Ke hoʻomau nei ka ulu ʻana o ka Internet of Things (IoT), ʻo nā protocol kamaʻilio like ʻole e pāʻani i nā kuleana koʻikoʻi i nā hiʻohiʻona noiʻi like ʻole. ʻO LoRaWAN a me WiFi (ʻo ia hoʻi ʻo WiFi HaLow) ʻelua mau ʻenehana koʻikoʻi i hoʻohana ʻia i ka kamaʻilio IoT, hāʻawi kēlā me kēia i nā pono kūʻokoʻa no nā pono kikoʻī. Hoʻohālikelike kēia ʻatikala iā LoRaWAN a me WiFi, e kōkua ana iā ʻoe e koho i ka hopena kūpono no kāu papahana IoT.
1. Kūlana Kūkākūkā: LoRaWAN vs WiFi
LoRaWAN: ʻIke ʻia no kāna mau mana lōʻihi loa, kūpono ʻo LoRaWAN no nā noi e koi ana i ka hoʻoili ʻikepili lōʻihi. Ma nā wahi kuaʻāina, hiki i ka LoRaWAN ke hele i kahi mamao a hiki i 15-20 mau kilomita, ʻoiai ma nā kaona kūlanakauhale, uhi ʻia ʻo 2-5 mau kilomita. ʻO kēia ka mea e koho ai no ka mahiʻai akamai, ka nānā mamao, a me nā hiʻohiʻona ʻē aʻe e pono ai ka uhi ākea.
WiFi: Loaʻa i ka WiFi maʻamau ka lōʻihi o ke kamaʻilio ʻana, i kaupalena ʻia i nā pūnaewele wahi kūloko. Eia nō naʻe, hoʻonui ʻo WiFi HaLow i ka laulā ma kahi o 1 kilomika ma waho, ʻoiai e hāʻule mau ana ka pōkole e hoʻohālikelike ʻia me LoRaWAN. No laila, ʻoi aku ka maikaʻi o WiFi HaLow no nā polokalamu IoT pōkole i waena.
2. Hoʻohālikelike i ka helu hoʻoili ʻikepili
LoRaWAN: Hoʻohana ʻo LoRaWAN me nā pākēneka ʻikepili haʻahaʻa, maʻamau mai 0.3 kbps a i 50 kbps. He kūpono ia no nā noi ʻaʻole koi i ka bandwidth kiʻekiʻe a hiki ke hana me ka liʻiliʻi ʻole o ka hoʻouna ʻana i nā ʻikepili, e like me nā mea ʻike kaiapuni a i ʻole nā mika wai akamai.
ʻO WiFi HaLow: Ma ka ʻaoʻao ʻē aʻe, hāʻawi ʻo WiFi HaLow i nā helu hoʻoili ʻikepili kiʻekiʻe, mai 150 kbps a i kekahi mau Mbps. He mea kūpono kēia no nā noi e makemake ana i ka bandwidth kiʻekiʻe, e like me ka nānā wikiō a i ʻole ka hoʻoili ʻana i ka ʻikepili paʻakikī.
3. Hoʻohana Mana: ʻO ka pono o LoRaWAN
LoRaWAN: ʻO kekahi o nā pōmaikaʻi nui loa o LoRaWAN ʻo kona hoʻohana haʻahaʻa haʻahaʻa. Hiki i nā mea hoʻohana LoRaWAN ke hoʻohana no nā makahiki he nui ma ka pā hoʻokahi, e kūpono ana ia no nā wahi mamao a paʻakikī paha, e like me nā mea ʻike mahiʻai a i ʻole nā mea nānā ʻoihana.
WiFi HaLow: ʻOiai ʻoi aku ka ikaika o WiFi HaLow ma mua o WiFi kuʻuna, ʻoi aku ka kiʻekiʻe o kona hoʻohana mana ma mua o LoRaWAN. No laila ʻoi aku ka maikaʻi o WiFi HaLow no nā noi IoT kahi i manaʻo nui ʻole ai ka hoʻohana ʻana i ka mana, akā pono ke kaulike ma waena o ka ikaika o ka ikehu a me nā helu ʻikepili kiʻekiʻe.
4. Hoʻolālā Hoʻololi: LoRaWAN vs WiFi
LoRaWAN: Hoʻohana ʻia ʻo LoRaWAN i nā alapine ʻole i laikini ʻia (e like me 868 MHz ma ʻEulopa a me 915 MHz ma US), ʻo ia ka mea hiki ke kau ʻia me ka ʻole o ka pono o nā laikini spectrum. ʻO kēia ka mea kūpono no ka hoʻolaha nui ʻana i nā noi IoT kūloko a i ʻole ʻoihana. Eia nō naʻe, ʻo ka hoʻonohonoho ʻana i kahi pūnaewele LoRaWAN e koi i ka hoʻokomo ʻana i nā ʻīpuka a me nā ʻōnaehana, pono ia no nā hiʻohiʻona kahi mea koʻikoʻi ke kamaʻilio lōʻihi.
WiFi HaLow: Hoʻohui maʻalahi ʻo WiFi HaLow i nā ʻōnaehana WiFi i loaʻa, e maʻalahi ka hoʻonohonoho ʻana i nā wahi me nā pūnaewele WiFi e kū nei, e like me nā hale a me nā keʻena. ʻO kona lōʻihi lōʻihi a me ka helu ʻikepili kiʻekiʻe e kūpono ia no nā hale akamai, IoT ʻenehana, a me nā noi like ʻole't makemake i ke kamaʻilio lōʻihi.
5. Nā hihia hoʻohana maʻamau
LoRaWAN: He kūpono ʻo LoRaWAN no nā noi lōʻihi, haʻahaʻa haʻahaʻa, a me nā noi haʻahaʻa haʻahaʻa, e like me:
- ʻO ka mahiʻai akamai (e laʻa, ka nānā ʻana i ka makū o ka lepo)
- Ke ana pono no ka wai, ke kinoea, a me ka wela
- Ka nānā ʻana a me ka nānā ʻana i nā waiwai mamao
ʻO WiFi HaLow: ʻOi aku ka maikaʻi o ka WiFi HaLow no nā noi pōkole a me waena e koi ana i nā helu ʻikepili kiʻekiʻe a me ka uhi ʻoi aku ka maikaʻi, e like me:
- Nā polokalamu home akamai (e laʻa, nā kāmela palekana, thermostats)
- Ka nānā ʻana i nā mea hana IoT ʻoihana
- Nā lako olakino a hoʻoikaika kino
Loaʻa i nā ʻenehana ʻelua ko lāua mau ikaika
Ma ka hoʻohālikelike ʻana iā LoRaWAN a me WiFi, maopopo ka loaʻa ʻana o nā ʻenehana ʻelua i ko lākou ikaika kūʻokoʻa i nā hiʻohiʻona IoT like ʻole. ʻO LoRaWAN ka koho maikaʻi loa no nā noi e koi ana i ke kamaʻilio lōʻihi, ka hoʻohana haʻahaʻa haʻahaʻa, a me ka lawe ʻana i ka ʻikepili liʻiliʻi. Ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka maikaʻi o WiFi HaLow i nā hiʻohiʻona kahi i kiʻekiʻe ai ka nui o ka ʻikepili, nā pae kamaʻilio pōkole, a me nā ʻōnaehana WiFi e pono ai.
ʻO ke koho ʻana i ka ʻenehana kamaʻilio IoT kūpono e pili ana i kāu mau pono kikoʻī. Inā makemake kāu papahana i ka hoʻoili ʻikepili mamao me ka mana haʻahaʻa a me nā koi haʻahaʻa haʻahaʻa, kūpono ʻo LoRaWAN. Inā makemake ʻia nā helu ʻikepili kiʻekiʻe a me nā pae kamaʻilio pōkole, ʻo WiFi HaLow ka koho ʻoi aku ka maikaʻi
ʻO ka hoʻomaopopo ʻana i nā ʻokoʻa ma waena o LoRaWAN a me WiFi HaLow hiki iā ʻoe ke koho i ka ʻenehana kamaʻilio maikaʻi loa no kāu hoʻonā IoT a hoʻokele i ka hoʻomohala ʻoi aku ka maikaʻi.
