TL;DR: PLoRa takes ambient LoRa transmissions as the excitation signals, conveys data by modulating an excitation signal into a new standard LoRa "chirp" signal, and shifts this new signal to a different LoRa channel to be received at a gateway faraway.

TL;DR: This article comprehensively review the state-of-art of HBR, based on the two techniques that drove recent progress in Wi-Fi channel-state-information-based HBR -- fingerprint-based and model-based, and provides a performance comparison of the two mechanisms.

TL;DR: In-N-Out can continuously charge a medical implant residing in deep tissues at near-optimal beamforming power, even when the implant moves around inside the human body, and is sufficient to wirelessly power a range of commercial medical devices.

TL;DR: In-N-Out as mentioned in this paper, a software-hardware solution for far-field wireless power transfer, can continuously charge a medical implant residing in deep tissues at near-optimal beamforming power, even when the implant moves around inside the human body.

TL;DR: R&P, a device-free activity recognition system only using cheap radio frequency identification devices (RFID) tags is introduced, based on the analysis of RFID signals, where received signal strength fingerprints and phase fingerprints for each activity are extracted and synthesized to accurately recognize activities.
