I te wā e whiriwhiri ana i waenga i te NB-IoT me te 4G mō ngā mita wai ultrasonic, me hangai te whakatau ki ngā whakaritenga motuhake me ngā horopaki tono. Kei raro nei he tātaritanga whakatairite o ngā hangarau e rua:
1. Te Whakamahinga Mana
- NB-IoT: E whakamahi ana i te hangarau whānui-rahi iti-mana (LPWA), me te noho tonu o te kōwae i roto i te aratau moe i te nuinga o te wā. Mā te whakamahi i ngā pākahiko AA, ka neke atu i te 10 tau te roa o tōna oranga mahi, he mea tino pai mō ngā mita wai ultrasonic me ngā tono whakapaunga hiko tino kaha me te whakaiti i te auau o te whakakapinga pākahiko.
- 4G: He nui ake te hiko e pau ana, ka poto ake te ora o te pākahiko, he herenga nui tēnei mō ngā tono mita wai e whakamahia ana e te pākahiko.
2. Te Kapinga Whatunga
- NB-IoT: E tuku ana i te whakanui tohu 20dB ki te whakaritea ki te GPRS, e āhei ai te kapinga hōhonu pai rawa atu i roto i ngā taiao uaua pēnei i ngā papa ahumahi, ngā puna paipa, ngā whakaurunga raro whenua rānei e ngāwari ai te aukati i ngā tohu.
- 4G: E whakamanamana ana ki te whānuitanga o te kapinga engari ka uaua pea te pumau i ngā wāhi tūmatanui, i ngā taiao uaua rānei (hei tauira, ngā rūma o raro o te tāone) nā te ngoikore o te urunga tohu.
3. Te Mahi Tuku Raraunga
- NB-IoT: I hangaia mō te tuku raraunga iti-rahi, iti-auau (ko te tikanga kotahi i roto i te 24 hāora mō te ine wai). He pai mō ngā horopaki he iti ngā whakaritenga wā-tūturu, pērā i te pānui mita mamao me te kohikohi raraunga kai.
- 4G: Ka tuku raraunga tere-teitei, iti-roa, e tautoko ana i te aroturukitanga wā-tūturu me ngā whakatūpato inamata. Nā tēnei ka pai mō ngā tono e hiahia ana ki te urupare wā-poto, pērā i te whakahaere wai ahumahi, te kimi turuturu, te aroturuki hanganga nui rānei.
4. Te utu
- NB-IoT: He iti ake te utu mō ngā waeine whakawhitiwhiti kōrero. Ahakoa he taurite ngā utu mō ngā waeine, he iti noa iho ngā utu whakahaere mō te wā roa (hei tauira, ngā mahere raraunga) nā te iti o te whakamahinga raraunga.
- 4G: He nui ake ngā utu mō ngā kōwae me ngā mahere raraunga. Hei tāpiri, tera pea ka hiahiatia he hanganga tautoko matatini ake mō ngā pūnaha e hangai ana ki te 4G, ka nui ake ai ngā utu whakatinanatanga me te tiaki whānui.
5. Te kaha o te hononga
- NB-IoT: Ka taea e te teihana turanga kotahi te tautoko i ngā tekau mano o ngā hononga, e whakarato ana i te kaha urunga 50–100 ngā wā o te kaha uru atu o ngā hangarau ahokore tuku iho. Nā tēnei he tino pai mō ngā whakatinanatanga IoT nui, pērā i ngā whatunga tuku wai o te tāone me ngā whakaurunga mita nui.
- 4G: He iti te kaha hononga i te wā kotahi, ā, kāore i te tino whai hua mō ngā tono IoT nui, iti te tere raraunga.
Whakarāpopototanga o te Taunakitanga
- Kōwhiria te NB-IoT mō te ine wai kāinga whānui, te aroturukitanga wai mamao, te aroturukitanga wai ā-tāone nui rānei—arā, ko ngā āhuatanga e aro nui ana ki te iti o te whakamahinga hiko, te whānui o te kapinga, me te whai huatanga o te utu, kaua ki te tuku raraunga wā-tūturu.
- Kōwhiria te 4G mō te whakahaere wai ahumahi, te kimi turuturu i te wā tūturu, ngā pūnaha aroturuki nui rānei e hiahia ana ki te tuku raraunga tere-nui, iti-roa, me ngā āheinga whakatūpato inamata.
