This paper presents the design, implementation and evaluation of In-N-Out, a software-
hardware solution for far-field wireless power transfer. In-N-Out can continuously charge a …

This paper asks:“Can we push the prevailing range limits of commercial passive RFIDs?”.
Today's commercial passive RFIDs report ranges of 5-15 meters at best. This constrains …

Wireless power transfer (WPT) promises to deliver energy to devices that are otherwise hard
to charge or replace batteries for. This paper presents a new power transfer approach by …

Recent innovations significantly advance the communication capabilities of backscatter
networks, while energy harvesting remains the bottleneck of these backscatters. To tackle …

As rapid expansion of the low-cost next billion devices, wireless sensor networks (WSN)
undertake much denser low-end internet of things (IoT) nodes nowadays. In the meantime …

Tiny IoT devices have shown their utilities in many fields. However, due to the low cost, small
form factor, and inherently restricted computation resources, these IoT devices are facing …

For the recent decade, the high-speed development of micro and portable electronic
products meets an important technology barrier, which is the lithium-ion batteries cannot …

Nessa tese o uso de beamforming distribuído em Redes de Sensores Sem Fio é
investigado a partir de uma visão macro da tecnologia. Após uma revisão da literatura em …

In this thesis, we discuss the feasibility of using distributed antenna systems to facilitate the
deployment of IoT devices. Our approaches are inspired by Fresnel zone plates focusing …

Directional modulation is a physical (PHY) layer security technique which corrupts the
modulation format received at non-intended receiver angles while preserving the …
