LPWANs are emerging to provide solutions for covering very low-power Internet of Things devices and applications which may be distributed over large geographical areas. LPWANs generally consume very low power thus their batteries can last for a very long time. However, the problem with batteries is that they get damaged with time and they eventually run out. Wireless power transfer on the other hand is gaining popularity for long range wireless networks. Motivated by these developments and the challenge of simultaneously conducting wireless power transfer alongside data communication, this paper proposes the use of magnetically coupled resonance wireless power transfer to power LPWAN devices. This approach allows the increase in distance between the transmitter and receiver and also curb the failure probability and degradation encountered by its coupling. The use of shielding materials and flux guidance is also incorporated into the system in order to increase the efficiency of the system. The analytical solutions to ferrite structures as shielding materials is computed with High Frequency Structure Simulator (HFSS). HFSS is used to compute the S-parameters (input power reflection coefficient and forward power transmission coefficient) of the proposed system and magnetic characteristics by plotting electromagnetic field distributions. |

AB - LPWANs are emerging to provide solutions for covering very low-power Internet of Things devices and applications which may be distributed over large geographical areas.
