NB-IoT stands for Narrowband Internet of Things, which is a low-power, wide-area network (LPWAN) technology designed for connecting a large number of devices and sensors to the Internet of Things (IoT) network.

NB-IoT operates on a narrowband frequency, which allows for long-range and low-power communication between devices. This makes it ideal for use in applications where devices need to be connected over long distances and/or where battery life is a concern, such as in smart cities, smart agriculture, and industrial monitoring.

NB-IoT is based on the existing 4G LTE cellular network, which means that it can be integrated into existing infrastructure with relative ease. It provides reliable and secure communication, with low latency and high throughput, which makes it suitable for a wide range of IoT applications.

Overall, NB-IoT is a powerful technology that is helping to drive the growth of the IoT industry, allowing for the creation of more efficient, connected, and automated systems in a variety of industries.
