NB-IoT (Narrow Band-IoT) is a key technology that plays a crucial role in the integration of low-power CIoT (Cellular Internet of Things) devices, into the mobile network.

This technology is a Low Power Wide Area (LPWA) technology designed specifically for IoT applications that require low data rates, long battery life, and deep indoor coverage. NB-IoT is suitable for ultra-low power consumption, with the ability to operate for several years on a single battery.

NB-IoT operates within the licensed spectrum of cellular networks, leveraging the existing cellular infrastructure, and providing reliable connectivity.

It offers improved coverage, particularly in hard-to-reach locations, such as underground or inside buildings. It uses narrowband radio signals that can penetrate better than traditional cellular signals.

NB-IoT supports a maximum downlink data rate of 27 Kbps, and a maximum uplink data rate of 63 Kbps. And has typical latency in the range of 1.6 to 10 seconds
