We present Wi-Fi Backscatter a novel communication system that bridges RF-powered devices with the Internet. Specifically we show that it is possible to reuse existing Wi-Fi infrastructure to provide Internet connectivity to RF-powered devices.

Speciﬁcally we show that it is possible to reuse existing Wi-Fi infrastructure to provide Internet connectivity to RF-powered devices.

Wi fi backscatter internet connectivity for rf powered devices. We present Wi-Fi Backscatter a novel communication system that bridges RF-powered devices with the Internet. Specifically we show that it is possible to reuse existing Wi-Fi infrastructure to provide Internet connectivity to RF-powered devices. To show Wi-Fi Backscatters feasibility we build a hardware prototype and demonstrate the first communication link between an RF-powered device and commodity Wi-Fi devices.

We use off-the-shelf Wi-Fi devices including Intel Wi-Fi. Wi-Fi Backscatter is a novel communication system that enables RF-powered devices to communicate directly with commodity Wi-Fi devices. As shown in Fig.

Smith and David Wetherall University of Washington kellogg anparks gshyam jrsjrs djwuwedu Abstract RF-powered computers are small devices that com-pute and communicate using only the power that they harvest from RF signals.

Municate directly with commodity devices. While recent work on passive Wi-Fi 28 signiﬁcantly reduces the power consumption of Wi-Fi transmissions using backscatter com-munication it requires infrastructure support in the form of specialized hardware that can generate the continuous wave RF signal needed for backscattering Wi-Fi signals.

To show Wi-Fi Backscatters feasibility we build a hardware prototype and demonstrate the first communication link between an RF-powered device and. RF-powered computers are small devices that compute and communicate using only the power that they harvest from RF signals. While existing technologies have harvested power from ambient RF sources eg TV broadcasts they require a dedicated gateway like an RFID reader for Internet connectivity.

We present Wi-Fi Backscatter a novel. This technology lets Internet connectivity to RF powered devicesRf powered devices are those devices which charge their batteries from surrounding Radio Frequency signals present. These devices can communicate with other devices using backscatter technique.

This is accomplished using radio frequency RF backscatter technology to extract the power that exists as reflected energy each time a wireless router or other RF device broadcasts a signal within the Wi-Fi infrastructure. Motivation and Challenes Motivation. WiFI connectivity for low power devices.

WiFi transmission require much more energy than other RF applications. WiFi devices can only access WiFi signals. RF-powered tags cannot speak Wi-Fi Energy consumption Hardware limitations It is not clear how Wi-Fi devices decode signals from RF-powered devices 7 Wi-Fi Backscatter A novel communication system that solves above challenges making RF-powered things directly communicate with Wi-Fi devices.
