NB-IoT, or Narrowband Internet of Things, is a low-power cellular communication technology designed to connect devices that send small amounts of data over wide geographic areas. It uses licensed cellular networks and is optimized for devices that need long battery life, reliable connectivity, and relatively low data rates. NB-IoT can support devices in locations where traditional connectivity may be difficult or inefficient.
For example, a utility company can use NB-IoT sensors to remotely report water-meter readings without requiring frequent battery replacement. This reduces maintenance needs and enables automated data collection. NB-IoT is useful for smart metering, environmental monitoring, asset tracking, smart buildings, agriculture, and other applications involving large numbers of low-power connected devices.
