Abstract The agricultural Internet of Things (Ag-IoT) paradigm has tremendous potential in
transparent integration of underground soil sensing, farm machinery, and sensor-guided …

In this paper, we study a multi-antenna wireless-powered sensor network (WPSN), in which
a power beacon wirelessly transfers electric energy to a sensor node via an electromagnetic …

A wireless rechargeable sensor network (WRSN) consists of sensor nodes that can harvest
energy emitted from wireless chargers for refilling their batteries so that the WRSN can …

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 …

This paper proposes a rate adaptation scheme (RAS) for a wireless local area network
(WLAN) station powered with microwave power transmission (MPT). A WLAN station …

In order to efficiently drive a low-power DC motor using microwave power transfer (MPT), a
compact power-receiving device is developed, which consists of a rectenna array and an …

This paper proposes to improve effectiveness of supplying a sensor with energy using
microwave power transmission (MPT) and energy harvesting (EH). The MPT duration should …

Abstract The 2.4-GHz frequency band is a good candidate for wireless power transmission
(WPT)[1]. Because numerous wireless local area network (WLAN) devices use the 2.4-GHz …

This thesis aims to efficiently utilize radio spectrum and tackles coexistence problems of
wireless communication and non-communication systems on the assumption that both …

Numerous studies have been carried out on the wireless power transmission (WPT)
technologies, which transfers power to the electrical loads without man-made wires. As one …
