LoRaWAN is a protocol layer specification based on the physical wireless communication technology of lora. The protocol defines what information each paragraph of the transmitted data represents, and also uses AES encryption, which greatly improves the standardization and security of data transmission. It has great competitiveness in low-power wide area networks. The LoRaWAN standard is managed by the technology alliance LoRa Alliance. This standard has been recognized as the LPWAN global standard by the International Telecommunication Union (ITU), the United Nations specialized agency responsible for information and communication technology (ICT).
