LoRa VS LoRaWan

LoRa ndi lalifupi la Long Range.Ndi ukadaulo wapamtunda wotsika, wolumikizana ndi mtunda wautali.Ndi mtundu wa njira, yomwe mbali yake yaikulu ndi mtunda wautali wa kufalitsa opanda zingwe mu mndandanda womwewo (GF, FSK, etc.) kufalikira patali, vuto la kuyeza mtunda ndi mtunda umakhala pamtunda wautali.Itha kukulitsa nthawi 3-5 kuposa opanda zingwe zachikhalidwe pansi pamikhalidwe yomweyi.

LoRaWAN ndi muyezo wotseguka womwe umatanthawuza njira yolumikizirana yaukadaulo wa LoRa chip-based LPWAN ndipo LoRaWAN imatanthauzira Media Access Control (MAC) pagawo lolumikizira deta.Protocol imasungidwa ndi LoRa Alliance.

LoRaWAN yawonetsa momveka bwino monga pamwambapa kuti ndi protocol.Zomwe zimatchedwa protocol zimatchula ndondomeko ndi ndondomeko.Node iliyonse yogwirizana ndi LoRaWAN imayenera kutsatira zofunikira za LoRaWAN kuti athe kulumikizana.LoRa ndi njira yosinthira, ndipo LoRaWAN ndi pulogalamu yomangidwa motsatira njira ya LoRa yosinthira.Mwachidule, gawo la LoRaWAN limagwiritsa ntchito gawo la LoRa wamba, kenako limayika magawo kapena kutumiza ndikulandila ma sign malinga ndi malamulo ena.

Nthawi zambiri, gawo la LoRa node silingathe kulumikizana ndi gawo la node ya LoRaWAN, ngakhale magawo onse a ma module awiriwa ali ofanana.

Popeza LoRa imatanthawuza gawo laling'ono lakuthupi, zigawo zapamwamba zapaintaneti zinalibe.LoRaWAN ndi imodzi mwama protocol angapo omwe adapangidwa kuti afotokoze zigawo zapamwamba za netiweki.LoRaWAN ndi mtambo-based medium access control (MAC) layer protocol, koma imagwira ntchito makamaka ngati network layer protocol yowongolera kulumikizana pakati pa zipata za LPWAN ndi zida zomaliza monga njira yolumikizira, yosungidwa ndi LoRa Alliance.

LoRaWAN imatanthawuza njira yolumikizirana ndi kamangidwe kamaneti, pomwe gawo la thupi la LoRa limathandizira kulumikizana kwautali wautali.LoRaWAN ilinso ndi udindo woyang'anira ma frequency olumikizirana, kuchuluka kwa data, ndi mphamvu pazida zonse.Zipangizo zomwe zili pa netiweki ndizosasinthika ndipo zimatumizidwa ngati zili ndi data yotumiza.Deta yotumizidwa ndi chipangizo chakumapeto kumalandiridwa ndi zipata zingapo, zomwe zimatumiza mapaketi a data ku seva yapakati pamaneti.Zomwezo zimatumizidwa ku ma seva a pulogalamu.Tekinolojeyi ikuwonetsa kudalirika kwakukulu kwa katundu wocheperako, komabe, ili ndi zovuta zina zokhudzana ndi kutumiza kuvomereza.

Mongawopanga zigawo za RF passive components, Jingxin akhoza makonda kupanga zigawo zothandizira LoRaWan.pali mmodzifyuluta yamkati 868MHzikugwira ntchito kuchokera ku 864-872MHz yomwe ingagwire ntchito yankho ili.Zambiri zitha kuperekedwa.
