LoRa (from "long range") is a physical proprietary radio communication technique based on spread spectrum modulation. It is used as the physical layer for LoRaWAN, a low-power, wide-area network (LPWAN) protocol that wirelessly connects battery-operated devices to the Internet. LoRa can be thought of as the radio signal technology (similar to Wi-Fi or cellular), while LoRaWAN is the protocol and network architecture that manages communication over that signal.
Together, LoRa and LoRaWAN provide a solution for connecting low-power devices over long distances, making them a key technology for the Internet of Things (IoT). The technology is primarily used for applications where small amounts of data need to be transmitted infrequently from hard-to-reach locations, such as in smart agriculture, industrial monitoring, and asset tracking. The technology was originally developed by the French company Cycleo, which was acquired by Semtech in 2012, and the LoRaWAN standard is now managed by the LoRa Alliance.
