Description

The sustainable development of the Internet of Things (IoT) hinges on communication solutions that are battery-less, minimal in hardware complexity, and capable of operating near the optimal trade-off between data and power reception. Traditionally, the balance between downlink data and power transfer has been explored through various forms of splitting and conventional communication methods. In this paper, we introduce two novel approaches that enable simultaneous and unified receivers, capable of rectifying power and demodulating information from the same received signal using identical analog low-power hardware. We demonstrate how information can be encoded in both amplitude and frequency, and how hardware-induced non-idealities can be mitigated or even leveraged. Our goal is to bring these unified receivers to the forefront of the IoT community's attention, and outline several open problems that warrant further investigation.
