 ngā paerewa matua e rua o te hangarau 3G.
4. Te Whakatipuranga Tuawhā (4G)
I ngā tau 2010, ka tīmata te hangarau 4G ki te horapa, me te tuku tere me te kaha whatunga teitei ake i te 3G. Ko te hangarau Long Term Evolution (LTE) te hangarau rongonui o tēnei wā, e taea ai te tango i ngā tere tae atu ki ngā rau megabits ia hekona. Nā tēnei i whakatakoto te ara mō ngā tono e hiahia ana ki te whānui o te hononga pēnei i te roma ataata HD, te petipeti ipurangi, me ngā tono kapua.
5. Te Whakatipuranga Tuarima (5G)
Ko te whakatupuranga hou, ko te 5G, i tīmata te whakarewatanga arumoni i te mutunga o te tekau tau atu i 2010 me te tīmatanga o te tekau tau atu i 2020. Me ngā tere e eke ana ki ētahi gigabits ia hekona me te iti rawa o te whakaroa, e matapaetia ana ko te 5G te mea matua hei whakahohe mō te Ipurangi o ngā Mea (IoT), ngā waka motuhake, me te maha atu o ngā tono hangarau matatau. E oati ana tēnei hangarau ki te huri i te huarahi e taunekeneke ai tātou me te hangarau, me te whakatuwhera i te kuaha ki ngā auahatanga o muri mai.
