LoRaWAN is the communication protocol and system architecture for the network while LoRa is the physical radio layer enabling the long-range communication link. The LoRaWAN protocol and network architecture directly influence the battery lifetime of a node, network capacity, quality of service, security, and the variety of applications served by the network.
LoRa is the technology that modulates the data into electromagnetic waves. It uses a transmission method called “Chirp Spread Spectrum,” encoding data in frequency-modulated “chirps.” This transmission method has been used in military and space communication for decades.
