abstract = {The recent standardization of 3GPP Narrowband
Internet of Things (NB-IoT) paves the way to support low-power
wide-area (LPWA) use cases in cellular networks. NB-IoT design
goals are extended coverage, low power and low cost devices,
and massive connections. As a new radio access technology, it is
necessary to analyze the possibilities NB-IoT provides to support
different traffic and coverage needs. In this paper, we propose and
validate an NB-IoT energy consumption model. The analytical
model is based on a Markov chain. For the validation, an experimental
setup is used to measure the energy consumption of two
commercial NB-IoT user equipments (UEs) connected to a base
station emulator. The evaluation is done considering three test
cases. The comparison of the model and measurements is done
in terms of the estimated battery lifetime and the latency needed
to finish the control plane procedure. The conducted evaluation
shows the analytical model performs well, obtaining a maximum
relative error of the battery lifetime estimation between the model
and the measurements of 21% for an assumed interarrival time
(IAT) of 6 min.},
