ʻO ka protocol LoRaWAN ma ke ala maʻalahi a kaulana loa

ʻO LoRaWAN kahi hoʻonohonoho o nā protocol kamaʻilio a me nā ʻōnaehana ʻōnaehana i hoʻolālā ʻia no nā pūnaewele kamaʻilio lōʻihi LoRa.

 

Hoʻokumu nui ʻia nā ʻupena LoRa i nā terminal (nā modules LoRa i kūkulu ʻia), nā ʻīpuka (a i ʻole nā ​​kahua kahua), nā kikowaena pūnaewele, a me nā kikowaena noi. ʻO ka hoʻolālā pūnaewele ʻo LoRaWAN kahi topology hōkū maʻamau kahi o ka ʻīpuka LoRa he kumu no ka hoʻouna ʻana akaka, e hoʻopili ana i nā hāmeʻa terminal i ka hope hope me kahi kikowaena kikowaena. Hoʻohana ka mea hoʻopau i ka protocol LoRa e kamaʻilio me hoʻokahi a ʻoi aku paha nā ʻīpuka. Kūkākūkā nā node a pau me ka ʻīpuka ma nā ʻaoʻao ʻelua.

 

Ma kekahi mau polokalamu ʻōnaehana LoRaWan, hoʻohana ʻia nā kānana ma ke ʻano he ala e koho ai i nā kaha alapine.

E like me ka mea hoʻolālā kānana, ua hoʻomohala ʻo Jingxin i nā kānana bandpass like ʻole no ka band 868MHz, aia kekahi kānana bandpass cavity maʻamau me IP67 wai wai no ka ʻōnaehana Lorawan, ʻoi aku ka kikoʻī ma https://www.cdjx-mw.com/waterproof-ip65 -bandpass-cavity-filter-operating-mai-863-870mhz-jx-cf1-860m870m-40nwp-product/

inā makemake ʻoe i kahi kānana hoʻolālā maʻamau no LoRaWan, e ʻoluʻolu e kūkākūkā me mākou.
