LoRa VS Yokohama

LoRa ni ngufi kuri Long Range. Nintera-ndende, intera-intera yegeranye-tekinoroji. Nubwoko bwuburyo, ikintu kinini kiranga ni intera ndende yohereza imiyoboro idafite umurongo mugihe kimwe (GF, FSK, nibindi) ikwirakwira cyane, ikibazo cyo gupima intera nintera ibana kure. Irashobora kwaguka inshuro 3-5 kurenza umugozi gakondo mubihe bimwe.

LoRaWAN ni igipimo gifunguye gisobanura protocole y'itumanaho ya tekinoroji ya LPR ya chip ya LoRa naho LoRaWAN isobanura igenzura ry'itangazamakuru (MAC) murwego rwo guhuza amakuru. Porotokole ikomezwa na LoRa Alliance.

LoRaWAN yerekanye neza nkuko byavuzwe haruguru ko ari protocole. Ibyo bita protocole byerekana urutonde rwamategeko n'inzira. Ikintu cyose cyujuje LoRaWAN gikeneye gukurikiza ibisabwa na LoRaWAN kugirango tuvugane. LoRa nuburyo bwo guhindura, kandi LoRaWAN ni porogaramu yubatswe ukurikije uburyo bwo guhindura LoRa. Muri make, module ya LoRaWAN ikoresha module isanzwe ya LoRa, hanyuma igashyiraho ibipimo cyangwa ikohereza kandi yakira ibimenyetso ukurikije amategeko amwe.

Mubisanzwe, LoRa node module ntishobora kuvugana na module ya LoRaWAN, nubwo ibipimo byose bya module byombi ari bimwe.

Kubera ko LoRa isobanura urwego rwo hasi rwumubiri, urwego rwo hejuru rwurusobe rwabuze. LoRaWAN ni imwe muri protocole nyinshi zakozwe kugirango zisobanure urwego rwo hejuru rwurusobe. LoRaWAN ni igicu gishingiye ku gicu giciriritse cyo kugenzura (MAC) protocole, ariko ikora cyane nka protocole y'urusobekerane rwo gucunga itumanaho hagati y'amarembo ya LPWAN n'ibikoresho byanyuma nka protocole ya maritike, ikomezwa na LoRa Alliance.

LoRaWAN isobanura protocole y'itumanaho hamwe na sisitemu yubatswe kuri neti, mugihe LoRa igaragara ifasha itumanaho rirerire. LoRaWAN ishinzwe kandi gucunga imirongo yitumanaho, igipimo cyamakuru, nimbaraga kubikoresho byose. Ibikoresho murusobe ntibisanzwe kandi byohereza mugihe bifite amakuru aboneka yohereza. Amakuru yoherejwe nigikoresho cyanyuma-cyakiriwe n amarembo menshi, yohereza paki yamakuru kuri seriveri ihuriweho. Ibyatanzwe noneho byoherejwe kuri seriveri ya porogaramu. Tekinoroji yerekana kwizerwa cyane kumutwaro uciriritse, ariko, ifite ibibazo bimwe byimikorere bijyanye no kohereza ibyemezo.

Nkauwakoze RF ibice bigize pasiporo, Jingxin irashobora gushushanya ibice kugirango ishyigikire LoRaWan. hariho imweakayunguruzo ka cavity 868MHzikora kuva 864-872MHz ishobora gukora rwose kubwiki gisubizo. Ibisobanuro birambuye birashobora gutangwa.
