NB-IoT, or Narrowband Internet of Things, is a low-power wide-area network (LPWAN) technology designed for connecting a large number of devices over long distances. It operates on existing cellular networks, making it cost-effective and easy to deploy. NB-IoT is particularly suited for applications that require small amounts of data transmission, such as smart meters, environmental monitoring, and asset tracking. One of the key advantages of NB-IoT is its ability to penetrate deep into buildings and underground areas, ensuring reliable connectivity in challenging environments. Additionally, it offers extended battery life for connected devices, often lasting several years on a single charge. This makes NB-IoT an ideal choice for various industries looking to implement IoT solutions efficiently.
