I-LoRa VS LoRaWan

I-LoRa imfushane ku-Long Range.Ibanga eliphansi, ubuchwepheshe bokuxhumana eduze nebanga lebanga.Kuwuhlobo lwendlela, isici sayo esikhulukazi okuyibanga elide lokudluliswa okungenantambo ochungechungeni olufanayo (i-GF, i-FSK, njll.) lusakazekela kude, inkinga yokulinganisa ibanga nebanga elikhona ebangeni elide.Inganweba izikhathi ezi-3-5 ngaphezu kocingo oluvamile ngaphansi kwezimo ezifanayo.

I-LoRaWAN iyindinganiso evulekile echaza iphrothokholi yokuxhumana yobuchwepheshe be-LPWAN obusekelwe ku-chip ye-LoRa futhi i-LoRaWAN ichaza i-Media Access Control (MAC) kusendlalelo sesixhumanisi sedatha.Iphrothokholi igcinwa yi-LoRa Alliance.

I-LoRaWAN yethule ngokucacile njengokungenhla ukuthi iyiphrothokholi.Okubizwa ngokuthi iphrothokholi icacisa isethi yemithetho nezinqubo.Noma iyiphi inodi ethobelayo ye-LoRaWAN idinga ukulandela izimfuneko ze-LoRaWAN ukuze uxhumane.I-LoRa iyindlela yokushintshashintsha, futhi i-LoRaWAN iwuhlelo lokusebenza olwakhiwe ngendlela ye-LoRa yokushintshashintsha.Kalula nje, imojula ye-LoRaWAN isebenzisa imojuli ye-LoRa evamile, bese isetha imingcele noma ithumele futhi yamukele amasignali ngokuvumelana nemithetho ethile.

Ngokuvamile, imojula yenodi ye-LoRa ayikwazi ukuxhumana nemojula yenodi ye-LoRaWAN, noma ngabe wonke amapharamitha amamojula amabili afana.

Njengoba i-LoRa ichaza ungqimba oluphansi lomzimba, izendlalelo eziphezulu zenethiwekhi bezishoda.I-LoRaWAN ingenye yezivumelwano ezimbalwa ezakhiwe ukuze zichaze izendlalelo eziphezulu zenethiwekhi.I-LoRaWAN iyiphrothokholi yesilawuli sokufinyelela okumaphakathi esisekelwe efwini (i-MAC), kodwa isebenza ngokuyinhloko njengephrothokholi yesendlalelo senethiwekhi yokuphatha ukuxhumana phakathi kwamasango e-LPWAN namadivayisi e-end-node njengephrothokholi yomzila, egcinwa yi-LoRa Alliance.

I-LoRaWAN ichaza iphrothokholi yokuxhumana kanye nesakhiwo sesistimu yenethiwekhi, kuyilapho isendlalelo esibonakalayo se-LoRa sivumela isixhumanisi sokuxhumana sebanga elide.I-LoRaWAN futhi inesibopho sokuphatha amaza okuxhumana, isilinganiso sedatha, namandla awo wonke amadivayisi.Amadivayisi akunethiwekhi awavumelanisi futhi adlulisa lapho anedatha etholakalayo yokuthumela.Idatha edluliswa idivayisi ye-end-node itholwa ngamasango amaningi, adlulisela amaphakethe edatha kuseva yenethiwekhi ephakathi nendawo.Idatha ibe isidluliselwa eziphakelini zohlelo lokusebenza.Ubuchwepheshe bubonisa ukuthembeka okuphezulu komthwalo omaphakathi, nokho, bunezinkinga ezithile zokusebenza ezihlobene nokuthumela ukuvuma.

Njengoba iumenzi wezingxenye ze-RF ze-passive, i-Jingxin ingaklama ngokwezifiso izingxenye ezisekela i-LoRaWan.kukhona oyedwaIsihlungi somgodi 868MHzisebenza kusuka ku-864-872MHz engasebenza ngokuphelele kulesi sixazululo.Imininingwane eyengeziwe inganikezwa.
