We discuss the division of radio resources in the time and frequency domains for wireless local area network (WLAN) devices powered with microwave energy. In general, there are two ways to avoid microwave power transmission (MPT) from influencing data communications: adjacent channel operation of continuous MPT and WLAN data transmission and co-channel(More)
In this paper, we study the feasibility of a batteryless wireless sensor supplied with energy by using microwave power transmission (MPT). If we perform co-channel operation of MPT and wireless local area networks (WLANs) for the sake of spectral efficiency, a time division method for MPT and WLAN communications is required to avoid serious interference(More)
In wireless sensor networks, individual nodes must be batteryless to make themselves maintenance-free, which is particularly important for networks that have an enormous number of nodes. Wireless and batteryless sensors can be powered by energy harvesting or wireless power transmission, and they store energy in capacitors. Microwave power transmission is a(More)
