Wi-Fi Backscattering: A Smart-key to IoT

Enhancing batteryless devices to compute and communicate has been possible by testing the devices with existing RF signals from radio, television. RF signals gets converted into hundreds of microwatts of electricity by these RF-powered devices to transfer data. Such existing RF-powered batteryless devices would expect a dedicated gateway (like RFID reader) for internet connectivity. That’s where Wi-fi Backscattering comes in.
