Abstract
In general, embodiments of the present invention provide approaches for providing power to RFID transponders. In one embodiment, the RFID transponder is powered using a magnetic field generated by power lines. In another embodiment, the RFID transponder is powered using a field generated by a wireless network. In the case of the latter, the RFID transponder acts as a member of the wireless network. In so doing, the RFID transponder is granted user rights and controls, and can control devices that are available on the network
