The relationship between LoRaWAN and LoRa

　　 Many people confuse the two concepts of LoRaWAN and LoRa. In fact, LoRaWAN refers to the networking protocol of the MAC layer. And LoRa is just a physical layer protocol. Although the existing LoRaWAN networking basically uses LoRa as the physical layer, the LoRaWAN protocol also lists that GFSK can also be used as the physical layer in some frequency bands. From the perspective of network layering, LoRaWAN can use any physical layer protocol, and LoRa can also be used as the physical layer of other networking technologies. In fact, several technologies that compete with LoRaWAN also use LoRa at the physical layer.
