Abstract:
A method for controlling RF power within an RFID system according to one embodiment includes returning a first set of RFID tags that were successfully accessed at a first reader forward mode power level to a hibernate state; initiating a timer operation in each of the RFID tags within the first set of RFID tags, the timer operation defining a period of time; and preventing the first set of RFID tags from responding to an activation command at a second reader forward power level during the period of time, the second reader forward power level being higher than the first reader forward power level; and wherein a flag state stored in each of the RFID tags within the first set of RFID tags indicates whether the timer operation is active to prevent undesired activation at the second reader forward power level.
