LoRa je bežična tehnologija za komunikaciju na velikim udaljenostima te ujedno i jedna od najraširenijih
LPWAN tehnologija u svijetu.
LoRa radi odlično u "bučnom" okruženju
Velik domet Mala potrošnja
Mala snaga slanja (25mW) Potrošnja (40mA TX, 10mA RX) U sleep modu, potrošnja manja od 1uA
Slanje male količine podataka
Vremenski limit po uređaju (AirTime)
Semtech SX čipovi za različite frekvencije
EU 868MHz Band SX1276(433Mhz SX1278)
Prima 8 kanala u isto vrijeme
Bolje osjetljivosti nego NOD čipovi
SX1301 -40*C - odlična osjetljivost
SX1308 0*C - manje dobar prijem
Svi čipovi su kontrolirani SPI protokolom
LoRaWAN je (MAC) protokol za WAN (wide area networks).
