Linking up the entire smart city

Narrowband IoT (NB-IoT) is a Low Power Wide Area Network (LPWAN) radio technology developed to connect a wide range of devices and services. As it’s based on the mature LTE network, there is no need to build extra network infrastructure, dramatically reducing total costs. The lower cost and power consumption are in turn spurring the growth of IoT, increasing connections between devices and enabling them to deliver IoT services easily.

Avnet’s NB IoT platform makes it easy for companies to connect a whole gamut of devices for home, industrial and smart city applications like smart metering, parking, street lighting and portable health care. On top of the built-in motion and temperature humidity sensors, more sensors can be added via its Arduino Uno V3 & ST Morpho extension slot. The NB IoT LPWAN also enables raw sensor data to be updated on the cloud.
