The technology relevant for Internet of Things (IoT) devices to communicate effectively is low-power wide-area network (LPWAN) technology. LPWAN enables long-range communication between IoT devices while consuming minimal power, making it ideal for battery-operated sensors and devices that require extended battery life. Protocols like LoraWAN and NB-IoT are examples of LPWAN technologies designed to facilitate reliable connectivity in various applications, including smart cities, agriculture, and industrial automation. This technology is pivotal for scaling IoT networks efficiently.
