We present the design of a communication system that enables two devices to communicate using ambient RF as the only source of power. [] Key Method Our design avoids the expensive process of generating radio waves; backscatter communication is orders of magnitude more power-efficient than traditional radio communication. Further, since it leverages the ambient RF signals that are already around us, it does not require a dedicated power infrastructure as in traditional backscatter communication. To show the…

Achievable information rates of ambient backscatter communications
TLDR
The ultimate performance limits of ambient backscatter systems in broadband fading environments are considered, by considering different amounts of network state information at the receivers, and it is found that a legacy system employing multicarrier modulation can turn the RF interference arising from the backscattering process into a form of multipath diversity that can be suitably exploited to noticeably increase its performance.
