Abstract
System, methods and computer program product are provided for an adaptive control for adjusting the electromagnetic interrogation signal of an RFID transceiver where said signal is used to read and/or write to an RFID transponder (702) , or to adjust the gain of the RFID transceiver, or adjust both the gain and the signal strength. The system includes a RFID transceiver (708) having at least a transmitter portion and a receiver portion and capable of generating electromagnetic signals, a signal-to-noise ratio module (710) , and an adaptive control module (712) that adjusts the power of the electromagnetic signal of the transmitter portion or the gain of the receiver portion according to the signal-to-noise ratio of a first electromagnetic signal . In one embodiment the system may be employed in printer-encoder devices for reading or encoding RFID transponders during a printing process.
