An Experimental Evaluation of NB-IoT Coverage and Energy Consumption

5G is expected to accelerate the digitalization of industry and society by means of not only ubiquitous connected people but also connected devices. One important feature on 5G roadmap is the provision of 5G massive Internet of Things (IoT) service. This paper will introduce the key mobile IoT technology, Narrowband IoT (NB-IoT) and evaluate its performances in a practical test environment.
