I-LoRa imfutshane kuluhlu olude. Bubuchwephesha boqhagamshelwano olusondeleyo kumgama ophantsi. Luhlobo lwendlela, eyona nto ibaluleke kakhulu kumgama omde wokuhanjiswa kwe-wireless kuthotho olufanayo (i-GF, i-FSK, njl. njl.) isasazeke ngakumbi, ingxaki yokulinganisa umgama kunye nomgama okhoyo kumgama omde. Inokwandisa amaxesha angama-3-5 ngaphezulu kwe-wireless yendabuko phantsi kweemeko ezifanayo.
I-LoRaWAN ngumgangatho ovulekileyo ochaza iprotocol yonxibelelwano ye-LoRa chip-based LPWAN iteknoloji kwaye i-LoRaWAN ichaza uLawulo loFikelelo lweMedia (MAC) kwinqanaba lekhonkco ledatha. Iprothokholi igcinwa yi-LoRa Alliance.
I-LoRaWAN iye yazisa ngokucacileyo njengalapha ngasentla ukuba yiprotocol. Into ebizwa ngokuba yiprotocol ichaza uluhlu lwemithetho kunye neenkqubo. Nayiphi na i-node ethobelayo ye-LoRaWAN kufuneka ilandele iimfuno ze-LoRaWAN ukunxibelelana. I-LoRa yindlela yokumodareyitha, kwaye i-LoRaWAN sisicelo esakhiwe ngokwendlela yokumodareyitha ye-LoRa. Ukubeka ngokulula, imodyuli yeLoRaWAN isebenzisa imodyuli yeLoRa eqhelekileyo, kwaye emva koko ibeka iiparamitha okanye ithumele kwaye ifumane imiqondiso ngokwemigaqo ethile.
Ngokuqhelekileyo, imodyuli ye-node ye-LoRa ayikwazi ukunxibelelana nemodyuli ye-node ye-LoRaWAN, nokuba zonke iiparameters zeemodyuli ezimbini ziyafana.
Kuba i-LoRa ichaza umaleko osezantsi womzimba, iileya zenethiwekhi eziphezulu zazingekho. I-LoRaWAN yenye yeeprothokholi ezininzi ezaphuhliswayo ukuchaza iileya eziphezulu zenethiwekhi. I-LoRaWAN yi-cloud-based access control access (MAC) layer protocol, kodwa isebenza ikakhulu njenge-network layer protocol yokulawula unxibelelwano phakathi kwamasango e-LPWAN kunye nezixhobo ze-end-node njengeprotocol yomzila, egcinwe yi-Alliance ye-LoRa.
I-LoRaWAN ichaza iprotocol yonxibelelwano kunye noyilo lwenkqubo yenethiwekhi, ngelixa i-LoRa layer yomzimba yenza ikhonkco lonxibelelwano olude. I-LoRaWAN ikwanoxanduva lokulawula iifrikhwensi zonxibelelwano, izinga ledatha, kunye namandla azo zonke izixhobo. Izixhobo kuthungelwano zi-asynchronous kwaye zihambisa xa zinedatha ekhoyo yokuthumela. Idatha ethunyelwa ngesixhobo se-end-node ifunyanwa ngamasango amaninzi, athumela iipakethi zedatha kwiseva yenethiwekhi ephakathi. Idatha ke ithunyelwa kwiiseva zesicelo. I-teknoloji ibonisa ukuthembeka okuphezulu kumthwalo ophakathi, nangona kunjalo, inemiba ethile yokusebenza ehambelana nokuthumela ukuvuma.
Njengeumenzi wamalungu e-RF asebenzayo, I-Jingxin inokwenza ngokwesiko ukuyila amacandelo ukuxhasa i-LoRaWan. kukho enyeisihluzo somgodi 868MHzisebenza ukusuka kwi-864-872MHz enokuthi isebenze ngokupheleleyo kwesi sisombululo. Iinkcukacha ezithe vetshe zinokunikwa.
