NB-IoT: How Narrowband IoT Supports Massive Connected Devices

NB-IoT (Narrowband Internet of Things) is a cellular LPWAN technology designed for connecting large numbers of low-power devices that transmit small amounts of data over long periods, such as sensors, smart meters, and trackers. Standardized by 3GPP and operating in licensed spectrum, NB-IoT leverages existing LTE networks and uses mechanisms like Power Saving Mode (PSM) and eDRX to extend battery life for years. It is commonly used in smart cities, smart metering, asset tracking, environmental monitoring, and industrial applications. While efficient for low-data, wide-area connectivity, NB-IoT has limited throughput and higher latency, making it less suitable for real-time or high-bandwidth applications, and it complements other technologies like LTE-M and 5G in the IoT ecosystem.
