-139dbm umamukeli wedatha ezwelayo yokudlulisa imojula eshumekiwe ye-LoRa DTU
Itheminali eshumekiwe ye-LORA DTU module_MDL210 yileyo esebenzisa ubuchwepheshe be-LoRa spread spectrum ekudluliselweni kwedatha okungenantambo, ihlinzeka abasebenzisi ngemodi yokudlulisa idatha esobala ngokugcwele engenaphrothokholi.Udinga kuphela ukusetha amapharamitha ambalwa ukuze uzuze izindlela eziningi zokuxhumana ezifana nenkanyezi enenethiwekhi nenethiwekhi ye-Mesh. Kukhona futhi izindlela eziningi zokuxhumana ezifana nokufunwayo, ukusakaza, nokusakaza okuningi kunethiwekhi efanayo;
I-TTL zokuxhumana ihlinzeka nge-interface enikezwayo, inethiwekhi yemishini ye-serial port ye-industrial esebenziseka kalula, ukunikezwa kwamandla kagesi kusebenzisa idizayini ebanzi yokusetshenziswa kwamandla okuphansi(≤40uA@5V).
Ubuchwepheshe be-LoRa ngokwabo bunokuzwela kwerecei ephezulu kakhulu (RSSI) kanye
i-super signal-to-noise (SNR) kanye nobuchwepheshe bethu bokusekela bemodemu yobunikazi kanye nokusebenza komkhiqizo okuzinzile nokuthembekile.
Imojula engenantambo ye-LoRa inekhono eliqinile lokulwa nokuphazamiseka.
I-MDL210 ibambisana ne-4G DTU yenkampani yethu, engasiza ekusungulweni kwesango le-LoRa ukuze kutholakale ukudluliswa kwedatha okukude.
Ukuxhumana kokusakaza
Ngaphansi kwenethiwekhi efanayo, idivayisi ngayinye ixhumana nenye
Iphuzu - iphuzu lokuxhumana
Ngaphansi kwenethiwekhi efanayo, ukuxhumana kwephoyinti
phakathi kwanoma yimaphi amadivaysi amabili angabonakala
Ukuxhumana kokusakaza okuningi
Ngaphansi kwenethiwekhi efanayo, idivayisi eyodwa noma eziningi zingasethwa njengeqembu ukuze kutholakale ukuxhumana kweqembu neqembu
Izindlela ezintathu zokuxhumana ezingenhla zingahlanganiswa kunethiwekhi efanayo
Ngaphezu kokusebenzisa ikhebula le-serial lasendaweni ukuze ulungiselele ngokuqondile imingcele yedivayisi ye-MIND LoRa,iphinde isekele ngokungenantamboukulungisa amapharamitha wedivayisi ekude.
Njengoba kuboniswe ku-FIG:
Idivayisi A ixhunywe kukhompuyutha ngekhebula le-serial, futhi isofthiwe yokumisa isithombe enikezwe inkampani yethu ingasetshenziswa ukulungisa amapharamitha wedivayisi yasendaweni A kalula nangokushesha, futhi nemingcele yedivayisi ekude B nayo ingalungiselelwa. ngokungenantambo.
*Ukuze ulungiselele amapharamitha kumodi engenantambo, qinisekisa ukuthi idivayisi yasendaweni nesilawuli kude kunethiwekhi efanayo

Kusukela ngo-2015, inkampani yethu isiqalile ukuthuthukisa nokukhiqiza imikhiqizo yochungechunge lwe-LoRa, ngokuthunyelwa okuhlanganisiwe kwamayunithi angaphezu kuka-5,000. Eminyakeni emibili edlule, imikhiqizo yochungechunge lwe-LoRa isetshenziswe ngempumelelo kuphrojekthi "Isixwayiso Sokuqala Sezinhlekelele Zezikhukhula Zikazwelonke" inkampani yethu ebambe iqhaza kuyo. Amaqiniso afakazele ukuthi thina Ngekhwalithi yayo ephezulu, ukuzinza okuphezulu, kanye nesiqinisekiso esiphezulu. izici, imikhiqizo yayo iqashelwe embonini futhi inegama elihle phakathi kwamakhasimende.
