LoRa VS LoRaWan

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 zithunyelwa 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.
