Most of today’s IoT connections are industrial. Industrial IoT (IoT) connections require Low Power Wide Area (LPWA) technologies to provide connectivity, coverage and subscription capabilities for low bandwidth applications. Although these requirements could be served by existing cellular networks, such networks may not be ideal. NB-IoT (Narrow Band IoT) technology offers a promising solution.
NB-IoT allows IoT devices to operate over carrier networks such as GSM and “guard bands” between LTE channels. NB-IoT needs only 200kHz of bandwidth and can efficiently connect large numbers of endpoint devices (up to 50,000 per NB-IoT network cell). Its low power requirements makes it ideal for use in small, uncomplicated IoT gadgets such as smart parking, utilities and wearables.
