Abstract

In the last few years, Low Power Wide Area Networks (LPWAN) technologies have been proposed for Machine-Type Communications (MTC). In this paper we evaluate wireless relay technologies that can improve LPWAN coverage for smart meter communication applications. We provide a realistic coverage analysis using a realistic correlated shadow fading map and path loss calculation for the environment. Our analysis shows significant reductions in the number of MTC devices in outage from by deploying either small cells or Device to Device (D2D) communications. In addition, we analysed the energy consumption of the MTC devices for different data packet sizes and Maximum Coupling Loss (MCL) values. Finally, we study how compression techniques can extend the battery lifetime of MTC devices.
