Info
- LoRa is the physical layer or in simple words is the modulation, the modem or radio, the hardware.
- LoRaWAN is the network protocol or architecture that works on LoRa.
Lora
LoRa ™ is a long-range radio technology "Lo ng- Ra nge" its main features:
- Its spread spectrum modulation allows a significantly greater scope to other technologies.
- High sensitivity (-168dB) combined with high immunity to interference.
- Low Consumption (up to 10 years with a battery, good depends on certain characteristics).
- Low data transfer (up to 255 bytes).
