On the Energy Coverage of Low Power Wide Area Networks (LPWANs) Wireless Powered by Ultra-Dense MmWave Small Cells
Abstract
The low power wide area networks (LPWANs) are recently emerging to provide coverage for low- power devices distributed over very large areas. In order to further prolong the battery life of LPWAN devices, in this paper we propose to power LPWAN devices with radio frequency (RF) energy provided by 1) small-cell networks over millimeter-wave (mmWave) frequency bands, and 2) a macrocell base station (MBS) equipped with massive antennas over sub-6 GHz bands. By modeling the mmWave small-cell base stations (SBSs) as a homogeneous Poisson point process and applying stochastic geometry, the energy coverage for each LPWAN device is analyzed. Moreover, the ultra- dense mmWave SBSs case is further discussed by applying a simplified pathloss model. Our results show that ultra-dense mmWave SBSs are capable of powering a large number of LPWAN devices.
