LoRa VS LoRaWan

He pōkole ʻo LoRa no ka Lā Loa. He haʻahaʻa haʻahaʻa, mamao-mamao pili pili ʻenehana. He ʻano ʻano ia, nona ka hiʻohiʻona nui ka lōʻihi lōʻihi o ka hoʻouna ʻole ʻana i ka moʻo like (GF, FSK, a me nā mea ʻē aʻe). Hiki iā ia ke hoʻonui i nā manawa 3-5 ma mua o ke kelepona kuʻuna ma lalo o nā kūlana like.

ʻO LoRaWAN kahi maʻamau ākea e wehewehe i ka protocol kamaʻilio o LoRa chip-based LPWAN ʻenehana a ʻo LoRaWAN e wehewehe i ka Media Access Control (MAC) ma ka papa loulou data. Mālama ʻia ka protocol e ka LoRa Alliance.

Ua hōʻike maopopo ʻia ʻo LoRaWAN e like me ka mea ma luna nei he protocol. ʻO ka mea i kapa ʻia ʻo protocol e kuhikuhi i kahi hoʻonohonoho o nā lula a me nā kaʻina hana. Pono kekahi node hoʻokō LoRaWAN e hahai i nā koi LoRaWAN e kamaʻilio. ʻO LoRa kahi ʻano modulation, a ʻo LoRaWAN kahi noi i kūkulu ʻia e like me ke ʻano modulation LoRa. Hoʻopuka maʻalahi, hoʻohana ka module LoRaWAN i kahi module LoRa maʻamau, a laila hoʻonohonoho i nā ʻāpana a hoʻouna a loaʻa i nā hōʻailona e like me kekahi mau lula.

ʻO ka mea maʻamau, ʻaʻole hiki i ka LoRa node module ke kamaʻilio me ka LoRaWAN node module, ʻoiai inā like nā ʻāpana āpau o nā modula ʻelua.

Ma muli o ka wehewehe ʻana o LoRa i ka papa kino haʻahaʻa, ua nele nā ​​papa pūnaewele luna. ʻO LoRaWAN kekahi o nā protocols i kūkulu ʻia e wehewehe i nā papa luna o ka pūnaewele. ʻO LoRaWAN kahi protocol layer-based medium access control (MAC), akā hana nui ʻia ma ke ʻano he protocol layer network no ka hoʻokele ʻana i ke kamaʻilio ma waena o nā puka LPWAN a me nā ʻaoʻao hope-node ma ke ʻano he protocol routing, mālama ʻia e ka LoRa Alliance.

Ho'ākāka ʻo LoRaWAN i ka protocol kamaʻilio a me ka hoʻolālā ʻōnaehana no ka pūnaewele, ʻoiai ʻo ka LoRa physical layer e hiki ai i ka loulou kamaʻilio lōʻihi. ʻO LoRaWAN ke kuleana no ka hoʻokele ʻana i nā alapine kamaʻilio, ka helu data, a me ka mana no nā polokalamu āpau. ʻAʻole like ʻole nā ​​polokalamu ma ka pūnaewele a hoʻouna i ka wā e loaʻa ai ka ʻikepili e hoʻouna ai. Loaʻa ka ʻikepili i hoʻouna ʻia e kahi ʻaoʻao hope-node e nā ʻīpuka lehulehu, e hoʻouna i nā ʻeke ʻikepili i kahi kikowaena kikowaena kikowaena. Hoʻouna ʻia ka ʻikepili i nā kikowaena noi. Hōʻike ka ʻenehana i ka hilinaʻi kiʻekiʻe no ka ukana haʻahaʻa, akā naʻe, aia kekahi mau pilikia hana e pili ana i ka hoʻouna ʻana i nā hōʻoia.

E like me kamea hana i nā ʻāpana passive RF, Hiki iā Jingxin ke hoʻolālā maʻamau i nā ʻāpana e kākoʻo iā LoRaWan. aia kekahikānana lua 868MHze hana ana mai ka 864-872MHz hiki ke hana pono no kēia hoʻonā. Hiki ke hāʻawi ʻia nā kikoʻī hou aku.
