LoRaWAN (Long Range Wide Area Network)
LoRaWAN is the MAC layer protocol that controls communication between LoRa-devices and LoRa-gateways. LoRaWAN applications operate in globally and regionally different frequency ranges of the ISM and SRD bands.
In Europe, the frequency band from 433.05 to 434.79 MHz (ISM Band Region 1) and from 863 to 870 MHz (SRD Band Europe) is approved for LoRa communication. In North America, the frequency band from 902 to 928 MHz (ISM Band Region 2) is available for use.
Frequency spreading based on chirp spread spectrum modulation enables high efficiency in data transfer and power consumption. At the same time, the modulation used minimizes interference.
LoRaWAN (Long Range Wide Area Network) belongs to the low-power wide area network technologies (LPWAN). The technology operates in the license free wireless frequency spectrum, usually known as ISM (industrial, scientific and medical) radio band. Due to national legislation, these frequencies can differ regionally.
