  • placing a passive RFID transponder that does not include a power source within a field generated by a power line and the wireless network; and

    enabling the RFID transponder to communicate directly with an RFID reader that is outside of a normal operating range of the RFID transponder by powering the RFID transponder using the field generated by the power line and the wireless network;

    the RFID transponder gaining a set of user rights and controls on the wireless network;

    the RFID transponder gaining a higher priority on the wireless network using the set of user rights and controls;

    the RFID transponder being configured to request a higher level of power;

    from the power line; and
