Wi Fi Backscatter Internet Connectivity For 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. Wi-Fi Backscatter Internet Connectivity for RF-Powered Devices Most existing chipsets only provide RSSI information A metric for cumulative signal strength across all the sub- channels Can have multiple RSSI channels multiple antennas. Specifically we show that it is possible to reuse existing Wi-Fi infrastructure to provide Internet connectivity to RF-powered devices. We use off-the-shelf Wi-Fi devices including Intel Wi-Fi.
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. Connecting RF-Powered Devices to the Internet. We present Wi-Fi Backscatter a novel communication system that bridges RF-powered devices with the Internet. 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 present Wi-Fi Backscatter a novel communication system that bridges RF-powered devices with the Internet. We convey a 1 bit by reflecting Wi-Fi packets and transmit a 0 bit by.

Specifically we show that it is possible to reuse existing Wi-Fi infrastructure to provide Internet connectivity to RF-powered devices. Connecting RF-Powered Devices to the Internet. These devices can communicate with other devices using backscatter technique. Wi-Fi Device Wi-Fi Backscatter Tag -Fi AP 2 4 Key Idea.
