LoRa (from "long range") is a physical proprietary radio communication technique. It is based on spread spectrum modulation techniques derived from chirp spread spectrum (CSS) technology. It was developed by Cycleo (patent 9647718-B2), a company of Grenoble, France, later acquired by Semtech. LoRaWAN defines the communication protocol and system architecture. LoRaWAN is an official ITU-T Y.4480 standard of the International Telecommunication Union (ITU).[5] The continued development of the LoRaWAN protocol is managed by the open, non-profit LoRa Alliance, of which SemTech is a founding member.
