Ambient backscatter

Proceedings of the ACM SIGCOMM 2013 conference on SIGCOMM, 2013
We present the design of a communication system that enables two devices to communicate using ambient RF as the only source of power. Our approach leverages existing TV and cellular transmissions to eliminate the need for wires and batteries, thus enabling ubiquitous communication where devices can communicate among themselves at unprecedented scales ...

All Digital Ambient Backscatter System

2020 IEEE Wireless Power Transfer Conference (WPTC), 2020
This work presents an all digital ambient backscatter system which operates with ambient FM sources. Moreover, the system uses commercial modules to perform backscatter and has the ability of using Wi-Fi and Bluetooth signals. The backscatter module presented here uses an ESP32 MCU and a telescopic monopole as an antenna.

Turbocharging ambient backscatter communication

Proceedings of the 2014 ACM conference on SIGCOMM, 2014
Communication primitives such as coding and multiple antenna processing have provided significant benefits for traditional wireless systems. Existing designs, however, consume significant power and computational resources, and hence cannot be run on low complexity, power constrained backscatter devices.
