Ko te 5G te hangarau whakawhitiwhiti kōrero o te reanga tuarima, ko te nuinga o ngā āhuatanga ko te roangaru mirimita, te whānui rawa, te tere tino teitei, me te iti rawa o te whakaroa. Kua tutuki i te 1G te whakawhitiwhiti kōrero reo anaro, ā, kāore he mata o te tuakana, ā, ka taea anake te waea atu; kua tutuki i te 2G te mamati i te whakawhitiwhiti kōrero reo, ā, he mata iti tō te mīhini mahi hei tuku karere kuputuhi; kua tutuki i te 3G te whakawhitiwhiti kōrero rongorau i tua atu i te reo me ngā whakaahua, ka nui ake te mata mō te mātakitaki whakaahua; kua tutuki i te 4G te urunga ipurangi tere-teitei ā-rohe, ā, ka taea e ngā waea atamai mata nui te mātakitaki i ngā ataata poto, engari he pai te tohu i ngā tāone nui, ā, he ngoikore i ngā tāone tuawhenua. Ka arotahi te 1G~4G ki te whakawhitiwhiti kōrero watea me te whai hua i waenga i te tangata, ko te 5G ka taea te hononga o ngā mea katoa i ngā wā katoa, i ngā wāhi katoa, ka taea ai e te tangata te tumanako ki te whai wāhi tukutahi ki ngā mea katoa o te Ao mā te rere ora me te kore he rerekētanga wā.
Ko te taenga mai o te wā 5G me te whakaurunga mai o te hangarau Massive MIMO kua arahi tika ki ngā au e toru i roto i te whanaketanga o ngā pūihi teihana turanga 5G:
1) Te whanaketanga o ngā pūihi kore mahi ki ngā pūihi hohe;
2) Kaiwhāngai whakakapinga muka whatu;
3) Kua whakauruhia te RRH (upoko mamao auau reo irirangi) me te pūihi.
I te whanaketanga tonu o ngā whatunga whakawhitiwhiti kōrero ki te 5G, ko ngā pūihi whakaatu (te wehewehenga wāhi maha-pūihi), ngā pūihi maha-rama (te whakakīkī whatunga), me ngā pūihi maha-roopu (te whakawhānui i te whānuitanga o te hihi) ka noho hei momo matua o te whanaketanga pūihi teihana turanga a meake nei.
I te taenga mai o ngā whatunga 5G, kei te huri haere tonu ngā hiahia o ngā kaiwhakahaere nui mō ngā whatunga pūkoro. Hei whakatutuki i te kapinga whatunga katoa, he maha ake ngā momo pūihi whakatikatika teihana turanga e whakamahia whānuitia ana i roto i te ao whakawhitiwhiti pūkoro. Mō te pūihi auau-whā, hei whakatutuki i te whakahaere i tōna koki hiko whakararo, e toru ngā momo matua o ngā taputapu whakahaere whakatikatika hiko i tēnei wā, tae atu ki te huinga o ngā kaiwhakahaere whakatikatika hiko motuka takirua kua hangaia, he kaiwhakahaere whakatikatika hiko motuka takirua me te tikanga whakawhiti tuku, me ngā kaiwhakahaere whakatikatika hiko motuka e whā kua hangaia. Ka kitea ahakoa ko tēhea taputapu e whakamahia ana, kāore e taea te wehe atu i te whakamahinga o ngā motuka pūihi.
Ko te hanganga matua o te motuka antenna whakahāngai hiko o te teihana turanga he mīhini whakauru whakaheke motuka e titoa ana e te motuka tuku me te pouaka whakaheke, he mahi whakatikatika whakaheke; Ka whakaratohia e te motuka tuku te tere putanga me te tere taipana iti, ka honoa te pouaka ki te motuka tuku hei whakaiti i te tere putanga o te motuka tuku i te wa e whakanui ana i te taipana, ka tutuki te hua tuku pai; Ko te pouaka motuka antenna whakahāngai hiko o te teihana turanga te nuinga o te whakamahi i nga tawhā hangarau, te mana, me te mahi a te pouaka motuka kua whakaritea kia pai ake ai te whakatutuki i nga mea taiao penei i te taiao, te āhuarangi, te rereketanga o te pāmahana, me te whakatutuki i te hua tuku pai me nga whakaritenga ora ratonga.
