LoRa and LoRaWAN are wireless technologies that enable low-power long-range communication for IoT devices. LoRa is a physical layer modulation technique that allows long-range transmissions, while LoRaWAN is the media access control protocol that defines how devices connect to each other and ensures secure, reliable communication. Together, LoRa and LoRaWAN allow thousands of sensors and devices to connect over distances of several kilometers with battery lives lasting several years. LoRaWAN has benefits like low power consumption, wide area networks, security, and open standards that make it well-suited for many IoT applications.
