Abstract

Wireless Power Transfer (WPT) is a promising technique of extending the battery lifetime of battery-powered end-devices (EDs) without getting physical contact between the power transmitter and the ED. At the same time, many of these devices use a long range radio technology to report data of their measurements. Both WPT transmitters and long range radio technologies for Internet of Things (IoT) devices, such as LoRa and Mioty, operate at the same Industrial, Scientific, and Medical (ISM) bands in the sub-GHz spectrum. This paper presents an interference analysis between the two technologies and provides evidences of substantial levels of interference around the US915 Central Frequency (CF) through a number of lab experiments. The results reveal that a number of conditions exist which allow collision-free transmissions (or a very low collision probability) when an ED is transmitting data and receiving energy at the same time.
