LoRaWAN yog cov txheej txheem kev sib txuas lus thiab cov txheej txheem tsim qauv tsim los rau LoRa kev sib txuas lus nyob deb.
LoRa tes hauj lwm yog tsim los ntawm terminals (built-in LoRa modules), rooj vag (los yog chaw nres tsheb hauv paus), network servers, thiab daim ntawv thov servers.LoRaWAN network architecture yog lub hnub qub topology uas LoRa lub rooj vag yog lub pob tw rau pob tshab, txuas cov khoom siv davhlau ya nyob twg mus rau tom qab kawg nrog lub hauv paus server.Cov cuab yeej kawg siv LoRa raws tu qauv los sib txuas lus nrog ib lossis ntau lub rooj vag.Tag nrho cov nodes sib txuas lus nrog lub rooj vag hauv ob qho tib si.
Hauv qee qhov kev siv LoRaWan system, cov ntxaij lim dej yog siv los ua ib txoj hauv kev los xaiv cov zaus bands.
Raws li tus tsim lim dej, Jingxin twb tau tsim ntau yam bandpass lim rau 868MHz band, muaj ib qho kab noj hniav bandpass lim nrog IP67 waterproof rau Lorawan system, nthuav dav ntxiv ntawm https://www.cdjx-mw.com/waterproof-ip65 -bandpass-cavity-filter-operating-from-863-870mhz-jx-cf1-860m870m-40nwp-product/
Yog tias xav tau kev cai tsim lim rau LoRaWan, pls xav nrog peb tham.
