Abstract
An RFID tag is attached to or embedded in an object and used for determining the position of the object. The RFID tag includes a controller and an energy harvester coupled to the controller. The controller provides object position information to a host device by sending ping signals to the host device. The energy harvester harvests RF energy from WLANs, converts the RF energy to DC power, and supplies the DC power to the RFID tag.
