Pūhiko Pai rawa atu mō ngā Pūrere IoT
Kei roto i ngā āhuatanga maha o te ao ngā taputapu Ipurangi o ngā Mea (IoT): ngā whare atamai, ngā ahumahi, ngā ahuwhenua tino tika, te hauora, tae atu ki ngā tāone atamai. Kei muri i te ngāwari me te aunoatanga e tukuna ana, kotahi te wāhanga e whakatau ana i te angitu o te whakatinanatanga o te IoT i te mara: ko te pākahiko. Ko ngā taputapu IoT e hiahiatia ana kia roa te mahi, kia pumau, kia iti hoki te tiaki—he maha ngā wā ka whakanohoia ki ngā wāhi uaua ki te tae atu. Nō reira, ko te whiriwhiri i te pākahiko pai rawa atu mō ngā taputapu IoT ehara i te mea ko te whiriwhiri noa i te "kaha nui rawa atu," engari ko te mea e pai ana ki te kōtaha mana, te taiao mahi, me te roa o te oranga o te taputapu.
He aha te mea nui o te whiriwhiri pākahiko IoT?
He tauira ahurei te mahi a te nuinga o ngā pūnga IoT: ka moe rātou i te nuinga o te wā, kātahi ka ara ake mō te wā poto ki te ine i ngā pūoko me te tuku raraunga. Ka taea e te iahiko te tino iti i te wā moe (microamperes), engari i te wā tuku reo irirangi ka taea te piki tere (tekau ki te rau milliamperes) mō te wā poto. Hei tāpiri, he maha ngā wā ka honoa te IoT me ngā kawa penapena-hiko pēnei i te BLE, Zigbee, LoRaWAN, NB-IoT, LTE-M rānei. Nā ēnei āhuatanga katoa ka nui ake te hiranga o ngā āhuatanga o te pākahiko—pērā i te ngaohiko whakatauranga, te ātete ngaru, te tuku-ake-ake, me te mahi i ngā pāmahana tino nui—i te tau mAh anake.
