  Low Power Wide Area Networks (LPWAN) are expected to play an important role
in the deployment of the Internet of Things (IoT). One of the major advantages
of LPWAN is the low power consumption characteristics which allow devices to be
deployed without the restriction of power supply when battery is contained, in
consequence the Lifetime estimation metric is of high relevance. This article
provides a method for evaluating the Lifetime Estimation of battery powered
LPWAN End Points, a depiction of the LPWAN architecture together with a
breakdown of second order effects of the model are analyzed.
