Original Abstract

The unique opportunities introduced by the emerg-ing Industrial Internet of Things (IIoT) applications have accel-erated the momentum of the massive Machine-Type Communications (mMTC) worldwide. As the number of already deployed Low-Power Wide-Area (LPWA) applications growth exponentially over the last decade, new open challenges started to be discussed across the industry sector. The most critical parameter ofthe LWPA devices in question is energy efficiency and the overall power consumption of designed end-devices. Therefore, the needfor precise measurement of power consumption has attracted engineers’ attention as the unique communication parameters ofthe LPWA devices form the current consumption measurements challenging task. To facilitate accurate current measurements ranging between hundreds of nA and hundreds of μA, we propose a unique design of the current probe prototype. We then demonstrate the obtained results concerning the accuracy, measurement range switching, and sufficient sampling speed. All the measurements from the designed prototype are further compared with the industry-grade DC power analyzer AgilentN6705B.
