LoRa ipfupi yeLong Range. Iyo yakaderera-chinhambwe, chinhambwe-chinhambwe padhuze-yekusangana tekinoroji. Iyo imhando yenzira, iyo yakakura chimiro chinhambwe chakareba chekutapurirana isina waya munhevedzano imwechete (GF, FSK, nezvimwewo) yakapararira kure, dambudziko rekuyera chinhambwe uye chinhambwe chiripo pamadaro marefu. Inogona kuwedzera 3-5 nguva kupfuura yechinyakare isina waya pasi pemamiriro akafanana.
LoRaWAN chiyero chakavhurika chinotsanangura nzira yekutaurirana yeLoRa chip-based LPWAN tekinoroji uye LoRaWAN inotsanangura Media Access Control (MAC) pane data link layer. Iyo protocol inochengetwa neLoRa Alliance.
LoRaWAN yakaunza zvakajeka sezviri pamusoro apa kuti iprotocol. Iyo inonzi protocol inotsanangura seti yemitemo uye maitiro. Chero LoRaWAN inoenderana node inoda kutevedzera zvinodiwa neLoRaWAN kuti utaure. LoRa inzira yekumisikidza, uye LoRaWAN chishandiso chakavakwa zvinoenderana neLoRa modulation nzira. Zvichitaurwa zviri nyore, iyo LoRaWAN module inoshandisa yakajairwa LoRa module, yobva yaisa paramita kana kutumira uye kugamuchira zvikwangwani zvinoenderana nemimwe mitemo.
Kazhinji kutaura, iyo LoRa node module haigone kutaurirana neLoRaWAN node module, kunyangwe ese maparamita emamodule maviri akafanana.
Sezvo LoRa ichitsanangura iyo yakaderera yemuviri layer, epamusoro networking akashaikwa. LoRaWAN ndeimwe yemaprotocol akati wandei akagadzirwa kuti atsanangure mativi epamusoro etiweki. LoRaWAN igore-based medium access control (MAC) layer protocol, asi inoshanda zvakanyanya setiweki layer protocol yekutarisira kutaurirana pakati peLPWAN gedhi nemagumo-node zvishandiso senzira yekufambisa, inochengetwa neLoRa Alliance.
LoRaWAN inotsanangura iyo protocol yekutaurirana uye sisitimu yekuvaka yetiweki, nepo LoRa yemuviri layer inogonesa iyo yakareba-renji yekutaurirana link. LoRaWAN inewo basa rekugadzirisa mafambiro ekutaurirana, chiyero chedata, uye simba kune ese maturusi. Midziyo iri munetwork ndeye asynchronous uye inotapurirana kana iine data iripo yekutumira. Dhata inofambiswa neyekupedzisira-node mudziyo inotambirwa nemagedhi akawanda, ayo anoendesa mapepa e data kune yepakati network server. Data inozoendeswa kune maseva ekushandisa. Iyo tekinoroji inoratidza kuvimbika kwakanyanya kune ine mwero mutoro, zvisinei, ine mamwe maitiro ekuita ane chekuita nekutumira kubvuma.
Sezvomugadziri weRF passive components, Jingxin inogona kugadzira dhizaini zvikamu zvekutsigira LoRaWan. pane imwemhango sefa 868MHzinoshanda kubva ku864-872MHz iyo inogona kushanda zvachose kune iyi mhinduro. Mamwe mashoko anogona kupiwa.
Nguva yekutumira: Feb-25-2022
